Thoughts on attaching to Docker Container:
Especially useful for Turnkey Linux docker containers. In some cases you need to exit the fence to continue to boot. Then ssh back in with root to set the password. When you attach like this – you can more or less think of this as the master console of the container.
When first bootstrapping a Turnkey Linux Container – you need to get in to setup.
to attach.
docker attach <name>
To detach
Do not press control-C – that will exit the container.
<CTRL-P> <CTRL-Q> – you will see “read escape sequence” – that means you did it!!!
