Use Codefresh GKE plugin to create GKE Kubernetes cluster for integration tests

• set GOOGLE_SERVICE_ACCOUNT_KEY to the Google Service Account Key value
• Service account should have enough permissions to create and operate GKE Cluster: Kubernetes Engine Admin or subset of privileges from GKE Developer+clusterAdmin

• GOOGLE_SERVICE_ACCOUNT_KEY - Google Service Account Key value, mandatory

• CLOUDSDK_COMPUTE_ZONE - one of valid Google Compute zones - see https://cloud.google.com/compute/docs/regions-zones/

• CLOUDSDK_COMPUTE_REGION - one of valid Google Compute regions. If both CLOUDSDK_COMPUTE_ZONE and CLOUDSDK_COMPUTE_REGION are not set, default is us-central1

• GKE_CLUSTER_NAME - name of gke cluster to create

• Codefresh variables: https://docs.codefresh.io/docs/variables

• gke-create - creates GKE cluster on Google Cloud project defined by GOOGLE_SERVICE_ACCOUNT_KEY

  • gcloud container clusters create <GKE_CLUSTER_NAME> <optional parameters>
  • sets kubectl current context to the newly created cluster for futher pipeline steps

• gke-delete - deletes GKE Cluster by name on Google Cloud project defined by GOOGLE_SERVICE_ACCOUNT_KEY

• kubectl - you can use it to operate on the created cluster

• gcloud

--zone=<zone> or --region=<region> parameters are mandatory for gcloud container clusters ... commands By default we are using default zone of us-central1 region You can change it by specifying yours --zone= | --region= or using CLOUDSDK_COMPUTE_ZONE | CLOUDSDK_COMPUTE_ZONE env vars If you specified --zone= | --region= for gke-create you must specify the same zone/region parameters for gke-delete

Set the environment variables and add the following step to your Codefresh pipeline:

---
version: '1.0'

steps:
  # 
  create-cluster:
    image: codefreshplugins/plugin-gke
    commands: 
        - gke-create gke-test-cluster-1 --zone=us-central1-a --num-nodes 2 --machine-type n1-standard-2
    
  deploy-my-service:
    image: codefreshplugins/plugin-gke
    commands:
        - kubectl get pods --all-namespaces -owide
       # - deploy.sh
       # - kubectl run --image mytestimage
       # - check-status.sh

  clean:
     image: codefreshplugins/plugin-gke
     commands:
        - gke-delete gke-test-cluster-1 --zone=us-central1-a
