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 dynamicd binary:

$ docker run --name dynamicd -d syyyn84/dynamic \
  -rpcallowip=0.0.0.0/0 \
  -rpcpassword=bar \
  -rpcuser=foo

Use the same command to start the testnet container:

$ docker run --name testnet-dynamicd -d syyyn84/dynamic \
  -rpcallowip=0.0.0.0/0 \
  -rpcpassword=bar \
  -rpcuser=foo \
  -testnet=1

By default, dynamic will run as as user dynamic for security reasons and store data in /data. If you'd like to customize where dynamic stores its data, use the PPC_DATA environment variable. The directory will be automatically created with the correct permissions for the user and dynamic automatically configured to use it.

$ docker run --env DYNAMIC_DATA=/var/lib/dynamic --name dynamicd -d syyyn84/dynamic

You can also mount a host directory at /data like so:

$ docker run -v /opt/dynamic:/data --name dynamicd -d syyyn84/dynamic

That will allow access to /data in the container as /opt/dynamic on the host.

$ docker run -v ${PWD}/data:/data --name dynamicd -d syyyn84/dynamic

will mount the data sub-directory at /data in the container.

To map container RPC ports to localhost use the -p argument with docker run:

$ docker run -p 33350:33350 --name dynamicd -d syyyn84/dynamic -rpcallowip=*

You may want to change the port that it is being mapped to if you already run a dynamic instance on the host.

For example: -p 33350:3232 will map container port 9902 to host port 9999.

Now you will be able to curl dynamic in the container:

curl --user foo:bar --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "getblockchaininfo", "params": [] }' -H 'content-type: text/plain;' localhost:9902/
