AWS installation stuck in Read only mode

Thanks.

So to build a specific version of Discourse, all I’ll need to do is specify a commit hash as the version value?

Example of web.template.yml:

params:
  # Building from branch "stable" with latest commit
  version: 849b4b56853756a24f0646c04e733e5af7cc2a2b

This will then be picked up by:

- git fetch origin $version
        - git checkout $version

Is this correct?
