Overview

Package clusters contains functionality for working with Magnum Cluster resources.

Example to Create a Cluster 

masterCount := 1
nodeCount := 1
createTimeout := 30
masterLBEnabled := true
createOpts := clusters.CreateOpts{
	ClusterTemplateID: "0562d357-8641-4759-8fed-8173f02c9633",
	CreateTimeout:     &createTimeout,
	DiscoveryURL:      "",
	FlavorID:          "m1.small",
	KeyPair:           "my_keypair",
	Labels:            map[string]string{},
	MasterCount:       &masterCount,
	MasterFlavorID:    "m1.small",
	Name:              "k8s",
	NodeCount:         &nodeCount,
	MasterLBEnabled:   &masterLBEnabled,
}

cluster, err := clusters.Create(context.TODO(), serviceClient, createOpts).Extract()
if err != nil {
	panic(err)
}

Example to Get a Cluster 

clusterName := "cluster123"
cluster, err := clusters.Get(context.TODO(), serviceClient, clusterName).Extract()
if err != nil {
	panic(err)
}
fmt.Printf("%+v\n", cluster)

Example to List Clusters 

listOpts := clusters.ListOpts{
	Limit: 20,
}

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

allClusters, err := clusters.ExtractClusters(allPages)
if err != nil {
	panic(err)
}

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

Example to List Clusters with detailed information 

allPagesDetail, err := clusters.ListDetail(serviceClient, clusters.ListOpts{}).AllPages(context.TODO())
if err != nil {
    panic(err)
}

allClustersDetail, err := clusters.ExtractClusters(allPagesDetail)
if err != nil {
    panic(err)
}

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

Example to Update a Cluster 

updateOpts := []clusters.UpdateOptsBuilder{
	clusters.UpdateOpts{
		Op:    clusters.ReplaceOp,
		Path:  "/master_lb_enabled",
		Value: "True",
	},
	clusters.UpdateOpts{
		Op:    clusters.ReplaceOp,
		Path:  "/registry_enabled",
		Value: "True",
	},
}
clusterUUID, err := clusters.Update(context.TODO(), serviceClient, clusterUUID, updateOpts).Extract()
if err != nil {
	panic(err)
}
fmt.Printf("%s\n", clusterUUID)

Example to Upgrade a Cluster 

upgradeOpts := clusters.UpgradeOpts{
	ClusterTemplate: "0562d357-8641-4759-8fed-8173f02c9633",
}
clusterUUID, err := clusters.Upgrade(context.TODO(), serviceClient, clusterUUID, upgradeOpts).Extract()
if err != nil {
	panic(err)
}
fmt.Printf("%s\n", clusterUUID)

Example to Delete a Cluster 

clusterUUID := "dc6d336e3fc4c0a951b5698cd1236ee"
err := clusters.Delete(context.TODO(), serviceClient, clusterUUID).ExtractErr()
if err != nil {
	panic(err)
}

Functions

func List 

func List(c *gophercloud.ServiceClient, opts ListOptsBuilder) pagination.Pager

List returns a Pager which allows you to iterate over a collection of clusters. It accepts a ListOptsBuilder, which allows you to sort the returned collection for greater efficiency.

func ListDetail 

func ListDetail(c *gophercloud.ServiceClient, opts ListOptsBuilder) pagination.Pager

ListDetail returns a Pager which allows you to iterate over a collection of clusters with detailed information. It accepts a ListOptsBuilder, which allows you to sort the returned collection for greater efficiency.
