migration-patterns

A guide to moving applications from Kubernetes, Docker Compose, or Helm into Control Plane, a platform for running workloads.

In plain words
What is it for?
Use it to convert Kubernetes manifests, Compose files, or Helm charts, review the generated resources, and prepare the application for deployment.
Why use it?
It directs you to the correct converter for each source format and helps identify the configuration gaps that remain after automatic conversion.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

migration-patterns scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 171 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Migrating to Control Plane

Tool availability: some MCP tools named here live in the full toolset profile — if one is not advertised on this connection, tell the user to reconnect the MCP server with ?toolsets=full (or use the cpln CLI fallback). Reads work on every profile via the generic list_resources / get_resource tools; delete_resource is on every profile except readonly.

Each source format has its own converter, and they are not interchangeable: Kubernetes through cpln convert, Docker Compose through cpln stack, a Helm chart of Control Plane resources through cpln helm. All three are CLI-only — there is no MCP converter. The dominant failure is hand-translating a Compose/k8s/Helm artifact into Control Plane YAML — even one "small enough to do by hand" — instead of running the tool and then reviewing what it left behind. The converter gets the mechanical translation right; your value is the gap analysis on top of it. If asked to translate by hand, push back: convert first, then work through the fix-ups.

Pick the conversion path

Source Convert (CLI-only) One-shot deploy
Kubernetes manifests cpln convert -f k8s.yaml --gvc GVC cpln apply -f k8s.yaml --k8s true
Kubernetes Helm chart helm template R ./chart | cpln convert -f - --gvc GVC
Docker Compose cpln stack manifest --gvc GVC (preview) cpln stack deploy --gvc GVC
Helm chart of CPLN resources cpln helm install R ./chart --gvc GVC

cpln helm does not convert Kubernetes manifests — its charts must render only Control Plane kinds. There is no cpln stack convert; cpln stack manifest previews the generated YAML.

Kubernetes (cpln convert)

cpln convert -f FILE [--gvc GVC] reads a single file, a directory (recursive), or - for stdin, and writes Control Plane YAML. cpln apply -f FILE --k8s true runs the same converter and applies the result in one step. Resources that become their own Control Plane resource:

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

migration-patterns is a skill published in the GitHub repository controlplane-com/ai-plugin (10 stars, last pushed 8d ago), licensed MIT. It adds 50 tokens to every session and 3,970 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
