Inspect a container's configuration
Read-only
What do risk levels mean?
- Read-only
- Inspects state without changing anything.
- Low risk
- Reversible with a routine follow-up command.
- Medium risk
- Changes state; undo path documented.
- Destructive
- Deletes or overwrites; confirmation required.
Shows a container's full configuration — image, environment, mounts, network settings, and restart policy — without changing anything.
dockerinspectconfiguration
Parameters
Container name or ID to inspect.
Commands
Show the container's complete configuration and state as JSON
docker inspect <container>Summarize the container's published port mappings
docker port <container>Verification
docker inspect <container>A JSON document describing the container; an error means no container by that name exists.
Undo
Not undoable
This recipe only reads configuration and changes nothing.
Pitfalls
- Environment variables in the output may contain sensitive values; avoid pasting the full JSON into shared channels.
- Works on stopped containers too; State.Status distinguishes running from exited.
