# Pantheon release grade Docker image
#
# What is this image for ?
#   This image is for using Pantheon within Docker for any purpose, test, dev, production.
#   The Docker file integrates two steps, first the build with a JDK and then the runnning image with a JRE.
#   Then you don't need a JDK installed locally to build Pantheon, just run the docker build
#   command and once the image is created you can use it as if you were using a regular Patheon binary.
#
# How to use this image:
#
#   first build it (use the name and tag you like) :
#
#   docker build -t mypantheon:myTag .
#
#   then run pantheon:
#   Either as a simple node with sync on mainnet with a volume for data (keeps the database between runs) and that's all:
#
#   docker run -d --mount source=pantheon_database,target=/opt/pantheon/database --name myPantheon mypantheon:myTag
#
#   or as a simple node with sync on mainnet with a volume for data (keeps the database between runs) and  HTTP/WS RPC access :
#
#   docker run -d --mount source=pantheon_database,target=/opt/pantheon/database \
#   --name myPantheon -p 8545:8545 -p 8546:8546 mypantheon:myTag \
#   --rpc-enabled --rpc-listen=0.0.0.0:8545 --rpc-cors-origins=mydomain.tld \
#   --ws-enabled -ws-listen=0.0.0.0:8546
