Having a private cloud

I have finally migrated from my local server to a server. Here is how I setup my own Nextcloud.

The Server

Once more we need a server. I use stratos Linux V40 Server for this. At 1€ for 3 Months and then 15€/Month it is not too expensive considering I get 1tb ssd diskspace, 32gb ram and 8 CPU vCores.

The Domain

I am still using namecheap. Since I already have a domain for my blog, i just created a subdomain (included) called cloud.mydomain.com

The Setup

Since I use Docker for my services here is what I used

The Stack

  • Nextcloud
  • MariaDB
  • Traefik

Traefik

version: '3.7'

services:
  traefik:
    image: traefik
    command: 
      - "--providers.docker"
      - "--providers.docker.exposedByDefault=false"
      - "--providers.docker.network=traefik"
      - "--entrypoints.http.address=:80"
      - "--entrypoints.http.http.redirections.entrypoint.to=https"
      - "--entrypoints.http.http.redirections.entrypoint.scheme=https"
      - "--entrypoints.https.address=:443"
      - "--entrypoints.https.http.tls.certResolver=le"
      - "--certificatesresolvers.le.acme.tlschallenge=true"
      - "--certificatesresolvers.le.acme.email=your@mail.com"
      - "--certificatesresolvers.le.acme.storage=/letsencrypt/acme.json"
    ports:
      - 80:80
      - 443:443
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./letsencrypt:/letsencrypt
    networks:
      - web

networks:
  web: 
    name: traefik

Nextcloud/MariaDB

version: '3.7'
services:

  nextcloud:
    container_name: nextcloud
    restart: unless-stopped
    image: nextcloud
    labels:
      - 'traefik.enable=true'
      - "traefik.http.routers.cloud.rule=Host(`cloud.yourdomain.com`)"
      - 'traefik.http.services.nextcloud.loadbalancer.server.port=80'

      - 'traefik.http.middlewares.header-nextcloud.headers.stsincludesubdomains=true'
      - 'traefik.http.middlewares.header-nextcloud.headers.stspreload=true'
      - 'traefik.http.middlewares.header-nextcloud.headers.stsseconds=15552000'
      - 'traefik.http.middlewares.header-nextcloud.headers.customFrameOptionsValue=SAMEORIGIN'
      - 'traefik.http.middlewares.header-nextcloud.headers.browserXssFilter=true'
      - 'traefik.http.middlewares.header-nextcloud.headers.contentTypeNosniff=true'
      - 'traefik.http.middlewares.header-nextcloud.headers.referrerPolicy=no-referrer'
      - 'traefik.http.routers.nextcloud.middlewares=header-nextcloud'
    networks:
      - cloud
      - traefik
    volumes:
      - ./apps:/var/www/html/apps
      - ./config:/var/www/html/config
      - ./data:/var/www/html/data
    depends_on:
      - db

# in nextcloud db web-setup enter maria-db.nextcould_cloud
  db:
    container_name: maria-db
    restart: unless-stopped
    image: mariadb
    networks:
      - cloud
    env_file:
      - cloud.env
    volumes:
      - ./mariadb:/var/lib/mysql
networks:
  cloud: 
  traefik:
    external: true

The .env-File

MYSQL_ROOT_PASSWORD='a_complex_admin_password'
MYSQL_DATABASE='what_do_you_call_your_database'
MYSQL_USER='Your_Custom_UserName'
MYSQL_PASSWORD='Custom_User_Password'
OVERWRITEPROTOCOL='https'

Run it

# start the traefik docker compose file
docker compose -f docker-compose.traefik.yml up -d

#start the nextcloud/MariaDB compose file
docker compose -f docker-compose.cloud.yml

If you now go to your cloud.yourdomain.com you will get a setup screen. Expand the DB-Section, select MariaDB, enter your credentials from your .env file (not the admin password!). And Voilá, you got yourself your very own cloud :)

Have fun.

Troubleshooting

Bug #1 - desktop client complains about polling url not being https

To fix this, on your server, go to the folder containing your nextcloud docker compose file. There should be a config folder if you started it once.
In that config folder go to the <php.config> file.

make sure these 3 lines are contained or add them

  'trusted_domains' => 
  array (
    0 => 'cloud.yourdomain.com',
  ),
  'overwrite.cli.url' => 'http://cloud.yourdomain.com',
  'overwriteprotocol' => 'https',

Restart nextcloud once to activate the new config.

cd path/to/your/nextcloud/folder
docker compose -f docker-compose.cloud.yml down
docker compose -f docker-compose.cloud.yml up -d

Bug #2 - desktop client complains about bad json

This bug occured for me because I had another instance of nextcloud locally. Logout of your existing account and try again - that's it.
