# HPE Morpheus Enterprise Blueprints

HPE Morpheus Enterprise App Blueprints allow pre-configured full multi-tier application deployments for multiple environments. Blueprints can be provisioned from the Provisioning > Apps section and can be fully configured for one click provisioning. Blueprints can be built within the `Builder` section or by code in the `Raw` section. Blueprints can also be exported as YAML or JSON and created with the HPE Morpheus Enterprise API and CLI.

A unique capability of the YAML/JSON based Morpheus blueprint structure is the ability to have multiple configurations per instance being provisioned within the app blueprint. This can be a scoped configuration that acts as overrides based on selected cloud, group, and/or environment the app is being provisioned in as a target. For example. maybe the “development” environment doesn’t need as many horizontally scaled nodes as the “production” environment. Another great aspect of this configuration markup is a blueprint can be defined as a hybrid cloud blueprint. This makes the app blueprint structure very powerful and in some ways better than alternative infrastructure as code orchestrators. For Example, ARM is locked into Azure, while CloudFormation is locked into AWS. Even Terraform does not allow a tf file to expand its bounds beyond a specific provider type.

## Basic Blueprint Structure

In a Morpheus App Blueprint there are a few structural concepts to be aware of. Firstly there is a concept of a Tier. A Tier is a grouping of instances within an app blueprint. Tiers can be used for a variety of things including sequenced booting of instances or even properly creating endpoint groups and security group contexts in network security tools like Cisco ACI. An example of a Tier structure might be a `Web` tier and a `Database` tier. These tiers can also be marked as connected such that network communication rules can appropriately be defined. A basic 2 Tier blueprint skeleton might look something like this:

```
```
name: Tier Example  
type: morpheus  
tiers:  
  Web:  
    linkedTiers:  
      - Database  
    tier:  
      bootOrder: 1  
    instances:  
  Database:  
    tier:  
      bootOrder: 0  
    instances:
```
```

This example has defined 2 tiers as yaml properties under the tiers object. They are called Web and Database. A Tier can optionally define its connected tiers which are bi-directional even though only one tier has to define them. This is the linkedTiers array and simply lists the connected tiers by tier name. A Boot Order can also optionally be defined under a nested `{"tier": {"bootOrder": 1}}` object structure.

## Configuration Scopes

Another capability of Morpheus App Blueprint structure is its configuration scoping. This allows properties to be overridden based on the apps target environment or even target group and cloud. For example. Maybe we want to use a larger plan size in production vs. development

An example of that can be done using “environments” overrides.

```
```
name: Simple Nginx  
type: morpheus  
tiers:  
  Web:  
    instances:  
      - instance:  
          type: docker  
          name: Sample Nginx  
        clouds:  
          AWS Cali:  
            instance:  
              layout:  
                code: docker-1.7-single  
            config:  
              dockerImageVersion: latest  
              dockerRegistryId: ''  
              dockerImage: nginx  
            plan:  
              code: container-128  
         environments:  
           Production:  
             groups:  
               All Clouds Demo:  
                 clouds:  
                   AWS Cali:  
                     plan:  
                       code: container-256
```
```

Note the new environments object. The object graph of the morpheus blueprint structure gets merged and flattened at provision time based on the scope of the configurations provided as well as the users target cloud, group, and environment selection. In the Above example, a selective override was done for the AWS Cali cloud when using a Production Environment and deploying to the group All Clouds Demo. This specific example changes the plan to a larger size. Scoped configurations have various levels of precedence. Cloud is the lowest level of precedence. a cloud configuration in a group is the next level higher and finally an environment configuration in a group in a cloud is the highest level of scoped precedence.

## Getting Started

To get started, it may be best to look at a simple App Blueprint configuration. Docker templates are less complex than virtual machine based templates so lets look at a Blueprint that deploys a single Nginx container to a target cloud:

```
```
name: Simple Nginx  
type: morpheus  
tiers:  
  Web:  
    linkedTiers: []  
    instances:  
      - instance:  
          type: docker  
          name: Sample Nginx  
        clouds:  
          AWS Cali:  
            instance:  
              layout:  
                code: docker-1.7-single  
                id: 206  
            volumes:  
              - rootVolume: true  
                name: root  
                size: 1  
            backup:  
              createBackup: false  
            config:  
              dockerImageVersion: latest  
              dockerRegistryId: ''  
              dockerImage: nginx  
            plan:  
              id: 68  
              code: container-128  
            ports:  
              - name: HTTP  
                port: 80  
                lb: HTTP
```
```

Theres some useful things to look at in the above docker example. One is there are different objects based on the different available configuration options for the target provision type. These options are actually data driven and can be extracted from the Inputs api in the morpheus api doc. That is a useful resource to look at while building morpheus blueprints or by using the morpheus-cli which provides prompts for helping build custom morpheus app blueprints.

## Creating Morpheus App Blueprints

### Procedure

1. Navigate to Library > Blueprints > App Blueprints
2. Select + ADD
3. Enter a NAME for the Blueprint and select NEXT
4. Optionally add a Description, Category, and Image for the Blueprint.

### Add Tiers

#### Procedure

1. In the STRUCTURE section, select + to add a Tier
2. Select or enter a Tier Name.
3. Select the Tier to set Boot Order, rename, or once multiple Tiers are added, connect the Tier to other Tiers.

### Add Instances to Tiers

#### Procedure

1. In the STRUCTURE section, select + in a Tier to add an Instance
2. Select an Instance Type
3. Optionally add a name for the Instance. Instances with blank names will automatically be named based off the App name.

#### Results

TIP

You can use the variable `${app.name}` in your instance naming convention to reference the name of the application you’re deploying.

### Add Configurations to Instances

#### Procedure

1. In the STRUCTURE section, select + in an Instance to add a Configuration
2. Select at least one option from Group, Cloud or Environment.
3. Select `ADD CONFIG` to create the configuration
4. Populate the Configuration 

   - Configurations can be fully partially or populated
   - Fields can be locked or hidden by selecting the Lock icon next to the Field. Locking prevents the field from being editable when provisioning an App using the Blueprint while hidden fields are not revealed to the user at all
   - ALLOW EXISTING INSTANCE will allow users to add existing Instances to the App when using the blueprint

### Save

Once all desired Tiers, Instances and Configurations are added, select Save. The Blueprint will be created, can be edited after saving, and will available in the Apps section for provisioning.

NOTE

Blueprints are not provisioned when created. To provision a Blueprint, use Provisioning > Apps.

### RAW

#### About this task

Blueprints can be create, edited or Exported in the RAW section when creating or editing a blueprint.

To Export a Blueprint as JSON or YAML:

#### Procedure

1. Navigate to Library > Blueprints > App Blueprints
2. Edit an existing App by clicking on the pencil icon
3. On the Edit Blueprint modal, select the Raw tab
4. Select YAML or JSON from the dropdown in the top right
5. Click the Export button
6. Select the configurations to include in the export by selecting or deselecting configurations as needed. Selected configurations will be highlighted
7. Click the DOWNLOAD CONFIGURATION button
8. The Blueprint export file will be downloaded to your computer as `{app_name}-config.json or {app_name}-config.yaml`

## Provisioning

To provision a Blueprint, navigate to Provisioning > Apps and select the Blueprint when creating an App. See the [App section](https://docs.morpheusdata.com/en/latest/provisioning/apps/apps.html) of HPE Morpheus Enterprise docs for more on provisioning Apps.
