taosnet/mariadb repository overview

⁠Description

Alpine linux based mariadb image.

⁠Usage

⁠Start a Server Instance

Basic usage is simple, use the image as if you are running mysqld_safe.

docker run --name=mariadb taosnet/mariadb

In this form, the root password will be set to a randomly generated password that will be output to stdout on the container. You can change the password by running:

docker exec -ti mariadb /usr/bin/mysqladmin -h localhost -p'randomPassword' password 'newPassword'

Alternatively you can set the root password with an environmental variable MYSQL_ROOT_PASSWORD on startup:

docker run --name=mariadb -e MYSQL_ROOT_PASSWORD='myPassword' taosnet/mariadb

⁠Connect From Another Container

You can connect to your server instance by linking the server container to your app:

docker run --name=myapp --link mariadb:db taosnet/myapp

⁠Environment Variables

⁠MYSQL_ROOT_PASSWORD

This variable specifies the root password for the database. If not specified, a random password will be generated as the root password and output to stdout.

⁠MYSQL_DATABASE

If present, intialize a database with the name given in this variable.

⁠MYSQL_USER

Database user to create with access to the initialized database. Both MYSQL_DATABASE and MYSQL_PASSWORD must be present in addition to MYSQL_USER for the user to be created. If either of them are missing, this variable is ignored. If MYSQL_HOST is specified, then the user's access is restricted to that host. Otherwise the user's access is restricted to localhost.

⁠MYSQL_PASSWORD

The database password for the user specified by MYSQL_USER. See conditions above. If the conditions are not met, this variable is ignored.

⁠MYSQL_HOST

Host to restrict MYSQL_USER to. If MYSQL_USER is not create, this variable is ignored.

⁠Initializing With Data

You can initialize the container with data located in /docker-entrypoint-initdb.d. The files should have the extension .sql and contain valid SQL statements. The files are run in alphabetical order as determined by the ls command.
