Extensions field to Helm in Terminus

During installation, Terminus injects extended field into the APP, using the configuration from TerminusManifest.yaml.

The information from these extended fields can be directly referenced in the template without being defined in values.yaml. If there are definitions in values.yaml with the same name, the system value will overwrite them.

• User Infomation

  Value	Type	Description
  .Values.bfl.username	String	Username of the currently installing APP
  .Values.user.zone	String	Domain of the current user

• Domain Information

  Value	Type	Description
  .Values.domain	Map<String,String>	Define the Entry for the App, using the entrance name as the key and the URL as the value.

• Storage Information

  Value	Type	Description
  .Values.userspace.appData	String	Cluster storage address available to the APP
  .Values.userspace.appCache	String	Local node cache address available to the APP
  .Values.userspace.userData	String	storage directory of User's data

• Cluster Information

  Value	Type	Description
  .Values.cluster.arch	String	Cluster CPU archtecture

  Multi-platform (AMD64 and ARM) cluster is not supported for now.

• Application Dependencies

  Value	Type	Description
  .Values.deps	Map<String, Value>	Current address and port of the applications the APP depends on
  .Values.svcs	Map<String, Value>	Other services and ports of the applications the APP depends on

  When an application sets dependencies on another application, this will be passed through the deps parameter. For instance, if an application, sets a dependency on another application called 'A-Server', and 'A-Server' sets the entry name as 'aserver' with the entry host configured as 'aserver-svc', the value will be like:

  {
    "aserver_host": "aserver-svc.<A-Server namespce>",
    "aserver_port": 80
  }

  At the same time, svcs will pass in all services of A-Server.

  {
    "aserver-svc_host": "aserver-svc.<A-Server namespce>",
    "aserver-svc_port": [80]    # If there are multiple ports in the service, they will be passed in together.
  }

  .Values.postgres.username	String	PostgreSQL database username
  .Values.postgres.password	String	PostgreSQL database password
