This page contains some common commands you may need to use with Docker and FreeDMR. Most of these commands should be run from /etc/freedmr. Where the container name "freedmr" has been used, you can replace this with any other container name.
Create and start containers
docker-compose up -dThe -d flag stands for Daemon. If you want to run in the foreground, omit this.
Stop and remove containers
docker-compose down Start / Stop / Restart a container
You will need to do thi after changing the freedmr config, for example
docker-compose start freedmr
docker compose stop freedmr
docker-compose restart freedmrYou can replace "freedmr" with the container you wish to restart
Show running containers
docker-compose ps Update containers from repository
docker-compose pullThis should be followed by a down / up sequence
Show logs
docker-compose logs [-f] [--tail 300] freedmrthe -f and --tail are optional.
-f is follow - like tail -f --tail N shows the last N lines
Connect to a shell inside a running container
docker exec -it freedmr /bin/shNote, you probably don't want to do this unless you are heavily debugging. Remeber a docker container is a minimal install and doesn't have many tools inside. Also, most of the freedmr containers are read-only, so you can't change anything.
Clean system of various things
docker network prune
docker container prune
docker image prune Run docker compose commands on another machine, remotely without logging in.
export DOCKER_HOST=“ssh://user@remotehost”
then you can use docker-compose commands locally, as if you were logged in to that server. You need to have the docker-compose.yml file locally to do this.
