# DEPLODOCKER

### Why?
Poetry and others python dependency managers has no cozy interface to communicate with requirements.
Some of them has no methods for export extras or extras without main requirements.
Some of them has no possibilities to use another format excluding `requirements.txt`.
This project aims to fix this problem.
```dockerfile
FROM python:3.8-alpine AS base
RUN apk update
FROM base AS locker
ADD pyproject.toml .
RUN poetry lock
RUN deplodocker poetry.lock -i poetry -o requirements.txt -d requirements.txt \
&& deplodocker poetry.lock -i poetry -o requirements.txt -d requirements-main.txt -s main \
&& deplodocker poetry.lock -i poetry -o requirements.txt -d requirements-dev.txt -s dev \
&& deplodocker poetry.lock -i poetry -o requirements.txt -d requirements-raw.txt -s raw \
&& deplodocker poetry.lock -i poetry -o requirements.txt -d requirements-binary.txt -s binary \
&& deplodocker poetry.lock -i poetry -o requirements.txt -d requirements-debug.txt -s debug
FROM base AS builder_raw
COPY --from=locker /requirements-raw.txt .
### ...
FROM base AS builder_binary
COPY --from=locker /requirements-binary.txt .
### ...
```
