Overview

Package openstack contains resources for the individual OpenStack projects supported in Gophercloud. It also includes functions to authenticate to an OpenStack cloud and for provisioning various service-level clients.

Example of Creating a Service Client 

ao, err := openstack.AuthOptionsFromEnv()
provider, err := openstack.AuthenticatedClient(ao)
client, err := openstack.NewNetworkV2(client, gophercloud.EndpointOpts{
	Region: os.Getenv("OS_REGION_NAME"),
})

Functions

func AuthOptionsFromEnv 

func AuthOptionsFromEnv() (gophercloud.AuthOptions, error)

AuthOptionsFromEnv fills out an identity.AuthOptions structure with the settings found on the various OpenStack OS_* environment variables.

The following variables provide sources of truth: OS_AUTH_URL, OS_USERNAME, OS_PASSWORD, OS_TENANT_ID, and OS_TENANT_NAME.

Of these, OS_USERNAME, OS_PASSWORD, and OS_AUTH_URL must have settings, or an error will result. OS_TENANT_ID, OS_TENANT_NAME, OS_PROJECT_ID, and OS_PROJECT_NAME are optional.

OS_TENANT_ID and OS_TENANT_NAME are mutually exclusive to OS_PROJECT_ID and OS_PROJECT_NAME. If OS_PROJECT_ID and OS_PROJECT_NAME are set, they will still be referred as "tenant" in Gophercloud.

To use this function, first set the OS_* environment variables (for example, by sourcing an `openrc` file), then: 

opts, err := openstack.AuthOptionsFromEnv()
provider, err := openstack.AuthenticatedClient(opts)

func Authenticate 

func Authenticate(client *gophercloud.ProviderClient, options gophercloud.AuthOptions) error

Authenticate or re-authenticate against the most recent identity service supported at the provided endpoint.

func AuthenticateV2 

func AuthenticateV2(client *gophercloud.ProviderClient, options gophercloud.AuthOptions, eo gophercloud.EndpointOpts) error

AuthenticateV2 explicitly authenticates against the identity v2 endpoint.

func AuthenticateV3 

func AuthenticateV3(client *gophercloud.ProviderClient, options tokens3.AuthOptionsBuilder, eo gophercloud.EndpointOpts) error

AuthenticateV3 explicitly authenticates against the identity v3 service.

func AuthenticatedClient 

func AuthenticatedClient(options gophercloud.AuthOptions) (*gophercloud.ProviderClient, error)

AuthenticatedClient logs in to an OpenStack cloud found at the identity endpoint specified by the options, acquires a token, and returns a Provider Client instance that's ready to operate.

If the full path to a versioned identity endpoint was specified (example: http://example.com:5000/v3), that path will be used as the endpoint to query.

If a versionless endpoint was specified (example: http://example.com:5000/), the endpoint will be queried to determine which versions of the identity service are available, then chooses the most recent or most supported version.

Example: 

ao, err := openstack.AuthOptionsFromEnv()
provider, err := openstack.AuthenticatedClient(ao)
client, err := openstack.NewNetworkV2(client, gophercloud.EndpointOpts{
	Region: os.Getenv("OS_REGION_NAME"),
})

func NewBlockStorageV1 

func NewBlockStorageV1(client *gophercloud.ProviderClient, eo gophercloud.EndpointOpts) (*gophercloud.ServiceClient, error)

NewBlockStorageV1 creates a ServiceClient that may be used to access the v1 block storage service.

func NewBlockStorageV2 

func NewBlockStorageV2(client *gophercloud.ProviderClient, eo gophercloud.EndpointOpts) (*gophercloud.ServiceClient, error)

NewBlockStorageV2 creates a ServiceClient that may be used to access the v2 block storage service.

func NewBlockStorageV3 

func NewBlockStorageV3(client *gophercloud.ProviderClient, eo gophercloud.EndpointOpts) (*gophercloud.ServiceClient, error)

NewBlockStorageV3 creates a ServiceClient that may be used to access the v3 block storage service.

func NewCDNV1 

func NewCDNV1(client *gophercloud.ProviderClient, eo gophercloud.EndpointOpts) (*gophercloud.ServiceClient, error)

NewCDNV1 creates a ServiceClient that may be used to access the OpenStack v1 CDN service.

func NewClient 

func NewClient(endpoint string) (*gophercloud.ProviderClient, error)

NewClient prepares an unauthenticated ProviderClient instance. Most users will probably prefer using the AuthenticatedClient function instead.

This is useful if you wish to explicitly control the version of the identity service that's used for authentication explicitly, for example.

A basic example of using this would be: 

ao, err := openstack.AuthOptionsFromEnv()
provider, err := openstack.NewClient(ao.IdentityEndpoint)
client, err := openstack.NewIdentityV3(provider, gophercloud.EndpointOpts{})
