Docker - Logging and Monitoring

You run docker events --filter event=start --filter container=web but receive no output when starting the container named web. What is the likely cause?

AThe docker daemon is not running

BThe event filter 'start' is invalid

CThe container name is incorrect or does not exactly match 'web'

DThe command requires sudo privileges

Step-by-Step Solution

Solution:

Step 1: Verify container name filter
If the container name filter does not exactly match the container's name, no events will be shown.
Step 2: Check other options
The docker daemon running is necessary but would cause errors if down. The 'start' event filter is valid. Sudo is not always required.
Final Answer:
The container name is incorrect or does not exactly match 'web' -> Option C
Quick Check:
No output usually means filter mismatch [OK]

Quick Trick: Ensure exact container name in filter to see events [OK]

Common Mistakes:

Assuming daemon is down without error
Thinking 'start' is invalid event
Believing sudo is always needed
