Tekton CICD demo 1

本例是第一步，使用 git 下载代码，并且 提取 commitid

既然是从git下载代码，那么首先就要创建 git resource

apiVersion: tekton.dev/v1alpha1
kind: PipelineResource
metadata:
  name: tektongolang-git
  namespace: lizhe
spec:
  type: git
  params:
    - name: revision
      value: master
    - name: url
      value: https://github.com/zl86790/tektongolang.git

然后我们创建 git 仓库的权限

apiVersion: v1
kind: Secret
metadata:
  name: git-secret
  namespace: lizhe
  annotations:
    tekton.dev/git-0: https://github.com # Described below
type: kubernetes.io/basic-auth
stringData:
  username: <cleartext username>
  password: <cleartext password>

因为下面我们会使用一个私有docker镜像，所以这里再创建一个docker权限

kubectl create secret docker-registry docker-secret -n lizhe \
                    --docker-server=https://index.docker.io/v1/ \
                    --docker-username=<your-name> \
                    --docker-password=<your-pword> \
                    --docker-email=<your-email>

创建一个 service account，并且附加上刚刚创建的 git-secret 和docker-secret

apiVersion: v1
kind: ServiceAccount
metadata:
  name: build-bot-sa
  namespace: lizhe
secrets:
  - name: git-secret
  - name: docker-secret

然后我们创建一个 getcommitid 的 task

这个task使用的 image 是 getcommitid.sh

touch /$1/commitid.txt
git -C /$1 rev-parse HEAD > /$1/commitid.txt
ls /$1
cat /$1/commitid.txt

创建task

apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
  name: get-commitid
  namespace: lizhe
spec:
  resources:
    inputs:
      - name: git-source
        type: git
  steps:
    - name: get-commitid
      image: libaibai/gitcid
      env:
        - name: "DOCKER_CONFIG"
          value: "/tekton/home/.docker/"
      command: ["/bin/bash", "-c", "/getcommitid.sh /workspace/git-source"]

尝试启动这个task
