Contour 1.8.0

on GitHub

We are delighted to present version 1.8.0 of Contour, our layer 7 HTTP reverse proxy for Kubernetes clusters.

There's been a bunch of great contributions from our community for this release, thanks to everyone!

We've also been busy with some big refactors to testing and other internals. The testing changes have come in, but the others should start being landed in the 1.9 timeframe. So this release is a stablisation release. Yay for paying down some tech debt!

Deprecations

Currently Contour supports annotating various objects with either projectcontour.io/<something> or contour.heptio.com/<something>. As of this release, contour.heptio.com annotations are deprecated, will have a warning log, and will be removed in a future release. Please move to using projectcontour.io annotations.

Inclusive Language changes

To ensure our community is as welcoming as possible, we've migrated our main development branch from its old name of master to main. As part of this effort, the auto-built Docker Hub image tag has also been moved from master to main.

Moving forward, we'll be using the guidelines of the Kubernetes Naming working group as a base for our own efforts to stay as inclusive as we can manage.

As part of this work, we've also run some automated checks against our code base using the vale tool, with minimal changes.

New and Improved

• Contour's fix for 421 redirects and SNI now handles misdirected requests case insensitively (#2764)
• There have a been a few improvements to Contour's shutdown behavior: @laurovenancio has fixed some bugs with the contour shutdown command for managing Envoy's shutdown process (#2817 and #2820), and there was a fix to ensure that Ctrl-C will actually shut down Contour when running locally (#2797).
• @ffahri added some helpers for retrieving the version of Kubernetes objects, and fixed an erroneous log (#2808).
• @tsaarni added upstream certificate validation for HTTP/2 (#2832).
• Contour now parses its YAML configuration strictly. Thanks @tthebst for PR #2765.
• Some great docs fixes from @derkoe (#2790), @rajat404 (#2804), and @tong101 (#2839).
• @aberasarte had a design proposal for CORS accepted (#1012), after a long and detailed discussion. We're all looking forward to seeing this design implemented.

Thanks to all of our external contributors, this is the most ever in one release! 🥇 🎉
