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(serviceClient, createOpts).Extract() if err != nil { panic(err) }
Example to Get a Cluster
clusterName := "cluster123" cluster, err := clusters.Get(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() 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() 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(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(serviceClient, clusterUUID, upgradeOpts).Extract() if err != nil { panic(err) } fmt.Printf("%s\n", clusterUUID)
Example to Delete a Cluster
clusterUUID := "dc6d336e3fc4c0a951b5698cd1236ee" err := clusters.Delete(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.
