Upgrading old version 2.8.5 issues

Support
, ,
1

It just so happens that we haven’t updated Discourse in a very long time. We’re currently at v2.8.5. I recently discovered that Discourse is well beyond version 3.
I’d like to update to the current version, but for now, I’d like to at least update to the latest version 2.8.x - 2.8.14.
And here’s a huge problem. When I rebuild, Discourse updates the base image, and I get this error:

./discourse-doctor may help diagnose the problem.

The plugins are all clear - they need to be commented out in app.yaml. But that doesn’t help - the plugin errors disappear, and the error:

The "discourse" Nginx outlet is missing. This version of discourse_docker is not compatible with the chosen Discourse version

remains.

And I can’t do anything about it. Is there any way to update my forum to version 2.8.14?

If not, and for the future, how can I upgrade from version 2.8.5 to version 3.x.x? The situation is complicated by the fact that I use an external database, PosgreSQL. As I understand it, due to the AI ​​features in the new Discourse, it requires a vector database, PgVector. Do I need to migrate somehow? Is there a guide on how to do this correctly and painlessly?

I’d really appreciate your help!

Try updating Docker, does that help?

I removed all plugins from app.yaml. This didn’t help:

Please share your app.yml file, sans passwords.

It appears plugins are not the cause of the rebuild failure, the issue lies here.

Could you please provide the preceding context from the logs? Perhaps the actual error occurred there.

It’s a good bet that your OS it out of date too. The easiest and safest thing to do is move to a new vm with an up-to-date OS and docker.

9

Here’s the original app.yml. I obfuscated it a bit. It has all the plugins. For testing, I removed them all, but rebuilding still produces an error.

app.yml (4.9 KB)

10

Ubuntu 20.04 is still fine, and has all the latest packages.
Docker Engine 28.1.1 is also quite up-to-date.

And why migrate to another VM if I can update this one in-place?

11

See my above quote from the logs.

Because the postgres upgrade can be problematic and installing on a new VM assures that you can’t end up with a broken forum.

But wait. Do you have this line in your app.yml?

version: v2.8.10 ## CHANGED FROM stable (v2.8.5) TO v2.8.10 FOR UPDATE

That’s not going to work because the current docker container won’t work with that old of a Discourse. You need to upgrade to the latest version, or at least the latest supported version. It’s possible if you switch to a more recent version you won’t get that Docker error.

Also, Discourse no longer works without https, so you need to un-comment the ssl and letsencrypt templates. And some other stuff has changed too. I’d recommend that you do a full reinstall with discourse-setup to get an up-to-date app.yml as well.

12

PostgreSQL is installed separately in Docker, and updating it is no problem.

Is this absolutely necessary? I don’t want to upgrade to version 3.x.x yet—all the AI ​​features in it require migrating from PostgreSQL to PgVector. We don’t really need AI on the forum, and I’m not familiar with PgVector at all, so I don’t know how to migrate like that. So, for now, I’d prefer to stay on the most recent version 2.8.x—2.8.14, if possible.
If that’s not possible, then of course I’ll have to migrate. In my first message, I asked if there was a guide for such a migration?

But I don’t want to use Discourse’s HTTPS and letsencrypt. My forum is behind Nginx, which is configured according to our perimeter rules. I’d like to keep this setup.

Thank you so much for your help! I look forward to your comments.

I’ve pointed to several. I’m afraid none applies to your setup. You’ll have to upgrade postgres. You’ll have to install pgvector.

Then it’ll be a bit more complicated than I described since you’re pretty far from a standard install.

If you’ve got a budget you can ask in Marketplace or contact me directly.

The most recent version is Discourse 3.6.0.beta3-latest. While nothing is impossible, if you want to stay on 2.8.x then you may as well just do nothing. It’s not supported and has serious security issues.
