This update modifies the Kubernetes patch kubeadm-create-platform-pods-with-zero-CPU-resources.patch to set the CoreDNS memory request to zero. Test Plan: PASS: Run all Kubelet, kubeadm, kubectl make tests for affected code. PASS: All affected versions of kubernetes package build successfully. PASS: Verify the CoreDNS pod by describing it and ensure that the memory request is set to zero.

Subject: [PATCH] kubeadm: create platform pods with zero CPU resources
|
|
|
|
We want to specify zero CPU resources when creating the manifests
|
|
for the static platform pods, as a workaround for the lack of
|
|
separate resource tracking for platform resources.
|
|
|
|
We also specify zero CPU and Memory resources for the
|
|
coredns deployment.
|
|
manifests.go appears to be the main file for this, not
|
|
sure if the others are used but I changed them just in case.
