Brand new user, everything working but some doubts about HA OS internals

Installation Home Assistant OS
1

Hi, new user adding more and more zigbee sensors into my installation. My experience has been really smooth, everything working at first try, probably because I am an advanced linux user.

I have one questions just to deepen my understanding of HA OS related to docker working presumably under the hood. I understood HA OS is using containers technology, however in the terminal and as a root user, I can not find the docker command (command not found), and I can not see a running docker process either (ps command in the terminal).

However as an answer of ha info command I can see docker version 26.1.4 (3rd line) installed?

Does HA OS really uses docker?, Can i have access to the list of running containers?, I have already installed integrations and add-ons.

HA OS is a minimal linux OS built on buildroot with just one job: running a bunch of docker containers.

If you want to see the docker command: add a monitor and keyboard to your HA computer, and in the console enter

login

(no password). Then you can access the docker command.

The 2 ssh add-ons are just docker containers themselves.

The “Advanced SSH & Web Terminal” addon should give access to and list containers.
I have protection mode disabled and that might be necessary though.

Thank you for your answers, I have just realized how different is the admin of a containerized Linux OS than a regular Linux.

I can see that there is many question in relation of how to access the host system from the container environment, for example:
