How to run Collabora office for Nextcloud using docker-compose

Create this docker-compose.yml, e.g. in /opt/collabora-mydomain:

services:
  code:
    image: collabora/code:latest
    restart: always
    environment:
      - password=${COLLABORA_PASSWORD}
      - username=${COLLABORA_USERNAME}
      - aliasgroup1=https://collabora.mydomain.com:443
      - aliasgroup2=https://nextcloud.myseconddomain.com:443
      - server_name=collabora.mydomain.com
      - extra_params=--o:ssl.enable=true
    ports:
      - 9980:9980
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.collabora.rule=Host(`collabora.mydomain.com`)"
      - "traefik.http.routers.collabora.entrypoints=websecure"
      - "traefik.http.routers.collabora.tls.certresolver=cloudflare"
      - "traefik.http.routers.collabora.tls.domains[0].main=mydomain.com"
      - "traefik.http.routers.collabora.tls.domains[0].sans=*.mydomain.com"
      - "traefik.http.services.collabora.loadbalancer.server.port=9980"
      - "traefik.http.services.collabora.loadbalancer.server.scheme=https"

If required, add more aliasgroups as needed.

Now create this .env with the configuration. You need to change the password and the domain!

COLLABORA_USERNAME=admin
COLLABORA_PASSWORD=veecheit0Phophiesh1fahPah0Wue3

Now you can create a systemd service to autostart by using our script from Create a systemd service for your docker-compose project in 10 seconds.

Run from inside your directory (e.g. /opt/collabora-mydomain)

curl -fsSL https://techoverflow.net/scripts/create-docker-compose-service.sh | sudo bash /dev/stdin

Traefik config

All relevant traefik config is already in the docker-compose.yml. You need to have Traefik running and configured to use the cloudflare certresolver.

See this TechOverflow post for the Traefik configuration we’re using.

nginx config.

Note: I generally recommend using Traefik.

Now you need to configure your reverse proxy to point to port 9980. Here’s an example nginx config:

server {
    server_name collabora.mydomain.com;

    access_log /var/log/nginx/collabora.mydomain.com.access_log;
    error_log /var/log/nginx/collabora.mydomain.com.error_log info;

    location / {
        proxy_pass https://127.0.0.1:9980;
        proxy_http_version 1.1;
        proxy_read_timeout 3600s;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_set_header Host            $host;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
        add_header X-Frontend-Host $host;
        add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
    }

    listen [::]:80; # managed by Certbot
}

Now open your browser and open collabora.mydomain.com. If collabora is running correctly, you should see:

OK

In Nextcloud, goto https://nextcloud.mydomain.com/settings/admin/richdocuments and set the URL (and Port) of Collabora Online-server to:

https://admin:[email protected]

Ensure to use your custom password from .env and your custom domain!

Click Save and you should see Collabora Online server is reachable:
