Image Volumes

/var/lib/mysql          # mysql database directory  
/dump                   # directory to store various mysql scripts  

ENV variables

     MYSQL_DATABASE     # create specified database at startup  
         MYSQL_USER     # create specified user at startup (and grant all rights to MYSQL_DATABASE)  
     MYSQL_PASSWORD
MYSQL_ROOT_PASSWORD     # don't really need it. a random root password is generated if none  

Inherit ENV variables

   SHENV_CTX=LOCAL      # LOCAL|INT|PROD change context bg color
  SHENV_NAME=Mysql      # container name 
 SHENV_COLOR=97         # ANSI EXTENDED COLOR CODE

Image Usage

for example to start a new project :

$ cd /home/docker;
$ mkdir -p db/{mysql,dump}

$ docker run --name mysql \
-v $(pwd)/db/mysql:/var/lib/mysql \
-v $(pwd)/db/dump:/dump \
-e MYSQL_DATABASE=mybase \
-e MYSQL_USER=dev \
-e MYSQL_PASSWORD=mysql \
-it pluie/alpine-mysql

you don't need to expose your localhost mysql port. for example :

$ docker run --name pma -p 8080:80 --link mysql:db -d phpmyadmin/phpmyadmin

and phpmyadmin is accessible via http://localhost:8080/ and linked to your mysql container

Existing Scripts

create a new database with full rights to a user :

$ docker exec -it mysql /dbcreate mydbname myuser

load an export file in particular database :

$ docker exec -it mysql /dbload mydbname /dump/mydbname.init.sql

dump a database :

$ docker exec -it mysql /dbdump mydbname

More specific actions as user

to connect to the mysql server as user from host :

mysql -h ipmysqlcontainer -udev -pmysql

to retriew container ip you can run first :

docker inspect --format='{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' mysql

to connect to the mysql server as user from container :

$ docker exec -it mysql "mysql -udev -pmysql"

More specific actions as root

to connect to the mysql server as root :

$ docker exec -it mysql "mysql -uroot"

to connect to the mysql container as root :

docker exec -it mysql bash

then

$ mysql -uroot mybase < /dump/init.mybase.sql
$ mysqldump -uroot mybase > /dump/last.mybase.dump.sql

etc.

Link Container

to link this container to another, use the default docker behavior (as the example provide with phpmyadmin) :

docker run --name mycontainer --link mysql:db ...
