Global validation settings

Starting from version 2.2.0, you can configure validation settings to apply for all host names across all managed renewals (within the scope of a single ACME service, so your --test endpoint will still have different settings than the regular one).


If you want to have a certificate with hosts from domains, with the DNS for each of them hosted at a different provider. It’s not possible to configure that using the regular renewal configuration process, but by setting global validation options for at least of the hosts, it becomes possible.

Another scenario is when you managed multiple renewals with complicated validation settings. While the secret manager already provides a good way to rotate secret credentials like API keys, in some cases it’s also convenient to be able to quickly update non-secret information like paths, user names, subscription identifiers etc. in multiple renewals. Or at least to not have to input all of that information every time.


You can find the validation options in the main menu under More options.... From the menu you can add, edit or remove settings. The settings consist of the regular settings that also apply to a single renewal, plus:

  • A pattern that determines wether or not the settings will apply to a specific host name. You may use a * for a range of any characters and a ? for any single character. For example: the pattern example.* will match and (but not and the pattern ? will match and (but not Note that multiple patterns can be combined by comma seperating them.
  • A number incidating priority. Settings with a lower value for the priority will be processed first, e.g. priority 1 will take preference over priority 2. This is only relevant when a hostname matches with multiple patterns.


The global validation settings are stored in a file called validation.json. Sensitive information is encrypted just like in regular .renewal.json files.
