通过命令安装OpenShift Pipelines Operator
- 用户管理员登录查看operatorhub中的openshift-pipelines-operator
$ oc describe packagemanifest openshift-pipelines-operator -n openshift-marketplace
- 安装OpenShift Pipelines Operator。
$ oc apply -f https://raw.githubusercontent.com/liuxiaoyu-git/learn-katacoda/master/middleware/pipelines/assets/operator/subscription.yaml
- 查看安装后查看和Tekton相关API。
$ oc api-resources --api-group=tekton.dev
NAME SHORTNAMES APIVERSION NAMESPACED KIND
clustertasks tekton.dev/v1beta1 false ClusterTask
conditions tekton.dev/v1alpha1 true Condition
pipelineresources tekton.dev/v1alpha1 true PipelineResource
pipelineruns pr,prs tekton.dev/v1beta1 true PipelineRun
pipelines tekton.dev/v1beta1 true Pipeline
runs tekton.dev/v1alpha1 true Run
taskruns tr,trs tekton.dev/v1beta1 true TaskRun
tasks tekton.dev/v1beta1 true Task
- 安装OpenShift Pipelines Operator后会自动创建openshift-pipelines项目，并在其中运行了以下Pod。
$ oc get pod -n openshift-pipelines

- 查看当前用户已经有以下创建资源的权限。
$ oc auth can-i create pipeline.tekton.dev
$ oc auth can-i create Pipeline
$ oc auth can-i create Task
$ oc auth can-i create PipelineResource
$ oc auth can-i create PipelineRun
创建并运行Tekton Pipeline
- 创建一个lab-tekton项目。
$ oc new-project lab-tekton
- 当安装OpenShift Pipelines Operator后，它会自动为项目创建一个名为pipeline 的ServiceAccount，以拥有build和push镜像的权限。执行命令，验证是否有名为pipeline的ServiceAccount。
$ oc get serviceaccount pipeline -n lab-tekton
NAME SECRETS AGE
pipeline 2 4m11s
- 查看集群中已有的CusterTask对象。
$ oc get clustertask
