Resource Assignment =================== .. toctree:: :maxdepth: 1 Component executor: ------------------- Workflow: ~~~~~~~~~ A workflow defines an overall action to be taken for the service; it can be composed of a set of sub-actions to execute. Currently, workflows are backed by Directed Graph engine. A CBA can have as many workflow as needed. Template: ~~~~~~~~~ A template is an artifact. A template is parameterized and each parameter must be defined in a corresponding mapping file. In order to know which mapping correlate to which template, the file name must start with an artifact-prefix, serving as identifier to the overall template + mapping. The requirement is as follow: ${artifact-prefix}-template ${artifact-prefix}-mapping A template can represent anything, such as device config, payload to interact with 3rd party systems, resource-accumulator template, etc... Mapping: ~~~~~~~~ Defines the contract of each resource to be resolved. Each placeholder in the template must have a corresponding mapping definition. A mapping is comprised of: - name - required / optional - type (support complex type) - dictionary-name - dictionary-source Dependencies: ~~~~~~~~~~~~~ This allows to make sure given resources get resolved prior the resolution of the resources defining the dependency. The dictionary fields reference to a specific data dictionary. Resource accumulator: --------------------- In order to resolve HEAT environment variables, resource accumulator templates are being in used for Dublin. These templates are specific to the pre-instantiation scenario, and relies on GR-API within SDNC. It is composed of the following sections: resource-accumulator-resolved-data: defines all the resources that can be resolved directly from the context. It expresses a direct mapping between the name of the resource and its value. capability-data: defines what capability to use to create a specific resource, along with the ingredients required to invoke the capability and the output mapping. - Scripts - Library - NetconfClient In order to facilitate NETCONF interaction within scripts, a python NetconfClient binded to our Kotlin implementation is made available. This NetconfClient can be used when using the netconf-component-executor. The client can be find here: https://github.com/onap/ccsdk-apps/blob/master/components/scripts/python/ccsdk_netconf/netconfclient.py
