Tekton CICD demo 3
上一章中我们使用task2正确输出了 task1 生成的 commitid
这一章我要添加一个 step，用来在task2中构建docker image，为了使用 commit.txt 这次我们不直接mount，而是重新编写一个 kaniko的启动脚本
因为添加了一个新的 output 所以pipeline 和 task 都需要修改
- 添加docker resource
docker_resource.yaml
apiVersion: tekton.dev/v1alpha1
kind: PipelineResource
metadata:
name: tektongolang-image
namespace: lizhe
spec:
type: image
params:
- name: url
value: libaibai/tektongolang
2. 创建一个新的 kaniko
exec.sh
此脚本接收4个参数分别是
- $1 dockerfile
- $2 docker context path
- $3 docker destination
- $4 commitid.txt path
set -e
if [ $# -lt 4 ]; then
echo "Usage: <path to Dockerfile> <context directory> <docker_url> <commitid_path>"
exit 1
fi
dockerfile=$1
context=$2
destination=$3
commitid=`cat $4`
echo "building start..."
echo "commitid:"${commitid}
/kaniko/executor --dockerfile=$dockerfile \
--destination=$destination:$commitid \
--context=$contextDockerfile
FROM gcr.io/kaniko-project/executor:debug
COPY exec.sh /exec.sh
CMD [ "/busybox/sh" ]3. 修改 build img task
build_img_task.yaml
apiVersion: tekton.dev/v1beta1
kind: Task
metadata:
name: build-img
namespace: lizhe
spec:
resources:
outputs:
- name: builtImage
type: image
steps:
- name: echo-commitid
image: ubuntu
command: ["/bin/bash", "-c", "cat /workspace/git-source/commitid.txt"]
- name: build-image-with-commitid-and-push
image: libaibai/kanikocid:latest
env:
- name: "DOCKER_CONFIG"
value: "/tekton/home/.docker/"
command: ["/busybox/sh", "-c", "/exec.sh Dockerfile /workspace/git-source $(resources.outputs.builtImage.url) /workspace/git-source/commitid.txt"]
workspaces:
- name: build-workspace
description: |
The folder where will be shared among the tasks
optional: false
mountPath: /workspace
4. 修改pipeline
pipeline_demo.yaml
apiVersion: tekton.dev/v1beta1
kind: Pipeline
metadata:
name: pipeline-demo
namespace: lizhe
spec:
resources:
- name: source-repo
type: git
- name: tektongolang-image
type: image
workspaces:
- name: build-workspace
optional: false
tasks:
- name: git-commitid
taskRef:
name: get-commitid
resources:
inputs:
- name: git-source
resource: source-repo
workspaces:
- name: build-workspace
workspace: build-workspace
- name: build-img
runAfter: [git-commitid]
taskRef:
name: build-img
resources:
outputs:
- name: builtImage
resource: tektongolang-image
workspaces:
- name: build-workspace
workspace: build-workspace
5. 修改pipeline run
pipeline_demo_run.yaml
apiVersion: tekton.dev/v1beta1
kind: PipelineRun
metadata:
name: pipeline-demo-run
namespace: lizhe
spec:
serviceAccountName: build-bot-sa
pipelineRef:
name: pipeline-demo
resources:
- name: source-repo
resourceRef:
name: tektongolang-git
- name: tektongolang-image
resourceRef:
name: tektongolang-image
workspaces:
- name: build-workspace # this workspace name must be declared in the Pipeline
volumeClaimTemplate:
spec:
storageClassName: "local-path"
accessModes:
- ReadWriteOnce # access mode may affect how you can use this volume in parallel tasks
resources:
requests:
storage: 1Gi
