It can be simplified by using Docker Compose to start your containers instead of the plain docker run command. Docker restart policies are applied on a per-container basis. This is extremely helpful in scenarios where you have to restart the Docker host (your Linux server) or if the service running in the container fails. The result is a convoluted manual replacement process. Docker provides a restart policy option to let your containers restart automatically in case of certain events or failures. Here is a small sample docker-compose. Start a new container docker run -d -p 80 :80 -name example-nginx nginx:latest Docker lacks a built-in way to detect image updates and replace your running containers. If you expose port 80 on all your containers with webapplications you could link to them to your Nginx container. Ideally, I would like a solution that would not be distro specific, such as using supervisord rather than writing an upstart or systemd startup script, but I need a way to hook into triggering after the docker daemon has finished starting successfully. Open the docker event in one shell and run the container with always policy with another shell. I can use the docker run paramater -restart=always to have all of my running containers start up automatically after a reboot, however, how can I ensure that my reverse proxy container starts first before anything else, and there is a short delay before any of the other containers are started (in any order). Often I need to reboot my servers and I need a solution that will start all my containers automatically and in the right order. The next command removes all containers, which is docker remove (docker ps -a -q). v /var/run/docker.sock:/tmp/docker.sock \ To stop all of your running Docker containers, issue the command docker stop (docker ps -a -q). Use the command line to log in to NGC before pulling the Isaac Sim container. nvidia-smi Get access to the Isaac Sim Container using your NVIDIA Developer Program credentials. Run the command below to confirm your GPU driver version. RESULT=`docker ps | grep jwilder | wc -l` Steps: Setup and install the container prerequisites. # which allows us to run multiple web containers Also you can restart an existing Docker container by specifying its container ID, i.e.: docker start However I can't determine if it's possible to change an existing container, that originally was not run with the -restart'always' option, to convert it to always restart in future.# ensure that we are running the frontend proxy This requires the jwilder/nginx-proxy to be running before the container has started, which is easy enough in the bash script I run to start the container after it has been built. To allow them to all run on a single host, I allow docker to assign a random unused port, and use the jwilder/nginx-proxy ( reference) as a reverse proxy. to run a command within an existing container: /5 docker exec exampleappcontainer /example-scheduled-task.sh This will only work if you can be sure of the container's name ahead of time. Almost all of my docker containers are web applications that run on port 80. The docker start command is used to start a stopped container, and the docker restart command is used to restart a running container.
