DockerでDiscourseの特定バージョンをデプロイする

[DjangoElBongo]

@maaatt

deploy one specific version of the software?

I think you will find the answer in the following post:

How would I install a certain (old) version of Discourse

Checkout the same version of discourse_docker that you use on your other server, maybe copy your app.yml from the old server and make the necessary changes. Also in app.yml, change the version from tests-passed to either a tag (e.g. v2.5.0.beta7) or use a git commit hash.
