This project is the starting point for the Security Profiles Operator (SPO), an out-of-tree Kubernetes enhancement which aims to make it easier for users to use SELinux, seccomp and AppArmor in Kubernetes clusters.
The motivation behind the project can be found in the corresponding RFC.
Related Kubernetes Enhancement Proposals (KEPs) which have direct influence on this project:
Next to those KEPs, here are existing approaches for security profiles in the Kubernetes world:
The SPO's features are implemented for each one of the underlying supported technologies, namely: Seccomp, SELinux and AppArmor. Here's the feature parity status across them:
| Seccomp | SELinux | AppArmor | |
|---|---|---|---|
| Profile CRD | Yes | Yes | Yes |
| ProfileBinding | Yes | No | No |
| Deploy profiles into nodes | Yes | Yes | Yes |
| Remove profiles no longer in use | Yes | Yes | Yes |
| Profile Auto-generation (logs) | Yes | WIP | No |
| Profile Auto-generation (ebpf) | Yes | No | No |
| Audit log enrichment | Yes | WIP | Yes |
For information about the security model and what permissions each features requires, refer to SPO's security model.
As any other piece of software, this operator is meant to help people. Thus, the target personas have been reflected in a document in this repo.
The functionality that this operator is meant to enable is captured as user stories. If you feel that a user story is not captured properly, feel free to submit a Pull Request. The team will be more than happy to review and help you reflect the requirement.
The project tries to not overlap with those existing implementations to provide valuable additions in a more secure Kubernetes context. We created a mind map to get a better feeling about all features we want to implement to better support some security areas within Kubernetes:
Going forwards, the operator will extend its purpose to assist Kubernetes users to create, distribute and apply security profiles for seccomp, AppArmor, SeLinux, PodSecurityPolicies and RBAC permissions.

We schedule a monthly meeting every last Thursday of a month.
