Error during install: ops/bin/buildfs.sh: line 28: docker: command not found

When I run the local-up.sh script I get an error that Docker cannot be found. It looks like Docker is missing in the agent image:

Environment

• Hocus version: 5ca804d388423a4a959a2549572d2ba29a4c0203
• Host OS is Ubuntu 22.04 with latest updates

Docker is installed on the host, but I see this error is coming from the agent container with is Ubuntu 20. I added the following to buildfs.sh for additional debug output:

cat /etc/os-release
echo $PATH
ls -al /usr/bin | grep docker

Which yields:

+ cat /etc/os-release

That's a peculiar error. We run ops/bin/local-up.sh in CI on every commit and docker is not missing there. Once https://github.com/hocus-dev/hocus/pull/108 is merged, we will make a new release that completely removes the step that's causing this error, so that should fix the problem.

0.3-alpha fixes it, thank you!
