使用github actions CICD到aws的ecs服务

使用github actions CICD to aws ecs服务

本文记录从头搭建一个简单web后端环境配置gihub actions到最终运行至aws ecs集群。

参考文档：

1. github actions官方文档
2. aws ecs搭建官方文档
3. aws task definition参数官方文档

Step 1 本地项目配置

1. 新建一个spring项目，并添加一个心跳接口用以校验服务是否正常启动。
   

2. 根据github官方文档中提供的demo示例添加workflow文件,因为github actions会自动扫描./github/workflows/目录下的workflow文件，所以命名随意，我这里命名未CICD.yml。以下是CICD.yml内容。
   文件中的on:触发操作需要按照自己项目需求修改，文件中的env配置信息需要按照自己项目需求修改

# This workflow uses actions that are not certified by GitHub.
# They are provided by a third-party and are governed by
# separate terms of service, privacy policy, and support
# documentation.

# GitHub recommends pinning actions to a commit SHA.
# To get a newer version, you will need to update the SHA.
# You can also reference a tag or branch, but the action may change without warning.

name: Deploy to Amazon ECS

on:
  push:
    branches:
      - yourBranch                     # push to yourBranch will toggle this workflow

env:
  AWS_REGION: yourAwsRegion                 # set this to your preferred AWS region, e.g. us-west-1
  ECR_REPOSITORY: yourEcrRepository           # set this to your Amazon ECR repository name
  ECS_SERVICE: yourEcsService                 # set this to your Amazon ECS service name
  ECS_CLUSTER: yourEcsCluster                 # set this to your Amazon ECS cluster name
  ECS_TASK_DEFINITION: yourTaskDefinitionFileName # set this to the path to your Amazon ECS task definition
  # file, e.g. task-definition.json
  CONTAINER_NAME: yourContainerName
  # set this to the name of the container in the
  # containerDefinitions section of your task definition
