Cloud-Init is the industry-standard tool for automating the initial bootstrapping of cloud and VPS instances. When you spin up a new server, Cloud-Init reads a user-data configuration file and executes setup tasks \u2014 creating users, installing packages, writing config files \u2014 before the system even becomes reachable via SSH. This guide walks through practical Cloud-Init configurations for production VPS deployments.<\/p>\n\n\n\n

What Is Cloud-Init and Why Use It?<\/h2>\n\n\n\n

Cloud-Init runs on the first boot of a VPS instance. It supports multiple input formats (YAML, shell scripts, cloud-config) and works with every major VPS provider. Instead of manually running apt update && apt upgrade<\/code> after provisioning, you define everything once in a Cloud-Init template and reuse it across deployments.<\/p>\n\n\n\n

Benefits include: reproducible server setups, reduced human error, faster provisioning, and a documented infrastructure-as-code approach. If you manage multiple VPS instances, Cloud-Init is the foundation for consistency.

Essential Cloud-Init Configurations<\/h2>\n\n\n\n

1. Basic Security Hardening<\/h3>\n\n\n\n

This cloud-config disables password authentication, creates a sudo user with your SSH key, and configures the firewall:<\/p>\n\n\n\n

#cloud-config\nusers:\n  - name: deploy\n    sudo: ALL=(ALL) NOPASSWD:ALL\n    shell: \/bin\/bash\n    ssh_authorized_keys:\n      - \"ssh-ed25519 AAAAC3... your-public-key\"\n\nssh_pwauth: false\ndisable_root: true\n\npackages:\n  - ufw\n  - fail2ban\n  - unattended-upgrades\n\nruncmd:\n  - ufw allow 22\/tcp\n  - ufw allow 80\/tcp\n  - ufw allow 443\/tcp\n  - ufw --force enable\n  - systemctl enable --now fail2ban<\/code><\/pre>\n\n\n\n
2. Web Server Bootstrap (Nginx + PHP + Let’s Encrypt)<\/h3>\n\n\n\n
#cloud-config\npackage_update: true\npackage_upgrade: true\n\npackages:\n  - nginx\n  - php-fpm\n  - php-mysql\n  - certbot\n  - python3-certbot-nginx\n  - mariadb-server\n  - redis-server\n\nwrite_files:\n  - path: \/etc\/nginx\/sites-available\/default\n    content: |\n      server {\n          listen 80 default_server;\n          server_name _;\n          root \/var\/www\/html;\n          index index.php index.html;\n          location \/ { try_files $uri $uri\/ =404; }\n          location ~ \\.php$ {\n              include snippets\/fastcgi-php.conf;\n              fastcgi_pass unix:\/run\/php\/php8.3-fpm.sock;\n          }\n      }\n\nruncmd:\n  - rm -f \/etc\/nginx\/sites-enabled\/default\n  - ln -s \/etc\/nginx\/sites-available\/default \/etc\/nginx\/sites-enabled\/\n  - systemctl enable --now nginx php8.3-fpm mariadb redis-server<\/code><\/pre>\n\n\n\n
3. Monitoring Stack Deployment (Prometheus + Node Exporter)<\/h3>\n\n\n\n
#cloud-config\npackages:\n  - prometheus-node-exporter\n\nruncmd:\n  - useradd --no-create-home --shell \/bin\/false prometheus\n  - cd \/opt\n  - wget https:\/\/github.com\/prometheus\/prometheus\/releases\/download\/v2.53.0\/prometheus-2.53.0.linux-amd64.tar.gz\n  - tar xvf prometheus-*.tar.gz\n  - mv prometheus-*\/ prometheus\/\n  - chown -R prometheus:prometheus \/opt\/prometheus\n  - cat > \/etc\/systemd\/system\/prometheus.service << EOF\n[Unit]\nDescription=Prometheus\nAfter=network.target\n\n[Service]\nUser=prometheus\nExecStart=\/opt\/prometheus\/prometheus --config.file=\/opt\/prometheus\/prometheus.yml\nRestart=always\n\n[Install]\nWantedBy=multi-user.target\nEOF\n  - systemctl enable --now prometheus<\/code><\/pre>\n\n\n\n
Testing Your Cloud-Init Configuration<\/h2>\n\n\n\n
Before deploying to production, validate your cloud-config locally:<\/p>\n\n\n\n
# Install cloud-init locally\nsudo apt install cloud-init\ncloud-init devel schema --config-file your-config.yaml<\/code><\/pre>\n\n\n\n
Most VPS providers let you paste the cloud-config YAML directly in their control panel or API. For providers that don't support Cloud-Init natively, you can append it as a post-install script via their provisioning API. Compare VPS providers with Cloud-Init support<\/a> to choose the right platform.<\/p>\n\n\n\n
