Next Deadline: Enhancements Freeze, Sept. 9
The 1.23 release cycle began today. As always, the call for Enhancements is the first activity we’ll see, and notably the PRR Committee would like to see the PRR part of your KEP a week before, on Sept. 2nd, if at all possible.
1.22.1, with the first batch of post-release fixes, is now available.
One of the backwards-incompatible changes in Go 1.17 is that
net.ParseCIDR now reject IPs with leading zeroes, such as
1.2.3.004. In Go 1.16 these would parse but octets with a leading zero would be interpreted as octal, leading to both user confusion and potential security issues in edge cases. This unfortunately puts us in a difficult place as we can’t (or at least really prefer not to) change the validation behavior in ways that affect existing stored data. As a temporary “no worse than it was before” solution we have added two functions to
ParseCIDRSloppy. If you are interacting with stored IPs or CIDR masks in Kubernetes types, please make sure you use these going forward rather than the
net versions. And stay tuned for future updates as this is hopefully only a stopgap answer.
The graceful node shutdown allows giving pods time to be evicted before a node terminates or reboots. As a new addition, this will also yield a
Shutdown type event into the Node object’s event stream. This can be used for fleet analysis, scripting waits, or alerting.
And finally a short but useful feature, a
--startup-send-retry-after-until-ready=true command line option for kube-apiserver to set it to return an HTTP 429 Too Many Requests and a
Retry-After header in the (short) time between the listening socket being opened and the API server being ready for requests. If you work on a Kubernetes client that doesn’t already support 429/Retry-After, now would be a great time to add it!
