Quick Start - Step 1

Step 1 : Install RSK local node

RSK node can be installed on all major platforms, including Linux, Windows, and Mac. In this tutorial, we provide step-by-step instructions for running a local RegNet node through Docker. Docker installation supports Mac, Windows, and Linux.

Prepare the Environment

The tutorial project files can be downloaded from this github repo.

git clone https://github.com/rsksmart/truffle-integration
cd truffle-integration

For Mac OSX Developers:

Please ensure you are running xcode directly and not the command-line instance. Run

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer 

Install Docker Desktop Client

Docker Desktop provides an easy and fast way for running containerized applications on various of operating systems.

For Mac OSX and Windows:

  • Download and install
  • Start the Docker Desktop client
  • Login with a Docker Hub free account

For Linux:

Ensure that docker is running by running the following command - it should run without any errors.

docker ps

RSKJ Docker Images

Dockerfiles corresponding to the different environments can be downloaded from the RSK Artifacts page.

Next run the following commands to build the Docker images for each of the environments.

git clone git@github.com:rsksmart/artifacts.git
cd cd artifacts/Dockerfiles/RSK-Node/
docker build -t mainnet -f Dockerfile.MainNet .
docker build -t testnet -f Dockerfile.TestNet .
docker build -t regtest -f Dockerfile.RegTest .

The final line of output for each of the docker build commands should look similar to Successfully tagged regtest:latest.

Start RSKJ Container for a RegNet Node

For this quick start tutorial, we are going to use the RegTest docker

Run this command to build a RSKJ node for RegNet

cd <tutorial-root>/docker/
docker build -t regtest -f Dockerfile.RegTest .

Start a container with the built image. This command will start an RSKJ node with port 4444, 4445 and 30305 open.

docker run -d --name regtest-node-01 -p 4444:4444 -p 4445:4445 -p 30305:30305 regtest

If the container runs successfully, you should get an output that is a hash, for example: 2f75d6c3f08dc15232be42ed2dabcc370742b3dd573f45fcac7253abce151f9d.

You should be able to view the shell output for the container. Instead of the container ID, you may also use the hash that was output previously.

sudo docker container logs --follow regtest-node-01

You should see this in the logs: INFO success: rsk entered RUNNING state, process has stayed up for > than 1 seconds (startsecs). That indicates that an RSKJ node is running within this docker container.

Testing the nodes

RSK nodes allow you to connect over HTTP, whcih is exposed on port 4444. Let us verify that this works.

curl http://localhost:4444/1.1.0/ -X POST -H "Content-Type: application/json"     --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}'
{"jsonrpc":"2.0","id":1,"result":"0x2db0b"}

You can enter any valid JSON-RPC commands as the POST body.

The RSK nodes also allow you to connect over websockets, which are exposed on port 4445. Let us verify that this works too.

npx wscat -c ws://localhost:4445/websocket

If you have not installed wscat globally before, wait for it to do so, and then it will load up its own shell.

Connected (press CTRL+C to quit)
>

Again, you can enter any valid JSON-RPC command in the prompt. Be sure to check that you receive a valid and expected response.

> {"jsonrpc":"2.0","method":"eth_blockNumber", "params": [], "id":1}
< {"jsonrpc":"2.0","id":1,"result":"0x72"}

Cleaning up

After finishing the tutorial, you can use the following commands to shut down or remove the container.

docker container list
docker kill <container id>
docker rm <container id>

For the above example, <container id> is regtest-node-01.
