Types

type AWSSecret

type AWSSecret string

AWSSecret is a wrapper preventing accidental printing or marshalling

func (AWSSecret) GoString

func (s AWSSecret) GoString() string

The GoString method is used to print values passed as an operand to a %#v format.

func (AWSSecret) MarshalJSON

func (s AWSSecret) MarshalJSON() ([]byte, error)

MarshalJSON Marshaler is the interface implemented by types that can marshal themselves into valid JSON.

func (AWSSecret) MarshalText

func (s AWSSecret) MarshalText() ([]byte, error)

MarshalText encodes the receiver into UTF-8-encoded text and returns the result.

func (AWSSecret) String

func (s AWSSecret) String() string

The String method is used to print values passed as an operand to any format that accepts a string or to an unformatted printer such as Print.

func (AWSSecret) Value

func (s AWSSecret) Value() string

Value is used to return masked secret value

type AWSSecretsManager

type AWSSecretsManager struct {
	Client         *secretsmanager.Client
	RequestTimeout time.Duration
	// contains filtered or unexported fields
}

AWSSecretsManager is an AWS Secrets Manager service wrapper

func NewAWSSecretsManager

func NewAWSSecretsManager(requestTimeout time.Duration) (*AWSSecretsManager, error)

NewAWSSecretsManager create a new connection to AWS Secrets Manager

func (*AWSSecretsManager) CreateSecret

func (sm *AWSSecretsManager) CreateSecret(key string, val string, override bool) error

CreateSecret creates a specific secret by key

func (*AWSSecretsManager) GetSecret

func (sm *AWSSecretsManager) GetSecret(key string) (AWSSecret, error)

GetSecret gets a specific secret by key

func (*AWSSecretsManager) RemoveSecret

func (sm *AWSSecretsManager) RemoveSecret(key string, noRecovery bool) error

RemoveSecret removes a specific secret by key

type Config

type Config struct {
	LokiURL               string
