How to

Prerequisites

Before installing CP, ensure the following prerequisites are met:

• A public IP address is available

• The IP address has a bound domain name

• Go version 1.21+ is installed

• Multiple hosts with NVIDIA GPUs are prepared

---

Install Kubernetes

To deploy Kubernetes v1.25.3, follow this guide: https://blog.csdn.net/m0_43445928/article/details/130524917

Alternative: Deploy Kubernetes using your preferred method.

Register CP on Web Interface

1. Access Grid's official portal: https://grid.metamemo.one/

2. Navigate to Grid Provider section

3. Click Become A Provider

4. Complete registration form with:

   • Provider name

   • Public IP address

   • Service port

   • Domain name

Add Nodes via Web Interface

1. Go to Add Node page

2. Configure node parameters:

   Node Name Format: node-[number] (e.g., node-1)
   Pricing Strategy: Set your price per compute unit

3. Node ID Assignment Rule: Node ID = Node Name Number - 1 Example: node-1 → ID 0 node-5 → ID 4

---

Configure Kubernetes Node Labels

Step 1: Retrieve Node ID

Check node ID in web interface's node details page.

Step 2: Apply Labels

kubectl label node <NODE_NAME> id=<NODE_ID>

Example for node gpu-server-1 with ID 3:

kubectl label node gpu-server-1 id=3

Build & Configure CP Backend

1. Compile from Source

git clone https://github.com/gridprotocol/computing-api.git
cd computing-api/bin
make clean && make

2. Wallet Management

Import Existing Wallet

./computing-api wallet import \
  --sk=234fe73f5154570065a202f185dca074f1d7482a5e08ce093a92ed96807a6cf0 \
  --pw=123123

Create New Wallet

./computing-api wallet init --pw=STRONG_PASSWORD

Configuration File Setup

Edit computing-api/bin/config.toml:

# Network Configuration
[Grpc]
  Listen = "0.0.0.0:12345"  # gRPC service port

[Http]
  Listen = "0.0.0.0:12346"  # HTTP service port
  HSKey = "memo.io"          # Session encryption key
  CookieExpire = 86400       # 24h session validity

# Wallet Settings
[Remote]
  KeyStore = "./.keystore"    # Wallet storage path
  Wallet = "0xEf95c72C836605203F7f66788E450Af2a4141957"  # Your wallet address

# Infrastructure Endpoints
[Platform]
  Url = "http://183.240.197.189:18002"  # Production database URL

[Validator]
  Url = "http://validator.grid.io:8081"  # Validation service endpoint

---

Service Startup

Start Backend Service

# Syntax: ./restart.sh [chain_type]
./restart.sh test    # Testnet
./restart.sh dev     # Development
./restart.sh prod    # Production

Monitor Logs

tail -f log/computing-api.log | grep -E 'ERROR|WARN'

Verify Service Status

curl http://localhost:12346/healthcheck
# Expected response: {"status":"ok"}

Troubleshooting

Issue	Solution
Wallet import failure	Verify SK format and file permissions
Node label mismatch	Confirm kubectl context is correct
Blockchain RPC errors	Check network connectivity
