AWS Lambda 基于GitLab的简易CI/CD (Python版本)

此CI/CD配置文件无法直接创建lambda,可以在lambda创建后实现：

• 代码更新
• 版本发布
• 切换别名

Runner 需要安装如下库:

• aws cli
• python3.9
• zip
• jq

.gitlab-ci.yml

stages:
    - archiving
    - deploy
    - publishVersion
    - updateAlias


archive:
    stage: archiving
    script:
        - python3.9 --version
        - python3.9 -m pip install -r requirements.txt  --target=.
        - zip -r $CI_PROJECT_NAME.zip * -x .gitlab-ci.yml README.md requirements.txt
    artifacts:
        paths:
        - $CI_PROJECT_NAME.zip
    only:
        - tags

deploy:
    stage: deploy
    script:
        - aws --version
        - aws lambda update-function-code --function-name $CI_PROJECT_NAME --zip-file fileb://$CI_PROJECT_NAME.zip
        - sleep 30s
    only:
        - tags

publishVersion:
    stage: publishVersion
    script:
        - echo `aws lambda publish-version --function-name $CI_PROJECT_NAME --description $CI_COMMIT_TAG | jq -r .Version` > version
        - sleep 5s
    artifacts:
        paths:
        - version
    only:
        - tags


updateAlias:
    stage: updateAlias
    script:
        - aws lambda update-alias --function-name $CI_PROJECT_NAME --name prod --function-version $(cat version)
    only:
        - tags
