Answer: Build a container image with Docker, upload it to Google Container Registry, and deploy it to Kubernetes using kubectl.
The correct approach involves several key steps: 1. **Create a container image**: Use Docker to build an image from your Dockerfile, encapsulating all necessary components and dependencies for your web application. 2. **Push the image to Google Container Registry**: This step makes your container image accessible to Kubernetes by storing it in a registry. 3. **Deploy to Kubernetes with kubectl**: Utilize kubectl to deploy the image as a Kubernetes deployment. This requires a deployment manifest specifying the image, replicas, and other configurations. This method is widely recommended for deploying containerized applications to Kubernetes, offering advantages such as portability, scalability, and isolation.
