Setup Kubernetes Cluster On GCP Using KOPS

1. Download binaries

   curl -Lo kops https://github.com/kubernetes/kops/releases/download/$(curl -s https://api.github.com/repos/kubernetes/kops/releases/latest | grep tag_name | cut -d '"' -f 4)/kops-linux-amd64

2. Give permission to KOPSpackage using:

   chmod +x ./kops

3. Copy KOPS using:

   sudo mv ./kops /usr/local/bin/

1. Download kubectl using:

   curl -Lo kubectl https://storage.googleapis.com/kubernetes-release/release/$(curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt)/bin/linux/amd64/kubectl

2. Give permission to kubectl package using:

   chmod +x ./kubectl

3. Copy kubectl using:

   sudo mv ./kubectl /usr/local/bin/kubectl

1. kops needs a state store, to hold the configuration for your clusters. The simplest configuration for Google Cloud is to store it in a Google Cloud Storage bucket in the same account, so that’s how we’ll start. So, just create an empty bucket – you can use any (available) name

   gsutil mb gs://<Name of your choice>

2. Further, rather than typing the –state argument every time, it’s much easier to export the KOPS_STATE_STORE environment variable:

   export KOPS_STATE_STORE=gs://<Name of bucket defined in step 1>

ssh-keygen

1. Lets first set a project in Cloud Shell:

   PROJECT=`gcloud config get-value project`

2. To unlock the GCE features

   export KOPS_FEATURE_FLAGS=AlphaAllowGCE

3. kops create cluster creates the Cluster object and InstanceGroup object you’ll be working with in kops:

   kops create cluster simple.k8s.local --zones us-central1-a --state ${KOPS_STATE_STORE}/ --project=${PROJECT}

4. You can now list the Cluster objects in your kops state store

   kops get cluster --state ${KOPS_STATE_STORE}

5. Starting it all

   kops update cluster simple.k8s.local --yes

kops delete cluster simple.k8s.local --yes
