This template generates a Kubernetes init containers common template to enable applications to provision
- DMaaP feeds (on Data Router), with associated authorization.
- DMaap Bus Controller endpoints are used to provision:
-
- - Feed on DR, with associated user authentication.
+ DMaaP feeds (on Data Router) for DCAE microservices, with associated authorization.
+ DMaap Data Router (DR) endpoints are used to provision:
+ - Feeds on DR, with associated user authentication.
+ - Subscribers to feeds on DR, to provide DR with username, password, and URL needed to deliver
+ files to subscribers.
common.dmaap.provisioning.initContainer:
- This template make use of Dmaap Bus Controller docker image to create resources on Dmaap Data Router
- microservice, with the help of dbc-client.sh script it makes use of Bus Controller API to create Feeds.
- If the resource creation is successful via script response is logged back at particular location with
- appropriate naming convention.
-
- More details can be found at :
- (https://wiki.onap.org/pages/viewpage.action?pageId=103417564)
+ This template creates an initContainer with some associated volumes. The initContainer
+ (oom/kubernetes/dmaap-datarouter/drprov-client) runs a script (drprov-client.sh) that uses the
+ DR provisioning API to create the feeds and subscribers needed by a microservice. The script
+ updates the microservice's configuration to supply information needed to access the feeds. The
+ configuration information comes from two volumes that are created by the dcaegen2-services-common
+ templates.
+ - app-config-input: comes from a configMap generated from the microservice's values.yaml file.
+ It may contain references to environment variables as placeholders for feed information that
+ will become available after feeds are provisioned.
+ - app-config: this template will copy the configuration file from the app-config-input volume,
+ replaced the environment variable references with the actual values for feed information, based
+ on data returned by the DR provisioning API.
The template directly references data in .Values, and indirectly (through its
use of templates from the ONAP "common" collection) references data in .Release.
