Help deploying older versions of Discourse

The root cause is that the git symbolic-ref --short HEAD command can only return the branch name.

We use this command inside an if [[ ]] statement to check whether the supplied ref is the same as the current branch. For tags and non-latest branches, it is expected to fail, so then we hit the ‘else’ branch of the if statement.

That will run a git checkout ..., which does work with tags.

Latest summary: If you only want to deploy the latest Long-Term Support (LTS) version, simply modify containers/app.yml:

# Add the following configuration at the end
params:
  version: esr

Then rebuild

Great, glad to hear you got it working!
