Google Kubernetes Engine (GKE)

Prerequisites

Before starting deployment, perform the following:

Download and install the Google Cloud SDK.

Note that if you install gcloud using a package manager (as opposed to downloading and installing it manually), some of the commands will not be supported.
Install kubectl command line tool by running the following command:
```
gcloud components install kubectl
```
Configure defaults for gcloud by setting the project ID as yugabyte. You can change this as needed.
```
gcloud config set project yugabyte
```
Set the default compute zone as us-west1-b. You can change this as needed.
```
gcloud config set compute/zone us-west1-b
```

Create a GKE cluster

Create a Kubernetes cluster by running the following command.

gcloud container clusters create yugabyte

Create a YugabyteDB cluster

Create a YugabyteDB cluster by running the following command:

kubectl create -f https://raw.githubusercontent.com/yugabyte/yugabyte-db/master/cloud/kubernetes/yugabyte-statefulset.yaml

service "yb-masters" created
statefulset "yb-master" created
service "yb-tservers" created
statefulset "yb-tserver" created

Check the cluster

Execute the following command to see the pods running:

kubectl get pods

NAME           READY     STATUS    RESTARTS   AGE
yb-master-0    1/1       Running   0          3m
yb-master-1    1/1       Running   0          3m
yb-master-2    1/1       Running   0          3m
yb-tserver-0   1/1       Running   0          3m
yb-tserver-1   1/1       Running   0          3m
yb-tserver-2   1/1       Running   0          3m

You can view the persistent volumes, as follows:

kubectl get persistentvolumes

NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS    CLAIM                          STORAGECLASS   REASON    AGE

You can view all the services by running the following command:

kubectl get services

NAME          TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)                               AGE

Connect to the cluster

You can connect to the YCQL API by running the following:

kubectl exec -it yb-tserver-0 -- ycqlsh yb-tserver-0

Connected to local cluster at 127.0.0.1:9042.

Destroy cluster

Destroy the YugabyteDB cluster you created above by running the following:

kubectl delete -f https://raw.githubusercontent.com/yugabyte/yugabyte-db/master/cloud/kubernetes/yugabyte-statefulset.yaml

service "yb-masters" deleted
statefulset "yb-master" deleted
service "yb-tservers" deleted
statefulset "yb-tserver" deleted

To destroy the persistent volume claims and lose all the data, run the following:

kubectl delete pvc -l app=yb-master
kubectl delete pvc -l app=yb-tserver

Destroy the GKE cluster

To destroy the machines you created for the gcloud cluster, run the following command:

gcloud container clusters delete yugabyte
