Introduction

This is a quick start guide aimed for non-technical users, to run a Radix DLT Betanet Emulator on your computer. The following steps are covered:

-Installing Docker
-Creating a configuration file
-Launching the Radix DLT Betanet Emulator

Emulator limitations

-The betanet emulator works in a stand-alone mode.
-There is no network or connection between nodes.
-Throughput is limited, as all workload is concentrated on a single node.
-Network API endpoints always return an empty set.

Pre-requisites

Hardware

Your host computer should have at least:

2 CPU cores
8 GB memory
20 GB disk

Note: the actual disk size requirement will grow over time as the ledger grows.

Software

You can run the Radix DLT Betanet Emulator on any operating system that supports Docker and Docker Compose, including:

-Linux
-MacOS X
-Windows 10

Installing Docker

You can download the right Docker Engine (Community Edition) for your system here: https://hub.docker.com/search/?type=edition&offering=community

For a detailed Docker setup guide, please refer to the official installation documentation for Docker CE.

Installing Docker Compose (Linux only)

If you are running Linux, after you completed the Docker setup you need to install Docker Compose. See the official Docker Composite installation guide for download links and additional information.

Tip: Docker Compose is bundled with Docker CE for the Mac and Windows versions.

Creating a configuration file

The Radix DLT software stack is composed of a single docker image, radixdlt/radixdlt-core-emulator:1.0.0-beta.
Your betanet-emulator.yml determines the software components you will run. In particular, the following settings are specified:

-The Docker image to download and start
-Persistent data volumes - that survive restarts and upgrades.

Start with this docker compose file:

version: '2.2'
services:
  core:
    image: radixdlt/radixdlt-core-emulator:1.0.0-beta
    init: true
    ports:

1.Create a directory on your computer for storing docker compose files (e.g., radixdlt).
2.Use your favorite text editor to create the betanet-emulator.yml.
3.Copy and paste the content above.

Launching the Betanet Emulator

Open up a Terminal (Mac/Linux) or a Command Prompt (on Windows). Navigate to the directory where you've placed your betanet-emulator.yml file. Launch the Docker containers with:

cd ~/radixdlt
docker-compose -p radixdlt -f betanet-emulator.yml up -d

If successful, it should pull down and look something like this when completed:

Creating network "radixdlt_single_node" with the default driver
Creating volume "radixdlt_core_ledger" with default driver
Creating volume "radixdlt_core_config" with default driver
Pulling core (radixdlt/radixdlt-core-emulator:1.0.0-beta)...

Creating radixdlt_core_1 ... done

Check that you have a radixdlt_core_1 Docker container with:

docker ps

You can also check if the Betanet Emulator is up and running at http://localhost:8080/api/system

If running correctly you should get a bunch of metrics - it should look something like this:

{"ledger":{"processed":0,"storingPerShard":0,"storedPerShard":":str:0.0","stored":1,"storing.peak":0,"latency":{"path":0,"persist":0},"checksum":9155064537244249607,"processing":0,"faults":{"tears":0,"assists":0,"stitched":0,"failed":0},"storing":0},"agent":{"protocol":100,"name":":str:/Radix:/2700000","version":2700000},"hid":":uid:8c0976a9ed622c4c0657f57a81c38f85","memory":{"total":2058354688,"max":2058354688,"free":1863937832},"nid":":uid:8cf1ffca3da4bcb3490067ad8e9273e4","serializer":"api.local_system","commitment":":hsh:0100000000000000000000000000000000000000000000000000000000000000","global":{"stored":1,"processing":0,"storing":0},"processors":2,"clock":1,"version":100,"planck":25853760,"shards":{"anchor":-8290564194929689421,"serializer":"radix.shard.space","range":{"high":8796093022207,"low":-8796093022208,"serializer":"radix.shards.range"}},"port":30000,"messages":{"inbound":{"processed":1,"discarded":0,"pending":0,"received":10},"outbound":{"processed":10,"aborted":0,"pending":0,"sent":10}},"events":{"broadcast":75,"processed":{"synchronous":64,"asynchronous":36},"queued":36,"processing":0,"dequeued":36},"key":":byt:A6rybyzH6BO3gp6XVA8NJdqAnL1FQMeCuJ8veFgM2mqQ","timestamp":1551225600000}

Congratulations, you are now successfully running the Betanet Emulator!

Managing the Betanet Emulator

Once you've got the Betanet Emulator running, you can stop or refresh (upgrade) the software using the following commands:

Stop the Betanet Emulator

docker-compose -p radixdlt -f betanet-emulator.yml down

Refresh the Betanet Emulator

docker-compose -p radixdlt -f betanet-emulator.yml pull

Kitematic

This is optional, but if you are running the Betanet Emulator on a Mac or Windows computer, you can download Kitematic to add a UI to your Docker container. If you want access to nice buttons and a live log view this is definitely for you!

Development libraries

Last, but not least, you can start your own DApp development using our Java and JavaScript client libraries.
