<PangolinCloudTocCta />

Blueprints let you define Pangolin resources as code. Instead of configuring every site, target, and access rule manually in the dashboard, you describe the desired state in YAML or container labels and let Pangolin apply it consistently.

Use blueprints when you want:

- Repeatable rollouts across many sites
- Version control for infrastructure and access settings
- A source of truth that can be reviewed, templated, and automated

<Note type="info">
Some features in this documentation are marked with **(EE)**, which means they require [Enterprise Edition](/self-host/enterprise-edition).
</Note>

## Blueprint Mental Model

A blueprint can contain up to three top-level sections:

- **`public-resources`**: Internet-facing HTTP, TCP, or UDP resources
- **`private-resources`**: Client-only access to hosts or CIDR ranges
- **`sites`**: Site-level settings such as container label discovery

```yaml
public-resources:
  <resource_key>:
    ...

private-resources:
  <resource_key>:
    ...

sites:
  <site_key>:
    ...
```

Think of the resource key as your stable ID inside the blueprint. The fields under that key describe what Pangolin should create or maintain.

## Choose A Format

Pangolin supports two blueprint formats:

### YAML

Use YAML when you want a readable file that can be committed to git, applied through Newt, pasted into the UI, or sent through the API.

### Container Labels

Use container labels when the resource definition should live inside your Compose stack. This is especially useful when a container and its Pangolin resource should be managed together.

## How YAML Blueprints Are Applied

<Card title="UI">
  Paste YAML into **Settings > Blueprints** in the Pangolin dashboard.

  <Frame>
    <img src="/images/create_blueprint.png" width="400" centered/>
  </Frame>
</Card>

<Card title="Newt">
  Run Newt with `--blueprint-file` to keep the file declarative and continuously applied:

  ```bash
  newt --blueprint-file /path/to/blueprint.yaml <other-args>
  ```

  If you only want a one-time bootstrap during provisioning, use [`--provisioning-blueprint-file`](/manage/sites/site-provisioning) instead.
</Card>

<Card title="API">
  Apply a blueprint through the Pangolin API with an API key. See the [API documentation](https://api.pangolin.net/v1/docs/#/Organization/put_org__orgId__blueprint).

  `PUT /org/{orgId}/blueprint`

  ```json
  {
    "blueprint": "base64-encoded-json-content"
  }
  ```

  [Python example](https://github.com/fosrl/pangolin/blob/dev/blueprint.py)
</Card>

<Card title="CLI">
  If your Pangolin CLI build includes blueprint commands, you can apply a file directly:

  ```bash
  pangolin apply blueprint --file /path/to/blueprint.yaml
  ```
</Card>

<Note>
`--blueprint-file` in Newt and container labels behave as an ongoing source of truth. Dashboard edits can be overwritten the next time the blueprint is applied. UI, API, and CLI applies are typically one-off operations.
</Note>

## Quick Start YAML Example

This example shows all three top-level sections in one file:

```yaml
public-resources:
  web-app:
    name: Web App
    protocol: http
    full-domain: app.example.com
    auth:
      sso-enabled: true
      whitelist-users:
        - admin@example.com
    targets:
      - site: my-site
        hostname: app
        port: 8080
        method: http
        healthcheck:
          hostname: app
          port: 8080
          path: /health

private-resources:
  ssh-host:
    name: SSH Host
    mode: host
    site: my-site
    destination: 192.168.1.10
    tcp-ports: "22"
    roles:
      - DevOps

sites:
  my-site:
    name: My Site
    docker-socket-enabled: true
```

## Public Resources

Public resources expose services through Pangolin.

- Use **`http`** for websites, APIs, and dashboards
- Use **`tcp`** or **`udp`** for raw public services bound to a port on the Pangolin server

### HTTP Resource Example

```yaml
public-resources:
  app:
    name: App
    protocol: http
    full-domain: app.example.com
    host-header: app.internal
    tls-server-name: app.internal
    headers:
      - name: X-Env
        value: production
    rules:
      - action: allow
        match: country
        value: US
      - action: deny
        match: path
        value: /admin
    auth:
      sso-enabled: true
      whitelist-users:
        - admin@example.com
    targets:
      - site: my-site
        hostname: app
        port: 8080
        method: http
```

<Note>
When applying a blueprint via Newt (using `--blueprint-file` or container labels), `site` on each target is optional. If omitted, the target is assigned to the site of the Newt that applied the blueprint.
</Note>

### Raw TCP Or UDP Example

```yaml
public-resources:
  mqtt:
    name: Mosquitto MQTT
    protocol: tcp
    proxy-port: 1883
    targets:
      - site: my-site
        hostname: mqtt-server
        port: 1883
```

For raw resources:

- `proxy-port` is required
- Target `method` must not be set
- `auth` is not supported

### Targets-Only Resources

A public resource can contain only `targets`. This is useful when you want to add or manage targets for an existing resource definition without repeating all resource-level fields.

```yaml
public-resources:
  extra-targets:
    targets:
      - site: secondary-site
        hostname: app-2
        port: 8080
        method: http
      - site: tertiary-site
        hostname: app-3
        port: 8080
        method: http
```

When a resource is targets-only, `name` and `protocol` are not required.

### Authentication Example

Authentication is configured inside `auth` and is supported only for HTTP resources.

```yaml
public-resources:
  secure-app:
    name: Secure App
    protocol: http
    full-domain: secure.example.com
    auth:
      pincode: 123456
      password: strong-password
      basic-auth:
        user: demo
        password: change-me
      sso-enabled: true
      sso-roles:
        - Member
      sso-users:
        - user@example.com
      whitelist-users:
        - admin@example.com
```

### Maintenance Page **(EE)**

The `maintenance` object lets you present a maintenance page for a public HTTP resource.

```yaml
public-resources:
  app:
    name: App
    protocol: http
    full-domain: app.example.com
    maintenance:
      enabled: true
      type: automatic
      title: Scheduled Maintenance
      message: We are upgrading the service.
      estimated-time: 2 hours
    targets:
      - site: my-site
        hostname: app
        port: 8080
        method: http
```

Maintenance `type` values:

- **`forced`**: Always show the maintenance page
- **`automatic`**: Show it only when all targets are unhealthy or the sites are offline

## Private Resources

Private resources define what Pangolin clients can reach after they connect to your organization.

- Use **`mode: host`** for a single host or DNS name
- Use **`mode: cidr`** for an entire network range

<Note>
When applying a blueprint via Newt (using `--blueprint-file` or container labels), `site` is optional. If omitted, the resource is assigned to the site of the Newt that applied the blueprint.
</Note>

```yaml
private-resources:
  internal-net:
    name: Internal Network
    mode: cidr
    destination: 10.0.0.0/24
    site: my-site
    tcp-ports: "22,443,8000-9000"
    udp-ports: "53,123"
    disable-icmp: false
    alias: "*.internal.example.com"
    roles:
      - Developer
    users:
      - user@example.com
    machines:
      - machine-id-1
```

## Container Labels Format

Container labels are the same blueprint schema flattened into dot-separated keys:

- Start every label with `pangolin.`
- Keep the same object path as YAML
- Use array indexes for lists, such as `[0]`

Example YAML:

```yaml
public-resources:
  my-app:
    headers:
      - name: X-Env
        value: prod
```

Equivalent Compose labels:

```yaml
labels:
  - pangolin.public-resources.my-app.headers[0].name=X-Env
  - pangolin.public-resources.my-app.headers[0].value=prod
```

<Note>
Container labels are continuously applied. Treat the Compose file as the source of truth because dashboard edits can be overwritten.
</Note>

### Enable Container Label Discovery

To use container labels, Newt must be able to read the Docker socket:

```bash
newt --docker-socket /var/run/docker.sock <other-args>
```

Or with an environment variable:

```bash
DOCKER_SOCKET=/var/run/docker.sock
```

### Docker Compose Example

```yaml
services:
  newt:
    image: fosrl/newt
    container_name: newt
    restart: unless-stopped
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - PANGOLIN_ENDPOINT=https://app.pangolin.net
      - NEWT_ID=h1rbsgku89wf9z3
      - NEWT_SECRET=z7g54mbcwkglpx1aau9gb8mzcccoof2fdbs97keoakg2pp5z
      - DOCKER_SOCKET=/var/run/docker.sock

  nginx1:
    image: nginxdemos/hello
    container_name: nginx1
    labels:
      - pangolin.public-resources.nginx.name=nginx
      - pangolin.public-resources.nginx.full-domain=nginx.fosrl.io
      - pangolin.public-resources.nginx.protocol=http
      - pangolin.public-resources.nginx.headers[0].name=X-Example-Header
      - pangolin.public-resources.nginx.headers[0].value=example-value
      - pangolin.public-resources.nginx.targets[0].method=http
      - pangolin.public-resources.nginx.targets[0].path=/path
      - pangolin.public-resources.nginx.targets[0].path-match=prefix

  nginx2:
    image: nginxdemos/hello
    container_name: nginx2
    labels:
      - pangolin.public-resources.nginx.targets[1].method=http
      - pangolin.public-resources.nginx.targets[1].hostname=nginx2
      - pangolin.public-resources.nginx.targets[1].port=80

networks:
  default:
    name: pangolin_default
```

This creates a single Pangolin resource with multiple targets:

  <img src="/images/docker-compose-blueprint-example.png" alt="Example resource"/>
</Frame>

### Container Label Behavior

<Card title="Automatic Discovery">
  If `hostname` or `port` are not set explicitly, Pangolin can detect them from the container configuration. The hostname typically defaults to the container name, and port detection is based on the container's `expose` configuration.
</Card>

<Card title="Site Assignment">
  If no `site` is specified on a target (public resource) or on a private resource, it is assigned to the site of the Newt that applied the blueprint — whether through container labels or `--blueprint-file`.
</Card>

<Card title="Merged Configuration">
  Labels from multiple containers can be merged into one logical resource, which is useful when different containers contribute different targets.
</Card>

## Validation Rules And Constraints

### Core Rules

1. A public resource can be **targets-only**. In that case it may contain only `targets`, and `name` plus `protocol` are not required.
2. When `protocol` is `http`, the resource must have `full-domain` and each target must include `method`.
3. When `protocol` is `tcp` or `udp`, the resource must have `proxy-port`, targets must not include `method`, and `auth` is not allowed.
4. `full-domain` values must be unique across public resources.
5. `proxy-port` values must be unique per protocol within `public-resources`. TCP `3000` and UDP `3000` can coexist, but two TCP resources cannot both use `3000`.
6. `alias` values must be unique across private resources in the blueprint.

### Common Validation Errors

### "Admin role cannot be included in sso-roles"

`Admin` is reserved and cannot be used in `auth.sso-roles`.

### "Duplicate 'full-domain' values found"

Every public HTTP resource must have its own unique `full-domain`.

### "Duplicate 'proxy-port' values found in public-resources"

Two public resources with the same protocol cannot reuse the same `proxy-port`.

### "When protocol is 'http', all targets must have a 'method' field"

Each HTTP target must specify `http`, `https`, or `h2c`.

### "When protocol is 'tcp' or 'udp', targets must not have a 'method' field"

Raw targets do not use HTTP methods.

### "When protocol is 'tcp' or 'udp', 'auth' must not be provided"

Authentication settings apply only to HTTP public resources.

### "Resource must either be targets-only or have both 'name' and 'protocol' fields"

Provide both fields for a full public resource definition, or remove everything except `targets`.

### "Duplicate 'alias' values found in private-resources"

Private resource aliases must be unique within the blueprint.

### "Destination must be a valid IP address or valid domain AND alias is required"

In `host` mode, the destination must be a valid host or IP. If you use a domain, provide `alias` as well.

### "Destination must be a valid CIDR notation for cidr mode"

In `cidr` mode, `destination` must be a valid CIDR block such as `10.0.0.0/24`.

### "Admin role cannot be included in roles"

`Admin` is reserved and cannot be used in private resource `roles`.
