Connect on-prem ObjectServer to ObjectServer running in OCP on IBM cloud

    Hi,

    how do I connect an on-prem ObjectServer to an ObjectServer running in OCP on IBM cloud? Following the documentation at Configuring a uni-directional gateway and Connecting with the ObjectServer NodePort I wonder how about the "hostname" to put into the omni.dat file.

    Thanks and BR
    Dom

    Hi Dominic,

    there are a few scenarios possible:

    - Collection ObjectServers connected to Aggregation ObjectServer on OCP or

    - Visualization ObjectServers connected to Aggregation ObjectServer.

    In general you can connect both environments. It is explained here:

    Hi Fred,

    thanks for the quick reply. I'm aware of the documentation and chose "Configuring a uni-directional gateway". As stated above, the question I'm having is: How do I get the hostname that I should put into the omni.dat file? Where can I find it within OCP?

    Thanks and BR
    Dom

    Same way as described in the Going Hybrid video

    this is my sample omni.dat:


    You need to find the correct nodeports, this is explained after 4:50 in the video.

    Well, again, the node port is not my issue. I'm struggling with finding the hostname of my cluster and I think this part should be added to the documentation. When running this within OCP on IBM Cloud, a service configuration within OCP automatically creates a LB configuration in IBM cloud. Hence, the port should be available from the outside, tho I still don't know the hostname to use.

    The host name and mapping to an IP was defined during the installation.

    [netcool@batman etc]$ more /etc/hosts
    127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
    ::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

    Hi @Fred Harald Klein, where @Dominic Lehr is referring to is that when working with ROKS on VPC (instead of working with ROKS on "classic infrastructure", there's an additional layer in between the networking parts to get "WAN" traffic to land onto the actual Worker Nodes (within the VPC). You have the capability provided by the "Load Balancer for VPC" but you have to create them from INSIDE your ROKS cluster (what we didn't know) and not through the IBM Cloud interface (hence from OUTSIDE your ROKS cluster). Once this Load Balancer service was initiate from inside the ROKS cluster, both the primary & backup node_ports were exposed and successfully integrated with an on-premise Objectserver.

    Bottom-line: when talking about ROKS on IBM Cloud, please do make the distinction between ROKS on "classic infrastructure" versus ROKS on VPC.

    Have a lovely weekend!
