dockette/adminer:mssql

Debian-based image with Microsoft ODBC Driver 18 and PHP sqlsrv / pdo_sqlsrv extensions.

docker run \
    --rm \
    -p 8080:80 \
    dockette/adminer:mssql

By default, TrustServerCertificate is set to yes so the image works out of the box with self-signed certificates (common in development). You can control encryption behavior via environment variables:

Variable	Description	Default
ADMINER_PLUGIN_MSSQL_ENCRYPT	Set to 0 to disable the encryption plugin	enabled
ADMINER_MSSQL_ENCRYPT	yes, no, or strict	not set
ADMINER_MSSQL_TRUST_CERT	yes or no	yes

dockette/adminer:dg

Customization for the best database management tool written in PHP, Adminer

You should take a look to the official github profile (https://github.com/dg/adminer-custom).

Plugins

Adminer plugins can be enabled via environment variables. All plugins are disabled by default. Available for all image variants except dg.

Autologin

Skips the login form and connects directly to a database server.

Variable	Description
ADMINER_PLUGIN_AUTOLOGIN=1	Enable the autologin plugin
ADMINER_AUTOLOGIN_SERVER	DSN connection string

DSN format: driver://username:password@host:port/database

docker run \
    --rm \
    -p 8080:80 \
    -e ADMINER_PLUGIN_AUTOLOGIN=1 \
    -e ADMINER_AUTOLOGIN_SERVER=server://root:secret@mysql:3306/mydb \
    dockette/adminer:full

Supported drivers: server (MySQL/MariaDB), pgsql, sqlite, mongo, oracle, elastic.

Server List

Displays a dropdown of pre-configured database servers with an Auto Sign-In button. Credentials are handled server-side and never exposed to the browser.

Variable	Description
ADMINER_PLUGIN_SERVER_LIST=1	Enable the server list plugin
ADMINER_SERVERS_<Name>	DSN for each server (suffix becomes the display name)

docker run \
    --rm \
    -p 8080:80 \
    -e ADMINER_PLUGIN_SERVER_LIST=1 \
    -e ADMINER_SERVERS_MySQL=server://root:secret@mysql:3306/mydb \
    -e ADMINER_SERVERS_PostgreSQL=pgsql://postgres:pwd@pg:5432/app \
    -e ADMINER_SERVERS_DevDB=server://dev@devhost:3306 \
    dockette/adminer:full

Servers without credentials in the DSN (e.g. server://devhost:3306) appear in the dropdown but require manual login. The Auto Sign-In button only appears for servers with stored credentials.

Note: Autologin takes precedence over Server List. If both plugins are enabled, only Autologin is activated.

Themes

You can apply a theme by setting the ADMINER_THEME environment variable:

docker run \
    --rm
    -p 8000:80
    -e ADMINER_THEME=dracula
    dockette/adminer:full

If the specified theme is not found, the container will list all available themes.

Available Themes

default	adminer-dark	brade	bueltge	dracula
esterka	flat	galkaev	haeckel	hever
konya	lavender-light	lucas-sandery	mancave	mvt
