Usage

1. Listen on loopback interface only

$ docker run -i     -p 127.0.0.1:3306:3306     -e MYSQL_ROOT_PASSWORD=my-secret-pw     -t cytopia/mysql-8.0# Access MySQL from your host computer$ mysql --user=root --password=my-secret-pw --host=127.0.0.1 -e ‘show databases;‘

2. Enable logging

Enable logging and mount the log directory to your host to ~tmp/mysql-log

$ docker run -i     -p 127.0.0.1:3306:3306     -v ~tmp/mysql-log:/var/log/mysql     -e MYSQL_ROOT_PASSWORD=my-secret-pw     -e MYSQL_GENERAL_LOG=1     -t cytopia/mysql-8.0# Access MySQL from your host computer$ mysql --user=root --password=my-secret-pw --host=127.0.0.1 -e ‘show databases;‘

3. Mount MySQL socket to the host

Use MySQL socket for localhost connections through the socket. No need to expose the MySQL port to the host in this case.

$ docker run -i     -v ~tmp/mysql-sock:/var/sock/mysqld     -e MYSQL_ROOT_PASSWORD=my-secret-pw     -t cytopia/mysql-8.0# Access MySQL from your host computer via socket$ mysql --user=root --password=my-secret-pw --socket=/var/sock/mysqld/mysqld.sock -e ‘show databases;‘

4. Overwrite configuration

You can also add any configuration settings prior startup to MySQL.

# Create local config with buffer overwrite$ printf "[mysqld]\n%s\n" "key_buffer = 500M" > ~/tmp/mysqld_config/buffer.cnf$ docker run -i     -p 127.0.0.1:3306:3306     -v ~/tmp/mysqld_config:/etc/mysql/conf.d     -e MYSQL_ROOT_PASSWORD=my-secret-pw     -t cytopia/mysql-8.0

MySQL Configuration overview

2	/etc/mysql/conf.d/	Custom configuration (level 1). Can be mounted to provide custom *.cnf files which can overwrite anything of the above. (used by the devilbox for its base configuration)
3	/etc/mysql/docker-default.d/*.cnf	Custom configuration (level 2). Can be mounted to provide custom *.cnf files which can overwrite anything of the above. (used by the devilbox to allow custom user-defined configuration overwriting the default devilbox settings.
