canasta config

View and modify Canasta configuration

Synopsis

View and modify the .env configuration for a Canasta instance.

Use canasta config get to view current settings and canasta config set to change them. The set command handles side effects automatically (e.g., updating wikis.yaml when changing HTTPS_PORT) and restarts the instance. Editing .env by hand may leave the instance in an inconsistent state.

Key names are case-insensitive and hyphens are treated as underscores, so https-port, HTTPS_PORT, and Https_Port all work.

Settings safe to change on a running instance:

  Network
    HTTP_PORT                         HTTP port (default: 80)
    HTTPS_PORT                        HTTPS port (default: 443)

  PHP
    PHP_UPLOAD_MAX_FILESIZE           Upload file size limit (default: 10M)
    PHP_POST_MAX_SIZE                 POST data size limit (default: 10M)
    PHP_MAX_INPUT_VARS                Max input variables (default: 1000)

  Sitemaps
    MW_SITEMAP_PAUSE_DAYS             Days between sitemap refreshes (default: 1)

  Features
    CANASTA_ENABLE_ELASTICSEARCH      Enable Elasticsearch (default: false)
    CANASTA_ENABLE_OBSERVABILITY      Enable observability stack (default: false)
    CANASTA_ENABLE_VARNISH            Enable Varnish caching (default: true)
    CANASTA_ENABLE_WIKI_DIRECTORY     Show wiki directory on 404 pages (default: false)
    CANASTA_ENABLE_VERY_SHORT_URLS    Use /wiki/Page (no /w/) URLs (default: false)

  MediaWiki site
    MW_SITE_SERVER                    Site URL (e.g., https://example.com)
    MW_SITE_FQDN                      Domain name (e.g., example.com)

  Caddy / TLS
    CADDY_AUTO_HTTPS                  Set to "off" behind a reverse proxy
    CANASTA_STAGING_CERTS             Use Let's Encrypt staging CA (untrusted, but avoids rate limits) (default: false)

  Docker Image
    CANASTA_IMAGE                     Override the default Canasta image

  Backup (Restic)
    RESTIC_REPOSITORY                 Restic repo URL or local path
    RESTIC_PASSWORD                   Restic repo password

Restic backups also accept any backend-specific credentials whose keys start with AWS_, AZURE_, B2_, GOOGLE_, OS_, ST_, or RCLONE_ (e.g. AWS_ACCESS_KEY_ID for S3, AZURE_ACCOUNT_NAME for Azure, B2_ACCOUNT_ID for Backblaze). The entire .env is passed to the Restic container, so any variable Restic recognizes will work — see https://restic.readthedocs.io/en/stable/040_backup.html . SMTP credentials (SMTP_*) are also accepted.

Other settings (database passwords, secret keys, etc.) are generated by canasta create and should not be changed directly. To change the domain, first edit config/wikis.yaml, then use canasta config set to update MW_SITE_SERVER and MW_SITE_FQDN.
