Google Cloud Platform

AttentionThis page documents an earlier version. Go to the latest (v2.1)version.

Prerequisites

NOTE: If you install gcloud using a package manager (as opposed to downloading and installing it manually), it does not support some of the commands below.

  • Install kubectl

After installing Cloud SDK, install the kubectl command-line tool by running the following command:


1. $ gcloud components install kubectl
  • Configure defaults for gcloud

Set the project id as yugabyte. You can change this as per your need.


1. $ gcloud config set project yugabyte

Set the defaut compute zone as us-west1-b. You can change this as per your need.


1. $ gcloud config set compute/zone us-west1-b

1. Create a GKE cluster

Create a Kubernetes cluster if you have not already done so by running the following command.


1. $ gcloud container clusters create yugabyte

2. Create a YugabyteDB cluster

Create a YugabyteDB cluster by running the following.


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



1. service "yb-masters" created
2. statefulset "yb-master" created
3. service "yb-tservers" created
4. statefulset "yb-tserver" created

3. Check the cluster

You should see the following pods running.


1. $ kubectl get pods



1. NAME           READY     STATUS    RESTARTS   AGE
2. yb-master-0    1/1       Running   0          3m
3. yb-master-1    1/1       Running   0          3m
4. yb-master-2    1/1       Running   0          3m
5. yb-tserver-0   1/1       Running   0          3m
6. yb-tserver-1   1/1       Running   0          3m
7. yb-tserver-2   1/1       Running   0          3m

You can view the persistent volumes.


1. $ kubectl get persistentvolumes



1. NAME                                       CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS    CLAIM                          STORAGECLASS   REASON    AGE
2. pvc-f3301c41-1110-11e8-8231-42010a8a0083   1Gi       RWO            Delete           Bound     default/datadir-yb-master-0    standard                 5m
3. pvc-f33f29b3-1110-11e8-8231-42010a8a0083   1Gi       RWO            Delete           Bound     default/datadir-yb-master-1    standard                 5m
4. pvc-f35005b6-1110-11e8-8231-42010a8a0083   1Gi       RWO            Delete           Bound     default/datadir-yb-master-2    standard                 5m
5. pvc-f36189ab-1110-11e8-8231-42010a8a0083   1Gi       RWO            Delete           Bound     default/datadir-yb-tserver-0   standard                 5m
6. pvc-f366a4af-1110-11e8-8231-42010a8a0083   1Gi       RWO            Delete           Bound     default/datadir-yb-tserver-1   standard                 5m
7. pvc-f36d2892-1110-11e8-8231-42010a8a0083   1Gi       RWO            Delete           Bound     default/datadir-yb-tserver-2   standard                 5m

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


1. $ kubectl get services



1. NAME          TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)                               AGE
2. kubernetes    ClusterIP   XX.XX.XX.X   <none>        443/TCP                               23m
3. yb-masters    ClusterIP   None         <none>        7000/TCP,7100/TCP                     17m
4. yb-tservers   ClusterIP   None         <none>        9000/TCP,9100/TCP,9042/TCP,6379/TCP   14m

4. Connect to the cluster

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


1. $ kubectl exec -it yb-tserver-0 bin/cqlsh



1. Connected to local cluster at 127.0.0.1:9042.
2. [cqlsh 5.0.1 | Cassandra 3.9-SNAPSHOT | CQL spec 3.4.2 | Native protocol v4]
3. Use HELP for help.
4. cqlsh> DESCRIBE KEYSPACES;

6. system_schema  system_auth  system

5. Destroy cluster (optional)

Destroy the YugabyteDB cluster we created above by running the following.


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



1. service "yb-masters" deleted
2. statefulset "yb-master" deleted
3. service "yb-tservers" deleted
4. statefulset "yb-tserver" deleted

To destroy the persistent volume claims (you will lose all the data if you do this), run:


1. $ kubectl delete pvc -l app=yb-master
2. $ kubectl delete pvc -l app=yb-tserver

6. Destroy the GKE cluster (optional)

To destroy the machines we created for the gcloud cluster, run the following.


1. $ gcloud container clusters delete yugabyte
