Which of the following is the correct way to link an application container to an ambassador container in a Kubernetes pod YAML?
AUse separate pods for app and ambassador with no shared network.
BUse a Docker volume to share files between app and ambassador containers.
CDefine both containers under the same pod spec with shared localhost communication.
DExpose the ambassador container on a public IP address.
Step-by-Step Solution
Solution:

  1. Step 1: Understand pod container communication

    Containers in the same pod share the network namespace and can communicate over localhost.

  2. Step 2: Identify correct linking method

    Defining both containers in the same pod spec allows the app to talk to ambassador via localhost.

  3. Final Answer:

    Define both containers under the same pod spec with shared localhost communication. -> Option C

  4. Quick Check:

    Same pod = localhost communication [OK]
Quick Trick: Same pod containers communicate via localhost [OK]
Common Mistakes:
  • Thinking ambassador must be in a separate pod
  • Using volumes for network communication
  • Exposing ambassador publicly instead of internal proxy
