Templates

Deploy popular applications in seconds with sh0's template catalog. Browse 170+ pre-configured templates for databases, web frameworks, developer tools, and more.

Template Catalog

The template catalog is accessible from New App → Templates in any stack. Each template includes a pre-configured Docker image, default environment variables, volume mounts, and health checks -- everything needed to get a service running immediately.

Templates are searchable by name, category, or tag. You can also filter by category using the sidebar navigation.

One-Click Deploy

Deploying a template takes a single click. Select a template from the catalog, review the default settings, and hit Deploy. sh0 handles everything:

Pulls the Docker image from the configured registry
Creates named volumes for persistent data
Sets up environment variables with secure defaults (random passwords are generated automatically)
Configures health checks for the service
Provisions a domain at app-name.your-domain.com
Issues an SSL certificate via Caddy

One-click deploy confirmation screen for PostgreSQL with generated credentials

Tip

sh0 generates strong random passwords for every template that requires credentials. These are stored securely in the app's environment variables and are accessible from the dashboard.

Customizing Before Deploy

Before deploying, you can customize any template setting:

App name: Choose a name for your service (used in the URL)
Image tag: Select a specific version (e.g., postgres:16 vs postgres:15)
Environment variables: Override any default values
Resource limits: Set CPU and memory limits for the container
Volume size: Specify storage allocation for persistent data
Domain: Assign a custom domain instead of the default subdomain

Template customization form with fields for name, image version, environment variables, and resource limits

Note

All template settings can be changed after deployment. The customization screen simply lets you set initial values before the first deploy.

Creating Custom Templates

You can create your own templates to standardize deployments across your team. Custom templates are defined in YAML and can be added through the dashboard or placed in the templates/ directory on your sh0 server.

Custom templates placed in the templates/ directory are available to all users on your sh0 instance. You can organize them into subdirectories by category.

Tip

Custom templates appear alongside built-in templates in the catalog. They are visually distinguished with a "Custom" badge so your team can easily identify them.
