Prepare

Before you proceed, make sure you have Python 3 and pip3 installed.

On ubuntu, you can install with,

sudo apt update
sudo apt install python3 python3-pip python3-dev

⚠️ Upgrade pip if needed you are getting a Permission Denied error or version of pip (pip3 --version) is below 20.

pip3 install --upgrade pip

Install

⚠️ Make sure that you are installing with the --user flag.

pip3 install --user nearup

Verify that you local installation is in python3 -m site --user-base under bin directory by running:

which nearup

⚠️ If the above returns nothing, add nearup to your $PATH in ~/.profile, ~/.bashrc, or appropriate shell config.

USER_BASE_BIN=$(python3 -m site --user-base)/bin
export PATH="$USER_BASE_BIN:$PATH"

Upgrade

⚠️ If you have already installed nearup, you can upgrade to the latest version by using the command below

pip3 install --user --upgrade nearup

Getting Started

Using the official binary

This is recommended for running on servers

You can start your node with (remove the --interactive flag if you don't want to be prompted):

nearup run betanet --interactive

Replace betanet if you want to use a different network.

Using a locally compiled binary

Recommended for security critical validators or during development.

Clone and compile nearcore with make release or make debug first.

nearup run betanet --binary-path path/to/nearcore/target/{debug, release}

Replace betanet with testnet if you want to use a different network.

Spawn a local network

Clone and compile nearcore with make release or make debug first.

nearup run localnet --binary-path path/to/nearcore/target/{debug, release}

By default it will spawn 4 nodes validating in 1 shard. RPC ports of each nodes will be consecutive starting from 3030. Access one node status using http://localhost:3030/status

Operating

Stop a running node or all running nodes in local network

nearup stop

Additional options

nearup run betanet --help

Docker

Building the docker image

docker build . -t nearprotocol/nearup

Pull the docker image

If you don't want to build a docker image locally, you can pull the latest from Docker Hub,

docker pull nearprotocol/nearup

Running nearup with Docker

⚠️ nearup and neard are running inside the container, to ensure you don't lose your data which should live on the host you have to mount the ~/.near folder. To run the nearup docker image run:

docker run -v $HOME/.near:/root/.near -p 3030:3030 --name nearup nearprotocol/nearup run betanet

Running in detached mode

To run nearup in docker's detached (non-blocking) mode, you can add -d to the docker run command,

docker run -v $HOME/.near:/root/.near -p 3030:3030 -d --name nearup nearprotocol/nearup run betanet

Check if the container is running

docker ps

CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS           PORTS               NAMES

Execute nearup commands in container

To execute other nearup commands like logs, stop, run, you can use docker exec,

docker exec nearup nearup logs
docker exec nearup nearup stop
docker exec nearup nearup run {betanet/testnet}

(The container is running in a busy wait loop, so the container won't die.)

nearup logs

To get the neard logs run:

docker exec nearup nearup logs

or,

docker exec nearup nearup logs --follow

To get the nearup logs run:

docker logs -f nearup

Stop the docker container

docker kill nearup

Development

To build a development image:

docker build . -t nearprotocol/nearup:dev

The following will mount your repo directory into the running container and drop you into a shell to run test commands.

docker run -it --entrypoint "" -v $PWD:/root/nearup -v $HOME/.near:/root/.near -w /root/nearup nearprotocol/nearup:dev bash

Common commands

For testing and other checks, nearup uses tox.

To install,

pip3 install --user tox

Unit tests

tox

Unit tests w/ coverage

tox -e coverage

Linter checks

tox -e lint

Python style checks

tox -e style
