NOTE: This is the discussion version of the Application Service Descriptor (ASD) onboarding IM. Please, refer to the released version 1.0 in the "Clean" wiki subfolder.
Introduction:
In today, many complex applications are consisting in a mixed, complex workload, that is described in many Kubernetes resources, e.g. to be run on a certain cluster, etc. In order to deploy the application, the orchestration task would be requiring dealing with different abstract layers of resources, different templates system mapping, and application packaging. Another challenge is to keep up with changes in the cloud infrastructures features enhancement mapping into abstract resource template.

Attribute | Qualifier | # | Content | Description |
deploymentItemId | M | 1 | Identifier | The identifier of this deployment item |
artifactType | M | 1 | String | Specifies the artifact type. One of following values can be chosen: "helm_chart", "helmfile", "crd", "terraform" |
artifactId | M | 1 | String | Reference to a DeploymentArtifact. It can refer to URI or file path. |
deploymentOrder | M | 0..1 | Integer | Specifies the deployment stage that the DeploymentArtifact belongs to. A lower value specifies that the DeploymentArtifact belongs to an earlier deployment stage, i.e. needs to be installed prior to DeploymentArtifact with higher deploymentOrder values. If not specified, the deployment of the DeploymentArtifact can be done in arbitrary order and decided bu by the orchestrator. |
lifecycleParameters | M | 0..N | String | The list of parameters that can be overridden at deployment time (e.g., the list of parameters in the values.yaml which can be overridden at deployment time) |
Note 1: All cloud native CNF resource IM is specified by particular cloud native specifications. K8s document is an example.

Note 2: The format of the Content strings is specific for each different orchestration templating technology used (Helm, Teraform, etc.). Currently only a format for use with Helm charts is suggested: "helmchartname<helmchartname>:[<subchartname>.]0..N[<parentparamname>.]0..N[<paramname>]”. Whether the optional parts of the format are present depends on how the parameter is declared in the helm chart. An example is: "chartName:subChart1.subChart2.subChart3.Parent1.Parent2.Parent3.parameter".
