Overview

Package nodes provides information and interaction with the nodes through the OpenStack Clustering service.

Example to Create a Node 

opts := nodes.CreateOpts{
	ClusterID: "e395be1e-8d8e-43bb-bd6c-943eccf76a6d",
	Metadata:  map[string]interface{}{},
	Name:      "node-e395be1e-002",
	ProfileID: "d8a48377-f6a3-4af4-bbbb-6e8bcaa0cbc0",
	Role:      "",
}

node, err := nodes.Create(serviceClient, opts).Extract()
if err != nil {
	panic(err)
}

fmt.Printf("node", node)

Example to List Nodes 

listOpts := nodes.ListOpts{
	Name: "testnode",
}

allPages, err := nodes.List(serviceClient, listOpts).AllPages()
if err != nil {
	panic(err)
}

allNodes, err := nodes.ExtractNodes(allPages)
if err != nil {
	panic(err)
}

for _, node := range allNodes {
	fmt.Printf("%+v\n", node)
}

Example to Update a Node 

opts := nodes.UpdateOpts{
	Name: "new-node-name",
}

nodeID := "82fe28e0-9fcb-42ca-a2fa-6eb7dddd75a1"
node, err := nodes.Update(serviceClient, nodeID, opts).Extract()
if err != nil {
	panic(err)
}

fmt.Printf("%+v\n", node)

Example to Delete a Node 

nodeID := "6dc6d336e3fc4c0a951b5698cd1236ee"
err := nodes.Delete(serviceClient, nodeID).ExtractErr()
if err != nil {
	panic(err)
}

Example to Get a Node 

nodeID := "node123"
node, err := nodes.Get(serviceClient, nodeID).Extract()
if err != nil {
	panic(err)
}

fmt.Printf("%+v\n", node)

Example to Perform an Operation on a Node 

serviceClient.Microversion = "1.4"
nodeID := "node123"
operationOpts := nodes.OperationOpts{
	Operation: nodes.RebootOperation,
	Params:    nodes.OperationParams{"type": "SOFT"},
}
actionID, err := nodes.Ops(serviceClient, nodeID, operationOpts).Extract()
if err != nil {
	panic(err)
}

Example to Recover a Node 

nodeID := "b7b870e3-d3c5-4a93-b9d7-846c53b2c2da"
check := true
recoverOpts := nodes.RecoverOpts{
	Operation:     nodes.RebuildRecovery,
	Check:         &check,
}
actionID, err := nodes.Recover(computeClient, nodeID, recoverOpts).Extract()
if err != nil {
	panic(err)
}
fmt.Println("action=", actionID)

Example to Check a Node 

nodeID := "b7b870e3-d3c5-4a93-b9d7-846c53b2c2da"
actionID, err := nodes.Check(serviceClient, nodeID).Extract()
if err != nil {
