Why my docker-compose build is failing when copying files - docker

Question

I have a project that is running just fine using fastAPI (main.py). Now I want to share it as a docker image. Here is what I am doing:
My project has this structure:
project
│ docker-compose.yaml
| requirements.txt
│
└───<dir>services
│
└───<dir>api
| │ Dockerfile
| │ main.py
| |
| <dir>model
| file.model
| file.model
└───<dir>statspy
file.dev.toml
file.prod.toml
My Dockerfile:
FROM python:3.10
RUN pip install fastapi uvicorn transformers
COPY . /api /api/api
ENV PYTHONPATH=/api
WORKDIR /api
EXPOSE 8000
ENTRYPOINT ["uvicorn"]
CMD ["api.main:app", "--host", "0.0.0.0"]
docker_compose.yaml
version: "3"
services:
docker_model:
build: ./services/api
ports:
- 8000:8000
labels:
- "statspy.enable=true"
- "statspy.http.routers.fastapi.rule=Host(`fastapi.localhost`)"
topic_v5:
image: statspy:v5.0
ports:
- "80:80"
- "8080:8080"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:ro"
- "$PWD/services/statspy/statspy.dev.toml:/etc/statspy/statpys.toml"
when I run docker-compose build it fails with this error message:
Step 3/8 : COPY ./api /api/api
COPY failed: file not found in build context or excluded by .dockerignore: stat api: file does not exist
What am I doing wrong here?

Answer 1

Your build context in the docker-compose file is build: ./services/api
project
│ docker-compose.yaml
| requirements.txt
│
└───<dir>services
│
└───<dir>api <--- docker_model Dockerfile executes from here
| │ Dockerfile
| │ main.py
| |
| <dir>model
| file.model
| file.model
└───<dir>statspy
file.dev.toml
file.prod.toml
You later try to do COPY ./api /api/api. There is no api dir in /services/api, so the COPY directive fails.
What you probably want to do instead is COPY . /api. The rest of the Dockerfile looks correct.
