CLI Operations

# Install Northflank CLI
npm install -g @northflank/cli

# Login
northflank login

# Create a project
northflank create project my-app --region europe-west

# Deploy from Git
northflank create service my-app/api \
  --git-url https://github.com/myorg/my-api \
  --branch main \
  --port 3000 \
  --instances 2 \
  --plan nf-compute-20

# Add a database
northflank create addon my-app/main-db \
  --type postgresql \
  --version 16 \
  --plan nf-compute-20 \
  --storage 10240

# Manage secrets
northflank create secret my-app/api-secrets \
  --data '{"API_KEY": "sk-xxx", "JWT_SECRET": "xxx"}'

# Link secret group to a service
northflank link secret my-app/api --secret-group api-secrets

# View logs
northflank logs my-app/api --follow

# Scale service
northflank scale my-app/api --instances 5

Build Pipelines

# Northflank supports multiple build strategies:
# 1. Nixpacks (auto-detect, default)
# 2. Dockerfile
# 3. Buildpacks (Heroku/Cloud Native)
# 4. Pre-built Docker images

# Pipeline: Build → Test → Deploy
# Configure in dashboard or via API:
# 1. Source: GitHub/GitLab/Bitbucket webhook
# 2. Build: Nixpacks or Dockerfile
# 3. Preview: Auto-deploy PR branches
# 4. Production: Deploy on merge to main

Jobs and Cron

# Create a cron job
northflank create job my-app/daily-report \
  --type cron \
  --schedule "0 8 * * *" \
  --git-url https://github.com/myorg/my-api \
  --branch main \
  --run-command "node scripts/daily-report.js" \
  --plan nf-compute-10

# Create a manual job (triggered via API or dashboard)
northflank create job my-app/db-migrate \
  --type manual \
  --run-command "npx prisma migrate deploy"

Examples

Example 1: Setting up Northflank for a microservices project

User request:

I have a Node.js API and a React frontend running in Docker. Set up Northflank for monitoring/deployment.

The agent creates the necessary configuration files based on patterns like # Install Northflank CLI, sets up the integration with the existing Docker setup, configures appropriate defaults for a Node.js + React stack, and provides verification commands to confirm everything is working.

Example 2: Troubleshooting cli operations issues

User request:

Northflank is showing errors in our cli operations. Here are the logs: [error output]

The agent analyzes the error output, identifies the root cause by cross-referencing with common Northflank issues, applies the fix (updating configuration, adjusting resource limits, or correcting syntax), and verifies the resolution with appropriate health checks.

Guidelines

1. Use Infrastructure as Code — Define services in northflank.json; version with your repo for reproducible environments
2. Managed addons for databases — Don't self-manage Postgres/Redis/MongoDB; use Northflank addons with automatic backups
3. Secret groups for credentials — Group secrets by service; link them to deployments without hardcoding values
4. Preview environments for PRs — Enable branch-based previews; each PR gets its own URL and database
5. Health checks on every service — Required for zero-downtime deployments and automatic restart on failure
6. Use build caching — Northflank caches Docker layers and dependencies; structure your Dockerfile for optimal caching
7. Jobs for migrations — Run database migrations as manual jobs, not in the application startup sequence
8. Monitor build logs — Check build logs when deployments fail; most issues are dependency installation or build command errors
