Dockerfile is not an extension, per default the file should be called Dockerfile for the build command to use it.

If you want to use a different name, though, the option -f or flag --file can help you achieve this.

docker build -t centos-redhat-8-beta -f centos-redhat-8-beta.dockerfile .

From the documentaion:

By default the docker build command will look for a Dockerfile at the root of the build context. The -f, --file, option lets you specify the path to an alternative file to use instead. This is useful in cases where the same set of files are used for multiple builds. The path must be to a file within the build context. If a relative path is specified then it is interpreted as relative to the root of the context.
