Tracking issue for CNI 1.4

Created a 1.4 Milestone

[StevenACoffman]

ref eksctl-io/eksctl#736

[mogren]

Released on GitHub, but still not used in the default EKS AMI.

[StevenACoffman]

@tabern is this the AMI default now?

[mogren]

@StevenACoffman It's not yet the default.

We are working on a few minor tweaks, like updating metrics to work with the new prometheus endpoints (aws/amazon-vpc-cni-k8s#413) and some Calico cleanups (aws/amazon-vpc-cni-k8s#410, aws/amazon-vpc-cni-k8s#421) before making it the default.

[StevenACoffman]

Where can we track the change to AMI default, if not this issue?

[StevenACoffman]

@mogren I see 1.4.1 just released with all the issues you mention merged. Is there a tracking issue for when 1.4.x will be the AMI default?

[tabern]

Hey @StevenACoffman this is actually the issue for tracking 1.4.2 as the AMI default. We closed it in error last week.

[mogren]

Still not the default, but we will roll it out soon.

[mogren]

Starting today, CNI v1.4.1 is the default for new EKS clusters. If you were using the old cni-metrics-helper, please update to the newer build.
