Push To Cloud

Push to Cloud

You are an expert at deploying projects to the OCI-Dev cloud instance.

When To Use

• User says "Deploy this to cloud", "Push to OCI"
• User says "Run this externally", "Host this publicly"
• Project needs to run 24/7 outside homelab
• Lightweight Python/Node service needs cloud hosting

Homelab Alternative: For services running on homelab, consider using Tailscale Funnel + Cloudflare Worker instead. Simpler setup, no port forwarding, automatic HTTPS. See docs/public-access.md.

Target Machine: OCI-Dev

OCI Always Free Tier Limits

What CAN Be Deployed

• Lightweight Python APIs (FastAPI, Flask)
• Static sites / simple web apps
• Background workers / cron jobs
• Webhook receivers
• Chat bots (Telegram, Discord)
• Small databases (SQLite, Redis)

What Should NOT Be Deployed

• Heavy ML models (use homelab GPU)
• Large databases (PostgreSQL with big datasets)
• High-traffic production apps
• Anything requiring >4GB RAM per process

Prerequisites Check

ssh ubuntu@100.126.13.70 << 'CHECK'
echo "=== OCI-Dev Prerequisites ==="
python3 --version
pip3 --version
systemctl --version | head -1
df -h / | awk 'NR==2 {print "Disk: " $4 " available"}'
free -h | awk '/Mem:/ {print "RAM: " $4 " available"}'
CHECK

Quick Deploy Script

# Variables
PROJECT_NAME="my-project"
PORT="8080"
ENTRY_POINT="app.py"

# 1. Push code
rsync -avz --exclude='.venv' --exclude='node_modules' \
  --exclude='__pycache__' --exclude='.git' \
  ./ ubuntu@100.126.13.70:~/dev/${PROJECT_NAME}/

# 2. Setup on remote
ssh ubuntu@100.126.13.70 << REMOTE
cd ~/dev/${PROJECT_NAME}

# Create venv and install
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

# Create systemd service
sudo tee /etc/systemd/system/${PROJECT_NAME}.service > /dev/null << SERVICE
[Unit]
Description=${PROJECT_NAME}
After=network.target

[Service]
Type=simple
User=ubuntu
WorkingDirectory=/home/ubuntu/dev/${PROJECT_NAME}
ExecStart=/home/ubuntu/dev/${PROJECT_NAME}/venv/bin/python ${ENTRY_POINT}
Restart=always
RestartSec=5
Environment=PORT=${PORT}

[Install]
WantedBy=multi-user.target
SERVICE

sudo systemctl daemon-reload
sudo systemctl enable ${PROJECT_NAME}
sudo systemctl restart ${PROJECT_NAME}

# Verify
sleep 2
systemctl is-active --quiet ${PROJECT_NAME} && echo "✅ Running" || echo "❌ Failed"
REMOTE

Inputs Required

Outputs

• Project deployed to ~/dev/${PROJECT_NAME}/
• Systemd service running and enabled
• (Optional) DNS record created
• (Optional) Traefik config for HTTPS

Service Management

# Check status
ssh ubuntu@100.126.13.70 "systemctl status ${PROJECT_NAME}"

# View logs
ssh ubuntu@100.126.13.70 "journalctl -u ${PROJECT_NAME} -f"

# Restart
ssh ubuntu@100.126.13.70 "sudo systemctl restart ${PROJECT_NAME}"

# Stop
ssh ubuntu@100.126.13.70 "sudo systemctl stop ${PROJECT_NAME}"

Adding Public Domain (Optional)

1. Cloudflare DNS

curl -X POST "https://api.cloudflare.com/client/v4/zones/${ZONE_ID}/dns_records" \
  -H "Authorization: Bearer ${CF_TOKEN}" \
  -d '{"type":"A","name":"${SUBDOMAIN}","content":"100.112.130.100","ttl":1,"proxied":false}'

2. Traefik Config

Create ~/github/homelab/services/traefik/config/${PROJECT_NAME}.yml:

http:
  routers:
    ${PROJECT_NAME}:
      rule: "Host(`${SUBDOMAIN}.${DOMAIN}`)"
      entryPoints:
        - websecure
      tls:
        certResolver: cloudflare
      service: ${PROJECT_NAME}
  services:
    ${PROJECT_NAME}:
      loadBalancer:
        servers:
          - url: "http://100.126.13.70:${PORT}"

Rollback

# Stop and disable
ssh ubuntu@100.126.13.70 "sudo systemctl stop ${PROJECT_NAME} && sudo systemctl disable ${PROJECT_NAME}"

# Remove service file
ssh ubuntu@100.126.13.70 "sudo rm /etc/systemd/system/${PROJECT_NAME}.service && sudo systemctl daemon-reload"

# Remove project
ssh ubuntu@100.126.13.70 "rm -rf ~/dev/${PROJECT_NAME}"

Anti-Patterns

• Deploying without testing locally first
• Hardcoding secrets (use environment variables)
• Not checking if port is already in use
• Forgetting to restart Traefik after config change
• Deploying large apps (use homelab for heavy workloads)
