# Multi-stage build: First the full builder image:

# liboqs build type variant; maximum portability of image; no openssl dependency:
ARG LIBOQS_BUILD_DEFINES="-DOQS_DIST_BUILD=ON -DBUILD_SHARED_LIBS=ON -DOQS_USE_OPENSSL=OFF"

FROM alpine:3.16 as intermediate
# Take in all global args

RUN apk update && apk upgrade

# Get all software packages required for builing all components:
RUN apk add build-base linux-headers cmake ninja git

# get all sources
WORKDIR /opt
RUN git clone --depth 1 --branch main https://github.com/open-quantum-safe/liboqs && \

## second stage: Only create minimal image without build tooling and intermediate build results generated above:

RUN apk update && apk upgrade

# Get all software packages required for running all components:
RUN apk add python3 

# Only retain the binary contents in the final image
