+# /************************************************************************
+ #  File: Dockerfile
+ #  Author: mdr0id
+ #  Date: 9/3/2019
+ #  Description:  Used for devs that have not built zcash or lightwalletd on
+ #                on existing system
+ #  USAGE:
+ #
+ #  To build image: make docker_img
+ #  To run container: make docker_image_run
+ #  
+ #  This will place you into the container where you can run zcashd, zcash-cli, 
+ #  lightwalletd ingester, and lightwalletd server etc..
+ #
+ #  First you need to get zcashd sync to current height on testnet, from outside container:
+ #  make docker_img_run_zcashd
+ #
+ #  Sometimes you need to manually start zcashd for the first time, from insdie the container:
+ #  zcashd -printtoconsole   
+ #
+ #  Once the block height is atleast 280,000 you can go ahead and start lightwalletd components
+ #  make docker_img_run_lightwalletd_ingest
+ #  make docker_img_run_lightwalletd_insecure_server
+ #  
+ #  If you get kicked out of docker or it locks up...
+ #  To restart, check to see what container you want to restart via docker ps -a
+ #  Then, docker restart <container id>
+ #  The reattach to it, docker attach <container id>
+ #
+ #  Known bugs/missing features/todos:
+ #
+ #  *** DO NOT USE IN PRODUCTION ***
+ #  
+ #  1. Create docker-compose with according .env scaffolding 
+ #  2. Setup container volume for blocks dir; remove sync time
+ #  3. Determine librustzcash bug that breaks zcashd alpine builds at runtime
+ #  4. Once versioning is stable add config flags for images
+ #  5. Add mainnet config once lightwalletd stack supports it 
+ #
