"docker container run" - Create Container with New Command

Q

How to Create a new Container with a New Command using the "docker container run" command?

✍: FYIcenter.com

A

If you want to create an Alpine container that starts with a new command different than the default command, you need to use the "docker container run" command with your Linux command specified.

1. Create a new container with "alpine" image and start it with "ping google.com" running in the container.

fyicenter$ docker container run --name 2nd_alpine alpine ping google.com

PING google.com (172.217.7.174): 56 data bytes
64 bytes from 172.217.7.174: seq=0 ttl=49 time=1.941 ms

2. Check the container status.

fyicenter$ docker container list --latest

CONTAINER ID  IMAGE   COMMAND            CREATED             STATUS                    NAMES
fddc7452d4f6  alpine  "ping google.com"  About a minute ago  Exited (0) 5 seconds ago  2nd_alpine

As you can see, the new container was started with the "ping google.com" command. Its console is attached to my hosting console. That's why I can see the "ping" output.

You can press Ctrl-C to terminate the "ping" command. But that also ends the execution of the container.

But the console output of the container execution is still maintained in the container. You can fetch it with the "docker container logs" command.
