Knative 初体验：CICD 极速入门

Knative 社区很早就在探讨用 Tekton 替换 Build 模块的事宜。Knative Build 官方已经正式说明不再建议使用 Knative Build 了。

假如你知道 Knative Build 是什么相信你了解起 Tekton 就是很容易的一件事了。

• Knative Build 对自己的一句话概述是：A Kubernetes-native Build resource.
• Tekton 对自己的一句话概述是： A K8s-native Pipeline resource. https://tekton.dev
• 可以看到两者的定位非常相近，而且在功能上 Tekton 的设计更加的丰富、完整，这也是社区最终采用 Tekton 的起因。接下来我们就看一下 Tekton 的核心概念。

Tekton 极速入门

Tekton 主要由如下五个核心概念组成：

• Task
• TaskRun
• Pipeline
• PipelineRun
• PipelineResource
• 这五个概念每一个都是以 CRD 的形式提供服务的，下面分别简述一下这五个概念的含义。

Task

Task 就是一个任务执行模板，之所以说 Task 是一个模板是由于 Task 定义中可以包含变量，Task 在真正执行的时候需要给定变量的具体值。Tekton 的 Task 很相似于一个函数的定义，Task 通过 inputs.params 定义需要哪些入参，并且每一个入参还可以指定默认值。Task 的 steps 字段表示当前 Task 是有哪些子步骤组成的。每一个步骤具体就是一个镜像的执行，镜像的启动参数可以通过 Task 的入参使用模板语法进行配置。

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: tekton.dev/v1alpha1kind: Taskmetadata: name: task-with-parametersspec: inputs: params: - name: flags type: array - name: someURL type: string steps: - name: build image: registry.cn-hangzhou.aliyuncs.com/knative-sample/alpine:3.9 command: ["sh", "-c"] args: [ "echo ${inputs.params.flags} ; echo ${someURL}"]</pre>**TaskRun**

Task 定义好以后是不能执行的，就像一个函数定义好以后需要调用才能执行一样。所以需要再定义一个 TaskRun 去执行 Task。TaskRun 主要是负责设置 Task 需要的参数，并通过 taskRef 字段引用要执行的 Task。

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: tekton.dev/v1alpha1kind: TaskRunmetadata: name: run-with-parametersspec: taskRef: name: task-with-parameters inputs: params: - name: flags value: "--set" - name: someURL value: " knative-sample"</pre>**Pipeline**

一个 TaskRun 只能执行一个 Task，当需要编排多个 Task 的时候就需要 Pipeline 出马了。Pipeline 是一个编排 Task 的模板。Pipeline 的 params 公告了执行时需要的入参。 Pipeline 的 spec.tasks 定义了需要编排的 Task。Tasks 是一个数组，数组中的 task 并不是通过数组公告的顺序去执行的，而是通过 runAfter 来公告 task 执行的顺序。Tekton controller 在解析 CRD 的时候会解析 Task 的顺序，而后依据设定的顺序依次去执行。Pipeline 在编排 Task 的时候需要给每一个 Task 传入必需的参数，这些参数的值可以来自 Pipeline 自身的 params。

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: tekton.dev/v1alpha1kind: Pipelinemetadata: name: pipeline-with-parametersspec: params: - name: context type: string description: Path to context default: /some/where/or/other tasks: - name: task-1 taskRef: name: build params: - name: pathToDockerFile value: Dockerfile - name: pathToContext value: "${params.context}" - name: task-2 taskRef: name: build-push runAfter: - source-to-image params: - name: pathToDockerFile value: Dockerfile - name: pathToContext value: "${params.context}"</pre>

PipelineRun

和 Task 一样 Pipeline 定义完成以后也是不能直接执行的，需要 PipelineRun 才能执行 Pipeline。PipelineRun 的主要作用是给 Pipeline 设定必要的入参，并执行 Pipeline。

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: tekton.dev/v1alpha1kind: PipelineRunmetadata: name: pipelinerun-with-parametersspec: pipelineRef: name: pipeline-with-parameters params: - name: "context" value: "/workspace/examples/microservices/leeroy-web"</pre>

PipelineResource

前面已经详情了 Tekton 的四个核心概念。现在我们已经知道怎样定义 task、执行 task 以及编排 task 了。但可能你还想在 Task 之间共享资源，这就是 PipelineResource 的作用。比方我们可以把 git 仓库信息放在 PipelineResource 中。这样所有 Pipeline 即可以共享这份数据了。

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">piVersion: tekton.dev/v1alpha1kind: PipelineResourcemetadata: name: wizzbang-git namespace: defaultspec: type: git params: - name: url value:  wizzbangcorp/wizzbang.git - name: revision value: master</pre>

受权信息

git 仓库、镜像仓库这些都是需要鉴权才能使用的。所以还需要一种设定鉴权信息的机制。Tekton 本身是 Kubernetes 原生的编排系统。所以可以直接使用 Kubernetes 的 ServiceAccount 机制实现鉴权。

实例如下：

• 定义一个保存镜像仓库鉴权信息的 secret

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: v1kind: Secretmetadata: name: ack-cr-push-secret annotations: tekton.dev/docker-0: https://registry.cn-hangzhou.aliyuncs.comtype: kubernetes.io/basic-authstringData: username: <cleartext non-encoded> password: <cleartext non-encoded></pre>

• 定义 ServiceAccount ，并且使用上面的 secret

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: v1kind: ServiceAccountmetadata: name: pipeline-accountsecrets:- name: ack-cr-push-secret</pre>

• PipelineRun 中引用 ServiceAccount

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: tekton.dev/v1alpha1kind: PipelineRunmetadata: generateName: tekton-kn-sample-spec: pipelineRef: name: build-and-deploy-pipeline... ... serviceAccount: pipeline-account</pre>

Hello World

knative-sample/tekton-knative 这是一个完整的 Tekton 的 Helle World。下面我们一起体验一下这个 Helle World。

在开始实战之前你需要有一个 Kubernetes 集群，并还需要安装 Knative 和 Tekton。tekton-knative 中的 release-v0.5.2.yaml 直接提交到 Kubernetes 集群就可完成 Tekton 的安装。下面我们开始体验使用 Tekton 从源码到构建再到部署的自动化过程。

clone 代码

clone 代码到本地。

git clone knative-sample/tekton-knative

创立 PipelineResource

主要内容在 resources/picalc-git.yaml 文件中。如下所示主要是把 knative-sample/tekton-knative 保存在 resource 中给其余资源使用。

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: tekton.dev/v1alpha1kind: PipelineResourcemetadata: name: tekton-knative-gitspec: type: git params: - name: revision value: master - name: url value:  knative-sample/tekton-knative</pre>

创立 task

创立 task，这个例子中我们创立两个 task：source-to-image 和 deploy-using-kubectl

• source-to-image
• 主要内容在 tasks/source-to-image.yaml 文件中。此 task 的主要功能是把源代码编译成镜像。

主要是使用 kaniko 实现容器内编译 Docker 镜像的能力。此 Task 的参数主要是设置编译上下文的少量信息，比方：Dockerfile、ContextPath 以及目标镜像 tag 等。

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: tekton.dev/v1alpha1kind: Taskmetadata: name: source-to-imagespec: inputs: resources: - name: git-source type: git params: - name: pathToContext description: The path to the build context, used by Kaniko - within the workspace default: . - name: pathToDockerFile description: The path to the dockerfile to build (relative to the context) default: Dockerfile - name: imageUrl description: Url of image repository - name: imageTag description: Tag to apply to the built image default: "latest" steps: - name: build-and-push image: registry.cn-hangzhou.aliyuncs.com/knative-sample/kaniko-project-executor:v0.10.0 command: - /kaniko/executor args: - --dockerfile=${inputs.params.pathToDockerFile} - --destination=${inputs.params.imageUrl}:${inputs.params.imageTag} - --context=/workspace/git-source/${inputs.params.pathToContext} env: - name: DOCKER_CONFIG value: /builder/home/.docker</pre>

• deploy-using-kubectl
• 主要内容在 tasks/deploy-using-kubectl.yaml 文件中。

如下所示这个 Task 主要的作用是通过参数获取到目标镜像的信息，而后执行一条 sed 命令把 Knative Service yaml 中的 IMAGE 替换成目标镜像。再通过 kubectl 发布到 Kubernetes 中。

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: tekton.dev/v1alpha1kind: Taskmetadata: name: deploy-using-kubectlspec: inputs: resources: - name: git-source type: git params: - name: pathToYamlFile description: The path to the yaml file to deploy within the git source - name: imageUrl description: Url of image repository - name: imageTag description: Tag of the images to be used. default: "latest" steps: - name: update-yaml image: alpine command: ["sed"] args: - "-i" - "-e" - "s;__IMAGE__;${inputs.params.imageUrl}:${inputs.params.imageTag};g" - "/workspace/git-source/${inputs.params.pathToYamlFile}" - name: run-kubectl image: registry.cn-hangzhou.aliyuncs.com/knative-sample/kubectl:v0.5.0 command: ["kubectl"] args: - "apply" - "-f" - "/workspace/git-source/${inputs.params.pathToYamlFile}"</pre>

定义 Pipeline

现在我们已经有两个 Task 了，现在我们就用一个 PIpeline 来编排这两个 Task：

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: tekton.dev/v1alpha1kind: Pipelinemetadata: name: build-and-deploy-pipelinespec: resources: - name: git-source type: git params: - name: pathToContext description: The path to the build context, used by Kaniko - within the workspace default: src - name: pathToYamlFile description: The path to the yaml file to deploy within the git source - name: imageUrl description: Url of image repository - name: imageTag description: Tag to apply to the built image tasks: - name: source-to-image taskRef: name: source-to-image params: - name: pathToContext value: "${params.pathToContext}" - name: imageUrl value: "${params.imageUrl}" - name: imageTag value: "${params.imageTag}" resources: inputs: - name: git-source resource: git-source - name: deploy-to-cluster taskRef: name: deploy-using-kubectl runAfter: - source-to-image params: - name: pathToYamlFile value: "${params.pathToYamlFile}" - name: imageUrl value: "${params.imageUrl}" - name: imageTag value: "${params.imageTag}" resources: inputs: - name: git-source resource: git-source</pre>

鉴权信息

如下所示，定义一个 Secret 和 ServiceAccount。并且给 ServiceAccount 绑定执行 Knative Service 的权限。

首先创立一个 Secret 保存镜像仓库的鉴权信息，如下所示:

• tekton.dev/docker-0 换成你要推送的镜像仓库的地址
• username 换成镜像仓库鉴权的客户名
• password 环境镜像仓库鉴权的密码

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: v1kind: Secretmetadata: name: ack-cr-push-secret annotations: tekton.dev/docker-0: https://registry.cn-hangzhou.aliyuncs.comtype: kubernetes.io/basic-authstringData: username: <cleartext non-encoded> password: <cleartext non-encoded></pre>

下面这些信息保存到文件中，而后使用 kubectl apply -f 指令提交到 Kubernetes

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">---apiVersion: v1kind: ServiceAccountmetadata: name: pipeline-accountsecrets:- name: ack-cr-push-secret---apiVersion: v1kind: Secretmetadata: name: kube-api-secret annotations: kubernetes.io/service-account.name: pipeline-accounttype: kubernetes.io/service-account-token---kind: RoleapiVersion: rbac.authorization.k8s.io/v1metadata: name: pipeline-rolerules:- apiGroups: ["serving.knative.dev"] resources: ["services"] verbs: ["get", "create", "update", "patch"]---apiVersion: rbac.authorization.k8s.io/v1kind: RoleBindingmetadata: name: pipeline-role-bindingroleRef: apiGroup: rbac.authorization.k8s.io kind: Role name: pipeline-rolesubjects:- kind: ServiceAccount name: pipeline-account</pre>

定义 PIpelineRun

ServiceAccount 对应的鉴权信息是通过和 PIpelineRun 绑定的方式执行的。参见 run/picalc-pipeline-run.yaml 文件

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">apiVersion: tekton.dev/v1alpha1kind: PipelineRunmetadata: generateName: tekton-kn-sample-spec: pipelineRef: name: build-and-deploy-pipeline resources: - name: git-source resourceRef: name: tekton-knative-git params: - name: pathToContext value: "src" - name: pathToYamlFile value: "knative/helloworld-go.yaml" - name: imageUrl value: "registry.cn-hangzhou.aliyuncs.com/knative-sample/tekton-knative-helloworld" - name: imageTag value: "1.0" trigger: type: manual serviceAccount: pipeline-account</pre>

执行 HelloWorld

准备 PIpeline 的资源

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">kubectl apply -f tasks/source-to-image.yaml -f tasks/deploy-using-kubectl.yaml -f resources/picalc-git.yaml -f image-secret.yaml -f pipeline-account.yaml -f pipeline/build-and-deploy-pipeline.yaml </pre>

执行 create 把 pipelieRun 提交到 Kubernetes 集群。之所以这里使用 create 而不是使用 apply 是由于 PIpelineRun 每次都会创立一个新的，kubectl 的 create 指令会基于 generateName 创立新的 PIpelineRun 资源。

<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">kubectl create -f run/picalc-pipeline-run.yaml </pre>查看一下 pod 信息可能是下面这样：<pre style="-webkit-tap-highlight-color: transparent; box-sizing: border-box; font-family: Consolas, Menlo, Courier, monospace; font-size: 16px; white-space: pre-wrap; position: relative; line-height: 1.5; color: rgb(153, 153, 153); margin: 1em 0px; padding: 12px 10px; background: rgb(244, 245, 246); border: 1px solid rgb(232, 232, 232); font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">└─# kubectl get podNAME READY STATUS RESTARTS AGEtekton-kn-sample-45d84-deploy-to-cluster-wfrzx-pod-f093ef 0/3 Completed 0 8htekton-kn-sample-45d84-source-to-image-7zpqn-pod-c2d20c 0/2 Completed 0 8h</pre>
