用 DTM Tools 实现基于 GitHub，Argo CD 和 GitHub Actions 的 CICD 流程

DevStream 抽象了2个概念：Tools 和 Apps。

在前一个用户场景 里介绍了 “Apps”，你可以用 “Tools” 实现一样的效果。具体方法如下：

环境变量

你需要先设置如下环境变量：

Bash

  1. export GITHUB_TOKEN="YOUR_GITHUB_TOKEN_HERE"
  2. export IMAGE_REPO_PASSWORD="YOUR_DOCKERHUB_TOKEN_HERE"

配置文件

YAML

  1. config:
  2.   state:
  3.     backend: local
  4.     options:
  5.       stateFile: devstream.state
  7. vars:
  8.   GITHUB_USER: YOUR_GITHUB_USER
  9.   DOCKERHUB_USER: YOUR_DOCKERHUB_USER
  11. tools:
  12. - name: repo-scaffolding
  13.   instanceID: myapp1
  14.   options:
  15.     destinationRepo:
  16.       owner: [[ GITHUB_USER ]]
  17.       name: myapp1
  18.       branch: main
  19.       scmType: github
  20.       token: [[ env GITHUB_TOKEN ]]
  21.     sourceRepo:
  22.       org: devstream-io
  23.       name: dtm-repo-scaffolding-python-flask
  24.       scmType: github
  25. - name: github-actions
  26.   instanceID: flask
  27.   dependsOn: [ repo-scaffolding.myapp1 ]
  28.   options:
  29.     scm:
  30.       owner: [[ GITHUB_USER ]]
  31.       name:  myapp1
  32.       scmType: github
  33.       token: [[ env GITHUB_TOKEN ]]
  34.     pipeline:
  35.       configLocation: https://raw.githubusercontent.com/devstream-io/dtm-pipeline-templates/main/github-actions/workflows/main.yml
  36.       language:
  37.         name: python
  38.         framework: flask
  39.       imageRepo:
  40.         user: [[ DOCKERHUB_USER ]]
  41.         password: [[ env IMAGE_REPO_PASSWORD ]]
  42. - name: helm-installer
  43.   instanceID: argocd
  44. - name: argocdapp
  45.   instanceID: default
  46.   dependsOn: [ "helm-installer.argocd", "github-actions.flask" ]
  47.   options:
  48.     app:
  49.       name: myapp1
  50.       namespace: argocd
  51.     destination:
  52.       server: https://kubernetes.default.svc
  53.       namespace: default
  54.     source:
  55.       valuefile: values.yaml
  56.       path: helm/myapp1
  57.       repoURL: ${{repo-scaffolding.myapp1.outputs.repoURL}}
  58.       token: [[ env GITHUB_TOKEN ]]
  59.     imageRepo:
  60.       user: [[ DOCKERHUB_USER ]]

你需要相应更新上述配置文件里的 “YOUR_GITHUB_USER” 和 “YOUR_DOCKERHUB_USER”。

运行

首先需要初始化：

Bash

  1. # this downloads the required plugins, according to the config file, automatically.
  2. dtm init -f config.yaml

然后运行如下命令让配置生效：

Bash

  1. dtm apply -f config.yaml -y
