click on the Picture to see the optional Installation Deployments

the Software was shipped at time Friday, 20th of March, but you will not anymore see the Software in the software Marketplace (SMP), as the distribution was moved to a repository based channel (RBSC) as other Cloud based Software as well.

Upgrade to Version 3.0.32* (9th of June 2020)

SLPLUGIN00_49-70003322.EXE (slcb)

Repository 73554900100900004388

Blog - How to install SAP Data Intelligence 3.0 on-premise edition

SAP Data Intelligence 3.0 (aka as SAP Datahub 2.7.x) introduces an additional option to install the images on the Hyperscaler, i.e. Azure AKS with an own Installation Pod now.
the Setup of the SAP Hostagent is not necessary anymore, and the images will be written from the SAP Repository directly into the Container Registry of the connected AKS Cluster.

Note 2589449 - Software Lifecycle Container Bridge 1.0 (aka SL Plugin) - Release Note

the Blog mentions also now the usage of the slcb tool according to kubectl or helm.

initialize slcb to enable the container bridge

execute slcb with stack.xml provided by the Maintenance Planer

server:~ # slcb init -u web 

server:~ # slcb execute --useStackXML /sapmnt/SDH/MP/MP_Stack_1000907257_2020034_04032020.xml -u web

when you use the new slcb Bridge the first time, you will be asked twice for the Container Registry Address: one for the slcb tool itself and secondly for the Data Intelligence Product.

When you want to upgrade the slcb tool to a higher version, then you have to re-init the slcb tool, as the individual settings are overwritten by the tool upgrade. see also the Troubleshooting section.

Please choose your slcb hostname and port wisely. You may not use the default values.

to get to the correct option, you have to choose "Advanced Installation"

please Note that the Service Type "LoadBalancer is for Hyperscaler only, while the Service Type "NotePort" is for on-premise configurations like SuSE CaaSP.

Once the slcb tool is initialized, there is also a public IP created which can be configured (DNS label) you should use the latest Kubernetes Version, e.g. 1.15.10

server:~ # kubectl get pods -n sap-slcbridge

NAME                             READY   STATUS      RESTARTS   AGE

slcbridgehead-56bbf476d5-qdgq5   2/2     Running     0          7d3h

server:~ #  kubectl -n sap-slcbridge get service

NAME                    TYPE           CLUSTER-IP    EXTERNAL-IP      PORT(S)          AGE

slcbridgehead-service   LoadBalancer   <SLC Bridge Base IP>           1128:30701/TCP   7d3h

Default slcb URL: https://<SLC Bridge Base IP>:9000/docs/index.html
Example slcb URL: https://slcb-bridge.<region>.<area>.azure.com:443/docs/index.html
