Connectivity

  • Connectivity ingress-nginx-app v1.6.8

    Changed

    • Default max-worker-connections to 0, making it same as max-worker-open-files i.e. max open files (system's limit) / worker-processes - 1024. This optimizes for high load conditions where it improves performance at the cost of increasing RAM utilization (even on idle).
    • HorizontalPodAutoscaler was tuned to use targetMemoryUtilizationPercentage of 80 due to increased RAM utilization with new default for max-worker-connections of 0.
    • Removed use of enable-dynamic-certificates CLI flag, it has been deprecated since ingress-nginx 0.26.0 via ingress-nginx PR #4356
    • Changed default error-log-level from error to notice.
    • Added a link to the README in the sources of Chart.yaml
  • Connectivity ingress-nginx-app v1.6.7

    Changed

    • Align graceful termination configuration with changes made in upstream ingress-nginx 0.26.0 (see related PR #4487 and important section in 0.26.0 release notes).
      • Make NGINX IC Deployment’s terminationGracePeriodSeconds configurable and align its default with configmap.worker-shutdown-timeout
      • Make NGINX IC controller container lifecycle hooks configurable, and change from sleep 60 to using /wait-shutdown as preStop hook.
    • Make controller.minReadySeconds configurable.
  • Connectivity ingress-nginx-app v1.6.6

    Changed

    • Change deployment to use release revision not time for Helm 3 support.
  • Connectivity kong-app v0.7.2

    Updated

    • Enable Giant Swarm monitoring
    • Set default ingressClass to kong-app. See #48
  • Connectivity ingress-nginx-app v1.6.5

    Changed

    • Fix small cluster profile resource requests. (#42)
  • Connectivity coredns-app v1.1.8

    Changed

    • Use cluster.kubernetes.clusterDomain instead of cluster.kubernetes.domain for custom DNS suffix.
  • Connectivity coredns-app v1.1.7

    Changed

    • Set autopath variable to disabled by default in values file.
  • Connectivity ingress-nginx-app v1.6.4

    Changed

    • Disable HPA and PDB for xs clusters since NGINX Deployment resource requests are not set there. (#40)
  • Connectivity ingress-nginx-app v1.6.3

    Changed

    • Adjust resource requests, HPA and PDB depending on determined cluster profile; supported cluster profiles include xxs, xs, small, and larger than small or unknown. (#38) By default, for nginx on:
      • xxs clusters - clear resource requests, HPA and PDB are disabled
      • xs clusters - clear resource requests, enabled HPA and PDB
      • small clusters - have some resource requests, HPA and PDB are enabled
      • clusters larger than small or unknown - have decent resource requests i.e. capacity out-of-the-box, and HPA and PDB are enabled.
  • Connectivity ingress-nginx-app v1.6.2

    Changed

    • Reintroduced config properties which should have been just deprecated but got dropped prematurely in v1.4.0 (#36)
      • configmap.annotations-prefix
      • configmap.default-ssl-certificate
      • configmap.hpa-enabled
      • configmap.hpa-max-replicas
      • configmap.hpa-min-replicas
      • configmap.hpa-target-cpu-utilization-percentage
      • configmap.hpa-target-memory-utilization-percentage
      • configmap.ingress-class
