MariaDB Dockerfile

Based on CentOS7 original mariadb Dockerfile, based on Stephen Tweedie's mariadb Dockerfile...

This repo contains a recipe for making Docker container for mariadb on CentOS7.


Check your Docker version

# docker version

Perform the build

# docker build --rm --tag <yourname>/mariadb55 .

Check the image out.

# docker images

Launching MariaDB

Quick start (not recommended for production use):

# docker run --name=mariadb -d -p 3306:3306 -e MYSQL_ROOT_PASSWORD=<password> <yourname>/mariadb

Recommended start

To use a separate data volume for /var/lib/mysql (recommended, to allow image update without
losing database contents):

Create a data volume container: (it doesn't matter what image you use
here, we'll never run this container again; it's just here to
reference the data volume)

# docker run --name=mariadb-data -v /var/lib/mysql <yourname>/mariadb55 true

And now create the daemonized mariadb container:

# docker run --name=mariadb -d -p 3306:3306 --volumes-from=mariadb-data -e MYSQL_ROOT_PASSWORD=<password> <yourname>/mariadb55

You could also create an additional database by passing MYSQL_DATABASE and/or create an additional user passing MYSQL_USER to the container.

Using your MariaDB container

Keep in mind the initial password set for mariadb is: mysqlPassword. Change it now:

# mysqladmin --protocol=tcp -u testdb -p<password> password myNewPass

Connecting to mariadb:

# mysql --protocol=tcp -utestdb -pmyNewPass

Create a sample table:

\> CREATE TABLE test (name VARCHAR(10), owner VARCHAR(10),
    -> species VARCHAR(10), birth DATE, death DATE);
