Adminer Docker Container Image

Docker Images

Use image revision tags such as wodby/adminer:6-rN to select a Wodby image revision. Major and minor tags use the repository release number, starting at r0. Full-version tags such as wodby/adminer:6.1.0-r0 start at r0 for each exact upstream version. Every published versioned revision tag has a matching annotated Git tag pointing to its release commit. Existing tags remain available after support for their major or minor version ends. See release tags for available revisions and the image revision policy for upgrade guidance. Previously published image tags remain available.

Overview:

• Base image: wodby/php 8.4-apache (Alpine Linux), pinned by digest: Apache in front of PHP-FPM in one container
• GitHub actions builds
• Docker Hub

Supported tags and respective Dockerfile links:

• 6.3, 6, latest (Dockerfile)

Plugin loader scripts used from TimWolla/docker-adminer.

All images built for linux/amd64 and linux/arm64

Environment Variables

Variable	Default Value	Description
ADMINER_DEFAULT_DB_DRIVER	server	server is the same as mysql, pgsql for PostgreSQL
ADMINER_DEFAULT_DB_HOST
ADMINER_DEFAULT_DB_NAME
ADMINER_DESIGN		Adminer theme, e.g. nette
ADMINER_PLUGINS		Separated by space, e.g. tables-filter
PHP_MAX_EXECUTION_TIME	0
PHP_MEMORY_LIMIT	512M
PHP_POST_MAX_SIZE	512M
PHP_UPLOAD_MAX_FILESIZE	512M

The variables of wodby/php, including its -apache variant, apply as well. APACHE_FCGI_PROXY_TIMEOUT is 86400, so long imports and exports run as long as PHP allows.

The container starts as root and Apache and PHP-FPM serve requests as www-data, so it also runs where privilege escalation is disallowed.

Upgrading to Adminer 6

Review ADMINER_PLUGINS when upgrading from Adminer 5. Adminer 6 removed the tinymce, edit-calendar, json-column, pretty-json-column, translation, email-table, dump-php, and master-slave plugins (upstream change). Remove these names from your configuration; unavailable plugins stop container startup. Removing tinymce also removes its rich-text editing functionality.

Space-separated plugin lists are still supported. For example:

ADMINER_PLUGINS: tables-filter edit-textarea

Upgrading from images before the wodby/php base

Images built on the official Debian-based php:8.4-apache image ran Apache with PHP as an Apache module. The image now runs Apache and PHP-FPM on Alpine Linux. Port 80 and the variables above are unchanged. Apache configuration mounted into Debian's /etc/apache2/sites-enabled or /etc/apache2/conf-enabled must move to /etc/apache2/conf.d/*.conf.

Deployment

Deploy Adminer to your own server via Wodby.
