v1.0/english Dockerfile does not build

[agentydragon]

I get this output when trying to build the v1.0/english Docker image:

 $ docker build -f Dockerfile  -t english_spotlight .                                                                                             Sending build context to Docker daemon  4.608kB

Hey there, I also had the same problem.

It seems that the sourceforge urls provided inside the Dockerfile redirect to another page, which contains the file itself. So, all you have to do is to replace the urls with the redirected one. In my case, I changed the Dockerfile as follows:

FROM openjdk:8-jre-alpine

RUN apk add --no-cache curl && \
    mkdir -p /opt/spotlight  && \
    cd /opt/spotlight  && \
    curl -O "https://ufpr.dl.sourceforge.net/project/dbpedia-spotlight/spotlight/dbpedia-spotlight-1.0.0.jar"  && \
    curl -O "https://ufpr.dl.sourceforge.net/project/dbpedia-spotlight/2016-04/en/model/en_2+2.tar.gz"  && \
    tar xvf en_2+2.tar.gz   && \
    rm  en_2+2.tar.gz && \
    apk del curl

ADD spotlight.sh /bin/spotlight.sh
RUN chmod +x /bin/spotlight.sh
