## This base image is for running latest chainquery

LABEL MAINTAINER="leopere [at] nixc [dot] us"

## Install everything needed to unzip the file containing Chainquery
RUN apt-get update && \
    apt-get -y install unzip curl && \
    apt-get autoclean -y && \
    rm -rf /var/lib/apt/lists/* && \
    mkdir /download

## Download and extract the latest Zip containing Linux binary for Chainquery.
RUN curl -L -o /download/chainquery.zip $(curl -s https://api.github.com/repos/lbryio/chainquery/releases | fgrep 'Linux_x86_64.zip' | grep download | head -n 1 | cut -d'"' -f4) && \
    cd /download && \
    ls -lAh /download && pwd && \
    unzip chainquery.zip && \
    rm chainquery.zip

## TODO: Use this instead of everything above here at some point. To do this we will need the LBRY team to host all of their release binaries in their latest form internally I guess since github doesn't support latest tags.
