How to configure collabora CODE with docker

How to configure Collabora CODE with docker for Nextcloud snap

Please prefer the Nextcloud community how-to

Note

Be aware, this how to is as-is and is not supported by the Nextcloud snap team!

• CODE Docker image — SDK https://sdk.collaboraonline.com/ documentation
• Configuration — SDK https://sdk.collaboraonline.com/ documentation

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.tld. Create a proxy host for http 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:latest
    container_name: collabora
    environment:
      - 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
      - dictionaries=en_GB en_US de_DE
      - extra_params=
      --o:ssl.enable=false 
      --o:ssl.termination=true
      --o:logging.level=warning
      --o:user_interface.mode=compact
    ports:
      - "9980:9980"
    restart: always

Tip

- extra_params=--o:ssl.enable=false --o:ssl.termination=true disabling ssl in coolsweed/collabora and forwarding http in reverse proxy handling ssl termination.

- aliasgroup iterating 1,2,3 for multiple domains. IMPORTANT: be aware of formatting conventions using \\ as separator before .

- dictionaries add dictionaries space seperated en_US en_GB de_DE etc.

WOPI is not necessary when defining aliasgroups as allowed hosts

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.

- 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

Collabora Docker parameters

optional extra parameters etc. refer to the docs

    -extra_params=
        --o:ssl.enable=false disable ssl termination in coolswd/collabora
        --o:ssl.termination=true forwarding http to reverse proxy handling ssl termination
        --o:mount_jail_tree=true
        --o:home_mode.enable=true
        --o:logging.level_startup=warning
        --o:logging.disable_server_audit=true

Dictionaries

- dictionaries=en_GB en_US de_DE
