test-image

A minimal container image to verify Kubernetes imagePullPolicy: Always behavior.

The image prints a build-time value and then sleeps indefinitely, making it easy to confirm which image version actually ran.

Build

# Replace MY_VALUE with something unique (e.g., a timestamp or Git SHA)
docker build --build-arg BUILD_VALUE="MY_VALUE" -t myrepo/test-image:latest .

Run Locally

docker run --rm myrepo/test-image:latest

You should see MY_VALUE printed once, after which the container will keep running.

Deploy to Kubernetes

apiVersion: v1
kind: Pod
metadata:
  name: test-image
spec:
  containers:
  - name: test-image
    image: myrepo/test-image:latest
    imagePullPolicy: Always  # Ensure the image is always pulled

Update MY_VALUE and rebuild / push to verify that new pods pick up the latest image.
