Kubernetes 1.23 Release


The Ephemeral containers feature moves from alpha to beta, which means it’s enabled by default in 1.23 clusters. Ephemeral containers are an excellent tool for troubleshooting, and we’ve written a hands-on guide to using them.


There are some deprecations and API changes in 1.23. You can view the complete list in the changelog. The Deprecated API Migration Guide is a great document for navigating these kinds of changes when upgrading. It’s worth bookmarking.

Thank you

Shout out to the SIG Release team once again for all of their hard work to ship 1.23. Release management is hard and often thankless work, and I appreciate their efforts so much. Also, I want to give a big thank you to everyone who contributed to 1.23. When I see such a long list of changes, it’s clear that many people worked hard to get them done.
