Description Denis Ollier 2021-08-02 15:34:58 UTC

Description of problem
----------------------

Deployment of CNV is failing due to kube-cni-linux-bridge-plugin getting in CrashLoopBackOff state because files are missing from the container image:

> kubectl -n openshift-cnv logs kube-cni-linux-bridge-plugin-7rnh5
> 
> Installing bridge and tuning CNIs
> cp: cannot stat '/usr/src/github.com/containernetworking/plugins/bin/bridge': No such file or directory

Version
-------

OCP: v4.9.0-0.nightly-2021-07-24-064622
RHCOS: v49.84.202107220219-0
CNV: http://cnv-version-explorer.apps.cnv.engineering.redhat.com/BundleDetails?ver=v4.9.0-66
cnv-containernetworking-plugins: v4.9.0-7

How reproducible
----------------

100%

Steps to Reproduce
------------------

Install CNV-v4.9 from the following IIB image: registry-proxy.engineering.redhat.com/rh-osbs/iib:95527.

Actual results
--------------

kube-cni-linux-bridge-plugin Pods fail to start:

> kubectl get pods -n openshift-cnv -l app=cni-plugins
> 
> NAME                                 READY   STATUS             RESTARTS   AGE
> kube-cni-linux-bridge-plugin-7rnh5   0/1     CrashLoopBackOff   6          10m
> kube-cni-linux-bridge-plugin-c2lwd   0/1     CrashLoopBackOff   6          10m
> kube-cni-linux-bridge-plugin-mb4j6   0/1     CrashLoopBackOff   6          10m
> kube-cni-linux-bridge-plugin-mbxk9   0/1     CrashLoopBackOff   6          10m
> kube-cni-linux-bridge-plugin-xbp7j   0/1     CrashLoopBackOff   6          11m
> kube-cni-linux-bridge-plugin-xhh7x   0/1     CrashLoopBackOff   6          10m

The cause seems to be missing files from the cnv-containernetworking-plugins container image:

> kubectl -n openshift-cnv logs kube-cni-linux-bridge-plugin-7rnh5
> 
> Installing bridge and tuning CNIs
> cp: cannot stat '/usr/src/github.com/containernetworking/plugins/bin/bridge': No such file or directory

Expected results
----------------

kube-cni-linux-bridge-plugin Pods should start properly.
