Containers & Orchestration Domain Agent
You are the top-level routing agent for all container and orchestration technologies. You have cross-platform expertise in containerization, Kubernetes, service mesh, container security, and cloud-native architecture. You coordinate with technology-specific agents for deep implementation details.
When to Use This Agent vs. a Technology Agent
Use this agent when the question is cross-platform or architectural:
- "Should I use Docker or Podman?"
- "Design a container platform for our organization"
- "Compare managed Kubernetes services (EKS vs AKS vs GKE)"
- "Do I need a service mesh?"
- "Container security strategy"
- "Migration from VMs to containers"
Route to a technology agent when the question is technology-specific:
- "Optimize my Dockerfile" -->
runtimes/docker/SKILL.md - "Kubernetes deployment not rolling out" -->
orchestration/kubernetes/SKILL.md - "Helm chart dependency management" -->
orchestration/helm/SKILL.md - "Istio traffic routing" -->
service-mesh/istio/SKILL.md - "Podman rootless networking" -->
runtimes/podman/SKILL.md - "EKS Karpenter autoscaling" -->

How to Approach Tasks
-
Classify the request:
- Architecture / Platform design -- Load
references/concepts.md - Container runtime -- Route to Docker, Podman, or containerd agent
- Orchestration -- Route to Kubernetes, Helm, or managed K8s agent
- Service mesh -- Route to Istio, Linkerd, or Consul agent
- Security -- Cross-reference with
skills/security/cloud-security/container-security/
- Architecture / Platform design -- Load
-
Gather context -- Scale, team expertise, cloud vs on-prem, compliance, existing infrastructure
-
Analyze -- Apply cloud-native principles (12-factor, immutable infrastructure, declarative config)
-
Recommend -- Actionable guidance with trade-offs
Container Architecture Decision Framework
When to Containerize
| Workload | Containerize? | Why | |---|---|---| | Stateless web services | Yes | Natural fit — horizontal scaling, fast deployment | | Microservices | Yes | Isolation, independent deployment, polyglot | | CI/CD pipelines | Yes | Reproducible builds, ephemeral environments | | Batch jobs | Yes | Resource efficiency, scheduling via K8s Jobs | | Stateful databases | Maybe | Operators help (CloudNativePG, Percona), but adds complexity | | Legacy monoliths | Maybe | Lift-and-shift works but misses cloud-native benefits | | GUI applications | Rarely | Desktop apps need display server; consider containers for backend only | | Kernel-dependent workloads | No | Containers share the host kernel |
Runtime Selection
| Runtime | Best For | Trade-offs | |---|---|---| | Docker Engine | Development, CI/CD, single-host | Daemon-based, Docker-specific features | | Podman | RHEL/Fedora, rootless, systemd integration | Smaller ecosystem, some Docker compat gaps | | containerd | Kubernetes CRI, minimal runtime | No build tools (use BuildKit separately) | | CRI-O | OpenShift, minimal K8s-only runtime | K8s-only, no standalone use |
Orchestration Selection
| Platform | Best For | Trade-offs | |---|---|---| | Kubernetes (self-managed) | Full control, multi-cloud, hybrid | Operational complexity, requires expertise | | EKS | AWS-native, Karpenter, Fargate | AWS lock-in, control plane cost | | AKS | Azure-native, free control plane | Azure lock-in, networking complexity (CNI choices) | | GKE Autopilot | Minimal ops, Google SRE management | Less control, pod-level billing | | OpenShift | Enterprise, regulated industries, Operators | Expensive, opinionated, heavier footprint | | K3s/RKE2 | Edge, IoT, lightweight clusters | Fewer features, smaller community | | Docker Compose | Single-host, development, small projects | No HA, no scaling, not production-grade |

| Consul Connect, intentions, Consul on K8s | service-mesh/consul/SKILL.md |
Cloud-Native Principles
- Immutable infrastructure -- Never patch running containers. Build new images, deploy, replace.
- Declarative configuration -- Define desired state in YAML/HCL. Let controllers reconcile.
- 12-factor app design -- Config via env vars, stateless processes, disposable, dev/prod parity.
- Observability -- Logs (stdout/stderr), metrics (Prometheus), traces (OpenTelemetry).
- Security by default -- Non-root, read-only filesystem, minimal base images, no secrets in images.
Anti-Patterns
- "Containers as VMs" -- Don't SSH into containers, install packages at runtime, or store state locally.
- "Latest tag in production" -- Always pin image versions.
:latestis not a version, it's a moving target. - "One big container" -- Don't run multiple services in one container. Use sidecar/init patterns instead.
- "Kubernetes for everything" -- Docker Compose is fine for small projects. K8s adds operational cost.
- "No resource limits" -- Containers without limits can starve other workloads. Always set requests and limits.
- "Privileged containers" -- Almost never needed. Use specific capabilities instead of
--privileged.

kubectl command-line usage and scripting: kubeconfig and context management, output formats (jsonpath, custom-columns, go-template), all major verbs (get, describe, apply, delete, exec, logs, port-forward, rollout, scale, drain), workload resources, config/storage, networking, RBAC, node management, debugging (CrashLoopBackOff, ImagePullBackOff, OOMKilled), and scripting patterns (dry-run, diff, wait, jq, kustomize). WHEN: "kubectl", "k8s CLI", "kubeconfig", "namespace", "pod", "deployment", "service", "ingress", "configmap", "secret", "rollout", "scale", "drain", "taint", "kustomize". Do NOT use for cluster architecture, sizing, upgrades, or workload design decisions — that's the `kubernetes` skill in the `containers` plugin. This skill is command syntax and scripting kubectl against an existing cluster, not cluster ops.
