# Capabilities

# Deployment Capabilities

Deployment Capabilities are used to deploy a service on a resource. They can be added dynamically via the REST API of the Resource Registry. To simplify the use of the API the requests related to capabilites are available in the public Postman workspace (opens new window). The initial setup of Postman is described here.

# Import officially supported Deployment Capabilities

After installation, a new Service Lifecycle Management instance has no deployment capabilities. By default, the compose stack of the Service Lifecycle Management includes a service resource-registry-init. This service imports the officially supported capabilities during the first startup:

# Add a new Deployment Capability

Additional deployment capabilites can be imported using the endpoint POST /resources/capabilites of the Resource Registry. A request at the example of the Docker Deployment Capability (opens new window) looks like this:

ATTENTION

<<your-slm-host>> and <<your-keycloak-token>> (opens new window) must be replaced!

curl -X 'POST' \
  'http://<<your-slm-host>>:9010/resources/capabilities' \
  -H 'accept: application/json' \
  -H 'Realm: fabos' \
  -H 'Authorization: Bearer <<your-keycloak-token>>' \
  -H 'Content-Type: application/json' \
  -d '{

If a Deployment Capability is located in a private git repository, username and password / access token must be set for each action:

...
"actions": {

    "install": {

        "capabilityActionType": "install",
        "awxRepo": "https://my-private-git-repo/slm-dc-private",

        "playbook": "install.yml",
        "username": "myUser",
        "password": "myPassword"
      },
      ...
}

# Use deployment capability to deploy service offerings

To allow a deployment capability to deploy a service offering with a particular deployment type, that deployment type must be defined in the supportedDeploymentTypes property of the deployment capability. Currently, service offerings can have the following deployment types:

  • DOCKER_CONTAINER
  • DOCKER_COMPOSE
  • KUBERNETES
