Descrizione

Use Case

Use the scretstore http plugin to retrieve connection information from postgresql output. However, in the current situation, if the secretstore http plugin fails to retrieve the API value, the service does not start because @ variable substitution is not performed.

Expected behavior

  • API call setup : Use @ variable
  • API connection failure : Retry

Actual behavior

  • API call setup : Use @ variable
  • API connection failure : service down ( The reason is that the @ variable does not have a value and attempts to connect in an unsubstituted state.)

Additional info

  timeout = "5s"
