Step-by-Step Solution
Solution:
Step 1: Understand filter syntax for multiple events
Multiple --filter event= flags can be used separately for start and stop events.Step 2: Understand container filter limitations
Docker events 'container' filter supports prefix matching for container names and IDs; wildcards like 'db*' are not supported.Step 3: Evaluate options
docker events --filter 'event=start' --filter 'event=stop' --filter 'container=db' correctly uses two event filters and a container prefix filter 'db'. docker events --filter event=start --filter event=stop --filter name=db uses invalid 'name' filter key, providing no container filtering. docker events --filter 'event=start,stop' --filter container=db uses invalid combined event filter. docker events --filter 'event=start' --filter 'event=stop' --filter 'container=db*' uses unsupported wildcard.Final Answer:
docker events --filter 'event=start' --filter 'event=stop' --filter 'container=db' -> Option BQuick Check:
Multiple filters allowed; container filter exact match only [OK]
Quick Trick: Use multiple --filter event= flags; container filter needs exact name [OK]
Common Mistakes:
- Using wildcards in container filter
- Combining multiple events in one filter
- Assuming container filter supports partial names
