Docker

How it works

• a container is a process

Cheatsheet

Attaching to Container

Since I leave containers running in some cases for regular usage, I need to be able to enter and exit the container.

Attach

1
docker attach CONTAINER


Note: There is also nsenter which I should look at again.

Detach

It seems that the way to do this is ctrl+p, ctrl+q.

Building Containers

Building a container simply creates an image which can then be used to launch a specific instance of a container.

Assuming the current directory contains the Dockerfile

1
docker build -t NAME:TAG .
