    Description

      I have a general conceptual question about microprofile-health api.

      In my application I implemented a detailed health status which results in a output with HTTP Code 200 as followed:
       

      {
      	"status": "UP",
      	"checks": [
      		{
      			"name": "imixs-workflow",
      			"status": "UP",
      			"data": {
      				"engine.version": "5.2.9-SNAPSHOT",
      				"model.groups": 1,
      				"model.versions": 1,
      				"index.status": "ok",
      				"database.status": "ok"
      			}
      		},
      		{
      			"name": "ready-deployment.imixs-office-workflow.war",
      			"status": "UP"
      		}
      	]
      }
      

      I am running this on Wildfly 20.0.1-Final
      My Kubernetes health check looks like this:

       

      spec:
        containers:
          ...
          livenessProbe:
            httpGet:
              path: /health
              port: 9990
            initialDelaySeconds: 120
            periodSeconds: 10
            failureThreshold: 3
         ...
      

      So I am using the default behaviour from Kubernetes here to validate the http response code 200=OK.

      But I run into situations where something bad happens and my application did not start correctly and is not deployed at all. This results on the server in a health status like this:

      { "status": "UP", }
      

       
      And so again we have http response code 200=OK and kubernetes thinks everything is fine, which is not the case.

      Is there any chance in eclipse microprofile-health or in WIlfly to force the Status=DOWN in case a specific deployment is missing?

      For example wildfly could return HTTP Status 204 or 206 if a deplyoment failed.

       

      I also asked the same question on microprofile-health on Github:

      https://github.com/eclipse/microprofile-health/issues/288

      And Martin Stefanko  suggested asking you at this place.
