Usage

How to use this image

It behaves like a binary, so you can pass any arguments to the image and they will be forwarded to the sparklecoind binary:

$ docker run --name sparklecoind -d sparklecoin/sparklecoind \
  -rpcallowip=* \
  -rpcpassword=bar \
  -rpcuser=foo

Due to this you can use the same command to start the testnet container:

$ docker run --name sparklecoind-testnet -d sparklecoin/sparklecoind \
  -rpcallowip=* \
  -rpcpassword=bar \
  -rpcuser=foo \
  -testnet=1

By default, sparklecoin will run as as user coin for security reasons and with its default data dir (~/.sparklecoin). If you'd like to customize where sparklecoin stores its data, you must use the SPRK_DATA environment variable. The directory will be automatically created with the correct permissions for the coin user and sparklecoin automatically configured to use it.

$ docker run --env SPRK_DATA=/var/lib/sparklecoin --name sparklecoind -d sparklecoin/sparklecoind

You can also mount a directory it in a volume under /home/coin/.sparklecoin in case you want to access it on the host:

$ docker run -v /opt/sparklecoin:/home/coin/.sparklecoin --name sparklecoind -d sparklecoin/sparklecoind

That will allow to access containers ~/.sparklecoin directory in /opt/sparklecoin on the host.

$ docker run -v ${PWD}/data:/home/coin/.sparklecoin --name sparklecoind -d sparklecoin/sparklecoind

will mount current directory in containers ~/.sparklecoin

To map container RPC ports to localhost start container with following command:

$ docker run -v /opt/sparklecoin:/home/coin/.sparklecoin -p 6020:6020 -p 6021:6021 -p 16020:16020 -p 16021:16021 --name sparklecoind-testnet -d sparklecoin/sparklecoind -rpcallowip=* -testnet

You may want to change the port that it is being mapped to if you already run a sparklecoin instance on the localhost. For example: -p 9999:16021 will map port 16021 from container to localhost:9999.

Now you will be able to curl the sparklecoin RPC in the container:

curl --user bitcoin:password --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getinfo", "params": [] }' -H 'cont ent-type: text/plain;' docker inspect sparklecoind-testnet | grep -F ""IPAddress" | head -n1 | awk -F" '{print $(NF-1)}':16021/
