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 private Kubernetes cluster using the following command.

gcloud container clusters create cluster_name --enable-private-nodes

Note that you must set up Cloud NAT for a private Kubernetes cluster in Google Cloud to ensure that your cluster can access the internet while its nodes do not have public IP addresses. Refer to Configuring Private Google Access and Cloud NAT in Google Cloud Platform (GCP).

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
