Can't start beginner tutorial: 'docker - command not found'

[ursusprimus]

I just installed Grafana on a Raspi4 and wanted to start with the tutorial as described here: Grafana fundamentals | Grafana Labs
But I’m stuck at step 3 already: Docker not found:

Could anyone tell me what to do, please?

[melrose]

ok, and have you installed docker?

This makes sense, I’m just installing it.
Stupid in retrospect, but i’m new to linux and haven’t even thought about it.
So soon I should be able to continue with the tutorial, thanks

My next problem is: the sample application doesn’t work. I followed the first 5 steps up to here:

I think the two lines should show UP instead of EXIT:
tutorial-environment_app_1 /bin/sh -c /app http://db … Exit 2
tutorial-environment_db_1 /db Exit 1

In any way, when I try to access the sample application via pi-IP-adress:8081 the page is not available.

Same problem here also in a Raspberry Pi 4 with Rapsbian 10 (buster)
