Container Runtime

Build, run and isolate application images reproducibly.

Build against it

# give your agent the catalog — no account, no install
claude mcp add provespec -- npx -y provespec-mcp

# then, from any agent session
spec_get(slug: "container-runtime")                → the capability tree
spec_checklist(slug: "container-runtime")          → the questions to answer
spec_grade(slug: "container-runtime", grades: [...])  → parity % + the gap list

# or just fetch it
curl https://provespec.com/catalog/container-runtime/spec.json

Grade every capability below as yes · partial · no · na, with a file reference as evidence. Whatever you leave ungraded counts as missing — the gap list is the work queue.

Or just paste this to your agent

Use the ProveSpec MCP server. Fetch the "container-runtime" spec with
spec_get, then walk spec_checklist and grade this repository against it —
one verdict per capability, each with a file reference as the note.
Call spec_grade with the results and give me the gap list as the plan.

If the server is not registered, add it first:
  claude mcp add provespec -- npx -y provespec-mcp

The specification

Images
  • Build from a declarative file with cached layers
  • Layers are content-addressed and shared between images
  • Multi-stage builds so build tools stay out of the result
  • Multi-architecture images amd64, arm64
Registry
  • Push, pull and tag against a registry with auth
  • Image digests pin exactly, tags do not the reproducibility distinction
Runtime
  • Namespaced processes, filesystem and network
  • CPU and memory limits enforced
  • Read-only root filesystem and dropped capabilities available
  • Run as a non-root user
Storage
  • Volumes and bind mounts with explicit lifetimes
Networking
  • Port publishing and container-to-container networks
Lifecycle
  • Start, stop, restart policy, health check
  • Signals forwarded to PID 1 for graceful shutdown the zombie-process trap
Observability
  • Logs, stats and exec into a running container
Supply chain
  • Image scanning and signature verification
