docker: Build a docker image using a specific Dockerfile.

docker

$ docker build --file ${Dockerfile} .

try on your machine

This command is used to build a Docker image based on a Dockerfile.

Let's break down the command:

docker build is the command used to build a Docker image.
--file specifies the Dockerfile to be used for the build process. In this case, ${Dockerfile} is a placeholder for the actual name of the Dockerfile. The ${Dockerfile} can be replaced with the actual filename, such as Dockerfile, dockerfile, or any other valid Dockerfile name.
. refers to the current directory where the build context is located. The build context consists of the files and directories needed to build the Docker image.

In summary, this command builds a Docker image using the specified Dockerfile in the current directory. The resulting image is ready for deployment as a container.
