Compiling Dockerfile

[Hektic130]

It looks like the Dockerfile is named dockerfile with a lowercase "d". Docker is case-sensitive, and it expects the file to be named exactly Dockerfile with an uppercase "D".

To fix this, you can either rename your existing Dockerfile to Dockerfile using the following command:

bash
mv dockerfile Dockerfile

It's possible to pass docker build a non-standard Dockerfile name.

docker build -f dockerfile .

However depending on the intentions of the project, it may make more sense to rename the file to Dockerfile within the project once and for all. 😁

I'd be glad to work on the Dockerfile a bit.
(In addition to the naming I think I've found some optimizations.)

Is there a reason it couldn't be renamed from dockerfile to Dockerfile (titlecase)?

Thank you!

Update: @Hektic130
I should have built an image the other day so I would have seen first hand that dockerfile (all lowercase) is picked up automatically by docker build. Maybe this changed in later Docker versions though I haven't found documentation of that.

Best I can see there's no mention in the Docker documentation for Dockerfiles of the support for all lowercase file name (instead of titlecase, but all lowercase works). 🤷‍♂️😁
