The problem is that I'm not a kubernetes expert, just trying to get something up to understand how it work. My registry have the correct CA configured, I already use it from other docker machines.

From the VIO Kubernetes virtual appliance (the one used to deploy kubernetes cluster) I've configured my corporate ca correctly and I can login with docker on my registry  without any problem.

The problem is when i try to deploy a pod with images on this registry.

I think that in this case the machine trying to get the image are the "kubernetes nodes" that don't have my corporate ca in the trusted ca or in the /etc/docker/certs.d/registryserver/ directory.

I'm trying to understand how to push a certificate on the kubernetes nodes/master virtual machine but I don't know how to login on those or if there's any command to do it on the management.

I've found a site with some instruction on how to connect to the various nodes.

From the vio for kubernetes management machine:

vkube  login --insecure

vkube cluster list --insecure

Make a note of the Cluster ID of the cluster you want to access

vkube cluster show <Cluster ID> --insecure

Make a note of the IP of the Master and Worker Nodes.

docker exec -it app-api /bin/bash

cd /var/lib/vrc/terraform/<ClusterID>

ssh -i private.key -F ssh-bastion.conf ubuntu@Kubernetes_Host_IP_Address
