Release Notes / Changelog

Summary

The following update mitigates emergent resilience issues in DSS that have presented during Onboard testing. Additionally, health checks are added for the DSS service to facilitate further observability and automated container restarts when necessary.

DSS

• JAXBContext is now cached within JAXBContextServiceImpl.

• Removed use of UnmarshallerPool and MarshallerPool

Health Checks

The following Terraform spec should be leveraged as reference for configuration of DSS liveness and readiness probes.

liveness_probe {
  http_get {
      path = "/opencds-decision-support-service/_k8s-health-check"
      port = 8080
  }
  initial_delay_seconds = 90
  period_seconds        = 30
  timeout_seconds       = 5
  failure_threshold     = 3
  success_threshold     = 1
}

readiness_probe {
  http_get {
      path = "/opencds-decision-support-service/_k8s-health-check"
      port = 8080
  }
  initial_delay_seconds = 90
  period_seconds        = 30
  timeout_seconds       = 5
  failure_threshold     = 3
  success_threshold     = 1
}
