Support cloud instances in 'Cluster state' panel

[ekazachkova]

Background Cloud Pipeline does not show cloud instance at Cluster State panel and it would be nice to support it.

Approach

• API shall support a new properties for cloud regions:

  • clusterInclude - flag that indicates that instances from this cloud region shall be included into Cluster state panel
  • clusterStateRegionProperties - object describes tag filters for instances that shall be shown (optional)

  {
    "tagsFilter": {
       "instanceTagKey": "instanceTagValue", ...
     }
  }
  

• API shall be able to manipulate both kubernetes nodes and cloud instances:

  • Load all API method GET /cluster/node/loadAll shall support an input parameter machineType=<KUBE|CLOUD|ALL>
    • KUBE - load kubernetes nodes only (default)
    • CLOUD - load cloud instances only from those regions where clusterInclude flag enabled.
    • ALL - load both kubernetes nodes and cloud instances
  • Loads node by name API method GET /cluster/node/<instance ID>/load shall support cloud instances and new input parameters
    • machineType=<KUBE|CLOUD|ALL> - default: KUBE
    • regionId (optional) - cloud region ID. If not provided all cloud regions with enabled clusterInclude flag will be scanned.
  • Terminate node by name API method DELETE /cluster/node/<instance ID> shall also support input parameters machineType (default: KUBE) and regionId (optional) and cloud instances termination.

• Returned node object shall contain:

  • a new field machineType
  • a label cloud_region_id

• AWS sdk methods shall be executed with timeout (this value can be configured via cluster.instance.load.timeout.seconds system preference)

• All actions with machineType=CLOUD shall be available for admin users only
