You can also specify the image and image version to use for the service. It must be compatible with the mariadb image.
export MARIADB_IMAGE="mariadb"
export MARIADB_IMAGE_VERSION="${PLUGIN_IMAGE_VERSION}"
dokku mariadb:create lollipop
You can also specify custom environment variables to start the mariadb service in semicolon-separated form.
export MARIADB_CUSTOM_ENV="USER=alpha;HOST=beta"
dokku mariadb:create lollipop

# usage
dokku mariadb:list
List all services:
dokku mariadb:list
# usage
dokku mariadb:logs <service> [-t|--tail] <tail-num-optional>
flags:
-t|--tail [<tail-num>]
: do not stop when end of the logs are reached and wait for additional output
You can tail logs for a particular service:
dokku mariadb:logs lollipop
By default, logs will not be tailed, but you can do this with the --tail flag:
dokku mariadb:logs lollipop --tail
The default tail setting is to show all logs, but an initial count can also be specified:
dokku mariadb:logs lollipop --tail 5
# usage
dokku mariadb:link <service> <app> [--link-flags...]
flags:
-a|--alias "BLUE_DATABASE"
: an alternative alias to use for linking to an app via environment variable-q|--querystring "pool=5"
: ampersand delimited querystring arguments to append to the service link-n|--no-restart "false"
: whether or not to restart the app on link (default: true)
A mariadb 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 mariadb:link lollipop 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_MARIADB_LOLLIPOP_NAME=/lollipop/DATABASE
DOKKU_MARIADB_LOLLIPOP_PORT=tcp://172.17.0.1:3306
DOKKU_MARIADB_LOLLIPOP_PORT_3306_TCP=tcp://172.17.0.1:3306
DOKKU_MARIADB_LOLLIPOP_PORT_3306_TCP_PROTO=tcp
DOKKU_MARIADB_LOLLIPOP_PORT_3306_TCP_PORT=3306
DOKKU_MARIADB_LOLLIPOP_PORT_3306_TCP_ADDR=172.17.0.1
The following will be set on the linked application by default:
DATABASE_URL=mysql://mariadb:SOME_PASSWORD@dokku-mariadb-lollipop:3306/lollipop
The host exposed here only works internally in docker containers. If you want your container to be reachable from outside, you should use the expose
subcommand. Another service can be linked to your app:
dokku mariadb:link other_service playground
It is possible to change the protocol for DATABASE_URL
by setting the environment variable MARIADB_DATABASE_SCHEME
on the app. Doing so will after linking will cause the plugin to think the service is not linked, and we advise you to unlink before proceeding.
dokku config:set playground MARIADB_DATABASE_SCHEME=mysql2
dokku mariadb:link lollipop playground
This will cause DATABASE_URL
to be set as:
mysql2://mariadb:SOME_PASSWORD@dokku-mariadb-lollipop:3306/lollipop
# usage
dokku mariadb:unlink <service> <app>
flags:
-n|--no-restart "false"
: whether or not to restart the app on unlink (default: true)
You can unlink a mariadb service:
NOTE: this will restart your app and unset related environment variables
dokku mariadb:unlink lollipop playground
# usage
dokku mariadb:set <service> <key> <value>
Set the network to attach after the service container is started:
dokku mariadb:set lollipop post-create-network custom-network
Set multiple networks:
dokku mariadb:set lollipop post-create-network custom-network,other-network
Unset the post-create-network value:
dokku mariadb:set lollipop post-create-network
The lifecycle of each service can be managed through the following commands:
# usage
dokku mariadb:connect <service>
Connect to the service via the mariadb connection tool:
NOTE: disconnecting from ssh while running this command may leave zombie processes due to moby/moby#9098
dokku mariadb:connect lollipop
# usage
dokku mariadb:enter <service>
A bash prompt can be opened against a running service. Filesystem changes will not be saved to disk.
NOTE: disconnecting from ssh while running this command may leave zombie processes due to moby/moby#9098
dokku mariadb:enter lollipop
You may also run a command directly against the service. Filesystem changes will not be saved to disk.
dokku mariadb:enter lollipop touch /tmp/test
expose a mariadb service on custom host:port if provided (random port on the 0.0.0.0 interface if otherwise unspecified)
# usage
dokku mariadb:expose <service> <ports...>
Expose the service on the service's normal ports, allowing access to it from the public interface (0.0.0.0
):
dokku mariadb:expose lollipop 3306
Expose the service on the service's normal ports, with the first on a specified ip adddress (127.0.0.1):
dokku mariadb:expose lollipop 127.0.0.1:3306
# usage
dokku mariadb:unexpose <service>
Unexpose the service, removing access to it from the public interface (0.0.0.0
):
dokku mariadb:unexpose lollipop
# usage
dokku mariadb:promote <service> <app>
If you have a mariadb service linked to an app and try to link another mariadb service another link environment variable will be generated automatically:
DOKKU_DATABASE_BLUE_URL=mysql://other_service:ANOTHER_PASSWORD@dokku-mariadb-other-service:3306/other_service
You can promote the new service to be the primary one:
NOTE: this will restart your app
dokku mariadb: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://other_service:ANOTHER_PASSWORD@dokku-mariadb-other-service:3306/other_service
DOKKU_DATABASE_BLUE_URL=mysql://other_service:ANOTHER_PASSWORD@dokku-mariadb-other-service:3306/other_service
DOKKU_DATABASE_SILVER_URL=mysql://lollipop:SOME_PASSWORD@dokku-mariadb-lollipop:3306/lollipop

You can clone an existing service to a new one:
dokku mariadb:clone lollipop lollipop-2
# usage
dokku mariadb:exists <service>
Here we check if the lollipop mariadb service exists.
dokku mariadb:exists lollipop
# usage
dokku mariadb:linked <service> <app>
Here we check if the lollipop mariadb service is linked to the playground
app.
dokku mariadb:linked lollipop playground
# usage
dokku mariadb:links <service>
List all apps linked to the lollipop
mariadb service.
dokku mariadb:links lollipop
The underlying service data can be imported and exported with the following commands:
# usage
dokku mariadb:import <service>
Import a datastore dump:
dokku mariadb:import lollipop < data.dump
# usage
dokku mariadb:export <service>
By default, datastore output is exported to stdout:
dokku mariadb:export lollipop
You can redirect this output to a file:
dokku mariadb:export lollipop > data.dump
Datastore backups are supported via AWS S3 and S3 compatible services like minio.
You may skip the backup-auth
step if your dokku install is running within EC2 and has access to the bucket via an IAM profile. In that case, use the --use-iam
option with the backup
command.
Backups can be performed using the backup commands:
# usage
dokku mariadb:backup-auth <service> <aws-access-key-id> <aws-secret-access-key> <aws-default-region> <aws-signature-version> <endpoint-url>
Setup s3 backup authentication:
dokku mariadb:backup-auth lollipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY
Setup s3 backup authentication with different region:
dokku mariadb:backup-auth lollipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY AWS_REGION
Setup s3 backup authentication with different signature version and endpoint:
dokku mariadb:backup-auth lollipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY AWS_REGION AWS_SIGNATURE_VERSION ENDPOINT_URL
More specific example for minio auth:
dokku mariadb:backup-auth lollipop MINIO_ACCESS_KEY_ID MINIO_SECRET_ACCESS_KEY us-east-1 s3v4 https://YOURMINIOSERVICE
# usage
dokku mariadb:backup-deauth <service>
Remove s3 authentication:

If you wish to disable the docker image pull
calls that the plugin triggers, you may set the MARIADB_DISABLE_PULL
environment variable to true
. Once disabled, you will need to pull the service image you wish to deploy as shown in the stderr
output.
Please ensure the proper images are in place when docker image pull
is disabled.
