Level 6: Advanced Platform Engineering¶
Service mesh, GitOps, operators, policy engines, secrets management. The tools that turn a cluster into a production platform.
Concepts¶
service_mesh, gitops, k8s_operators, policy_engines, secrets_management, multi_tenancy, api_gateways, platform_engineering
Failure Patterns You Should Be Able to Resolve¶
All patterns from Levels 1-5, plus: - FP-016: Service mesh sidecar injection failures - FP-017: GitOps drift and sync loop failures - FP-018: Policy engine blocking legitimate workloads - FP-019: Secret rotation failures and expired tokens - FP-020: Operator reconciliation loops
Commands You Should Be Fluent With¶
All commands from Levels 1-5, plus:
- istioctl analyze, istioctl proxy-status, istioctl proxy-config (Service Mesh)
- argocd app sync, argocd app diff, argocd app get (GitOps)
- kubectl get crd, kubectl describe crd, operator logs (Operators)
- kubectl get clusterpolicy, kyverno test (Policy Engines)
- vault status, vault token lookup, vault kv get (Secrets)
