Question

Accepted Answer

Explanation of Dockerfile, Docker Compose, and differences between them and Kubernetes.

Dockerfile is a script that contains instructions to build a Docker image.
Fields in Dockerfile include FROM, RUN, COPY, ADD, CMD, and more.
Docker Compose is a tool for defining and running multi-container Docker applications.
Docker Compose uses a YAML file to define services, networks, and volumes.
Kubernetes is a container orchestration platform that automates deployment, scaling, and management of containerized applications.
Kubernetes is more complex than Docker Compose but offers more advanced features.
ADD and COPY commands in Dockerfile are used to copy files into the image, but ADD can also download files from URLs and extract compressed files.
Docker Compose is better for simple applications, while Kubernetes is better for complex applications with high availability and scalability requirements.
