在Step中运行脚本  需要在Step中执行复杂操作时，可以使用“script”直接指定要运行的脚本 　　◼ 多行脚本，可以使用“|”启用 　　◼ script同command互斥 
root@master01:~/tekton-and-argocd-in-practise/02-tekton-basics# cat 04-task-step-with-script.yaml 
apiVersion: tekton.dev/v1beta1

        echo "Step with Script..."
        echo "Installing necessary tooling"
        apk add curl
        curl -s www.magedu.com && echo "Success" || echo "Fail"
