Types ¶
type Renewer ¶
type Renewer struct {
// contains filtered or unexported fields
}
Renewer is a process for renewing a secret.
renewer, err := client.NewRenewer(&RenewerInput{
Secret: mySecret,
})
go renewer.Renew()
defer renewer.Stop()
for {
select {
case err := <-renewer.DoneCh():
if err != nil {
log.Fatal(err)
}
// Renewal is now over
case renewal := <-renewer.RenewCh():
log.Printf("Successfully renewed: %#v", renewal)
}
}
The `DoneCh` will return if renewal fails or if the remaining lease duration after a renewal is less than or equal to the grace (in number of seconds). In both cases, the caller should attempt a re-read of the secret or reauthenticate to get a new token. Clients should check the return value of the channel to see if renewal was successful.
func NewRenewer ¶
func NewRenewer(c *api.Client, i *RenewerInput) (*Renewer, error)
NewRenewer creates a new Renewer from the given input.
func (*Renewer) DoneCh ¶
DoneCh returns the channel where the Renewer will publish when renewal stops. If there is an error, this will be an error.
func (*Renewer) Renew ¶
func (r *Renewer) Renew()
Renew starts a background process for renewing this secret. When the secret has auth data, this attempts to renew the auth (token). When the secret has a lease, this attempts to renew the lease.
type RenewerInput ¶
type RenewerInput struct {
// Secret is the secret to renew
Secret *api.Secret
// DEPRECATED: this does not do anything.
Grace time.Duration
// Rand is the randomizer to use for underlying randomization. If not
// provided, one will be generated and seeded automatically. If provided, it
// is assumed to have already been seeded.
Rand *rand.Rand
// RenewBuffer is the size of the buffered channel where renew messages are
// dispatched.
RenewBuffer int
// The new TTL, in seconds, that should be set on the lease. The TTL set
// here may or may not be honored by the vault server, based on Vault
// configuration or any associated max TTL values.
Increment int
}
RenewerInput is used as input to the renew function.
