CHANGELOG

v0.11

Highlights of this version

  • HAProxy upgrade from 2.0 to 2.1.
  • Negligible IO, CPU usage and reconciliation time, regardless the number of tracked ingress and service objects.
    • HAProxy Ingress deployed on noisy (about 10 reconciliations per minute) and big (about 4000 ingress and services) clusters used to use about 90% CPU. HAProxy Ingress v0.11 uses about 2% CPU on such clusters when using backend shards.
  • Ingress API upgrade from extensions/v1beta1 to networking.k8s.io/v1beta1.

Breaking backward compatibility from v0.10

  • Kubernetes version 1.14 or newer
  • HAProxy Ingress service account need get, list, watch and update access to networking.k8s.io api group - which was the same permitions granted to extensions/v1beta1 api group. Update your k8s role configuration before deploy v0.11. See an updated version of the deployment manifest.
  • timeout-client and timeout-client-fin are global scoped only - cannot use as an ingress annotation.

v0.9

v0.9-beta.1

v0.8

v0.8-beta.1

Breaking backward compatibility from v0.7:

Note: A new configuration parser and HAProxy config builder is in place. Despite declared incompatibility changes listed below, all configuration options and behavior should be preserved. Please file an issue if something changed in the v0.8 controller which is not listed here.

  • HAProxy's backend naming convention used for services changed from <namespace>-<svcname>-<port> to <namespace>_<svcname>_<port> in order to avoid ambiguity. This should impact as least logging filters and metrics dashboards.
  • All the other HAProxy's proxy names changed as well - check your logging filters and metrics dashboards.
  • nbproc-ssl global configmap option wasn't reimplemented in v0.8, consider use nbthread instead.
  • strict-host global configmap option changed the default value from true to false. See strict-host doc.
  • dynamic-scaling configuration key changed the default value from false to true
  • nbthread configuration key changed the default value from 1 to 2
  • reload-strategy command-line option changed the default value from native to reusesocket

The --v07-controller=true command-line option can be used to revert to the old controller and behavior. Note that in this case the *-v07.tmpl templates will be used instead. This option will be removed on v0.10.

Improvements on the new internal representation and converters:

  • Main issue #274
  • Pull requests part1, part2, part3, part4, part5, part6
  • About 80% of the controller was rewritten from scratch. The new code base has more consistent behavior, it's more decoupled, easier to understand, test and evolve, and ready to ingress v2 without breaking compatibility with ingress v1. The new configuration is also a lot faster - the bigger the cluster, the faster the config generated by the v0.8 controller.
  • Configmap and annotations: declare annotations with prefix (defaults to ingress.kubernetes.io) on services or ingress objects, declare without prefix as a global configmap option. The configmap declaration act as a default value, and service takes precedence in the case of conflict with ingress.
  • The mode tcp frontend will be used only if needed:
    • Authentication with client certificate is used - this will not be a limitation on v0.9 controller and HAProxy 1.9.x
    • ssl-passthrough is used
    • Conflicting timeout client declared as annotations
  • Fix HAProxy config parsing of a very long list of whitelist CIDRs or a very long list of overlaping /paths in the same domain

Fixes and improvements since v0.7:

  • Fix duplication of ConfigFrontend snippets for DefaultBackend #352

v0.6-beta.1

Breaking backward compatibility from v0.5:

  • Multibinder is deprecated, use reusesocket reload strategy instead - #139
  • Dynamic scaling do not reload HAProxy if the number of servers of a backend could be reduced
  • Broken CIDR lists - whitelist-source-range and limit-whitelist annotations - will add at least the valid CIDRs found in the list - #163
