MariaDB Broker

This is an implementation of a Service Broker that uses Helm to provision instances of MariaDB. This is a proof-of-concept for the Kubernetes Service Catalog, and should not be used in production.

Prerequisites

  1. Kubernetes cluster (minikube)
  2. Helm 2.x
  3. Service Catalog API - follow the walkthrough

Installing the Broker

The MariaDB Service Broker can be installed using the Helm chart in this repository.

$ git clone https://github.com/prydonius/mariadb-broker.git
$ cd mariadb-broker
$ helm install --name mariadb-broker --namespace mariadb-broker charts/mariadb-broker

To register the Broker with the Service Catalog, create the Broker object:

$ kubectl --context service-catalog create -f examples/mariadb-broker.yaml

If the Broker was successfully registered, the mariadb ServiceClass will now be available in the catalog:

$ kubectl --context service-catalog get serviceclasses
NAME      KIND
mariadb   ServiceClass.v1alpha1.servicecatalog.k8s.io

Usage

Create the Instance object

$ kubectl --context service-catalog create -f examples/mariadb-instance.yaml

This will result in the installation of a new MariaDB chart:

$ helm list
NAME                                  	REVISION	UPDATED                 	STATUS  	CHART               	NAMESPACE
i-3e0e9973-a072-49ba-8308-19568e7f4669	1       	Sat May 13 17:28:35 2017	DEPLOYED	mariadb-0.6.1       	3e0e9973-a072-49ba-8308-19568e7f4669

Create a Binding to fetch credentials

$ kubectl --context service-catalog create -f examples/mariadb-binding.yaml

A secret called mariadb-instance-credentials will be created containing the connection details for this MariaDB instance.

$ kubectl get secret mariadb-instance-credentials -o yaml

Consume connection details in an application

examples/wordpress.yaml is an example of an application definition consuming the database credentials from the secret generated by the MariaDB Broker.

$ kubectl create -f examples/wordpress.yaml

Access the Service via the LoadBalancer IP or NodePort in your browser.
