owncloud

ownCloud Server: file sync and share, with web, desktop and mobile clients.

Three containers: owncloud, mariadb for metadata, users and shares, and redis for file locking and the distributed cache.

Setup

  1. Set OWNCLOUD_DOMAIN, OWNCLOUD_ADMIN_PASSWORD, DB_PASSWORD and DB_ROOT_PASSWORD.
  2. Map the domain to port 8080 and deploy. The first start installs ownCloud and creates the admin account.
  3. Log in with OWNCLOUD_ADMIN_USERNAME / OWNCLOUD_ADMIN_PASSWORD.

Health check: /usr/bin/healthcheck, the image's own script, also the compose healthcheck.

Environment

Variable Default Purpose
OWNCLOUD_DOMAIN — Public hostname, without scheme
OWNCLOUD_ADMIN_USERNAME / OWNCLOUD_ADMIN_PASSWORD admin / — Admin account
DB_NAME / DB_USER / DB_PASSWORD owncloud / owncloud / — Database credentials, read by both containers
DB_ROOT_PASSWORD — MariaDB root password

OWNCLOUD_DOMAIN also fills OWNCLOUD_TRUSTED_DOMAINS; ownCloud rejects requests for any host not on that list.

The admin variables are read only by the first-start install. Changing them later does not change the account; use the web UI or occ user:resetpassword.

The database credentials are stored inside the MariaDB data directory when it is first created. Changing them in the environment afterwards breaks the connection rather than changing the password.

Storage

Volume Mount Holds
owncloud-data /mnt/data User files, apps, config.php
owncloud-mysql-data /var/lib/mysql The database

Redis has no named volume. It holds only locks and cache, which ownCloud rebuilds after a restart.

owncloud/server:10 tracks the 10.x line. latest points at the same release today, but ownCloud now also publishes 11.x, and a move to a new major should be a deliberate upgrade with a backup, not a side effect of a pull.

mariadb:12 and redis:6 track their major versions. A MariaDB data directory cannot move back to an older major, so back up the database volume before changing it.
