Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
podman inspect --format='{{json .State.Health.Status}}' api_gw
Why this is correct
This inspect command uses a Go template to extract the exact health status string from the container state.
- ✗
podman health status api_gw
Why it's wrong here
podman health is not a top-level subcommand.
- ✗
podman ps --filter health=unhealthy
Why it's wrong here
While ps has filters, health checking filter syntax is different, and this does not provide a direct quick view of status like inspect formatting does.
- ✗
podman status api_gw
Why it's wrong here
podman status is not a valid command.
