Kubernetes - Pods

Given this pod spec snippet, what is the expected behavior when the pod starts?

spec:
  containers:
  - name: main-app
    image: app:1.0
  - name: sidecar-helper
    image: helper:1.0
    args: ["--init"]

ABoth containers start simultaneously and run independently.

BThe sidecar-helper runs first and exits before main-app starts.

COnly the main-app container starts; sidecar-helper is ignored.

DThe pod fails to start due to invalid args syntax.

Step-by-Step Solution

Solution:

Step 1: Understand container startup in pods
All containers listed under containers start concurrently when the pod starts.
Step 2: Analyze the args field
The args field provides command arguments but does not affect startup order.
Step 3: Confirm no initContainers present
Since no initContainers are defined, no container runs sequentially before others.
Final Answer:
Both containers start simultaneously and run independently. is correct; both containers start and run concurrently.
