Doing your course on Pluralsight. Love the course, BTW!

Tried running the docker compose version of Jenkins:

mark@linuxmint:compose$ pwd
/home/mark/workspace/github.com/g0t4/course-jenkins-getting-started/dockers/compose
mark@linuxmint:compose$ git status
On branch master
Your branch is up to date with 'origin/master'.

nothing to commit, working tree clean
mark@linuxmint:compose$ git pull
Already up to date.

ERROR: Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

I thought I had the latest docker installed.

What am I missing?

Try to change the version within the docker-compose.yml from 3.8 to 3.7.

Still same error.
