Docker - Logging and Monitoring

How can you monitor Docker events and save only container creation and destruction events to a file named events.log?

Adocker events --filter event=create --filter event=destroy | tee events.log

Bdocker events --filter event=create,destroy > events.log

Cdocker events --filter event=create --filter event=destroy > events.log

Ddocker events --filter event=create --filter event=destroy --output events.log

Step-by-Step Solution

Solution:

Step 1: Understand event filtering and output redirection
Multiple --filter event= flags filter create and destroy events. Output redirection with > overwrites file but does not show output.
Step 2: Evaluate options for saving and viewing output
docker events --filter event=create --filter event=destroy | tee events.log uses pipe to tee, which saves output to file and shows it live. docker events --filter event=create --filter event=destroy > events.log overwrites file but no live output. docker events --filter event=create,destroy > events.log uses invalid combined filter. docker events --filter event=create --filter event=destroy --output events.log uses unsupported --output flag.
Final Answer:
docker events --filter event=create --filter event=destroy | tee events.log -> Option A
