See Database containers for documentation and usage that is common to all relational database container types.
Overriding MySQL my.cnf settings
For MySQL databases, it is possible to override configuration settings using resources on the classpath. Assuming
is a directory on the classpath containing .cnf files, the following URL can be used:
Any .cnf files in this classpath directory will be mapped into the database container's /etc/mysql/conf.d directory, and will be able to override server settings when the container starts.
root user password
If no custom password is specified, the container will use the default user password
test for the
root user as well.
When you specify a custom password for the database user,
this will also act as the password of the MySQL
root user automatically.
Adding this module to your project dependencies
Add the following dependency to your
<dependency> <groupId>org.testcontainers</groupId> <artifactId>mysql</artifactId> <version>1.17.2</version> <scope>test</scope> </dependency>
Adding this Testcontainers library JAR will not automatically add a database driver JAR to your project. You should ensure that your project also has a suitable database driver as a dependency.
