bitbucket - 有没有一种方法可以在bitbucket管道中缓存DockerHub镜像？

Question

我正在使用来自dockerhub的外部docker镜像。

在每个步骤中，一次又一次地将dockerimage从dockerhub中拉出。是的，这是理想的工作流程。

我的问题是我们可以缓存该镜像，以便它在每个步骤中都不会从dockerhub中拉出吗？此DockerImage不会频繁更改，因为它仅预安装了节点和 meteor 。

那么有可能缓存docker镜像吗？

原始bitbucket-pipeline.yml

image: tasktrain/node-meteor-mup

pipelines:
  branches:
    '{develop}':
      - step:
          name: "Client: Install Dependencies"
          caches:
            - node
          script:
            - npm install
            - npm run setup-meteor-client-bundle
          artifacts:
            - node_modules/**
      - step:
          name: "Client: Build for Staging"
          script:
            - npm run build-browser:stag
          artifacts:
            - dist/**
      - step:
          name: "Client: Deploy to Staging"
          deployment: staging
          script:
            - pipe: atlassian/aws-s3-deploy:0.2.2
              variables:
                AWS_ACCESS_KEY_ID: $AWS_ACCESS_KEY_ID
                AWS_SECRET_ACCESS_KEY: $AWS_SECRET_ACCESS_KEY
                AWS_DEFAULT_REGION: $AWS_DEFAULT_REGION
                S3_BUCKET: $S3_STAGING_BUCKET_NAME
                LOCAL_PATH: 'dist'
                ACL: "public-read"
                DELETE_FLAG: "true"
                EXTRA_ARGS: "--follow-symlinks --quiet"
      - step:
          name: "Server: Build and Deploy to Staging"
          script:
            - cd server
            - mup setup --config=.deploy/mup-settings.stag.js
            - mup deploy --config=.deploy/mup-settings.stag.js --settings=meteor-settings.stag.json

确实可以缓存依赖项，而docker是Bitbucket Pipelines的pre-defined caches之一

pipelines:
  default:
    - step:
        services:
          - docker
        caches:
          - docker
        script:
          - docker pull my-own-repository:5000/my-image
