Overview

Package instances provides information and interaction with the instance API resource in the OpenStack Database service.

A database instance is an isolated database environment with compute and storage resources in a single tenant environment on a shared physical host machine.

Functions

func List 

func List(client *gophercloud.ServiceClient) pagination.Pager

List retrieves the status and information for all database instances.

Types

type ActionResult 

type ActionResult struct {
	gophercloud.ErrResult
}

ActionResult represents the result of action requests, such as: restarting an instance service, resizing its memory allocation, and resizing its attached volume size.

func Resize 

func Resize(client *gophercloud.ServiceClient, id, flavorRef string) (r ActionResult)

Resize changes the memory size of the instance, assuming a valid flavorRef is provided. It will also restart the MySQL service.

func ResizeVolume 

func ResizeVolume(client *gophercloud.ServiceClient, id string, size int) (r ActionResult)

ResizeVolume will resize the attached volume for an instance. It supports only increasing the volume size and does not support decreasing the size. The volume size is in gigabytes (GB) and must be an integer.

func Restart 

func Restart(client *gophercloud.ServiceClient, id string) (r ActionResult)

Restart will restart only the MySQL Instance. Restarting MySQL will erase any dynamic configuration settings that you have made within MySQL. The MySQL service will be unavailable until the instance restarts.

type Address 

type Address struct {
	// The address type, e.g public
	Type string

	// The actual IP address
	Address string
}

Address represents the IP address and its type to connect with the instance.

type ConfigurationResult 

type ConfigurationResult struct {
	gophercloud.ErrResult
}

ConfigurationResult represents the result of a AttachConfigurationGroup/DetachConfigurationGroup operation.

func AttachConfigurationGroup 

func AttachConfigurationGroup(client *gophercloud.ServiceClient, instanceID string, configID string) (r ConfigurationResult)

func DetachConfigurationGroup 

func DetachConfigurationGroup(client *gophercloud.ServiceClient, instanceID string) (r ConfigurationResult)

DetachConfigurationGroup will dettach configuration group from the instance

type CreateOpts 

type CreateOpts struct {
	// Either the integer UUID (in string form) of the flavor, or its URI
	// reference as specified in the response from the List() call. Required.
	FlavorRef string
	// Specifies the volume size in gigabytes (GB). The value must be between 1
	// and 300. Required.
	Size int
	// Name of the instance to create. The length of the name is limited to
	// 255 characters and any characters are permitted. Optional.
	Name string
	// A slice of database information options.
	Databases db.CreateOptsBuilder
	// A slice of user information options.
	Users users.CreateOptsBuilder
	// Options to configure the type of datastore the instance will use. This is
	// optional, and if excluded will default to MySQL.

	// contains filtered or unexported fields
}

CreateResult represents the result of a Create operation.

func Create 

func Create(client *gophercloud.ServiceClient, opts CreateOptsBuilder) (r CreateResult)

Create asynchronously provisions a new database instance. It requires the user to specify a flavor and a volume size. The API service then provisions the instance with the requested flavor and sets up a volume of the specified size, which is the storage for the database instance.

Although this call only allows the creation of 1 instance per request, you can create an instance with multiple databases and users. The default binding for a MySQL instance is port 3306.

func (CreateResult) Extract 

func (r CreateResult) Extract() (*Instance, error)

Extract will extract an Instance from various result structs.

type DatastoreOpts 

type DatastoreOpts struct {

}

DatastoreOpts represents the configuration for how an instance stores data.

func (DatastoreOpts) ToMap 

func (opts DatastoreOpts) ToMap() (map[string]interface{}, error)

ToMap converts a DatastoreOpts to a map[string]string (for a request body)

type DeleteResult 

type DeleteResult struct {
	gophercloud.ErrResult
}

DeleteResult represents the result of a Delete operation.

func Delete 

func Delete(client *gophercloud.ServiceClient, id string) (r DeleteResult)

Delete permanently destroys the database instance.

type EnableRootUserResult

func EnableRootUser 

func EnableRootUser(client *gophercloud.ServiceClient, id string) (r EnableRootUserResult)

EnableRootUser enables the login from any host for the root user and provides the user with a generated root password.

func (EnableRootUserResult) Extract 

func (r EnableRootUserResult) Extract() (*users.User, error)

Extract will extract root user information from a UserRootResult.

type Fault 

type Fault struct {
	// Indicates the time when the fault occured
	Created time.Time `json:"-"`

	// A message describing the fault reason
	Message string

	// More details about the fault, for example a stack trace. Only filled
	// in for admin users.
	Details string
}

Fault describes the fault reason in more detail when a database instance has errored

	// A DNS-resolvable hostname associated with the database instance (rather
	// than an IPv4 address). Since the hostname always resolves to the correct
	// IP address of the database instance, this relieves the user from the task
	// of maintaining the mapping. Note that although the IP address may likely
	// change on resizing, migrating, and so forth, the hostname always resolves
	// to the correct database instance.
	Hostname string

	// The IP addresses associated with the database instance
	// Is empty if the instance has a hostname.
	// Deprecated in favor of Addresses.
