Week Ending April 21, 2019

Developer News

The Kubernetes project operates by GitOps as much as possible, so our Slack configuration and channel management happens in GitHub, too. Need a new channel, or to change owners or topics for an existing channel? Submit a PR to kubernetes/community. The tools that automate this are in slack-infra, so if you like Slackops and Gitops: contributors wanted.

Release Schedule

Next Deadline: Enhancements Freeze, April 30th

The Release Team is fully staffed and Claire posted the schedule, so 1.15 is now fully underway. This means that the Enhancements team have been collecting features and KEPs. By April 30th, your feature or modification needs to be in the enhancements repo, likely with an attached KEP.

1.15.alpha1 came out last week, and release notes collection starts this week.

1.12.8 is expected out this week.

Featured PRs

test-infra#9387: Disallow at mentions and keywords which close issues in commit messages

Due to issues with cross-talk between personal forks of k/k and GitHub’s “helpful” close-issue-via-commit-message integration, we’ve now set up a Prow plugin to block at-mentions and those GitHub keywords from commit log messages. They are still allowed and encouraged in Issues/PRs, just not the commit messages themselves. The Prow plugin will explain all this again if you run afoul of its watchful gaze, but something to keep in mind.

#75474: add heartbeat inside watch

An implementation of the Watch Bookmark KEP, this PR sets up a heartbeat system inside API watches which should allow for both faster resumption on reconnects as well as lower server load. As anyone with a large fleet of custom controllers reconnecting at once knows, this is going to help a lot.

test-infra#12308: Added Mermaid and SVG for Common Interactions Sequence Diagram

While the PR is relatively small, it gives us this lovely image to show the PR process in a nutshell:
