    renewBefore
    Kubernetes meta/v1.Duration
    (Optional)

    How long before the currently issued certificate’s expiry cert-manager should renew the certificate. For example, if a certificate is valid for 60 minutes, and renewBefore=10m, cert-manager will begin to attempt to renew the certificate 50 minutes after it was issued (i.e. when there are 10 minutes remaining until the certificate is no longer valid).

    NOTE: The actual lifetime of the issued certificate is used to determine the renewal time. If an issuer returns a certificate with a different lifetime than the one requested, cert-manager will use the lifetime of the issued certificate.

    If unset, this defaults to 13 of the issued certificate’s lifetime. Minimum accepted value is 5 minutes. Value must be in units accepted by Go time.ParseDuration https://golang.org/pkg/time/#ParseDuration. Cannot be set if the renewBeforePercentage field is set.

    renewBeforePercentage
    int32
    (Optional)

    renewBeforePercentage is like renewBefore, except it is a relative percentage rather than an absolute duration. For example, if a certificate is valid for 60 minutes, and renewBeforePercentage=25, cert-manager will begin to attempt to renew the certificate 45 minutes after it was issued (i.e. when there are 15 minutes (25%) remaining until the certificate is no longer valid).

    NOTE: The actual lifetime of the issued certificate is used to determine the renewal time. If an issuer returns a certificate with a different lifetime than the one requested, cert-manager will use the lifetime of the issued certificate.

    Value must be an integer in the range (0,100). The minimum effective renewBefore derived from the renewBeforePercentage and duration fields is 5 minutes. Cannot be set if the renewBefore field is set.

    revisionHistoryLimit
    int32
    (Optional)

    The maximum number of CertificateRequest revisions that are maintained in the Certificate’s history. Each revision represents a single CertificateRequest created by this Certificate, either when it was created, renewed, or Spec was changed.

      Resource Types:

        ConditionStatus (string alias)

        (Appears on: CertificateCondition, CertificateRequestCondition, IssuerCondition)

        ConditionStatus represents a condition’s status.

        A reference to a specific ‘key’ within a Secret resource. In some instances, key is a required field.

        FieldDescription
        LocalObjectReference
        LocalObjectReference
