Overview ¶
Package servergroups provides the ability to manage server groups.
Example to List Server Groups
allpages, err := servergroups.List(computeClient).AllPages()
if err != nil {
panic(err)
}
allServerGroups, err := servergroups.ExtractServerGroups(allPages)
if err != nil {
panic(err)
}
for _, sg := range allServerGroups {
fmt.Printf("%#v\n", sg)
}
Example to Create a Server Group
createOpts := servergroups.CreateOpts{
Name: "my_sg",
Policies: []string{"anti-affinity"},
}
sg, err := servergroups.Create(computeClient, createOpts).Extract()
if err != nil {
panic(err)
}
Example to Delete a Server Group
sgID := "7a6f29ad-e34d-4368-951a-58a08f11cfb7"
err := servergroups.Delete(computeClient, sgID).ExtractErr()
if err != nil {
panic(err)
}

Functions ¶
func List ¶
func List(client *gophercloud.ServiceClient) pagination.Pager
List returns a Pager that allows you to iterate over a collection of ServerGroups.
Types ¶
type CreateOpts ¶
type CreateOpts struct {
// Name is the name of the server group
Name string `json:"name" required:"true"`
// Policies are the server group policies
Policies []string `json:"policies" required:"true"`
}
CreateOpts specifies Server Group creation parameters.
func (CreateOpts) ToServerGroupCreateMap ¶
func (opts CreateOpts) ToServerGroupCreateMap() (map[string]interface{}, error)
ToServerGroupCreateMap constructs a request body from CreateOpts.
type CreateOptsBuilder ¶
CreateOptsBuilder allows extensions to add additional parameters to the Create request.
type CreateResult ¶
type CreateResult struct {
ServerGroupResult
}
CreateResult is the response from a Create operation. Call its Extract method to interpret it as a ServerGroup.
func Create ¶
func Create(client *gophercloud.ServiceClient, opts CreateOptsBuilder) (r CreateResult)
Create requests the creation of a new Server Group.
type DeleteResult ¶
type DeleteResult struct {
gophercloud.ErrResult
}
DeleteResult is the response from a Delete operation. Call its ExtractErr method to determine if the call succeeded or failed.
func Delete ¶
func Delete(client *gophercloud.ServiceClient, id string) (r DeleteResult)
Delete requests the deletion of a previously allocated ServerGroup.
type GetResult ¶
type GetResult struct {
ServerGroupResult
}
GetResult is the response from a Get operation. Call its Extract method to interpret it as a ServerGroup.
type ServerGroup ¶
type ServerGroup struct {
// ID is the unique ID of the Server Group.
ID string `json:"id"`
// Name is the common name of the server group.
Name string `json:"name"`
// Polices are the group policies.
//
// Normally a single policy is applied:
//
// "affinity" will place all servers within the server group on the
// same compute node.
//
// "anti-affinity" will place servers within the server group on different
// compute nodes.
Policies []string `json:"policies"`
// Members are the members of the server group.
Members []string `json:"members"`
// Metadata includes a list of all user-specified key-value pairs attached
// to the Server Group.
Metadata map[string]interface{}
}
A ServerGroup creates a policy for instance placement in the cloud.
func ExtractServerGroups ¶
func ExtractServerGroups(r pagination.Page) ([]ServerGroup, error)
ExtractServerGroups interprets a page of results as a slice of ServerGroups.
type ServerGroupPage ¶
type ServerGroupPage struct {
pagination.SinglePageBase
}
ServerGroupPage stores a single page of all ServerGroups results from a List call.
func (ServerGroupPage) IsEmpty ¶
func (page ServerGroupPage) IsEmpty() (bool, error)
IsEmpty determines whether or not a ServerGroupsPage is empty.
type ServerGroupResult ¶
type ServerGroupResult struct {
gophercloud.Result
}
func (ServerGroupResult) Extract ¶
func (r ServerGroupResult) Extract() (*ServerGroup, error)
Extract is a method that attempts to interpret any Server Group resource response as a ServerGroup struct.
