Source Index and Freshness

This skill was researched with GroktoCrawl against the following primary sources. The Compose Specification is the semantic authority; Docker documentation is the operational authority for Docker Compose CLI behavior.

Primary sources

• Docker Compose overview — purpose, lifecycle, and environments.
• Compose file reference — current field reference.
• Compose Specification — application model and syntax.
• Startup and shutdown order — dependency conditions and healthchecks.
• Networking — service DNS, ports, networks, and diagnostics.
• Interpolation — .env, --env-file, precedence, and syntax.
• Profiles — activation and dependency behavior.
• Compose Watch — sync, restart, rebuild, ignore rules, and permissions.
• Secrets — runtime and build secret injection.
• Merge — file order, path resolution, and merge classes.
• Compose CLI reference — command flags and lifecycle operations.
• Compose releases — implementation release history.

Source discipline

• Do not infer a feature's availability from a tutorial's publication date. Check release notes or the field's version marker.
• The Specification marks some attributes optional and platform-dependent. A file can parse while an implementation ignores part of it.
• Docker Compose CLI interpolation is not identical to every deployment target's interpolation; verify the target.
• Secondary tutorials are useful for worked patterns and failure stories, not for settling current syntax or compatibility.
