问题描述

我需要在多台服务器上部署我的应用程序.

I need to deploy my application on multiple servers.

我在 gitlab-ci 上托管了我的源代码.我已经设置了环境变量和 .gitlab-ci.yml 文件

I have hosted my source code on gitlab-ci.I have setup envrionnement variables and .gitlab-ci.yml file

它适用于单个服务器:我可以构建 docker 映像并将这些映像推送到注册表.然后我在 kubernetes 基础设施上部署这些图像.所有操作都在 .gitlab-ci.yml 中描述

It works great for a single server: I can build docker images and push this images to a registry.Then i am deploying this images on a kubernetes infrastructure.All operations are described in .gitlab-ci.yml

我需要做的是为每个服务器重复" .gitlab-ci.yml 步骤.我需要为每个服务器设置一组不同的环境变量.(对于我的应用程序的每次升级,我都需要为每台服务器提供一个 docker 映像).

What i need to do is to "repeat" .gitlab-ci.yml steps for each server.I need a different set of envrionment variables for each server. (I will need one docker image for each server, for each upgrade of my application).

有没有办法用 gitlab-ci 做到这一点?

Is there a way to do this with gitlab-ci ?

谢谢

** 编辑 **

这是我的 .gitlab-ci.yml:

Here is my .gitlab-ci.yml:

stages:
  - build
  - deploy

build:
  stage: build
  script:
  - docker image build -t my_ci_registry_url/myimagename .
  - docker login -u "${CI_REGISTRY_USER}" -p "${CI_REGISTRY_PASSWORD}" "${CI_REGISTRY}"
  - docker push my_ci_registry_url/myimagename

deploy:
  stage: deploy
  environment: production
  script:
  - kubectl delete --ignore-not-found=true secret mysecret
  - kubectl create secret docker-registry mysecret --docker-server=$CI_REGISTRY --docker-username=$CI_REGISTRY_USER --docker-password=$CI_REGISTRY_PASSWORD
  - kubectl apply -f myapp.yml
  - kubectl rollout restart deployment/myapp-deployment

推荐答案

为了使用不同的环境变量运行相同的作业,您可以使用 Yaml 锚.

In order to run same job with different environment variables you can use Yaml Anchors.

例如:

stages:
  - build
  - deploy

.deploy: &deploy
  stage: deploy
  environment: production
  script:
  - some use of $SPECIAL_ENV    # from `variables` defined in each job
  - some use of $OTHER_SPECIAL_ENV   # from `variables` defined in each job

build:
  stage: build
  script:
  - ...

deploy env 1:
  variables:
    SPECIAL_ENV: $SPECIAL_ENV_1   # from `CI/CD > Variable`
    OTHER_SPECIAL_ENV: $OTHER_SPECIAL_ENV-1    # from `CI/CD > Variable`
  <<: *deploy

deploy env 2:
  variables:
    SPECIAL_ENV: $SPECIAL_ENV_2   # from `CI/CD > Variable`
    OTHER_SPECIAL_ENV: $OTHER_SPECIAL_ENV_2   # from `CI/CD > Variable`
  <<: *deploy

deploy env 3:
  variables:
    SPECIAL_ENV: $SPECIAL_ENV_3   # from `CI/CD > Variable`
    OTHER_SPECIAL_ENV: $OTHER_SPECIAL_ENV_3   # from `CI/CD > Variable`
  <<: *deploy

这样在 deploy 阶段 3 个作业将运行(并行).
您可以将变量保存在 Settings >CI/CD >变量,如果它们包含敏感数据.如果没有,只需将它们写入您的 .gitlab-ci.yml

That way on deploy stage the 3 jobs will run (parallel).
You can save the variables in Settings > CI/CD > Variable if they contain sensitive data. If not, just write them in your .gitlab-ci.yml
