KubeArmor manual tests before releases

📄 Documenting KubeArmor release tests

The documentation provides the tests for KubeArmor which should be performed before creating a new KubeArmor release.

📜 Environment to be tested:

• BottleRocket - BPF-LSM
• GKE COS
  • Apparmor
  • BPF LSM

📜 Things to be tested:

🛡️ Enforcement - Apparmor, BPF-LSM

👀 Observability

Workload: wordpress-mysql Wordpress-mysql deployment
Security policies: KubeArmor/examples/wordpress-mysql/security-policies

For observability apply the respective policies and check karmor logs for corresponding logs.

• 🛑 Block policy - Expected alert + Block enforcement for the resource mentioned in the policy
• 🔍 Audit policy - Expected alert but no enforcement
• 👍 Allow policy - Expect alerts only for the resource(s) not mentioned in the policy
  • Default posture - If it’s set to audit (that’s default) then for an applied Allow policy, we shouldn't be blocking other processes, instead we should get Audit alerts

📈 Performance analysis:

Note down KubeArmor’s CPU and memory usages with and without load. (kubectl top)
This will help us in comparing KubeArmor’s performance among different releases.
