Nextcloud docs - nextcloud and database

charm
,
1

The absolute minimum of a nextcloud installation is nextcloud itself and a database.

Create a new model and deploy nextcloud and a database:

juju add-model my-nextcloud
juju model-config default-series=jammy
juju deploy postgresql
juju deploy nextcloud 
juju integrate postgresql nextcloud:database

... wait for deployment to settle.
Then, visit http://<yourip>

To get the admin password:

juju run-action nextcloud/0 get-admin-password --wait

Make sure to note it and change it after first login, since this action will only work once.

Next steps:

You can expand the deployment with haproxy (to provide ssl), redis (for cache) and possibly a persistent or shared storage.

Hi @erik-lonroth!

I was trying to deploy the nextcloud charm using those instructions, but couldn’t manage to make it work.

I changed the deploy commands a little bit (due to the changes in the PG charm channels and that the nextcloud charm is available only on the edge channel):

juju add-model my-nextcloud
juju model-config default-series=focal
juju deploy postgresql --channel latest/stable
juju deploy nextcloud --channel latest/edge
juju relate nextcloud:db postgresql:db

The error that I received was the following:

unit-nextcloud-0: 13:05:24 ERROR unit.nextcloud/0.juju-log Uncaught exception while in charm         code:

Do you have any idea about how to solve that?

Oh, I think this is a bug. Would you mind placing an issue? I’ve seen it before and I think its an easy fix

What you can do to patch this is to add the key “manually” in charm.py and then remove it once its been deployed.

Sure. I created https://github.com/erik78se/nextcloud-charms/issues/61.

Thanks for the hint. I’m gonna try to patch it. Thanks @erik-lonroth!

@neppel - I’m working on refactoring the Nextcloud charm to use the new charm lib and make the charm alot easier.

Here is the PR I’m working on: https://github.com/nextcloud-charmers/nextcloud-charms/pull/78

If you like to help, just let me know and I’ll also add you to the github repo.

There is some work needed to get the charm more stable and remove some unused code etc. Any help on the charm is welcome.

I’ll help you resolve the issue you have if you run into more problems and I can also show you how to integrate with needed charms - redis and haproxy which can be somewhat tricky.

Just let me know.

@joakimnyman is also adding to the work here.

Hi @erik-lonroth

As I can see the manual refers to the legacy interface:

juju relate nextcloud:db postgresql:db

but the charm ships the modern interface requirements.

Should the documentation be updated to:

juju relate nextcloud:db postgresql

Or even:

juju relate nextcloud postgresql

Thank you!

Thanx for pointing this out. I’m currently testing a new version of the charm and I have updated the documentation to reflect your comments. Thanx for this!

The latest version of the charm should work with nextcloud 29 which to date is the latest stable.

UPDATE: A new edge on revision 26 now out, feel free to test it

Revision 26 of ‘nextcloud’ released to edge
