competition-container-runtime

Original：🇺🇸 English

Translated

Internal downstream skill for ctf-sandbox-orchestrator. CTF-sandbox workflow for live container runtime analysis, mounted secrets, sidecars, namespaces, init containers, entrypoint drift, and route-to-container resolution. Use when the user asks why a live container differs from manifests, where a mounted secret is consumed, how a sidecar or init container changes runtime state, or which route resolves to which live container. Use only after `$ctf-sandbox-orchestrator` has already established sandbox assumptions and routed here.

Competition Container Runtime

Use this skill only as a downstream specialization after

$ctf-sandbox-orchestrator

is already active and has established sandbox assumptions, node ownership, and evidence priorities. If that has not happened yet, return to

$ctf-sandbox-orchestrator

first.

Use this skill when the challenge is really about what the live container or pod is doing now, not what the checked-in manifest claims it should do.

Reply in Simplified Chinese unless the user explicitly requests English.

Quick Start

Split intent from reality: manifest, image, startup, live mount, live route, live process.
Map host -> proxy -> container or pod -> mounted volume -> consuming process.
Keep secrets, rendered config, init output, and sidecar output separate from static manifests.
Prove one minimal live path from mounted or injected state to reachable behavior.
Reproduce the effect with the smallest runtime-specific chain.

Workflow

1. Map The Live Runtime

Compare compose or kube manifests against running containers, pods, mounted volumes, env, sidecars, init containers, and entrypoints.
Identify which process actually consumes the mounted secret, rendered config, or shared volume output.

2. Trace Route And Mount Boundaries

Map virtual host, reverse proxy, service, container port, filesystem mount, and runtime-generated file paths together.
Record whether the decisive state is image-baked, env-injected, mounted later, or written by an init/sidecar process.

3. Report The Runtime Deviation

State the earliest point where live runtime diverges from checked-in intent.
Keep one compact evidence chain from manifest or compose intent to live consumer behavior.

What To Preserve

Compose/Kubernetes fragments tied to live mounts or routes
Container IDs, pod names, mount paths, sidecar outputs, rendered config paths, and consuming processes
The exact route or file path that becomes reachable only at runtime
