Caddy + Nextcloud (fpm) + Collabora - individual containers and docker-compose

Help
31

@francislavoie looks like I’ve finally managed to get EVERYTHING working locally.

Through Nginx only using HTTP for everything, with ports 80 and 9980 exposed on the host.

With our beloved Caddy, through HTTPS with a local certificate and only ports 80 and 443 exposed on the host (later I’ll do it on the VPS, with a valid certificate).

I intend to make a good documentation to add to the Wiki, for now I leave here only the necessary files/commands to reproduce locally what I did here. Just change domain/host/users/passwords to your liking.

Another important warning: always try to test on more than one distribution. I like using Arch, I learn a lot and I like its “lean” way. But there have been two or three situations where things didn’t work as they should on Arch and with the same files/settings it worked on another distribution (in this case, Ubuntu 22.04 but it could have been any other).

I begin with ~/docker/nextcloud$ docker-compose down -v to be assured that I will start from scratch. Then,

~/docker/nextcloud$ clear ; docker-compose up -d ; docker logs -f nextcloud-app

Wait till

Initializing finished
[08-May-2022 20:40:16] NOTICE: fpm is running, pid 1
[08-May-2022 20:40:16] NOTICE: ready to handle connections

Then CTRL-C and

~/docker/nextcloud$ sudo vi /var/lib/docker/volumes/nextcloud_nextcloud-app/_data/config/config.php

Add these lines

  'trusted_proxies' =>
  array (
    0 => 'nextcloud-web',
  ),
  'default_phone_region' => 'XX',

where 'XX' is your country code, this will fix the warning “Your installation has no default phone region set.” and also will add Caddy’s container (nextcloud-web) to the list of trusted proxies (fixing another warning/errors). I like to add just bellow 'trusted_domains', at line 44, because reasons.

Save the file and restart the stack.

~/docker/nextcloud$ clear ; docker-compose restart ; docker logs -f nextcloud-web

I recommend open two more tabs/windows to keep an eye on logs of nextcloud-app and nextcloud-collabora.

~/docker/nextcloud$ clear ; docker logs -f nextcloud-app

~/docker/nextcloud$ clear ; docker logs -f nextcloud-collabora

In your browser open your URL. I always save the bookmark as “http://nextcloud.local.cites.aop” just to see Caddy change everything to HTTPS for me! :smiley:

As at this moment I am testing locally, I must agree and accept the self-signed certificate.

Nextcloud login screen opens.

After login:

  • close welcome animation

  • click con the little bell and see that all icons are fine (one of the errors is do not see the icons)

  • dismiss all notifications and accept (or not) notifications in your browser

  • click on the “A” (top left corner) and go to “Apps”

  • choose “Office & text” on the left

  • “Download and enable” Collabora Online (third top to bottom)

  • click on the “A” (top left corner) and go to “Settings”

  • click on “Overview” (left column) and enjoy that the only “warning” is about module php-imagick; there is a controversy if it must be installed and enabled or not (something about security, I did not investigate); if you want to install and enable, the command (for this image version I choose) is docker exec nextcloud-app apk add php7-pecl-imagick

  • scroll down the left column and click on “Nextcloud Office”

  • click “Use your own server”, check “Disable certificate verification (insecure)” and enter the same URL you are using to access your Nextcloud; in my case it would be “https://nextcloud.local.cites.aop” and click “Save”

  • you must be greeted by a “Saved” on the top right corner and a green checkmarked circle “Collabora Online server is reachable”

That’s it! (easy to say now, were more than three weeks Googling, reading forums, asking for help, etc)

You have latest Nextcloud, latest Collabora, latest Postgres (may change to Mariadb, if you choose to) all “powered” by Caddy!

@francislavoie thank you, all times I asked for help you readily helped.

The next challenge is to put this “stack” (including nextcloud-web-caddy) behind the REAL reverse-proxy! Another Caddy! :wink:
