![]() ![]() Note that there may be edge cases, so depending upon the situation, you may want to add additional logic to the recipe file to check for errant processes or running containers just like you would if do this directly from a shell script. Note that I want to forward the containers 8080 port to my hosts 8080, since 80 is occupied by nginx on my host. Using either approach will ensure that only one instance of the container is running. To create the docker container I run the following command: docker run -d -name rancher-server -p 8080:8080 rancher/server. You can try with the hello-world to see the difference. To confirm the successful pull/update of the image, you should see a pull event before the start event near the time you restarted, like the following: Share. Compose does not support deploy configuration - use docker stack deploy to deploy to a swarm. Restart one or more containers Usage docker restart OPTIONS CONTAINER CONTAINER. on-failure will issue a restart if the exit code indicated a failure, whereas unless-stopped behaves like always and will keep an instance running unless the container is stopped. az container restart -name -resource-group .![]() ![]() There are three restart policies: on-failure always unless-stopped on failure: It. then when Greengrass stops the component, the Shutdown lifecycle would have a docker stop my_container_name which will complete the shutdown. Or use the following Azure CLI command if the container is on a running state. To enable self-healing in a docker container, we can use restart policies in docker. In this case, you can change your docker run to name the container and run in detached (background) mode. TL DR: There has been a shift from defining complex restart policies in docker/docker-compose superseded by explicitly checking for dependencies from within your service so it is deployment agnostic. docker container restart, Restart one or more containers docker container rm, Remove one or more containers docker container run, Run a command in a new. If the container cannot process the SIGTERM, the other way to mange is to use the Startup and Shutdown lifecycles within the recipe file. If the container can process the signal and exit gracefully, this will work. In this case, the docker run command receives the signal. Essentially Greengrass is sending a SIGTERM to the process running in the 'Run' portion of the lifecycle when stopping. You can restart the component and have it restart the container. ![]()
