How to uninstall Genie plugin

[icy]

I'd need to uninstall the plugin on some cluster. However it looked like the system still recognizes the one when I try to delete the pugin (kubectl delete -f- manifest.yaml)

NetworkPlugin cni failed to set up pod "foo-bar" network: CNI Genie Add IP internal error: 
Error getting annotations for pod (foo-bar): No pod or env var found, result: %!!(MISSING)s(<nil>)

Am I missing something?

Thanks

We actually installed the plugin via https://quay.io/repository/huawei-cni-genie/genie-plugin?tab=history

https://raw.githubusercontent.com/Huawei-PaaS/CNI-Genie/master/conf/1.8/genie-plugin.yaml

Delete the installation (kubectl delete -f- < genie-plugin) doesn't help much

Does anyone have answer for this in 2021? For me when I recreate the node, I didn't get this error. But getting this error in existing node. I believe some cleanup is needed in the host filesystem.

Did you figure out a solution?

This is annoying, I tried to install it, it could not be installed. Now I want to continue working without it, now my pods cannot be created because the CNI Genie is stuck and cannot be removed.

@MohammedNoureldin Could you please share with me additional information to help me repro the issue?

1. K8s version on which CNI-Genie is being deployed.
2. Yaml used to deploy CNI-Genie

I think what I did in the past (work) to uninstall the plugin was as below

• Modify the script: launch.sh (https://github.com/cni-genie/CNI-Genie/blob/master/conf/1.8/launch.sh) so that when the script starts, it would remove all genie's files under /host/etc/cni/net.d/, and then the script sleeps let's say 10000s (aka almost forever)
• Generate new docker image with new script (see Dockerfile under https://github.com/cni-genie/CNI-Genie/tree/master/conf/1.8)
• You apply the same manifest with newly built docker image, the script will be launched and remove the files for you
• Then you delete the whole installation by using kubectl delete -f the_modified_manifest.yaml

Of course please make sure you have some alternative CNI on your system otherwise everything would get stuck after you uninstall cni-genie plugin.

Hope this helps. Though I think there would be some better way.

Edit: type fix. docker-build note.
