I've been trying to get two containers of a single image started up, however when I am unable to attach to the second container.

Here's what I've got so far.

[]#docker image ls

gives me the one image I have, docker.io/centos

[]#docker container ls -a

Shows my first container, with the proper image name, status exited, command of "/bin/bash"

I can start this container fine with []#docker container start -ai container0 This opens it on my console and everything is peachy.

The problem starts when I create another container with the same image.

[]#docker container create docker.io/centos
bc342cb83cc1284e594c3f5ee[etc...]
[]#docker container start -ai bc342cb83
[]#

It just goes back to the normal console. Starting container0 still works normally.

[]#docker container start -ai container0
;@container0:/[root@container0 /]#

I don't think you're doing it right...

  • yeah... I'm in the process of writing my containers to images and doing pretty much your example. Once it's done I'll come back and delete this question since it's just me not using docker the right way. – UpTide Jul 11 '18 at 15:19

    honestly i figured i would lose at least 3 rep on this question, so i guess it's more helpful than i thought – UpTide Jul 11 '18 at 16:01
