## 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.cli.dockerfile .
FROM jimschubert/8-jdk-alpine-mvn:1.0 as builder
RUN set -x && \
apk add --no-cache bash
ENV GEN_DIR /opt/openapi-generator
WORKDIR ${GEN_DIR}
COPY . ${GEN_DIR}
# Pre-compile openapi-generator-cli
RUN mvn -am -pl "modules/openapi-generator-cli" package
## The final (release) image
## The resulting container here only needs the target jar
## and ca-certificates (to be able to query HTTPS hosted specs)
