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

Types

type Cloud

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

Cloud provides Azure metadata and API access.

func New

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

New initializes Cloud with the needed API clients. Default credentials are used for authentication.

func (*Cloud) GetCCMConfig

func (c *Cloud) GetCCMConfig(ctx context.Context, providerID string, cloudServiceAccountURI string) ([]byte, error)

GetCCMConfig returns the configuration needed for the Kubernetes Cloud Controller Manager on Azure.

func (*Cloud) GetLoadBalancerEndpoint

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

GetLoadBalancerEndpoint retrieves the first load balancer IP from cloud provider metadata.

The returned string is an IP address without a port, but the method name needs to satisfy the metadata interface.

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.

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.

type IMDSClient

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

IMDSClient is a client for the Azure Instance Metadata Service.

func NewIMDSClient

func NewIMDSClient() *IMDSClient

NewIMDSClient creates a new IMDSClient.

func (*IMDSClient) Tags

func (c *IMDSClient) Tags(ctx context.Context) (map[string]string, error)

Tags returns the tags of the instance the function is called from.

type Logger

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

Logger implements CloudLogger interface for Azure to Disclose early boot logs into Azure's App Insights service.

func NewLogger

func NewLogger(ctx context.Context) (*Logger, error)

NewLogger creates a new client to store information in Azure Application Insights https://github.com/Microsoft/ApplicationInsights-go

func (*Logger) Close

func (l *Logger) Close() error

Close blocks until all information are written to cloud API.

func (*Logger) Disclose

func (l *Logger) Disclose(msg string)

Disclose stores log information in Azure Application Insights! Do **NOT** log sensitive information!
