This guide covers configuring continuous integration pipelines for projects that have a MySQL dependency. If you’re new to Drone please read our Tutorial and build configuration guides first.

Basic Example

In the below example we demonstrate a pipeline that launches a MySQL service container. The server will be available at localhost:3306.

kind: pipeline
type: kubernetes
name: default

steps:
- name: test
  image: mysql
  commands:
  - sleep 15
  - mysql -u root --execute="SELECT VERSION();"

services:
- name: database
  image: mysql
  environment:
    MYSQL_ALLOW_EMPTY_PASSWORD: 'yes'
    MYSQL_DATABASE: test

Database Options

If you need to start the mysql container with additional runtime options you can override the entrypoint and command arguments.

services:
- name: database
  image: mysql
  entrypoint: [ "mysqld" ]
  command: [ "--character-set-server=utf8mb4" ]

Database Settings

The official MySQL image provides environment variables used at startup to create the default username, password, database and more. Please see the official image documentation for more details.

Common Problems

If you are unable to connect to the MySQL container please make sure you are giving MySQL adequate time to initialize and begin accepting connections.
