Types

type InstanceInfo

type InstanceInfo struct {
	InstanceId string
	Region     string
}

InstanceInfo contains information about current EC2 instance

type SSMEC2RoleProvider

type SSMEC2RoleProvider struct {
	credentials.Expiry
	// ExpiryWindow will allow the credentials to trigger refreshing prior to
	// the credentials actually expiring. This is beneficial so race conditions
	// with expiring credentials do not cause request to fail unexpectedly
	// due to ExpiredTokenException exceptions.
	//
	// So a ExpiryWindow of 10s would cause calls to IsExpired() to return true
	// 10 seconds before the credentials are actually expired.
	//
	// If ExpiryWindow is 0 or less it will be ignored.
	ExpiryWindow time.Duration
	Config       *appconfig.SsmagentConfig
	Log          log.T
