State (string alias)

(Appears on: ACMEAuthorization, ChallengeStatus, OrderStatus)

State represents the state of an ACME resource, such as an Order. The possible options here map to the corresponding values in the ACME specification. Full details of these values can be found here: https://tools.ietf.org/html/draft-ietf-acme-acme-15#section-7.1.6 Clients utilising this type must also gracefully handle unknown values, as the contents of this enumeration may be added to over time.

Value Description

"errored"

Errored signifies that the ACME resource has errored for some reason. This is a catch-all state, and is used for marking internal cert-manager errors such as validation failures. This is a final state.

"expired"

Expired signifies that an ACME resource has expired. If an Order is marked ‘Expired’, one of its validations may have expired or the Order itself. This is a final state.

"invalid"

Invalid signifies that an ACME resource is invalid for some reason. If an Order is marked ‘invalid’, one of its validations be have invalid for some reason. This is a final state.

"pending"

Pending signifies that an ACME resource is still pending and is not yet ready. If an Order is marked ‘Pending’, the validations for that Order are still in progress. This is a transient state.

"processing"

Processing signifies that an ACME resource is being processed by the server. If an Order is marked ‘Processing’, the validations for that Order are currently being processed. This is a transient state.

"ready"

Ready signifies that an ACME resource is in a ready state. If an order is ‘ready’, all of its challenges have been completed successfully and the order is ready to be finalized. Once finalized, it will transition to the Valid state. This is a transient state.

""

Unknown is not a real state as part of the ACME spec. It is used to represent an unrecognised value.

"valid"

Valid signifies that an ACME resource is in a valid state. If an order is ‘valid’, it has been finalized with the ACME server and the certificate can be retrieved from the ACME server using the certificate URL stored in the Order’s status subresource. This is a final state.
