Changelog

All notable changes to this project are documented in this file.

0.14.0

Release date: 2021-05-11

This prerelease comes with support for sending events to Azure Event Hub.

Features:

  • Add support for Azure EventHub provider #191

Improvements:

  • Redact token from error log #196
  • Add note about exposing receiver to the internet #193

0.13.0

Release date: 2021-04-21

This prerelease comes with support for sending alerts to HTTPS servers with self-signed TLS certs.

Features:

0.12.0

Release date: 2021-03-26

This prerelease comes with support for sending alerts to Sentry.

Starting with this version, events are subject to rate limiting to reduce the amount of duplicate alerts sent by notification-controller. The interval of the rate limit is set by default to 5m but can be configured with the --rate-limit-interval command arg.

The event server exposes HTTP request metrics to track the amount of rate limited events. The following promql will get the rate at which requests are rate limited:

rate(gotk_event_http_request_duration_seconds_count{code="429"}[30s])

Features:

  • Add support for Sentry provider #176

Improvements:

  • Add rate limiter to event http servers #167

0.11.0

Release date: 2021-03-26

This is the eleventh MINOR prerelease.

This prerelease comes with support for sending alerts to Webex and for posting commit status updates to GitHub enterprise.

This prerelease comes with a breaking change: the leader election ID was renamed from 4ae6d3b3.fluxcd.io to notification-controller-leader-election. This change should however not have a direct impact.

The suspended status of resources is now recorded to a gotk_suspend_status Prometheus gauge metric.

Features:

  • Add support for Webex as an alert provider #168
  • Add support for GitHub enterprise commit status #162

Improvements:

  • Set leader election deadline to 30s #170

0.7.1

Release date: 2021-01-26

This prerelease adds *Kind string constants for the kind objects exposed by the API to further normalise it to GitOps Toolkit standards.

Improvements

  • Add kinds to API types #131

0.7.0

Release date: 2021-01-22

This is the seventh MINOR prerelease.

The Receiver API gains a new webhook type called generic-hmac, that validates the caller legitimacy using HMAC signatures.

The Alert API comes with support for image update notifications and is now possible to trigger container image updates to Git using Sonatype Nexus webhooks.

Two new argument flags are introduced to support configuring the QPS (--kube-api-qps) and burst (--kube-api-burst) while communicating with the Kubernetes API server.

The LocalObjectReference from the Kubernetes core has been replaced with our own, making Name a required field. The impact of this should be limited to direct API consumers only, as the field was already required by controller logic.

Features:

  • Add generic webhook receiver for HMAC signing #127
  • Add Nexus webhook receiver #126

Improvements:

  • Add the object kind to notification messages #124
  • Allow ImageUpdateAutomations in object refs #128

Features:

  • Add GCR webhook receiver #121
  • Add Quay webhook receiver #118

Improvements:

  • Update Kubernetes packages to v1.20.2 #119

0.6.1

Release date: 2021-01-14

This prerelease comes with support for triggering container image updates to Git using webhook receiver and fixes a regression bug introduced in v0.6.0 that caused reconciliation request annotations to be ignored in certain scenarios.

Features:

  • Trigger ImageRepository reconciliation with webhook receivers #110
  • Implement DockerHub webhook receiver #112

Improvements:

  • Upgrade runtime package to v0.6.2 #111

0.6.0

Release date: 2021-01-12

This is the sixth MINOR prerelease, upgrading the controller-runtime dependencies to v0.7.0.

The container image for ARMv7 and ARM64 that used to be published separately as notification-controller:*-arm64 has been merged with the AMD64 image.

0.5.0
