Hey @nibalizer

it seems that some integration tests are not passing, also this PR needs to be rebased on top of the current master branch.
Could you take a look pls?

Thanks in advance

Just add my observation here, in PR 1337 we have the list

# Containers from IBM Cloud
- list: ibm_cloud_containers
  items:
    - icr.io/ext/sysdig/agent
    - registry.ng.bluemix.net/armada-master/metrics-server-amd64
    - registry.ng.bluemix.net/armada-master/olm

a commercial image(sysdig/agent) from cloud vendor. We haven't decided whether we should allow commercial images in the exception. Just approve for now, probably will change the list when a decision is made.

Whitelist ibm images for connecting to k8s api server

IBM Observability by Sysdig has a vendored sysdig/agent image.

IBM's Kubernetes Service ships with an operator manager. Example:

19:12:45.090908160: Notice Unexpected connection to K8s API Server from
container (command=catalog -namespace ibm-system
-configmapServerImage=registry.ng.bluemix.net/armada-master/configmap-operator-registry:v1.6.1
k8s.ns=ibm-system k8s.pod=catalog-operator-6495d76869-ncl2z
container=4ad7a04fa1e0
image=registry.ng.bluemix.net/armada-master/olm:0.14.1-IKS-1
connection=172.30.108.219:48200->172.21.0.1:443) k8s.ns=ibm-system
k8s.pod=catalog-operator-6495d76869-ncl2z container=4ad7a04fa1e0

IBM's Kubernetes service also ships with a metrics collecting agent
