Docker - Security

After running:

docker run --cap-drop ALL --cap-add NET_ADMIN --cap-add CHOWN myimage

the container cannot modify network interfaces. What is the likely cause?

AThe CAP_CHOWN capability conflicts with CAP_NET_ADMIN

BThe container lacks the CAP_NET_RAW capability needed for network interface changes

CThe --cap-drop ALL removes all capabilities including those added later

DThe image does not support network modifications

Step-by-Step Solution

Solution:

Step 1: Analyze capabilities added
The command adds NET_ADMIN and CHOWN after dropping all.
Step 2: Understand network modification requirements
Modifying network interfaces often requires NET_RAW capability, which is not added here.
Step 3: Identify missing capability
Without NET_RAW, network interface changes fail despite NET_ADMIN.
Final Answer:
The container lacks the CAP_NET_RAW capability needed for network interface changes -> Option B
Quick Check:
Missing CAP_NET_RAW blocks network interface changes [OK]

Quick Trick: NET_ADMIN alone may not suffice; NET_RAW often required [OK]

Common Mistakes:

Assuming CAP_NET_ADMIN alone allows all network changes
Believing --cap-drop ALL removes added capabilities
Thinking CAP_CHOWN affects network capabilities
