Official Blocknet Docker Images

The docker images can be found on the docker hub: https://hub.docker.com/u/blocknetdx/

Servicenodes

By default the servicenode container runs without rpc capabilities -server=0.

Simple

Run a simple node on port 41412 without any servicenode capabilities.

docker run -d --name=snode -p 41412:41412 blocknetdx/servicenode:latest

Persist blockchain w/ volumes

Run a node that persists the blockchain on a host directory. Recommended to avoid time consuming resyncs when updating to later container versions.

docker run -d --name=snode -p 41412:41412 -v=/crypto/block/config:/opt/blockchain/config -v=/crypto/block/data:/opt/blockchain/data blocknetdx/servicenode:latest

Enable Servicenode (manually overridding config values)

When manually overridding the blocknetdxd command line arguments you must set -daemon=0 (blocking), otherwise the container will exit immediately. Using -daemon=0 will allow OS signals pass directly to blocknetdxd resulting in proper shutdowns (which will prevent corrupting the blockchain).

This command runs the container as a servicenode (do not use these exact values in production):

docker run -d --name=snode -p 41412:41412 blocknetdx/servicenode:latest blocknetdxd -daemon=0 -rpcuser=sn1 -rpcpassword=servicenode123 -servicenode=1 -servicenodeaddr=192.168.1.252 -servicenodeprivkey=1AqiKXiSZKf1BFQqqB2Mk3NVz7jFM2Za4r7eNzu3DWActGPeZ2L

Automatically restart the container

See https://docs.docker.com/engine/admin/start-containers-automatically/

--restart=no|on-failure:retrycount|always|unless-stopped

docker run -d --restart=no             --name=snode -p 41412:41412 blocknetdx/servicenode:latest blocknetdxd -daemon=0 -rpcuser=sn1 -rpcpassword=servicenode123
docker run -d --restart=on-failure:10  --name=snode -p 41412:41412 blocknetdx/servicenode:latest blocknetdxd -daemon=0 -rpcuser=sn1 -rpcpassword=servicenode123
docker run -d --restart=unless-stopped --name=snode -p 41412:41412 blocknetdx/servicenode:latest blocknetdxd -daemon=0 -rpcuser=sn1 -rpcpassword=servicenode123
docker run -d --restart=always         --name=snode -p 41412:41412 blocknetdx/servicenode:latest blocknetdxd -daemon=0 -rpcuser=sn1 -rpcpassword=servicenode123

Container shell access

docker exec -it snode /bin/bash

Default blocknetdx.conf

The default configuration is below. A custom configuration file can be passed to the servicenode container through the /opt/blockchain/config volume. Some of these parameters can also be adjusted on the command line.
