Can someone tell me how to deploy a docker image build with kaniko on gcloud kubernetes cluster using .git-ci.yml file?

Can someone tell me what commands can be written in deploy: stages script tag to push the code on gcloud Kubernetes cluster ?

build:
  stage: build
  image:
    name: gcr.io/kaniko-project/executor:debug
    entrypoint: [""]

  before_script:
    - echo "{\"auths\":{\"$CI_REGISTRY\":{\"username\":\"$CI_REGISTRY_USER\",\"password\":\"$CI_REGISTRY_PASSWORD\"}}}" > /kaniko/.docker/config.json
    - |
      echo "-----BEGIN CERTIFICATE-----
      ...
      -----END CERTIFICATE-----" >> /kaniko/ssl/certs/ca-certificates.crt


  script:
    - echo "{\"auths\":{\"$CI_REGISTRY\":{\"username\":\"$CI_REGISTRY_USER\",\"password\":\"$CI_REGISTRY_PASSWORD\"}}}" > /kaniko/.docker/config.json
    - /kaniko/executor --context $CI_PROJECT_DIR --dockerfile $CI_PROJECT_DIR/Dockerfile --destination $CI_REGISTRY_IMAGE:$CI_COMMIT_TAG
  only:
    - master


deploy:
  stage: deploy

Solution

Here are some articles that have examples about how to write the ‘stage: deploy’ section. They can be used as further guidance through the process. You can refer to deployment section.
