      * [new branch] master -> master

      Branch 'master' set up to track remote branch 'master' from 'origin'.

      Now it's time to set up image creation when creating a new version of the product: go to GCP -> Cloud Build -> triggers -> Create trigger -> Google Cloud source code repository -> NodeJS. Trigger tag type so that the image is not created during normal commits. I will change the name of the image from gcr.io/node-cluster-243923/NodeJS:$SHORT_SHA to gcr.io/node-cluster-243923/NodeJS:$SHORT_SHA and the timeout to 60 seconds. Now I'll commit and add a tag:

      essh @ kubernetes-master: ~ / node-cluster / app / nodejs $ cp ../../Dockerfile.

      essh @ kubernetes-master: ~ / node-cluster / app / nodejs $ git add Dockerfile

      essh @ kubernetes-master: ~ / node-cluster / app / nodejs $ git add Dockerfile

      essh @ kubernetes-master: ~ / node-cluster / app / nodejs $ cp ../../Dockerfile.

      * [new tag] v0.0.1 -> v0.0.1

      Now, if we press the start trigger button, we will see the image in the Container Registry with our tag:

      essh @ kubernetes-master: ~ / node-cluster / app / nodejs $ gcloud container images list

      NAME

      gcr.io/node-cluster-243923/nodejs

      gcr.io/node-cluster-243923/nodejs_cluster

      Only listing images in gcr.io/node-cluster-243923. Use –repository to list images in other repositories.

      Now if we just add the changes and the tag, the image will be created automatically:

      essh @ kubernetes-master: ~ / node-cluster / app / nodejs $ sed -i 's / HOSTNAME \} / HOSTNAME \} \ n /' server.js

      essh @ kubernetes-master: ~ / node-cluster / app / nodejs $ git add server.js

      Creating multiple environments with Terraform clusters

      When trying to create several clusters from the same configuration, we will encounter duplicate identifiers that must be unique, so we isolate them from each other by creating and placing them in different projects. To manually create a project, go to GCP -> Products -> IAM and administration -> Resource management and create a NodeJS-prod project and switch to the project, wait for its activation. Let's look at the state of the current project:

      essh @ kubernetes-master: ~ / node-cluster $ cat main.tf

      provider "google" {

      credentials = file ("./ kubernetes_key.json")

      project = "node-cluster-243923"

      region = "europe-west2"

      }

      module "kubernetes" {

      source = "./Kubernetes"

      }

      data "google_client_config" "default" {}

      module "Nginx" {

      source = "./nodejs"

      image = "gcr.io/node-cluster-243923/nodejs_cluster:latest"

      endpoint = module.kubernetes.endpoint

      access_token = data.google_client_config.default.access_token

      cluster_ca_certificate = module.kubernetes.cluster_ca_certificate

      }
