To install and kubectl, perform the following steps:
Install the Cloud SDK, which includes the gcloud command-line tool.
Install the kubectl command-line tool
$ gcloud components install kubectl
Configure default settings
Here we set the project id that will be the home for our Kubernetes nodes and the primary geographic zone for the cluster.
PROJECT_ID=beaconchain
CLUSTER_NAME=cardano
CLUSTER_ZONE=us-central1-a
# Setting a default project ID
$ gcloud config set project $PROJECT_ID
# Setting a default compute zone or region
$ gcloud config set compute/zone $CLUSTER_ZONE
Creating a GKE cluster
$ gcloud container clusters create $CLUSTER_NAME \
--disk-size=32GB \
--machine-type=e2-medium \
--node-locations=$CLUSTER_ZONE \
--zone=$CLUSTER_ZONE \
--num-nodes=2
Creating cluster cardano in us-central1-a... Cluster is being health-checked (master is healthy)...done.
NAME LOCATION MASTER_VERSION MASTER_IP MACHINE_TYPE NODE_VERSION NUM_NODES STATUS
cardano us-central1-a 1.18.12-gke.1210 34.123.140.191 e2-medium 1.18.12-gke.1210 2 RUNNING
Great, to install Kubernetes on two nodes and network them together to form a cluster took about 1min.
Get credentials for the cluster
$ gcloud container clusters get-credentials $CLUSTER_NAME
Fetching cluster endpoint and auth data.
kubeconfig entry generated for cardano.
We should now be able to use the kubectl command
$ kubectl cluster-info
