Prior to R6, we accomplished this by configuring a NodePort service on the central site exposing the config-binding-service +http port (10000) and the https (10443) port. In R6, by default, we configure a ClusterIP service for config-service-service. This prevents the http port from +being exposed outside the central site Kubernetes Cluster._ + +_In addition, R6 changed how components get certificate for TLS. In prior releases, components that needed a certificate (a server certificate or just a CA certificate to use to validate servers) got the certificate using an init container (org.onap.dcaegen2.deployments.tls-init-container, version 1.0.3) that has +the certificates "baked in" to the container image. In R6, the init container (org.onap.dcaegen2.deployments.tls-init-container, version 2.1.0) executes code +that pulls a certificate from AAF. This will not work from a remote site because the necessary AAF services are not exposed there. We expect that work will +be done for R7 to remedy this._ + +_In the meantime, to use a remote, it will be necessary to deploy DCAE at the central site with these changes:_ + +_1. Override dcaegen2.dcae-config-binding-service.service.type. Set it to "NodePort", overriding the current setting of "ClusterIP"._ + +_2. Override global.tlsImage. Set it to "onap/org.onap.dcaegen2.deployments.tls-init-container:1.0.3". This will use the container with "baked in" certificates._ + +_3. Make sure all blueprints import "https://nexus.onap.org/service/local/repositories/raw/content/org.onap.dcaegen2.platform.plugins/R6/k8splugin/1.7.2/k8splugin_types.yaml",i.e., they need to use version 1.7.2 of the k8s plugin. (The blueprints loaded into inventory at deployment time currently meet this requirement._ + +_We expect significant changes to multi-site support in R7._ + +_Note that as of this update, there has been no testing of multi-site support in R6._ + ## Background Beginning with the ONAP Dublin release, DCAE allows for deploying data collection and analytics components into a remote site--specifically, into a Kubernetes cluster other than the central site cluster where the main ONAP and DCAE platform components are deployed. A proxy server is deployed into each remote cluster to allow components running in the remote cluster to access DCAE platform components in the central site. DCAE components running in a remote site can address platform components at the central site as if the platform components were running in the remote site. |
