Nextcloud fpm with PostgreSQL and nginx, nginx-proxy-manager with LetsEncrypt example on amd64 Linux

Nextcloud fpm with PostgreSQL and nginx, nginx-proxy-manager with LetsEncrypt example on amd64 Linux

This repo contains custom configurations for running nextcloud fpm + postgresql + nginx and nginx-proxy-manager + LE as separate container. It was done by request of a random person over the internet, so I did not go too hard on documentation. There are also other ways to do this, but this one is the one I'm using.

• Requirements:
• Setup:
  • Environment variables
  • Basic Proxy configuration
  • Nextcloud configuration
  • OnlyOffice Document server

Warning

At time of publishing this repository there is a known "misalignment of view" between the majority of browsers + web-servers and IANA on the topic of js/mjs files that causes issues with Nextcloud itself. I will not go in much details, but after a while this repo will become obsolete. I will try to respond on requests, but don't expect me to maintain this.

Requirements

• Valid domain name with ability to change DNS settings / subdomains.
• Docker version 24.0.7 or newer.
• Docker Compose version v2.21.0 or newer.

Setup

Open a terminal as root and clone this repo in a folder where the containers will be stored.

mkdir docker-stuff && cd docker-stuff
git clone https://github.com/tzerber/docker_nc_psql_nginx_ssl.git .

A good suggestion is to have the the docker host having a static IP inside the network behind the firewall/nat. Forward port 80 and 443 from the internet to the IP of the docker host. Since this is very different depending on the network setup, this documentation will not go into details there.

Important

The nginx-proxy-manager container uses port 81 for the web-management interface. Port 81 on the docker host should not be accessible from the internet for safety reasons.

Environment variables

Edit the configurations for nextcloud in the following file:

nextcloud\db.env :

POSTGRES_PASSWORD=SuperSecretPassword
POSTGRES_DB=nextcloud
POSTGRES_USER=nextcloud

Important

There are also other configurations inside the compose files, nginx.conf and mime-types. They are not the default ones, and include custom configurations from my own instances based on experience. After some time nginx.conf and it's Dockerfile will need update once Nginx updates the mjs mime-type, but that's out of scope for this documentation. Same thing applies to Nextcloud's Dockerfile, once the check for php-bz2 is fixed the Dockerfile will need edit as well. Both of these exists because of NC28.0.1 so there shouldn't be any problems for now.

Basic Proxy configuration

In the terminal go to the proxy container and start it.

cd proxy
docker compose up --pull always -d

Make sure the new (sub)domain for Nextcloud is available and reachable, it can be verified by issuing this command in the terminal:

dig @8.8.8.8 full.fqdn.of.the.domain.com

and the output should be like this:

;; ANSWER SECTION:
full.fqdn.of.the.domain.com.    3600    IN      A       <your-server's-ip>

Then open a browser and go to your Host's IP addres on port 81, i.e. http://< ip >:81

Tip

Default login are [email protected] and password changeme.

Login to the web interface and correctly setup the login details.

Then go to the "Hosts" menu, and from there go to "Proxy hosts"

Setup a new host and make sure to enter the correct domain name, container name and port (port is 80)

Then go on the SSL tab and set up Lets Encrypt as shown on the image.

Important

Use a valid email address for LetsEncrypt. LE will send an email if there's a problem with the certificate in the future.

Click on save and wait for it to finish.

Nextcloud configuration

Build and start nextcloud and it's dependencies using this command in the terminal:

cd ../nextcloud
docker compose up --build --pull always -d

Give it a moment to load, then using a browser visit the freshly created domain name using https. Create an user and password for your admin account:

Caution

During writing of this document and testing all the steps, i found a bug in the default apps of NC28.

tl;dr Don't install the default suggested apps, Richdocuments Nextcloud office is broken again. I might include OnlyOffice at some point, because I actually use that instead of the default NC office.

Once everything is done, in the terminal where nextcloud containers we're started execute the following commands :

Add missing indices (this command must be executed after every upgrade)

docker compose exec -u www-data app php occ db:add-missing-indices

Add default phone region: the XX means default region for phone numbers using ISO 3166-1 country codes such as DE for Germany, FR for France. https://docs.nextcloud.com/server/latest/admin_manual/configuration_server/config_sample_php_parameters.html#default-phone-region

docker compose exec -u www-data app php occ config:system:set default_phone_region --value="XX"

Then from the browser go to the Admin settings, then Basic settings and fill out the email configuration:

Tip

Sometimes the admin panel is slow to recognize the phone code change. If that happens, execute the command again and give it a minute to refresh itself.

OnlyOffice Document server

ToDo

That's it, enjoy :)
