In this week’s newsletter we feature an episode of Containers from the Couch on API Priority and Fairness (APF) . APF is a way to give priority to certain API calls over other, lower priority, calls. The idea is to prevent the Kubernetes API server from becoming overwhelmed and unresponsive. If you have an application that calls the Kubernetes API and it receive a 429 (too many requests) error, it could be an indication that your application has been “throttled”. The remedy might involve updating your application to re-try the request, reducing the number of calls your application makes to the API by implementing a watch, or creating a new “flow” that gives the calls from your application a higher priority.

The other big announcements this week include the launch of security groups for Network Load Balancers and a deploy-to-Kubernetes action for CodeCatalyst!
