A MariaDB Helm Chart Service Broker for the Kubernetes Service Catalog

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.

Learn more about the Kubernetes Service Catalog

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.
