I vaguely remember docker compose is coming to TrueNAS SCALE. What's the rough timeline for that?

[Stux]

I have as video which covers sandboxes fairly well.

TrueNAS Scale: Setting up Sandboxes with Jailmaker

In Electric Eel you won’t need the sandbox to run docker (and compose). Additionally the apps will be made using compose too.

And dockge is installable as an app.

I cover this in a different video
