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 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.
