Can we stop kubernetes containers running with default UCP installation

ucp

(Dipanjan) #1

Hi All,
We are using Docker Engine : 17.06.2-ee-16 and UCP version is 3.0.5. I know Kubernetes is now merged with default UCP installation and couple of kubernetes related containers (listed below) are running with default UCP installation which is also part of UCP architecture as per Docker doc.


My question is, in our environment we are not initialized kubernetes cluster yet and we don’t have any binaries and config files related to kubernetes yet so can we permanently stop the below listed containers or if we do it will effect on UCP. As we don’t have any intention to enable Kubernetes now and recently kubernetes related vulnerability is opened and our security team found traffic on kube-apiserver container. Are we safe to run those containers or can we stop them permanently.
kubernetes related containers list :
ucp-kube-apiserver
ucp-kube-controller-manager
ucp-kube-scheduler
k8s_install-cni_calico-node
k8s_calico-node_calico-node
k8s_POD_calico-node_kube-system
ucp-kube-proxy
ucp-kubelet
ucp-kv
