        type: depends-on-app
        properties:
          name: another-app
          namespace: default

depends-on-app will check if the cluster has the application with name and namespace given in properties. If the application exists, it will hang the next step until the application is running. If the application does not exist, KubeVela will check the ConfigMap with the same name, and read the config of the Application and apply to cluster. The ConfigMap is like below: the name and namespace of the ConfigMap is the same in properties. In data, the key must be specified by application, and the value is the yaml of the deployed application yaml.

apiVersion: v1
kind: ConfigMap
metadata:
  name: myapp
  namespace: vela-system
data:
  application: 
    <app yaml file>

名称	描述	类型	是否必须	默认值
name	需要等待的 Application 名称。	string	true
namespace	需要等待的 Application 所在的命名空间。	string	true
