This is a quick consolidated tutorial on starting up a NEO private net with gas on your local Mac OSX with Docker and neo-python

Docker

Download and Install Docker Community Edition for Mac

Open Docker.app

Confirm it’s running in your taskbar

Click on the Docker icon in your taskbar and wait until the status shows a green circle with the message “Docker is running”, as shown in the image below

Open up a terminal window and type “docker run hello-world”

If the output is as shown above, your Docker installation was successful and can move on to the next step

Python 3.5

Check to see if your already have Python 3.5 installed. Open a terminal and type

python --version

If you see Python 2.7.X, try running

python3 --version

as you may have Python 2 and 3 installed on your system.

If you see Python 3.5.4 you are good to go, and can move onto the next step

If not, you can download and install Python 3.5.4

It’s important to note that neo-python is not compatible with Python 3.6, so please install version 3.5.4

LevelDB

Install using brew

brew install leveldb

neo-python

Pull down a local copy

git clone https://github.com/CityOfZion/neo-python.git

Navigate into the directory

cd neo-python

Create a virtual environment to install the project dependencies

python3 -m venv venv

source venv/bin/activate

The result should look similar to this

Install the project dependencies by running the following

pip install -U setuptools pip wheel

pip install -e .

It may take a while to install, but just wait for it to complete.

neo-privnet-with-gas

Pull the latest image from Docker hub

docker pull metachris/neo-privnet-with-gas

Start the container

docker run -d --name neo-privnet-with-gas -p 20333-20336:20333-20336/tcp -p 30333-30336:30333-30336/tcp metachris/neo-privnet-with-gas

Check to make sure the container is running

docker ps

Confirm setup

Navigate to your local neo-python directory if you aren’t already in there

Download the pre-made wallet

wget https://s3.amazonaws.com/neo-experiments/neo-privnet.wallet

Run

python prompt.py -c protocol.privnet.json

or, depending on your local python setup:

python3 prompt.py -c protocol.privnet.json

You should now be in the neo command line. This will be where you interact with your private neo net.

Open the pre-made wallet

open wallet neo-privnet.wallet

Enter the wallet password

coz

Check the wallet balance

wallet

The wallet should have the 100m NEO and ~60k GAS

Congrats! You are now officially set up, and have taken the first step on your way to start writing your own dapps and smart contracts!
