feat: Store kubearmor policies in OCI registeries and Leverage OCI Hooks for Container Events

[kranurag7]

Store KubeArmor policies in OCI registeries and use OCI hooks to get container events

• [ ] kubearmor-client should be able to interact with OCI registeries for listing, pushing, pulling and verifying policies.
• [ ] Use OCI hooks and get events in context to container start/stop: Currently KubeArmor mounts docker/containerd/crio UNIX domain socket file in KubeArmor to watch for container events. The aim is to use OCI hooks for getting such container events.

Hello, I'm interested in working and learning more about this under GSOC. I'm finished with the KubeArmor development setup. Next step is to get familiar with the references provide above right?

@kranurag7 I'm pretty intrigued with this project, so are the references provided in the issue description enough to get started??

[ShivangShandilya]

@kranurag7 so I have been studying this issue for a while now, correct me if I misunderstood anything. So, basically what we have to do is store the kubearmor policies in an OCI artifact so that kuberarmor-client can perform functions like push and pull of various policies. Upon further reading I found that DockerHub is currently not supporting OCI artifacts, so we might have to use an alternative such Amazon ECR or Github Container Registry. After doing this task all we have to do is list all those policies on artifacthub. Am I correct?? If I understood this correctly I would definitely like to work on this.

Is KubeArmor planning to participate with this issue in LFX June term? I am really looking forward to work on it under a mentor.

Yep, KubeArmor maintainers will submit the proposals for LFX June term.

I know Goland and have meduim-level understanding of containers. I would be happy to work on this issue. Firstly, I will go through the documentation and try to set up the project locally. I am eager to participate and will submit my application as soon as the mentee applications open.

Hey, I have understanding of Go(basic) and K8s, and I also have some familiarity with Open container Initiative(OCI). I'm interested in participating in the LFX mentorship program. To begin, I plan to explore and set up Kubearmor locally. I will go through the issue and will try to understand. Could you please recommend some resources that can help me understand the topic better?

So,Our goal is to save the KubeArmor policy in an OCI (Open Container Initiative) registry, which will enable the Kubearmor client to communicate with the OCI registry. That includes pushing, pulling, and verifying the policies, like container images. Additionally, by implementing OCI hooks, we can capture container start and stop events. I would like to work on this issue.

Hey @kranurag7, I have an understanding of OCI's , kuberenetes, golang and docker. I am interested in applying for this project, and will apply soon : )

Progress of OCI registry feature can be tracked here: https://github.com/akshay196/kubearmor-client/tree/oci-registry-pull-push (I will raise PR for review once I add sufficient code and tested it)

Hello , Is this issue is available for Term 3 ?

Hello , Is this issue is available for Term 3 ?

Nope. This issue is well handled in the current term by @akshay196 and we anticipate to close it in this term itself.

But we will update the new issues that we intend to add to term 3 by today. Stay tuned.
