AuthOptions stores information needed to authenticate to an OpenStack cluster.
|
|
You can populate one manually, or use a provider's AuthOptionsFromEnv() function
|
|
to read relevant information from the standard environment variables. Pass one
|
|
to a provider's AuthenticatedClient function to authenticate and obtain a
|
|
ProviderClient representing an active session on that provider.
|
|
|
|
Its fields are the union of those recognized by each identity implementation and
|
|
provider.
