[Starlingx-discuss] StarlingX distributed cloud documentation for R3.0

[Sun, Austin]

Hi, Tao:
     Thanks a lot.
So , there are two phase :
     In Phase 1( bootstrap subcloud) ,  sub-cloud OAM is need to routed to central OAM. 
     In Phase 2(provision/manger subcloud)  mgmt. subcloud is need to routed to central cloud mgmt. network.

Thanks.

Hi Austin,

The subcloud bootstrapping interface can be any interface that has connectivity to the system controller.  The script we provided will configure the IP and route on the selected interface.

We recommended using the mgmt. interface previously because it would not require configuring OAM prior to bootstrapping, however, the mgmt. subnet would have to be a different subnet than the one that will be configured on the mgmt. interface after bootstrapping.  This means an 'additional temporary' IP address/subnet on mgmt. interface is required for bootstrapping.  

The decision to use the OAM interface and IP removes the requirement to allocate an 'additional temporary' IP address/subnet, and it is consistent with a NON-DC scenario.

See inline comments for your questions.

Hi Tao:
     Thanks your update .  which gerrit or patch enhances using OAM interface and IP to bootstrap the subcloud ?  has this patch already been merged ? 
TL> My document update changes network requirements and no code change is required.

     Another question , will OAM ip in subcloud L3 connection to OAM ip in central cloud ?  does it request mgmt ip in subcloud L2 connect to OAM ip in central cloud for V2? 
TL> Yes, OAM IP Subnets need to be routable between Central Cloud and Subclouds.  No, mgmt. ip in subcloud should not be connected to OAM ip in central cloud.

Thanks.

Thanks Arce!

A decision has been made to use OAM Interface and IP to bootstrap the subcloud. I have updated the document accordingly. The main change is to run the config_management script and enable OAM interface.

Hi Tao, Distributed Cloud team,

Here you have an early review of Distributed Cloud:
  https://review.opendev.org/#/c/689847/

We will take it as our base documentation and do the installation in our labs starting today, some changes likely coming. For now, please let us know if we need to add more people as Co-Authored-By.
