I am trying to setup discourse for my organisation on k8s. However there are few issues I am facing. When I try to deploy the bootstrapped image on kubernetes it tries to do stuff like git pull pups and git pull discourse which doesnt work since I am on a private network without any access to the …

[图片] Divyaanand_Sinha: When I try to deploy the bootstrapped image on kubernetes it tries to do stuff like git pull pups and git pull discourse which doesnt work Are you sure you are deploying an already bootstrapped image? Sounds like you pushed the wrong image to your registry.

Oh is it, I am using the image created by ./launcher bootstrap app So you are saying that the final bootstrapped image shouldn’t be having any such dependencies?

[图片] Divyaanand_Sinha: So you are saying that the final bootstrapped image shouldn’t be having any such dependencies? No it won’t. After bootstrapping, there will be a local_discourse/app image. That is the one that you need to push to the registry and use elsewhere.

One final doubt, so it seems i was pushing the wrong image, my bad. So after i push the actual image I can change the env variables during k8s deployment right? Like DISCOURSE_DB_HOST etc? Because I have a separate postgres cluster and redis cluster!

So i already have an instance of discourse running but thats on bare metal, i want to move it to k8s, and connect to the same db the bare metal one was using.

Or if possible can I do the bootstrap again with the DISCOURSE_DB_HOST and DISCOURSE_DB_NAME pointing to the same db the bare metal one is using?

That should work! You may want to stop the current Discourse container that is connected to the DB while doing that, because migrations may make it behave in a broken way.

If I create a fresh new empty db and bootstrap using that, then is it possible for me to migrate the data from the UI instead (using the UI of the old discourse instance and the new discourse instance) like /admin/backups? I want to avoid corrupting the old DB , its being used by a lot of users.

You can’t migrate from the ux. See Introducing Post Deployment Migration . This allows you to migrate the database such that it works for both the old and new container, then do final migrations after you deploy.

您无法从 UX 进行迁移。

请参阅介绍部署后迁移。这允许您迁移数据库，使其同时适用于旧容器和新容器，然后在部署后执行最终迁移。
