Docker 如何制作使用gitlab ci构建的最新映像；最新的；？

我有一个spring boot with jib项目，其中构建的最新Docker映像具有“最新”标签。现在我已经为我的angular项目创建了Dockerfile和管道定义，但是没有创建最新的标记。如何使最新的映像自动成为最新的，就像我的springbootjib项目一样

我的Dockerfile：

FROM nginx:latest
COPY dist/test-docker-angular-app/ /usr/share/nginx/html
COPY nginx.conf /etc/nginx/nginx.conf

My gitlab-ci.yml：

stages:
  - build
  - package

variables:
  VERSION: ${CI_COMMIT_SHORT_SHA}-${CI_COMMIT_REF_SLUG}

build-prod-app:
  stage: build
  image: node:latest
  script:
    - npm install -g @angular/cli@9.1.0
    - npm install
    - ng build --prod
  artifacts:
    paths:
      - dist/
    expire_in: 2 hours
  cache:
    paths:
      - node_modules/
docker-build:
  image: docker:stable
  stage: package
  services:
    - docker:dind
  before_script:
    - echo $CI_BUILD_TOKEN | docker login -u "$CI_REGISTRY_USER"
      --password-stdin $CI_REGISTRY
  script:
    - IMAGE_NAME="$CI_REGISTRY_IMAGE:$VERSION"
    - docker build --pull -t "$IMAGE_NAME" -f Dockerfile .
    - docker push "$IMAGE_NAME"

---

这对我起了作用：

docker-build-master:
  image: docker:stable
  stage: package
  services:
    - docker:dind
  before_script:
    - docker login -u "$CI_REGISTRY_USER" -p "$CI_REGISTRY_PASSWORD" $CI_REGISTRY
  script:
    - docker build --pull -t "$CI_REGISTRY_IMAGE" .
    - docker push "$CI_REGISTRY_IMAGE"
  only:
    - master

docker-build:
  image: docker:stable
  stage: package
  services:
    - docker:dind
  before_script:
    - docker login -u "$CI_REGISTRY_USER" -p "$CI_REGISTRY_PASSWORD" $CI_REGISTRY
  script:
    - IMAGE_NAME="$CI_REGISTRY_IMAGE:$VERSION"
    - docker build --pull -t "$IMAGE_NAME" .
    - docker push "$IMAGE_NAME"
  except:
    - master
