|
|
|
Extend pluie/alpine with mysql (mariadb) 5.5.47
|
|
Project comes with various scripts to execute basic tasks such as :
|
|
- dbcreate
|
|
- dbdump
|
|
- dbload
|
|
|
|
If database directory is empty a root user is created at startup.
|
|
Root access to database is only permit on localhost
|
|
|
|
## Image Size
|
|
|
|
- image ~ 172 MB
|
|
|
|
## 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 ...
|
|
```
