Launch a container with Docker without specifying command

docker, lxc

Solution

With docker, from the CLI, you can't create a container without running a command on it. If you want to use the REST Api, you can call the 'create' endpoint without 'start'.

However, it wouldn't be any good for you I think.

In most case, you probably just want to run a container with bash `docker run -t -i ubuntu bash` and do stuff there. Once you did everything you needed, you can simply commit and run from this point.

Usually however, it is better to do one step at a time in order to keep a clear history. Take a look at the Docker builder :)

Problem

I'm familiar with LXC and wanted to try out docker. The issue I'm facing is that I can't find a way to just tell docker to start a container in the background, without executing a command. For example, with LXC I would do : `lxc create -t ubuntu -n my_container` `lxc-start -n my_container -d` At this point I would have a running container I can use as any VM (ssh to it, install stuff in it ...) It seems that docker prevent this kind of usage. Am I missing something ?
