Unable to build Docker images due to missing Dockerfiles and Ubuntu base image pull error

[Clingto]

Thank you for your interesting and inspiring project!

I was trying to build and run the project locally, but I encountered some issues when building the Docker images.

---

💡 What I tried:

1. When I executed:

   docker image build -t loris-analyzer:python -f Dockerfile.python .

   I got:

   ERROR: failed to solve: failed to read dockerfile: open Dockerfile.python: no such file or directory
   

2. Similarly, when I ran:

   docker image build -t loris-analyzer:dev -f Dockerfile.dev .

   I received the same error:

   ERROR: failed to solve: failed to read dockerfile: open Dockerfile.dev: no such file or directory
   

3. When I tried the default Dockerfile with:

   docker image build -t loris-analyzer -f Dockerfile .

   I encountered the following error:

   ERROR: failed to solve: ubuntu:20.04: failed to resolve source metadata for docker.io/library/ubuntu:20.04: failed to do request: Head "https://registry-1.docker.io/v2/library/ubuntu/manifests/20.04": EOF

• It seems that Dockerfile.python and Dockerfile.dev are missing from the repository.
• The default Dockerfile does exist, but fails to pull the base image ubuntu:20.04.

---

My questions:

• Could you please confirm if Dockerfile.python and Dockerfile.dev are missing by design or accidentally omitted?
• Is the existing Dockerfile sufficient for building loris-analyzer or do we need the other Dockerfiles as well?

---

Thank you again for your great work and for sharing this project with the community!
Looking forward to your guidance.

I suspect — although I'm not certain — that Dockerfile.python and Dockerfile.dev are derived from the Dockerfile.
To reduce redundancy, it may be worth considering the use of hard links, along with corresponding entries in the .gitignore file to exclude .python and .dev files.
