Implements interaction with the GCP API.

Instance metadata is retrieved from the GCP metadata API.

Retrieving metadata of other instances is done by using the GCP compute API, and requires GCP credentials.

Types

type Cloud

type Cloud struct {
	// contains filtered or unexported fields
}

Cloud provides GCP cloud metadata information and API access.

func New

func New(ctx context.Context) (cloud *Cloud, err error)

New creates and initializes Cloud. The Close method should be called when Cloud is no longer needed.

func (*Cloud) Close

func (c *Cloud) Close()

Close closes all connections to the GCP API server.

func (*Cloud) GetLoadBalancerEndpoint

func (c *Cloud) GetLoadBalancerEndpoint(ctx context.Context) (host, port string, err error)

GetLoadBalancerEndpoint returns the endpoint of the load balancer.

func (*Cloud) InitSecretHash

func (c *Cloud) InitSecretHash(ctx context.Context) ([]byte, error)

InitSecretHash retrieves the InitSecretHash of the current instance.

func (*Cloud) List

func (c *Cloud) List(ctx context.Context) ([]metadata.InstanceMetadata, error)

List retrieves all instances belonging to the current constellation. On GCP, this is done by listing all instances in a region by requesting all instances in each zone.

func (*Cloud) ProviderID

func (c *Cloud) ProviderID(_ context.Context) (string, error)

ProviderID returns the providerID of the current instance.

func (*Cloud) Self

func (c *Cloud) Self(ctx context.Context) (metadata.InstanceMetadata, error)

Self retrieves the current instance.

func (*Cloud) UID

func (c *Cloud) UID(ctx context.Context) (string, error)

UID retrieves the UID of the constellation.
