+-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
 ```
 
-### Root Usage
+and phpmyadmin is accessible via http://localhost:8080/ and linked to your mysql container
 
-a root user is created at startup (if database directory is empty)  
-root login is permit only on localhost   
-to do things without files you can run :
+
+### 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 do things with files you can log in to container :  
+to connect to the mysql container as root :  
 ```
 docker exec -it mysql bash
 ```
 then  
 ```
-$ mysql -uroot mybase < /dump/mydump.sql
+$ mysql -uroot mybase < /dump/init.mybase.sql
+$ mysqldump -uroot mybase > /dump/last.mybase.dump.sql
 ```
-etc.

-### User usage
-
-locally (on host) you can run (with appropriate user : pass) :  
-```
-mysql -h ipmysqlcontainer -udev -pmysql
-```
-or if you want use the mysql client of the container :
-```
-docker exec -it mysql "mysql -h ipmysqlcontainer -udev -pmysql"
