Docker command reference

Various Docker commands are supported in the development environment.

The following table describes the supported commands:

Table 1. Docker command reference
Command	Description
`docker images`	To see all your images. You will see at least four images corresponding to application server, Db2 server, MQ server, and OMS runtime.
`docker ps`	To see all running containers. You will see at least four active containers corresponding to application server, Db2 server, MQ server, and Sterling™ Order Management System Software runtime.
`docker logs -f –tail 100 <container_name>`	To see the running logs of the given container starting with the last 100 lines.
`docker exec -it <container_name> bash`	To enter an active container as a root user. Note: Be careful while you run commands inside a container. Running unverified commands can make your container unusable and you may have to do fresh setup again.
`docker start <container_name>`	It is recommended to use the commands in Docker Compose command arguments to start, stop or restart one or all services rather than directly using the docker commands. Note: You must not use the `docker start/restart om-appserver` as it does not deploy your applications correctly. Instead, you must use  the `./om-compose.sh restart appserver` command.
`sudo systemctl start docker`	To start the Docker daemon.
`sudo service docker status`	To check whether Docker is running.
