Docker-Commands-Cheat-Sheet.md

+This page contains some common commands you may need to use with Docker and Freedmr. All 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
+
+    cd /etc/freedmr
+    docker-compose up -d
+
+The -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 freedmr
+
+You can replace "freedmr" with the container you wish to restart
+
+## Show running containers 
+
+    docker-compose ps 
+
+## Update containers from repository 
+
+    docker-compose pull
+
+This should be followed by a down / up sequence 
+
+## Connect to a shell inside a running container 
+
+    docker exec -it freedmr /bin/sh
+
+Note, 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.
