# Build a docker image from latest YaCy sources

# Base image : latest stable official jdk image from Docker (Debian based) 
FROM java:latest

# Install needed packages not in base image
RUN apt-get update && apt-get install -yq curl
	
# trace java version
RUN java -version
	
# set current working dir
WORKDIR /opt

# All in one step to reduce image size growth :
# - install ant and git packages
# - clone main YaCy git repository (we need to clone git repository to generate correct version when building from source)
# - Compile with ant
# - remove unnecessary and size consuming .git directory
# - remove ant and git packages
RUN apt-get update && \
	apt-get install -yq ant git && \
	git clone https://github.com/yacy/yacy_search_server.git && \
	ant compile -f /opt/yacy_search_server/build.xml && \
	rm -rf /opt/yacy_search_server/.git && \
	apt-get purge -yq --auto-remove ant git && \ 
	apt-get clean
