neo-privatenet-docker

Here we have provided a convenient way to setup a private Neo blockchain with an Ubuntu 16.04 docker image. Please review Dockerfile for details of software.

This image is meant to skip the overhead of having to wait to get enough gas for smart contract testing on testnet and to bypass the steps of creating your own private chain.

See the section below on extracting Neo and Gas as the private chain in this docker image starts at block height 0.

You will also need to install and configure the neo-gui pc client on your favorite distro. This involves editing the protocol.json file to point the seeds at your docker IP addresses.

Installation Instructions

git clone https://github.com/Splyse/neo-privatenet-docker.git
cd neo-privatenet-docker
./docker_build.sh
./docker_run.sh

or docker pull splyse/neo-privnet

Install neo-gui or neo-gui-developer

Install one of the following:

https://github.com/neo-project/neo-gui

https://github.com/CityOfZion/neo-gui-developer

Edit the protocol.json in your respective neo-gui installation to point to the IP of the system running your docker. Please note the ports listed match the private chain ports in the current docker build.

If you copy the protocol.json file from the configs directory of this repo and replace your neo-gui protocol.json you will only need to find and edit the section that looks like the following:

"SeedList": [
  "127.0.0.1:20333",
  "127.0.0.1:20334",
  "127.0.0.1:20335",
  "127.0.0.1:20336"
],

Change each occurrence of 127.0.0.1 to the IP of the system or vm running your docker image.

If you don't copy the protocol.json from the docker configs directory of this repo, in addition to the "SeedList" modifications mentioned above, you will also need to edit the following:

Change value "Magic" to 56753
Copy the public keys of each of your node wallets into the "StandbyValidators" section

Copy wallets from docker image to neo-gui

Once your docker image is running, use the following commands to copy each node's wallet to your neo-gui home directory in preparation for multiparty signature and neo/gas extraction. Note: all four must be copied.

The following will copy each wallet from the docker image to the current working directory.

 docker cp neo-privnet:/opt/node1/neo-cli/wallet1.db3 .
 docker cp neo-privnet:/opt/node2/neo-cli/wallet2.db3 .
 docker cp neo-privnet:/opt/node3/neo-cli/wallet3.db3 .
 docker cp neo-privnet:/opt/node4/neo-cli/wallet4.db3 .

Wallet Passwords

node1: one

node2: two

node3: three

node4: four
