HydroShare Binder - Baseimage Example

This is an example for making a HydroShare resource \"Binder Capable\" by extending the HydroShare Ubuntu image. There are several advantages to using this base image: 1. Binder configurations can use Dockerfiles in addition to all other configuration files, e.g. apt.txt, requirements.txt, postbuild, etc. 2. The image is preinstalled with JupyterHub, Python3, and tools for accessing HydroShare data (e.g. iRODs, hs_restclient, nbfetch, and hstools) to facilitate interaction with the CUAHSI HydroShare.本示例演示了通过扩展HydroShare Ubuntu镜像，将HydroShare资源配置为支持Binder的形式。使用该基础镜像具备多项优势： 1. 除各类常规配置文件（如apt.txt、requirements.txt、postbuild等）外，Binder配置还可使用Dockerfile； 2. 该镜像预安装了JupyterHub、Python3以及用于访问HydroShare数据的各类工具（如iRODs、hs_restclient、nbfetch与hstools），以方便与CUAHSI HydroShare进行交互。
