Where is the Dockerfile written?

Dockerfile is a text file that defines how to build a Docker image. It contains a series of instructions that will build the image step by step.

Dockerfile is usually stored in the same directory as the Docker image code. Its name must be Dockerfile without any extension.

More detailed explanation:

Dockerfile can be placed anywhere as long as it is within the context of the Docker image code. However, best practice is to create it in the same directory as your code. This makes the build process easier to manage and more transparent.

Dockerfile must start with the "FROM" directive, specifying the base image to be based on. A subsequent series of instructions will gradually modify the base image, adding files, installing software, and configuring settings.

When you build a Docker image, the Docker engine reads the Dockerfile and executes the instructions contained within it. The end result is a complete Docker image defined by your Dockerfile.
