Overriding Default Commands
If you want to override a container's default command, you can do so with -command. For example, suppose the docker/whalesay image runs command /bin/bash by default:
# icm docker -command "ps -a"
CONTAINER ID IMAGE COMMAND CREATED STATUS NAMES
17f4ece54c2f docker/whalesay "/bin/bash" 4 days ago Restarting gracie
To have the container run a different command, such as pwd, you could deploy it as follows:
# icm run -container gracie -image docker/whalesay command pwd
You can verify that the command succeeded by examining the Docker logs:
# icm docker -command "logs gracie"
/cowsay
