# Cassandra Operator workshop
## Requirements
* Kubernetes 1.8+
## Minikube
* [Install](https://kubernetes.io/docs/tasks/tools/install-minikube/)
```
# start
$ minikube start --cpus 4 --memory 4096 --vm-driver hyperkit --kubernetes-version v1.9.4
```
## Deploy Cassandra Operator
Create a deployment for Cassandra Operator
```
$ make deploy-operator
```
Verify the Service was created and a port was allocated:
```
$ kubectl get services
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
cassandra ClusterIP None 9042/TCP 1m
cassandra-seeds ClusterIP None 7000/TCP 1m
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
cassandra-operator-847947679f-sk88d 1/1 Running 0 1m
```
## Provision Cassandra Cluster
Create a deployment for Cassandra Cluster
```
$ make provision-cassandra
```
Example:
```yaml
apiVersion: stable.instaclustr.com/v1
kind: CassandraDataCentre
metadata:
name: cassandra
spec:
serviceName: cassandra
replicas: 1
image: gcr.io/cassandra-operator/cassandra:latest
```
Verify the Pod was created:
```
$ kubectl get pods
NAME READY STATUS RESTARTS AGE
cassandra-0 1/1 Running 0 1m
```
## Tearing down your Operator deployment
```
$ make clean-operator
```
## Cassandra initial setup
### Launch `cqlsh` and execute:
```
$ kubectl exec cassandra-0 -i -t -- bash -c 'cqlsh cassandra-seeds'
$ CREATE KEYSPACE accountsapi WITH replication = {'class': 'SimpleStrategy', 'replication_factor' : 1};
$ use accountsapi; CREATE TABLE accounts (id UUID,name text,age int,email text,city text,PRIMARY KEY (id));
```
## Go client app
### Build
```
$ make docker-app-build
```
### Deploy to mini-kube
```
$ make minikube-deploy
```
Verify the Service was created and a node port was allocated:
```
$ kubectl get service web
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
web NodePort 10.108.82.46 8080:32491/TCP 1h
```
### To run locally, get public API endpoint
```
$ minikube service web --url
http://192.168.64.6:32491
