1.4. 组装管道

流程

1. 复制以下管道 YAML 文件示例内容并保存：

   apiVersion: tekton.dev/v1
   kind: Pipeline
   metadata:
     name: build-and-deploy
   spec:
     workspaces:
     - name: shared-workspace
     params:
     - name: deployment-name
       type: string
       description: name of the deployment to be patched
     - name: git-url
       type: string
       description: url of the git repo for the code of deployment
     - name: git-revision
       type: string
       description: revision to be used from repo of the code for deployment
       default: "pipelines-1.12"
     - name: IMAGE
       type: string
       description: image to be built from the code
     tasks:
     - name: fetch-repository
       taskRef:
         name: git-clone
         kind: ClusterTask
       workspaces:
       - name: output
         workspace: shared-workspace
       params:
       - name: url
         value: $(params.git-url)
       - name: subdirectory
         value: ""
       - name: deleteExisting
         value: "true"
       - name: revision
         value: $(params.git-revision)
     - name: build-image
       taskRef:
         name: buildah
         kind: ClusterTask
       params:
       - name: IMAGE
         value: $(params.IMAGE)
       workspaces:
       - name: source
         workspace: shared-workspace
       runAfter:
       - fetch-repository
     - name: apply-manifests
       taskRef:
         name: apply-manifests
       workspaces:
       - name: source
         workspace: shared-workspace
       runAfter:
       - build-image
     - name: update-deployment
       taskRef:
         name: update-deployment
       params:
       - name: deployment
         value: $(params.deployment-name)
       - name: IMAGE
         value: $(params.IMAGE)
       runAfter:
       - apply-manifests

   Pipeline 定义提取 Git 源存储库和镜像 registry 的特定内容。当一个管道被触发并执行时，这些详细信息会作为 params 添加。

2. 创建管道：

   $ oc create -f <pipeline-yaml-file-name.yaml>

   或者，还可以从 Git 存储库直接执行 YAML 文件：

   $ oc create -f https://raw.githubusercontent.com/openshift/pipelines-tutorial/pipelines-1.12/01_pipeline/04_pipeline.yaml

3. 使用 tkn pipeline list 命令来验证管道是否已添加到应用程序中：

   $ tkn pipeline list

   检查输出来验证创建了 build-and-deploy pipeline：

   NAME               AGE            LAST RUN   STARTED   DURATION   STATUS
   build-and-deploy   1 minute ago   ---        ---       ---        ---
