# 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"
# you can also specify custom environment
# variables to start the mysql service
# in semi-colon separated forma
export MYSQL_CUSTOM_ENV="USER=alpha;HOST=beta"
# create a mysql service
dokku mysql:create lolipop
# get connection information as follows
dokku mysql:info lolipop
# 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 following environment variables will be set automatically by docker (not
# on the app itself, so they won’t be listed when calling dokku config)
#
# DOKKU_MYSQL_LOLIPOP_NAME=/lolipop/DATABASE
# DOKKU_MYSQL_LOLIPOP_PORT=tcp://172.17.0.1:3306
# DOKKU_MYSQL_LOLIPOP_PORT_3306_TCP=tcp://172.17.0.1:3306
# DOKKU_MYSQL_LOLIPOP_PORT_3306_TCP_PROTO=tcp
# DOKKU_MYSQL_LOLIPOP_PORT_3306_TCP_PORT=3306
# DOKKU_MYSQL_LOLIPOP_PORT_3306_TCP_ADDR=172.17.0.1
#
# and the following will be set on the linked application by default
#
# DATABASE_URL=mysql://mysql:SOME_PASSWORD@dokku-mysql-lolipop:3306/lolipop
#
# NOTE: the host exposed here only works internally in docker containers. If
# you want your container to be reachable from outside, you should use `expose`.
# another service can be linked to your app
dokku mysql:link other_service playground
# since DATABASE_URL is already in use, another environment variable will be
# generated automatically
#
# DOKKU_MYSQL_BLUE_URL=mysql://mysql:ANOTHER_PASSWORD@dokku-mysql-other-service:3306/other_service
# you can then promote the new service to be the primary one
# NOTE: this will restart your app
dokku mysql:promote other_service playground
# this will replace DATABASE_URL with the url from other_service and generate
# another environment variable to hold the previous value if necessary.
# you could end up with the following for example:
#
# DATABASE_URL=mysql://mysql:ANOTHER_PASSWORD@dokku-mysql-other_service:3306/other_service
# DOKKU_MYSQL_BLUE_URL=mysql://mysql:ANOTHER_PASSWORD@dokku-mysql-other-service:3306/other_service
# DOKKU_MYSQL_SILVER_URL=mysql://mysql:SOME_PASSWORD@dokku-mysql-lolipop:3306/lolipop
# you can also unlink a mysql service
# NOTE: this will restart your app and unset related environment variables
dokku mysql:unlink lolipop playground
# you can tail logs for a particular service
dokku mysql:logs lolipop
dokku mysql:logs lolipop -t # to tail
# you can dump the database
dokku mysql:export lolipop > lolipop.sql
# you can import a dump
dokku mysql:import lolipop < database.sql
# you can clone an existing database to a new one
dokku mysql:clone lolipop new_database
# finally, you can destroy the container
dokku mysql:destroy lolipop
