Hi I am trying to install Kubernetes from a private repo of pre scanned images. The problem is Kubeadm is looking for specifically named containers. For example "kube-apiserver". The problem is the image name is "kube-apiserver-1-20". I dont have access to this private repo to change the name of the image. I am using a Kubeadm config file with the properties listed inside. Is there any way to modify this Kubeadm config file to look for the container I need? Thanks.
kubeadmConfig.yaml:
apiVersion: kubeadm.k8s.io/v1beta1
kind: ClusterConfiguration
apiServer:
image: kube-apiserver-1.20 #wasnt sure "image" could be used to change name
imageTag: "latest" #I have tried changing this around too.
imageRepository: ironbankkubernetes-1.20
Error: image ironbank/opensource/kubernetes-1.20/kube-apiserver:v1.20.6 not found
, error: exit status 1
The image name is ironbank/opensource/kubernetes-1.20/kube-apiserver-1-20:v1.20.6
Did you properly indent with yaml format?
Otherwsie, it will ignore and go for default.
And read the document, seems you missed another layer with extraArgs
apiVersion: kubeadm.k8s.io/v1beta1
kind: ClusterConfiguration
apiServer:
extraArgs:
image: kube-apiserver-1.20
imageTag: "latest"
imageRepository: ironbankkubernetes-1.20
