User Data Types

Choose the right format for your needs

cloud-config (YAML)

Declarative YAML. Users, packages, services, files, commands, runcmd. Full cloud-init spec supported.

Use case: Most configurations

Shell Script

Raw bash/sh. Runs as root at boot. Full system access. Shebang required.

Use case: Complex logic, custom installs

Template

Reusable templates with variables. {{ instance_id }}, {{ region }}, {{ project_id }}. Version-controlled.

Use case: Fleet standardization

Capabilities

Everything you need to bootstrap infrastructure

User Management

Create users, SSH keys, sudo access, groups. Lock root, enforce key-only.

Package Installation

apt, yum, dnf, apk, pip, npm. Pin versions. Private repo support.

Service Management

systemd units: enable, start, restart, mask. Custom unit files.

File Management

Create files, set permissions/owner, write content, append, templating.

Network Config

Static IPs, DNS, routes, firewall rules, interfaces. Netplan, ifupdown.

Disk & Filesystem

Partition, format (ext4/xfs/btrfs), mount, LVM, RAID, encryption.

Container Runtime

Docker, containerd, Podman. Images, networks, volumes, systemd services.

Kubernetes

kubeadm, k3s, RKE2. Join clusters, labels, taints, CNI, CSI.

Security Hardening

SSH config, fail2ban, auditd, AppArmor/SELinux, kernel params.

How It Works

From template to configured instance in seconds.

Create Template

Write cloud-config YAML or shell script. Use variables.

Version & Store

Git-backed. Tag releases. Rollback instantly.

Attach to Instance

Select template at launch. Variables auto-resolved.

Auto-Applied at Boot

cloud-init runs. Instance configured. Ready to use.

Infrastructure as Code for Boot

Your instance configuration lives in Git. Reviewed via PR. Tested in staging. Promoted to production. Same workflow as your application code.

And when you need help, our engineers are a Slack message away.
