Build and Run Delta

Prepare to build

Copy the .env.example file to .env and update the values as needed.

# Node info
NODE_NAME=stg-deal-maker
NODE_DESCRIPTION=Experimental Deal Maker
NODE_TYPE=delta-main

# Database configuration
MODE=standalone
DB_DSN=delta.db
#REPO=/mnt/.whypfs # shared mounted repo

# Frequencies
MAX_CLEANUP_WORKERS=1500

Install and run Delta using docker

Running this the first time will generate a wallet. Make sure to get FIL/DataCap from the faucet and fund the wallet

Make sure you have docker installed on your machine.

Run the current delta clone using docker-compose

If you already have a wallet with datacap, you can pass it to the command below. This copies over the wallet directory to the containerized app and sets it as the default wallet.

make docker-compose-run WALLET_DIR=<walletdir>

Check localhost

You can check the localhost to see if the delta app is running

curl --location --request GET 'http://localhost:1414/open/node/info'

Next

Now that you can access a live Delta node, you are now ready to make a deal. You can now go to the following guides:

• Make an e2e deal
• Make an import deal

Run a specific docker image tag from the docker hub artifactory

We have a few pre-built images on the docker hub artifactory. You can run the following command to run a specific image tag

cd docker
./run.sh <TAG> 

Note: no tag means it'll just get the latest image.

Install, build from source and run Delta

Install the following pre-req

• go 1.19
• jq
• hwloc
• opencl
• rustup
• postgresql

Alternatively, if using Ubuntu, you can run the following commands to install the pre-reqs

apt-get update && \
apt-get install -y wget jq hwloc ocl-icd-opencl-dev git libhwloc-dev pkg-config make && \
apt-get install -y cargo

Using make

make all
./delta daemon --repo=.whypfs --wallet-dir=<walletdir>

Using go build

go build -tags netgo -ldflags '-s -w' -o delta
./delta daemon --repo=.whypfs --wallet-dir=<walletdir>

Run Delta

./delta daemon --mode=standalone

Test the API server

Try the following endpoints to test the API server

curl --location --request GET 'http://localhost:1414/open/node/info'
curl --location --request GET 'http://localhost:1414/open/node/peers'
curl --location --request GET 'http://localhost:1414/open/node/host'

If it return the following, then the API server is working

{"name":"stg-deal-maker","description":"Experimental Deal Maker","type":"delta-main"}
