Overview of the Issue

• Deregister services after unhealthy We scale down the microservices massively (ej: 10 to 1 pod ), and some instance services don't deregister. All the microservices use a deregister process when they are dying, so we used DeregisterCriticalServiceAfter property to ensure deregistering on consul but the minimal delay is one minute and I want to deregister immediately or auto deregister after fail health check configurable through some property.

Somebody had the same situation?

Reproduction Steps

Scenario: consul image: 1.14.2, using 3 server We have terragrunt and terraform, using the default value.yaml, and replace those properties👇:

{
"server.replicas" = 3
"client.enabled" = false
"connectInject.enabled" = false
"syncCatalog.enabled" = false
"global.acls.manageSystemACLs" = false
"global.acls.nodeSelecor" = "group:kafka"
}

When: we scale down the microservices massively (ej: 10 to 1 pod ), some instance services don't deregister
