Build, inspect, debug, and validate Docker or Podman images, containers, networks, volumes, and Compose stacks.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Container operations Use the available container runtime for reproducible builds, local stacks, diagnostics, and deployment validation. ## Workflow 1. Detect the available runtime and inspect the repository's container and Compose files before running commands. 2. Validate configuration, resolved environment, mounts, ports, health checks, and dependency ordering. 3. Build with explicit tags and capture build failures from the first relevant error. 4. Start the smallest required service set and wait on health rather than process existence. 5. Inspect service status, bounded logs, resource usage, networks, and volumes when diagnosing failures. 6. Exercise the exposed application endpoint and stop temporary resources when validation is complete. ## Safety - Confirm before pruning global images, builders, volumes, or networks. - Never print secret environment values or copy credential files into an image. - Prefer project-scoped cleanup over global cleanup. - Preserve persistent volumes unless the user explicitly requests deletion.

How to install
mdr add metaspartan/cybara/container-operations@sha256:c98b7305ecb3ba48The line at the top of this page pins the label git:20260718.df4aba6, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
