How to configure collabora CODE with docker for Nextcloud snap

This example will require Docker and a Reverse proxy for the CODE server.

Install Docker on host. Create a DNS for subdomain like office.mydomain.xyz. Create a proxy host for https on port 9980 on reverse proxy pointing to that host and get the domain name encrypted.

Docker Stack:

name: 'code'

services:
  collabora:
    image: collabora/code
    container_name: collabora
    environment:
      - domain=cloud.mydomain.tld  # Replace with your actual domain # disable when using aliasgroups
      # - aliasgroup1=https://cloud.mydomain.tld:443,https://cloud\\.mydomain\\.tld:443 # enable for aliasgroup1
      # - aliasgroup2=https://cloud.otherdomain.tld:443,https://cloud\\.otherdomain\\.tld:443 # enable for aliasgroup2
      # - aliasgroup3=https://cloud.somedomain.tld:443,https://cloud\\.somedomain\\.tld:443 # enable for aliasgroup3
      - username=admin
      - password=********         # Replace with a strong password
      - extra_params=--o:ssl.enable=true
      - dictionaries=en_US,de_DE
    ports:
      - "9980:9980"
    restart: always

Tip

- domain automatic for first/single domain

- aliasgroup iterating 1,2,3 for multiple domains IMPORTANT: keep \\

- dictionaries add or remove dictionaries comma seperated

WOPI is not necessary when defining aliasgroups

Collabora Docker options (multiple nextcloud clients)

Each aliasgroup represents the allowed "client" domain, which will prevent unregistered clients from accessing the CODE server. Thus using aliasgroups resolves the issue of allowed WOPI client IP's.

Tip

disable the - domain= environment (by commenting #) when using - aliasgroup=, enable - aliasgroup by uncommenting #

be aware of the domain formatting conventions when defining WOPI clients using \\ as separator before .

# - domain=cloud.mydomain.tld  # Replace with your actual domain # disable when using aliasgroups
- aliasgroup1=https://cloud.mydomain.tld:443,https://cloud\\.mydomain\\.tld:443
- aliasgroup2=https://cloud.otherdomain.tld:443,https://cloud\\.otherdomain\\.tld:443
- aliasgroup3=https://cloud.somedomain.tld:443,https://cloud\\.somedomain\\.tld:443

Dictionaries

-e ‘dictionaries=de_DE,en_GB,en_US’
