Add e2e test for authorized pull/push

[vvoland]

Description

We need an e2e test that verifies that docker pull/push works for private repositories.

This would serve as an regression test for: #5963

#!/bin/bash

Configuration (replace with real values or use env vars)

DOCKER_REGISTRY="your-registry.com"
DOCKER_USERNAME="your-username"
DOCKER_PASSWORD="your-password"
IMAGE_NAME="private-image-e2e-test"
TAG="v1"
FULL_IMAGE="${DOCKER_REGISTRY}/${DOCKER_USERNAME}/${IMAGE_NAME}:${TAG}"

set -e # Exit immediately on error

echo "🔐 Logging in to Docker registry..."
echo "${DOCKER_PASSWORD}" | docker login "${DOCKER_REGISTRY}" -u "${DOCKER_USERNAME}" --password-stdin

echo "🐳 Creating a test image..."
echo -e "FROM alpine\nCMD echo Hello from e2e test!" > Dockerfile
docker build -t "${FULL_IMAGE}" .

echo "📤 Pushing the image to private registry..."
docker push "${FULL_IMAGE}"

echo "🧹 Removing local image to simulate pull..."
docker rmi "${FULL_IMAGE}"

echo "📥 Pulling the image from registry..."
docker pull "${FULL_IMAGE}"

echo "🚀 Running the pulled image..."
docker run --rm "${FULL_IMAGE}"

echo "✅ e2e test passed: push and pull successful!"

Optional cleanup

docker rmi "${FULL_IMAGE}"

docker logout "${DOCKER_REGISTRY}"
