Codefresh GKE plugin

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

codefresh/plugin-gke Docker Image details

Requirements:

  • 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

Environements:

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

Usage

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
