MicrosoftWe are running Logic Apps in Docker containers in our Kubernetes environment (using the NodeJS version, doing development in VS Code), and it works great; has full access to your on-premise resources, if you have an on-premise Kubernetes environment this is a no-cost (or minimal) approach to deploying your Logic Apps.
I created the following shell script that I use inside the Docker container to inspect the worfklow runs/logs (generates a menu based system using Linux "dialog" and JQ for JSON formatting/parsing). This is the one thing that I was struggling with was inspecting the logs of the runs when they failed, and this 100% solves it as you can use it in a console window in the Kubernetes Dashboards in your browser:
