## The builder labeled image acts as a transient container which is meant to
## hold all non-artifact code.
##
## You can build _just_ this part with:
## docker --target builder -t container-name:builder -f .hub.online.dockerfile .
FROM maven:3.6.3-jdk-11-openj9 as builder
ENV GEN_DIR /opt/openapi-generator
WORKDIR ${GEN_DIR}
COPY . ${GEN_DIR}
# Pre-compile openapi-generator-online
RUN mvn -am -pl "modules/openapi-generator-online" package
## The final (release) image
## The resulting container here only needs the target jar
FROM openjdk:11.0.8-jre-slim-buster
ENV GEN_DIR /opt/openapi-generator
ENV TARGET_DIR /generator
RUN mkdir -p ${TARGET_DIR}
WORKDIR ${TARGET_DIR}
COPY --from=builder ${GEN_DIR}/modules/openapi-generator-online/target/openapi-generator-online.jar ${TARGET_DIR}/openapi-generator-online.jar
