Installation and Usage for Kubernetes

PREREQUISITES:

  • Kubernetes is up and running
  • The service catalog is deployed on Kubernetes

Deploy and configure a mongodb server

Example using helm chart from here: https://github.com/kubernetes/charts/tree/master/stable/mongodb

  1. Deploy the mongodb server using helm. You can also configure a DB instance in this step but it is not needed.
helm install --name mongodb --set mongodbRootPassword=password charts/mongodb

  1. Verify that the pod is started in Kubernetes UI and there are no errors.

  2. Log into the mongo database server

sudo docker run -it --rm bitnami/mongodb mongo --host 172.17.0.7 admin -u root -p password

Create an account on the database server for the service broker

  1. Connect to the database server
  2. Add the user that will create databases
use admin
db.createUser({ user: 'admin', pwd: 'password', roles: [{"role" : "readWriteAnyDatabase","db" : "admin"},{"role" : "userAdminAnyDatabase","db" : "admin"}] });

Deploy the mongodb-service-broker into Kubernetes

  1. Install the mongodb-service-broker into kubernetes
helm install charts/service-broker-mongodb --name service-broker-mongodb --namespace default

  1. Verify that the pod is started in kubernetes UI

  2. Verify Successful installation of the broker

  • a. list out all of the brokers and classes. It may take a few minutes, but there should be two entries, one for the broker, and one for the service class
kubectl get clusterservicebrokers,clusterserviceclasses
  • b. If the service class doesn't show up, look at the error message
kubectl get clusterservicebrokers mongodb-service-broker -o yaml

4, Show the plans

kubectl get clusterserviceplans -o=custom-columns=NAME:.metadata.name,EXTERNAL\ NAME:.spec.externalName

Provisioning a new DB instance using the service catalog

kubectl create -f charts/service-broker-mongodb/mongodb-service-instance.yaml

Binding the DB to a service

kubectl create -f charts/service-broker-mongodb/mongodb-service-binding.yaml
