Concepts

Namespaces: what the virtualization software can see. We set these up with syscalls. Restricts the view of the stuff on the virtualization.

Tricks

sudo docker run --rm -it ubuntu /bin/bash -> run docker with ubuntu, then activate shell
sudo docker ps -> list all docker running processes
docker build -t [name]:[latest] . -> build your dockerfile
ducker run -it [name]:[latest] -> run your docker stuff interactively
docker image -> look at docker images around
docker exec -it [container] sh -> open shell inside a container
docker inspect <container name> -> inspect some shit
docker container stats -> look at stats
