A few weeks ago my email konto got hacked. The hacker also also deleted it. Now i cant log in in video games and in microsoft itsself but in like Disney or Gmail. I also went to the microsoft support but it dont work because they want to sent a code to a phone number or email(the email has @neplys in it) I dont know. Does somebody know my problem and could help me?21Views0likes0CommentsStop restricting the agent. Start restricting its environment.
Human review improves safety but limits autonomy. Standing credentials preserve autonomy but increase risk. With Azure SRE Agent, we found a safer middle by moving control out of the model and into the runtime around it.704Views1like1CommentCreate a CLI and API like wslc but for Windows containers
The current issue is the dependency on Docker and the docker cli for Windows Containers. We would like a native solution from Microsoft for Windows Containers. This would be similar to wslc, but fully compatible for Windows containers. This could be done by leveraging existing Windows container APIs and the containerd container engine for Windows containers. I have also opened an enhancement feature on github for Windows Containers a month ago but there has been no feedback. https://github.com/microsoft/Windows-Containers/issues/643 Microsoft needs to step up and make Windows/ Windows Server containers on par with linux containers66Views0likes0CommentsAzure Container Apps Sandboxes (Preview): Giving AI Agents a Safe Place to Work
Co-written by Nikoloz Buligini, Front End Developer at Templafy, and Jan Kalis, Azure Container Apps Sandboxes, Core AI, Microsoft Every team building with multi-tenant AI agent platforms hits the same wall. The agent is smart enough to read your code, reason about a bug, and propose a fix. But the moment it needs to take an action - clone a repo, install tooling, run a command, hit an internal endpoint - you have to answer some uncomfortable questions: where does it run, what permissions does it have and what can it access? Run it on your own infrastructure and inherit the blast radius. Give it broad network access and you have handed an autonomous process the keys to your environment. Lock it down too hard and the agent cannot do its job. This is exactly the problem Azure Container Apps Sandboxes was built to solve. And it is exactly the problem the team at Templafy solved in production. This post walks through what Sandboxes are, the features that make them a good fit for agentic workloads and how Templafy put ACA Sandboxes to work. What are Azure Container Apps Sandboxes? Azure Container Apps Sandboxes (Preview) are secure, isolated compute environments that start in seconds, scale to thousands, and do not charge you for compute while stopped. Each sandbox runs inside its own hardware-isolated microVM, fully separated from the host, the platform, and every other sandbox. Bring your own container image or use an included one, and Sandboxes handle provisioning, isolation, and lifecycle. This is the same compute fabric behind products like Cloud sandboxes in GitHub Copilot, Foundry Hosted Agents, and Azure Container Apps Express, and now you can build directly on it. For platform builders, that means enterprise-grade, multi-tenant isolation as a building block you would otherwise spend years creating. For AI agents, a sandbox becomes a self-configurable tool: spin up a fresh environment in seconds, run untrusted code, compile a project, or explore a codebase, then throw it away. On one side you empower humans to build platforms. On the other you empower agents to extend their own capabilities. The features that make Sandboxes fit agentic work A fast microVM is table stakes. What makes Sandboxes practical for real agent workloads is the control around them. Snapshots capture a fully configured environment and resume from it, ideal for long-running tasks or cloning setups. Egress controls declare exactly what a sandbox may reach, so an agent can pull from source control and package registries but nothing you did not approve. Managed identities authenticate to Azure with no secrets in the image. Automatic suspend and resume map cleanly onto how conversational agents behave, warming back up with full context when a conversation continues. Ports give your orchestrator a channel to a long-running agent process inside the sandbox. Two newer capabilities go further: virtual network integration puts an agent workspace inside your own Azure VNet with access to private endpoints, and bring your own storage lets data and artifacts outlive a session under your compliance rules. Together these turn a fast disposable VM into something you can hand to an autonomous agent in production. Which brings us to Templafy. How Templafy uses Sandboxes, in their own words The following section is written by Nikoloz, Front End Developer at Templafy. At Templafy we built an AI agent that helps our teams by doing longer-running source-code exploration on their behalf. Someone asks a question in a Slack thread, and behind the scenes the agent needs a real, isolated workspace where it can clone repositories, run tooling, and dig through code without touching anything it should not. It started as an engineer-facing tool for deep technical questions, but we recently opened it up to our product team for questions about undocumented product behavior. There, the agent first checks our Help Center through Azure AI Search with no sandbox required and only spins up a sandbox to explore the code when the docs come up short. Since these users aren't engineers, we summarize what the exploration finds into something more approachable. Funnily enough, the product team has been using it more than engineering does, and the feedback since launch has been great. We needed strong isolation, fast startup, and tight control over what each workspace could reach. Azure Container Apps Sandboxes gave us exactly that. We were sold on the model early enough that we built our own TypeScript SDK for Sandboxes before there was an official one, so we could drive the whole lifecycle from our Node stack. Here is what happens when the AI decides to start a workflow for a Slack thread: Create a sandbox from the public node-24 image. Install Git and other development tools. Clone our repositories and configure OpenCode. Restrict egress to only the Azure DevOps, package registry, and service endpoints the agent actually needs. Expose a port used to communicate with the agent runtime. Create and reuse snapshots so we do not repeat the bootstrap process on every run. Associate successful sessions with their Slack threads for a short period, so users can make follow-up requests against the same warm workspace. Stop or suspend idle sandboxes and resume them when a conversation continues. Delete failed or expired sessions. To do all of this we lean on the SDK for the full surface area: sandbox lifecycle operations, command execution, files, snapshots, ports, egress policies, public disk-image inspection, and sandbox state. Two features carry most of the weight for us. The first is restricted egress. Our agent is autonomous and works with our source code, so we are not comfortable letting it talk to the open internet. Declaring a narrow allow-list of endpoints means the workspace can do its job and nothing more, and that control is what let us ship this with confidence. The second is snapshots. Cloning repositories and configuring the toolchain is not free and doing it on every Slack message would make the agent feel slow. With snapshots we pay that cost once and resume from a ready-to-work state, so follow-ups in a thread start fast. This is only the first workflow. We are already looking at background investigations using Application Insights and eventually letting the agent open pull requests for quick bug fixes. The same isolated-workspace pattern extends cleanly to all of it. Who this is for If you are building an AI agent that needs to run code, explore a repository, or reach into your systems, and you have been nervous about where that runs, ACA Sandboxes is for you. You do not have to choose between a capable agent and a safe one. Give it a hardware-isolated workspace, declare exactly what it can touch, snapshot the setup, and let it work. Templafy went from "how do we let an agent safely explore our source code" to a production workflow running out of Slack threads, on infrastructure they controlled end to end. The building blocks are the same ones you can pick up today.

By Johnson Shi, Aviral Takkar, Bin Du Introduction Two of the most common networking questions we hear from teams running Azure Container Registry (ACR) are: "Can my registry serve clients on IPv6 networks?" — Teams operating IPv6-only or dual-stack networks need their container registry reachable over IPv6. "How do we start moving registry traffic toward IPv6 without breaking anything?" — Organizations guarding against IPv4 address exhaustion, or operating under IPv6 transition mandates, want a migration path that doesn't disrupt existing IPv4 clients. Today, we're announcing the public preview of IPv6 dual-stack endpoints for Azure Container Registry for public endpoints and firewall rules, with IPv6 over private endpoints planned for GA. Set your registry's endpoint protocol to IPv4AndIPv6 , and its endpoints become reachable over both IPv4 and IPv6 — so IPv4-only, dual-stack, and IPv6-capable clients all connect to the same registry, each over whichever protocol their network stack selects. Key Takeaways ACR registries now support an endpointProtocol setting with two values: IPv4 (default) and IPv4AndIPv6 (dual stack, preview). Dual stack is additive — your registry continues serving IPv4 clients exactly as before. There is no IPv6-only mode. Dual stack requires dedicated data endpoints to be enabled ( --data-endpoint-enabled true ), and dedicated data endpoints require the Premium SKU. The service enforces this requirement. You can enable it today with Azure CLI 2.87.0 via az acr update --endpoint-protocol IPv4AndIPv6 . FQDN-based client firewall rules keep working unchanged; IP-based allowlists need to account for IPv6 traffic. Limitation: This public preview covers IPv6 for the registry's public endpoints and firewall rules only. IPv6 over private endpoints is planned for a future release. Limitation: ACR Tasks isn't supported on a registry that has IPv6 dual-stack enabled. Tasks does not work when the endpoint protocol isIPv6 dual-stack, including quick builds (with az acr build) and quick task runs (with az acr run). Support is planned for a future release. How to enable it On an existing registry (Azure CLI 2.87.0 or later) Dual stack requires dedicated data endpoints, so enable both in a single update: az acr update --name <your-registry> --data-endpoint-enabled true --endpoint-protocol IPv4AndIPv6 If dedicated data endpoints are already enabled, set the endpoint protocol on its own: az acr update --name <your-registry> --endpoint-protocol IPv4AndIPv6 Verify the configuration: az acr show --name <your-registry> --query "{endpointProtocol:endpointProtocol, dataEndpointEnabled:dataEndpointEnabled}" { "dataEndpointEnabled": true, "endpointProtocol": "IPv4AndIPv6" } Note: If your clients sit behind a firewall and you're enabling dedicated data endpoints for the first time, add firewall rules for <your-registry>.<region>.data.azurecr.io before enabling — switching from *.blob.core.windows.net to dedicated data endpoints changes where layer blobs are downloaded from. See Dedicated data endpoints for details. Reverting to IPv4 Dual stack is reversible at any time: az acr update --name <your-registry> --endpoint-protocol IPv4 Reverting the endpoint protocol leaves dedicated data endpoints enabled; disable them separately if desired. Scope of this preview This public preview enables IPv6 for the registry's public endpoints — the login server, dedicated data endpoints, and regional endpoints (if enabled). IPv6 over private endpoints isn't part of this preview. Support is planned for a future release. Until then, registries reached through a private endpoint continue to use IPv4. Additionally, IPv6 dual-stack support for ACR Tasks, including support for `az acr build` and `az acr run`, are not supported in the public preview. Support is planned for a future release. Requirements and how features compose Requirement Why Premium SKU Dedicated data endpoints are a Premium feature. Dedicated data endpoints enabled IPv4AndIPv6 requires dataEndpointEnabled: true ; the service rejects the setting otherwise. Azure CLI 2.87.0+ Adds --endpoint-protocol to az acr update . For geo-replicated registries, the endpoint protocol is a registry-level setting, and dedicated data endpoints exist in every replica region. Firewall guidance: rules based on registry FQDNs — the login server, dedicated data endpoints, and regional endpoints (if enabled) — continue to work unchanged for dual-stack registries; only IP-address-based allowlists need updating for IPv6. To learn more, see IPv6 dual-stack endpoints in Azure Container Registry (preview) and the ACR endpoint reference. If you have further questions about IPv6 dual-stack endpoints or dedicated data endpoints, reach out to us on the Azure Container Registry GitHub repository or file feedback through the Azure portal.259Views1like0CommentsHow Many Copies of Each Layer Does Your Container Registry Actually Need?
Authors: Payal Mahesh and Vicky Lin Azure Container Registry team: Jeanine Burke and Johnson Shi Introduction It's Monday morning. You spin up a fresh 1,000-node AKS cluster for a big training run or a fleet-wide rollout. Every node reaches for the same large container image at the same instant. What actually happens in the next ten minutes - and whether your pods reach Ready in 9 minutes or 14 - turns out to depend on a single number you've probably never thought about: how many copies of each image layer exist behind your registry. At the surface, you see a single capacity number for your registry size - but behind that abstraction, Azure Container Registry maintains copies of your layer data to optimize pull performance. That number of copies directly determines the read throughput available per layer. Each copy can serve requests independently, so distributing the layer across storage allows it to be read in parallel. More copies mean more independent readers - and higher aggregate throughput when thousands of nodes pull at once. The intuitive answer is that more is better: add copies, get faster pulls. When we actually tested it at 1,000-node scale, the truth turned out to be more interesting: A few extra copies helped a little. A moderate number helped a lot, and eliminated storage throttling entirely. A large number helped no more than the moderate one. A huge number actually made pulls slower again. Think of it like opening checkout lanes at a grocery store. Opening a few more lanes when the store is slammed cuts the line dramatically. Past a certain point, though, extra lanes barely help, because by then it's the customers, not the cashiers, who are the bottleneck. And open too many? Now the staff is spread thin and tripping over each other, and the line moves worse than it did at the sweet spot. This post walks through what we measured, why the curve bends where it does, and what we're building next so finding that sweet spot isn't something anyone has to do by hand. Key Takeaways There's a sweet spot, not a slope. Adding copies per layer cut pod-startup P99 by 27% and raised P50 per-node egress throughput by 244%, but only up to a point. Past that, the returns vanish, and far past it, latency actually regresses. Storage throttling is the real enemy. The win comes from spreading load across enough storage backends that no single backend gets pinned at its egress ceiling. Once throttling is gone, more copies stop helping. Storage scale alone has a ceiling. Even at the sweet spot, the per-backend egress limit caps total throughput. The next jump in performance has to come from somewhere else, which is exactly what we're building (see What's Next). This isn't something customers should need to manage. We're building a proactive, on-demand storage scaling capability that automatically grows the footprint before throttling happens and shrinks it back when the burst is over. A quick bit of background Within a region, the layer data behind your container images is backed by Azure storage. The number of copies ACR maintains per layer determines how many independent storage backends a concurrent-pull workload can spread its reads across. That's what matters, because each backend has a finite egress ceiling. Once concurrent reads against one backend get close to that ceiling, requests start getting throttled, and your pulls slow down in proportion. The principle is simple: more copies per layer means more backends serving the same data, which means more total egress headroom and fewer throttled requests. What we wanted data on was how many, and where it stops helping. How we tested We ran a controlled series of large-scale pull tests against ACR Premium on a roughly 1,000-node cluster, with every node pulling the same large image cold at the same time (no local cache on any node). The only thing we changed between runs was the number of per-layer copies behind a single registry endpoint. Everything else, including rate limits, the image, node count, and concurrency, stayed constant. For each run we measured pod-startup latency (P50/P90/P99), end-to-end storage read latency, egress throughput distributions (P50-P99.9), and storage throttling events. Pod-startup latency is our headline metric, because it's the one number that reflects the actual customer experience no matter where the bottleneck happens to be. Per-node egress throughput matters too, though. It tells you directly how much pull bandwidth ACR delivers to your fleet, and it's usually what customers have in mind when they ask how much faster extra copies will make their pulls. We report egress as a distribution rather than a single average, since per-request and per-time-window views can tell very different stories about the same set of pulls. These are observations from a single controlled environment, not a service guarantee. Absolute numbers will move with image size, node count, layer composition, network topology, and concurrency. What we found We tested five configurations, sweeping from a low baseline number of per-layer copies up to a very high one. We name them by relative copy count rather than exact instance counts: Baseline: the lowest level, our reference point. Low: a modest step up from Baseline. Mid: a meaningful step up from Low. Higher: a further step up from Mid. Very high: the largest configuration we tested, well above Higher. Here are the numbers. All percent changes are relative to Baseline. Configuration Pod startup P50 Pod startup P90 Pod startup P99 Storage throttling events Peak per-backend egress Baseline (fewest copies) 9m 36s 11m 0s 14m 16s Many; all top backends above the egress ceiling Highest Low 9m 27s (−2%) 10m 14s (−7%) 12m 59s (−9%) Some; one backend still above the ceiling High Mid 9m 25s (−2%) 9m 45s (−11%) 10m 22s (−27%) Zero Below the ceiling Higher 9m 20s (−3%) 9m 37s (−13%) 10m 22s (−27%) Zero Well below the ceiling Very high 9m 28s (−1%) 10m 31s (−4%) 13m 48s (−3%) Zero Lowest Look at the P99 pod-startup column from top to bottom: 14m 16s, 12m 59s, 10m 22s, 10m 22s, 13m 48s. It improves, flattens out, then climbs back up. Three things explain that shape: 1. The win: Throttling falls off a cliff at the Mid configuration As we added copies per layer, per-backend egress fell and storage-side throttling decreased. At the Mid configuration, throttling errors hit zero, and they stayed at zero for every configuration above it. The upside isn't just that the errors went away, though. It's raw pull bandwidth. At the Mid sweet spot, the typical node saw its P50 egress throughput jump 244% over Baseline. With load spread across enough copies, each node pulled its layers off storage much faster, not just without stalling. For a workload owner, that's the difference between watching pods come up in a steady stream and watching them stall for tens of seconds at a time while throttling clears. Same image, same node count, same registry, very different experience. To put it in concrete terms: if your team runs a daily AI training kickoff that needs all 1,000 nodes pulling before the job can start, this is the difference between starting on time and starting four minutes late every day. Over a quarter of training runs, that adds up. 2. The surprise: more copies made pulls slower This is the finding that genuinely surprised us. Going from Higher to Very high, the largest configuration we tested, cost us 3 minutes and 26 seconds at P99: 10m 22s climbing back up to 13m 48s. That gave back almost the entire benefit we'd built up over the previous four configurations. Tail storage-read latency at Very high actually came out worse than Baseline. The Very high run is where the wheels came off, and the reason is the trade-off underneath. Once storage throttling is gone, more copies stop buying you anything, and the cost of fanning reads across that many backends starts to take over. The throughput distribution shows it clearly. P50 and P75 throughput had been climbing steadily and getting smoother through Mid and Higher, then dropped sharply at Very high while the peak P99/P99.9 spikes came back. Spread the same load across too many backends and it fragments into smaller, less consistent bursts. The takeaway is that "more is better" stops being true past the sweet spot, and the failure mode is quiet. You won't see throttling errors. You'll just see your pulls get slower. 3. What we didn't expect: at few copies, the hottest backend is what hurts you At the lowest copy counts, pull traffic wasn't spread evenly across the underlying storage footprint. Some backends absorbed far more traffic than others. As we added copies, that distribution evened out and the hottest backends cooled down. The implication is sharp. You can saturate the busiest backend, and trigger throttling, even when the total headroom across all your backends is large in aggregate. What matters is the load on the hottest backend, not the average. That's exactly the failure mode that demand-driven, proactive scaling (described below) is meant to head off before it happens. So how should you think about this? You don't size copies yourself; ACR manages the storage footprint behind your registry. Still, it helps to understand what moves the sweet spot, because the shape of your own workload is what decides where it lands. The bigger your worst-case concurrent burst (more nodes, larger images, higher concurrency), the more copies per layer it takes to keep pulls off the throttling ceiling, and the further out the sweet spot sits. Smaller workloads may already be sitting on the flat part of the curve. One thing is worth saying plainly. The storage footprint underneath is managed by ACR and shared across many registries, so there's no fixed, private storage budget that maps one-to-one to your workload. The sweet spot isn't a number you compute and provision; it's a behavior the platform has to land on for you, which is exactly why we're moving toward demand-driven scaling that handles it automatically. That's what brings us to what we're building next. What's next: proactive, on-demand storage scaling and a caching layer The fixed-copy tests above answer the question "how many should the ACR system provision?" but they assume a single, static answer. Real workloads aren't static. A 1,000-node burst happens at deploy time, not at 3 a.m. on a Tuesday. And no matter how many copies are provisioned, the per-backend storage ceiling still bounds peak deliverable throughput. So we're investing along two complementary directions. 1. Proactive, demand-driven storage scaling We're building a capability that adjusts the number of per-layer copies automatically based on real-time pull demand: Proactive, not reactive. The system scales the storage footprint before concurrent pull pressure pushes any single backend near the throttling threshold, so throttling is prevented before it forms rather than cleaned up after the fact. On-demand scale-out. The footprint expands automatically as sustained pull demand grows. Scale-in when demand subsides. The footprint contracts so you're not paying for steady-state capacity you only needed during a burst. Tiering for cold content. Long-tail, rarely-pulled content can sit on colder storage, so the redundant footprint of frequently-pulled content doesn't pay full hot-storage cost everywhere. The benefit to customers is straightforward: smoother pulls under burst, higher delivered throughput on average, no permanent over-provisioning, and no manual re-tuning as workloads grow. 2. A caching layer to absorb burst beyond the storage ceiling Even a perfectly scaled storage footprint runs into the per-backend egress ceiling at extreme scale. To push past it, we're investing in a caching layer in the registry service that absorbs burst traffic before it ever reaches storage. A pull surge that hits the same set of layers, which is the common case for fleet-wide deployments, can be served largely from cache. That takes a lot of load off any single storage backend and complements the storage scaling above. We'll share results from this work in follow-up posts. If you have questions about scaling ACR for your workload, or about how we measure storage performance, reach out on the Azure Container Registry GitHub repository. Note: All results in this post are based on controlled internal testing configurations and are intended to illustrate general scaling behavior rather than prescribe exact configurations.288Views0likes0CommentsTutorial:A graceful process to develop and deploy Docker Containers to Azure with Visual Studio Code
Creating and deploying Docker containers to Azure resources manually can be a complicated and time-consuming process. This tutorial outlines a graceful process for developing and deploying a Linux Docker container on your Windows PC, making it easy to deploy to Azure resources. This tutorial emphasizes using the user interface to complete most of the steps, making the process more reliable and understandable. While there are a few steps that require the use of command lines, the majority of tasks can be completed using the UI. This focus on the UI is what makes the process graceful and user-friendly. In this tutorial, we will use a Python Flask application as an example, but the steps should be similar for other languages such as Node.js. Prerequisites: Before you begin, you'll need to have the following prerequisites set up: WSL 2 installation WSL provides a great way to develop your Linux application on a Windows machine, without worrying about compatibility issues when running in a Linux environment. We recommend installing WSL 2 as it has better support with Docker. To install WSL 2, open PowerShell or Windows Command Prompt in administrator mode, enter below command: wsl --install And then restart your machine. You'll also need to install the WSL extension in your Visual Studio Code. Python 3 installation Run “wsl” in your command prompt. Then run following commands to install python 3.10 (if you use Python 3.5 or a lower version, you may need to install venv by yourself): sudo apt-get update sudo apt-get upgrade sudo apt install python3.10 Docker for Linux You'll need to install Docker in your Linux environment. For Ubuntu, please refer to below official documentation: https://docs.docker.com/engine/install/ubuntu/ Docker for Windows To create an image for your application in WSL, you'll need Docker Desktop for Windows. Download the installer from below Docker website and run the downloaded file to install it. https://www.docker.com/products/docker-desktop/ Steps for Developing and Deployment 1. Connect Visual Studio Code to WSL To develop your project in Visual Studio Code in WSL, you need to click the bottom left blue button: Then select “Connect to WSL” or “Connect to WSL using Distro”: 2. Install some extensions for Visual Studio Code Below two extensions have to be installed after you connect Visual Studio Code to WSL. The Docker extension can help you create Dockerfile automatically and highlight the syntax of Dockerfile. Please search and install via Visual Studio Code Extension. To deploy your container to Azure in Visual Studio Code, you also need to have Azure Tools installed. 3. Create your project folder Click "Terminal" in menu, and click "New Terminal": Then you should see a terminal for your WSL. I use a quick simple Flask application here for example, so I run below command to clone its git project: git clone https://github.com/Azure-Samples/msdocs-python-flask-webapp-quickstart 4. Python Environment setup (optional) After you install Python 3 and create project folder. It is recommended to create your own project python environment. It makes your runtime and modules easy to be managed. To setup your Python Environment in your project, you need to run below commands in the terminal: cd msdocs-python-flask-webapp-quickstart python3 -m venv .venv Then after you open the folder, you will be able to see some folders are created in your project: Then if you open the app.py file, you can see it used the newly created python environment as your python environment: If you open a new terminal, you also find the prompt shows that you are now in new python environment as well: Then run below command to install the modules required in the requirement.txt: pip install -r requirements.txt 5. Generate a Dockerfile for your application To create a docker image, you need to have a Dockerfile for your application. You can use Docker extension to create the Dockerfile for you automatically. To do this, enter ctrl+shift+P and search "Dockerfile" in your Visual Studio Code. Then select “Docker: Add Docker Files to Workspace” You will be required to select your programming languages and framework(It also supports other language such as node.js, java, node). I select “Python Flask”. Firstly, you will be asked to select the entry point file. I select app.py for my project. Secondly, you will be asked the port your application listens on. I select 80. Finally, you will be asked if Docker Compose file is included. I select no as it is not multi-container. A Dockefile like below is generated: Note: If you do not have requirements.txt file in the project, the Docker extension will create one for you. However, it DOES NOT contain all the modules you installed for this project. Therefore, it is recommended to have the requirements.txt file before you create the Dockerfile. You can run below command in the terminal to create the requirements.txt file: pip freeze > requirements.txt After the file is generated, please add “gunicorn” in the requirements.txt if there is no "gunicorn" as the Dockerfile use it to launch your application for Flask application. Please review the Dockerfile it generated and see if there is anything need to modify. You will also find there is a .dockerignore file is generated too. It contains the file and the folder to be excluded from the image. Please also check it too see if it meets your requirement. 6. Build the Docker Image You can use the Docker command line to build image. However, you can also right-click anywhere in the Dockefile and select build image to build the image: Please make sure that you have Docker Desktop running in your Windows. Then you should be able to see the docker image with the name of the project and tag as "latest" in the Docker extension. 7. Push the Image to Azure Container Registry Click "Run" for the Docker image you created and check if it works as you expected. Then, you can push it to the Azure Container Registry (ACR). Click "Push" and select "Azure". You may need to create a new registry if there isn't one. Answer the questions that Visual Studio Code asks you, such as subscription and ACR name, and then push the image to the ACR. 8. Deploy the image to Azure Resources Follow the instructions in the following documents to deploy the image to the corresponding Azure resource: Azure App Service or Azure Container App: Deploy a containerized app to Azure (visualstudio.com) Opens in new window or tab Container Instance: Deploy container image from Azure Container Registry using a service principal - Azure Container Instances | Microsoft Learn Opens in new window or tab6.9KViews4likes1Comment
