Description nijin ashok 2021-05-13 04:54:32 UTC

Description of problem:

The request is mainly to backport the upstream fix https://github.com/openshift/ovirt-csi-driver/pull/53. In one of the customer environment, the ovirt-csi-driver-node was in "CrashLoopBackOff" status since port 8080 was used by another service. The user had to delete the conflicting service to make the pod up.


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


How reproducible:
100%

Steps to Reproduce:

1. Create another service to listen on port 8080.


Actual results:

Port 8080 of oVirt CSI driver is causing collisions with other services

Expected results:

Backport https://github.com/openshift/ovirt-csi-driver/pull/53

Comment 3 Thomas Mueller 2021-05-19 05:50:19 UTC

IMHO the issue depends on the external ip. The ovirt container fails to bind to 8080 only on the node which has added the additional IP to the interface.

My take on formulating "Steps to Reproduce":

1. Create a service with external IP to listen on port 8080.
2. ensure the services external ip is added to some nodes primary network interface

Comment 9 Guilherme Santos 2021-05-31 18:36:07 UTC

Verified on:
4.7.0-0.nightly-2021-05-28-053625

Steps:
1. created nginx service on port 8080
# oc new-app nginx:1.16~https://github.com/sclorg/nginx-container.git --context-dir=1.16/test/test-app/
2. checked ovirt-csi-driver-node pods 
# oc get pods -n openshift-cluster-csi-drivers

Results:
pods running as expected and no "CrashLoopBackOff"
