Dockerfile命名，.dockerfile和Dockerfile

Question

I'm new to Dockerfile nomenclature and have noticed a few different examples of dockerfiles in repos throughout my org including the following types:

• Dockerfile
• Dockerfile.build
• .dockerfile

Is there somewhere I can find a detailed explanation for the different use cases and purposes of each?

Answer 1

docker build [OPTIONS] PATH | URL | - docker build [OPTIONS] PATH | URL | - This is the build command for docker, details here .

docker build command expects the file name as exactly Dockerfile . So, in that case, you can simply say

docker build .

On the other cases, you have to specify the full name as

docker build -f Dockerfile.build .

So the file name has nothing to do with the container itself. Those naming are for your own convenience.
