# 1. Build the image with: docker build --no-cache -t test/vaadinplus:latest --build-arg offlinekey='key' .
# 2. Run the image with: docker run --rm -ti -p8080:8080 test/vaadinplus
#
# Uses Docker Multi-stage builds: https://docs.docker.com/build/building/multi-stage/

ARG offlinekey
ENV VAADIN_OFFLINE_KEY=$offlinekey
RUN ./mvnw clean test package -Pproduction -Dvaadin.skip.dev.bundle=true
