Description Meng Bo 2019-01-25 11:14:37 UTC

Description of problem:
We are using a hardcoded namespace `kube-system` which will ignore the setting in defaultNetworks for multus.

This is not a problem in kubernetes cluster or OCP 3.x cluster, since all the critical service are deployed under kube-system. 

But for OCP 4.0, there is a lot of system services which are running in different namespaces.
Eg, 
the coredns in running in openshift-dns namespace

We should change the hardcoded kube-system to a configurable list.


Version-Release number of selected component (if applicable):
4.0

How reproducible:
always

Steps to Reproduce:
1.
2.
3.

Actual results:
The pod will ignore the defaultNetworks crd in kube-system only.

Expected results:
As we discussed in PR https://github.com/intel/multus-cni/pull/203
The coredns service is not running in kube-system now.

We should update the kube-system namespace or even better have a configurable list.

Is this downstreamed? can this be marked as MODIFIED?

Comment 3 Tomofumi Hayashi 2019-03-06 14:57:21 UTC

Casay,

Thank you for your reminder!
Verified that the fix is in downstream, https://github.com/openshift/multus-cni/commit/73e10fb99993963aa73125aeffffa685776e3090 so changed to MODIFIED.

Comment 6 Meng Bo 2019-03-18 10:13:39 UTC

Tested on 4.0.0-0.nightly-2019-03-15-063749

The new added parameters systemNamespaces and multusNamespace are both working fine.

Move the bug to verified.
