Create the traefik network

docker network create traefik

Docker Swarm

docker swarm init

Mount NFS NAS Share

We need the nfs-utils package installed.

sudo mount -t nfs -o nfsvers=4 192.168.1.110:/media /WHERE/TO/MOUNT
sudo mount -t nfs -v 192.168.1.110:/media /home/knast/shares/disk1

if mounting on host, add to fstab

192.168.1.110:/media       /home/null/shares/disk1    nfs rw,auto,vers=3,nofail,noatime,nolock,timeo=14 0 0

Or create a docker volume for the nfs mount that can then be accessed in compose file:

docker volume create --driver local --opt type=nfs --opt o=addr=192.168.1.110,rw,vers=4 --opt device=:/media --name nfs_data

The volume can then be mounted in the compose file in the following way:

version: "3" 
services: 
  web-server: 
    image: nginx:latest 
    ports: 
      - 1212:80 
    volumes:
      - nfs_data:/usr/share/nginx/html

volumes:
  nfs_data:
    external: true

networks:
  traefik:
    external: true

### Firewall

```sh
sudo ufw allow 80,443,22,8096,8097,8384,3040,51820,51821,21027,32400,2222,8888,4444,22000/tcp
sudo ufw allow 80,443,22,8096,8097,8384,3040,51820,51821,21027,32400,2222,8888,4444,22000/udp

## Fstab 
using the `blkid` command to mount an external drive in fstab to use for restic backups

```sh
# /etc/fstab: static file system information.

UUID=6fb3bc60-e984-43ce-a688-151b49f558e0 /home/null/shares/disk2 auto defaults,nofail,x-systemd.automount 0 2

Gitlab

After adding the domain name to the docker-compose.yml and the gitlab configuration:

        hostname: 'gitlab.knast.cc'
        environment:
            GITLAB_OMNIBUS_CONFIG: |
              external_url 'https://gitlab.knast.cc'

We also need to please the dark lords of reverse proxying by adding the following lines to the gitlab.rb configuration:

nginx['listen_port'] = 80
nginx['listen_https'] = false

Nextcloud

edit the nextcloud config.php to use the https protocol

nano /srv/nextcloud/config/config.php

We also use traefik and docker. I have added the following traefik label in our docker-compose.yml:

- "traefik.http.middlewares.nc-header.headers.customRequestHeaders.X-Forwarded-Proto=https" 

And in the config.php, I’ve also added some values regarding reverse proxies:

  'forwarded_for_headers' => 
  array (
    1 => 'HTTP_X_FORWARDED',
    2 => 'HTTP_FORWARDED_FOR',
    3 => 'HTTP_FORWARDED',
    0 => 'HTTP_X_FORWARDED_FOR',
  ),
  'trusted_proxies' => 
  array (
    0 => '10.0.0.0/8',
  ),

Connecting a container directly to an NFS mount

version: "3" 
services: 
web-server: 
   image: nginx:latest 
   ports: 
      - 80:80 
   volumes: 
      - type: volume 
      source: nfs-volume 
      target: /nfs 
      volume: 
      nocopy: true 
volumes: 
   nfs-volume: 
   driver_opts: 
   type: "nfs" 
   o: "addr=192.168.1.110,nolock,soft,rw" 
   device: ":/var/data"
