Connect to mysql in a docker container from the host

Question

(It\'s probably a dumb question due to my limited knowledge with Docker or mysql administration, but since I spent a whole evening on this issue, I dare to ask it.)

Answer 1

I recommend checking out docker-compose. Here's how that would work:

Create a file named, docker-compose.yml that looks like this:

version: '2'

services:

  mysql:
    image: mariadb:10.1.19
    ports:
      - 8083:3306
    volumes:
      - ./mysql:/var/lib/mysql
    environment:
      MYSQL_ROOT_PASSWORD: wp

Next, run:

$ docker-compose up

Notes:

• For latest mariadb image tag see https://hub.docker.com/_/mariadb/

Now, you can access the mysql console thusly:

$ mysql -P 8083 --protocol=tcp -u root -p

Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 8
Server version: 5.5.5-10.1.19-MariaDB-1~jessie mariadb.org binary distribution

Type 'help;' or '\h' for help. Type '\c' to clear the current input statement.

Notes:

• You can pass the -d flag to run the mysql/mariadb container in detached/background mode.

• The password is "wp" which is defined in the docker-compose.yml file.

• Same advice as maniekq but full example with docker-compose.
