Build and Run Ajuna and worker

Building

Clone the projects and mount them in a container:

git clone -b polkadot-v0.9.20-dev [email protected]:ajuna-network/Ajuna.git Ajuna
git clone [email protected]:ajuna-network/worker.git worker
cd worker && git checkout 0c40097 && cd ..

Run Ajuna and worker

Run compose with optinal logging (open http://localhost in your browser for app):

docker-compose up -d
docker logs ajuna-network_worker_1 -f

Bash into the worker container to start sending trusted calls:

Running a Substrate-based blockchain node

• Prerequisite reading
  • Start a private network tutorial - just read the below sections (there's no need to read the whole thing)
    • Start the blockchain using predefined accounts
      • I have read and run node locally
      • I understand the command-line options (particularly --node-key, --bootnodes and the different ports used)
    • Create a custom chain specification
      • I understand the process of generating chain specs
• Launch the private network
