Option to choose between CNS and CRS deployment methods. #43

Open ashmitha7 opened 6 years ago

ashmitha7 commented 6 years ago

I know the tool is called CNS Inventory creator. But in the README.md, it is mentioned for CNS and CRS. We should have an option to choose between CNS and CRS deployment methods. In the case of CRS, the glusterfs group and the glusterfs_registry in the inventory file will have the glusterfs_ip .
For example,

[glusterfs] dhcpxx-xx.lab.eng.blr.redhat.com glusterfs_devices='["/dev/sde", "/dev/sdf" ]' glusterfs_ip=10.70.xx.xx dhcpxx-xx.lab.eng.blr.redhat.com glusterfs_devices='[ "/dev/sde","/dev/sdf" ]' glusterfs_ip=10.70.xx.xx dhcpxx-xx.lab.eng.blr.redhat.com glusterfs_devices='[ "/dev/sde","/dev/sdf" ]' glusterfs_ip=10.70.xx.xx

[glusterfs_registry] dhcpxx-xx.lab.eng.blr.redhat.com glusterfs_devices='[ "/dev/xvdf" ]' glusterfs_ip=10.70.xx.xx dhcpxx-xx.lab.eng.blr.redhat.com glusterfs_devices='[ "/dev/xvdf" ]' glusterfs_ip=10.70.xx.xx dhcpxx-xx.lab.eng.blr.redhat.com glusterfs_devices='[ "/dev/xvdf" ]' glusterfs_ip=10.70.xx.xx

There is already an issue #30 opened , which is a similar request. @ashmitha7 @netzzer Does the calculations for Block hosting volume and total storage allocation be in the CRS scenario.

README.md updated to be more generic. Currently CIC support OCP 3.9 + CNS 3.9 and OCP 3.10 + OCS 3.10 converged mode (after OCS 3.10 is released). We will look to support OCP 3.9 + CRS 3.9 and OCP 3.10 + OCS 3.10 independent mode in the future (aka CRS 3.10).

Example of additional options for 3-5 nodes (1 gluster cluster). Add additional options to create heketi and glusterblock-provisioner pods on OCP and to create one CRS or OCS independent mode cluster. The inventory file options are EXACTLY the same for OCP 3.9 and OCP 3.10 for CRS/OCS independent mode.

Example of additional options for 6+ nodes (2 gluster cluster). Add additional options to create heketi (2) and glusterblock-provisioner(1) pods on OCP and to create two CRS or OCS independent mode cluster. The inventory file options are EXACTLY the same for OCP 3.9 and OCP 3.10 for CRS/OCS independent mode.

Also need to add 'glusterfs_ip' parameter for either 1 cluster, [glusterfs] only, or 2 cluster, [glusterfs] and [glusterfs_registry], as shown below. The glusterfs_ip should be the IP address of the gluster storage server (resolves to hostname) that will be used by heketi to create the gluster cluster.

[glusterfs] node11.example.com glusterfs_ip= glusterfs_devices='[ "/dev/xvdc", "/dev/xvdd" ]' node12.example.com glusterfs_ip= glusterfs_devices='[ "/dev/xvdc", "/dev/xvdd" ]' node13.example.com glusterfs_ip= glusterfs_devices='[ "/dev/xvdc", "/dev/xvdd" ]' node14.example.com glusterfs_ip= glusterfs_devices='[ "/dev/xvdc", "/dev/xvdd" ]'

[glusterfs_registry] node15.example.com glusterfs_ip= glusterfs_devices='[ "/dev/xvdc", "/dev/xvdd" ]' node16.example.com glusterfs_ip= glusterfs_devices='[ "/dev/xvdc", "/dev/xvdd" ]' node17.example.com glusterfs_ip= glusterfs_devices='[ "/dev/xvdc", "/dev/xvdd" ]'
