Argo Workflows build demo
本例将演示如何使用 Argo workflows 来进行一次完整的 CI/CD
- 创建demo用的 react 项目，为了更贴近实际项目，这里使用的是一个私有库
在这个仓库中我们准备了一个简单的 react helloworld 项目
2. 创建 docker 权限用的 secrets
kubectl create secret docker-registry regcred --docker-server=https://index.docker.io/v1/ --docker-username=YOURNAME --docker-password=YOURPASSWORD --docker-email=YOUREMAIL@ADDRESS -n argo3. 准备dockerhub仓库
libaibai/argobuilddemo4. 创建 build.yaml 文件
参考 https://github.com/argoproj/argo-workflows/blob/master/examples/buildkit-template.yaml
为了方便测试，这里加入了 ttl 并且把官方文档上的 WorkflowTemplate 替换成了 Workflow
官方文档上使用的是 buildkit ，下面的例子中我使用的是 kaniko
apiVersion: argoproj.io/v1alpha1
kind: Workflow
metadata:
generateName: buildkit-
namespace: argo
spec:
ttlStrategy:
secondsAfterCompletion: 1800 # Time to live after workflow is completed, replaces ttlSecondsAfterFinished
secondsAfterSuccess: 1800 # Time to live after workflow is successful
secondsAfterFailure: 1800 # Time to live after workflow fails

此例子中使用的
storageClassName: local-path
是通过以下脚本创建的，但是只能使用在 测试环境中 参考 使用hostpath作为VolumeClaimsTemplate
当然如果真的没有办法使用NFS卷或者其他可共享的pv卷，可以考虑使用 nodeselector 将build pod固定在某个特殊的节点上
kubectl apply -f https://raw.githubusercontent.com/rancher/local-path-provisioner/master/deploy/local-path-storage.yaml
kubectl create -f https://raw.githubusercontent.com/rancher/local-path-provisioner/master/examples/pvc/pvc.yaml使用的Dockerfile
FROM nginx:1.19
COPY build /usr/share/nginx/html
