使用 gitlab 管道的两个任务定义中的 AWS ECS 图像

AWS ECS images in two task definitions using gitlab pipelines

在设置构建、部署和 运行 docker 映像到 AWS ECS 所需的一切方面,我已经取得了相当大的进步。

到目前为止我已经取得了:

现在的问题: 我正在尝试按照 official gitlab documentation 将映像部署到 ECS。需要说明的是,我使用的是 Fargate,而不是 EC2。我有问题,尤其是 gitlab-ci.yml,因为在文档中,它们指的是应该用于部署的模板。

Template 本身由另外 2 个模板组成:

  1. build template
  2. deploy template

因为我不能按原样依赖这些模板,不仅仅是因为当我按照文档中的描述配置所有内容时它们不起作用,而且主要是因为我有两个任务定义必须在一个 CD 作业中部署.

我已经成功地将部署脚本复制到我自己的 gitlab-ci.yml 文件中。这是当前版本,只有一个任务定义:

stages:
  - test
  - review
  - deploy
  - production
  - cleanup

老实说,我不知道所有这些脚本块(审核、制作...)在做什么。我很高兴收到任何建议,通过 运行 两个任务定义使这个尽可能简单,但也遵循一些最佳实践。

所以我在与 AWS Support 交谈后找到了解决方案,这使这个问题有了更多的了解,但我设法提出了与他们建议的解决方案略有不同的解决方案。

他们的解决方案是注册一个新的任务定义,然后更新服务,这很好,但前提是您确实需要为每个部署作业修改新的任务,而我没有这样做。我使用相同的图片名称和相同的图片标签。

注册新任务定义的版本如下所示:

- aws ecs register-task-definition --cli-input-json $CI_AWS_ECS_TASK_DEFINITION_FILE --family $FAMILY
- aws ecs update-service --cluster $CI_AWS_ECS_CLUSTER --service $CI_AWS_ECS_SERVICE --task-definition $CI_AWS_ECS_TASK_DEFINITION --desired-count 1

此解决方案创建了许多修订并在部署后需要一些清理作业,因此您最终不会有数百个修订。

阅读 AWS 文档,使用 --force-new-deployment.

拉取新映像有一种更简单的方法
deploy:
  image: 'registry.gitlab.com/gitlab-org/cloud-deploy/aws-ecs:latest'
  stage:
    deploy
  environment:
    name: dev
  script:
    - aws ecs update-service --cluster $CI_AWS_ECS_CLUSTER --service $CI_AWS_ECS_SERVICE  --force-new-deployment
