+- docker 1.6.x
+
+## installation
+
+```
+cd /var/lib/dokku/plugins
+git clone https://github.com/dokku/dokku-mysql-plugin.git mysql
+dokku plugins-install-dependencies
+dokku plugins-install
+```
+

+
+```
+mysql:alias <name> <alias>     Set an alias for the docker link
+mysql:clone <name> <new-name>  NOT IMPLEMENTED
+mysql:connect <name>           Connect via mysql to a mysql service
+mysql:create <name>            Create a mysql service
+mysql:destroy <name>           Delete the service and stop its container if there are no links left
+mysql:export <name>            Export a dump of the mysql service database
+mysql:expose <name> <port>     NOT IMPLEMENTED
+mysql:import <name> <file>     NOT IMPLEMENTED
+mysql:info <name>              Print the connection information
+mysql:link <name> <app>        Link the mysql service to the app

+
+## usage
+
+```shell
+# create a mysql service named lolipop
+dokku mysql:create lolipop
+
+# you can also specify the image and image
+# version to use for the service
+# it *must* be compatible with the
+# official mysql image
+export MYSQL_IMAGE="mysql"
+export MYSQL_IMAGE_VERSION="5.5"
+dokku mysql:create lolipop
+
+# get connection information as follows
+dokku mysql:info lolipop
+
+# lets assume the ip of our mysql service is 172.17.0.1
+
+# a mysql service can be linked to a
+# container this will use native docker
+# links via the docker-options plugin
+# here we link it to our 'playground' app
+# NOTE: this will restart your app
+dokku mysql:link lolipop playground
+
+# the above will expose the following environment variables
+#
+#   DATABASE_URL=mysql://mysql:SOME_PASSWORD@172.17.0.1:3306/lolipop
+#   DATABASE_NAME=/playground/DATABASE
+#   DATABASE_PORT=tcp://172.17.0.1:3306
+#   DATABASE_PORT_3306_TCP=tcp://172.17.0.1:3306
+#   DATABASE_PORT_3306_TCP_PROTO=tcp
+#   DATABASE_PORT_3306_TCP_PORT=3306
+#   DATABASE_PORT_3306_TCP_ADDR=172.17.0.1
+
+# you can customize the environment
+# variables through a custom docker link alias
+dokku mysql:alias lolipop MYSQL_DATABASE
+
+# you can also unlink a mysql service
+# NOTE: this will restart your app
+dokku mysql:unlink lolipop playground
+
+# you can tail logs for a particular service
+dokku mysql:logs lolipop
+dokku mysql:logs lolipop -t # to tail
+
+# finally, you can destroy the container
+dokku mysql:destroy playground
+```
