• 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

Commands:

• 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

Google Cloud Zone/Region note

--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
