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
