Docker-Manager Version: v0.2.0

Docker image that manages other dockers in stadalone mode.

It is created as a service in swarm and runs and controls N dockers configured in docker-manager.cfg in standalone mode. So if the docker host drops or the service migrates for some reason, dockers managed by docker-manager are disconnected and started on the new host that the service is instantiated.

Available from docker hub as riav/docker-manager

Usage

docker service create --name test-01 --replicas 1 \
                    --mount type=bind,source=/var/run/docker.sock,destination=/var/run/docker.sock \
                    --mount type=bind,source=/logs-test-01,destination=/var/log/docker-manager \
                    --mount type=bind,source=/docker-manager.cfg,destination=/docker-manager.cfg \
                    --restart-condition any riav/docker-manager

For testing and development with docker api

docker run -d -v /var/run/docker.sock:/var/run/docker.sock riav/docker-manager --mode-run
