# The certificate for the ACME service is exported as:
|
|
#
|
|
# config.test-support.acme.caCert
|
|
#
|
|
# This value can be used inside the configuration of other test nodes to inject
|
|
# the test certificate into security.pki.certificateFiles or into package
|
|
# overlays.
|
|
#
|
|
# Another value that's needed if you don't use a custom resolver (see below for
|
|
# notes on that) is to add the acme node as a nameserver to every node
|
|
# that needs to acquire certificates using ACME, because otherwise the API host
|
|
# for acme.test can't be resolved.
|
|
#
|
|
# A configuration example of a full node setup using this would be this:
|
|
#
|
|
# {
|
|
# acme = import ./common/acme/server;
|
|
#
|
|
# example = { nodes, ... }: {
|
|
# networking.nameservers = [
|
|
# nodes.acme.config.networking.primaryIPAddress
|
|
# ];
|
|
# security.pki.certificateFiles = [
|
|
# nodes.acme.config.test-support.acme.caCert
|
|
# ];
|
|
# };
|
|
# }
|
|
#
|
|
# By default, this module runs a local resolver, generated using resolver.nix
|
|
# from the parent directory to automatically discover all zones in the network.
|
|
#
|
|
# If you do not want this and want to use your own resolver, you can just
|
|
# override networking.nameservers like this:
|
|
#
|
|
# {
|
|
# acme = { nodes, lib, ... }: {
|
|
# imports = [ ./common/acme/server ];
|
|
# networking.nameservers = lib.mkForce [
|
|
# nodes.myresolver.config.networking.primaryIPAddress
|
|
# ];
|
|
# };
|
|
#
|
|
# myresolver = ...;
|
|
# }
|
|
#
|
|
# Keep in mind, that currently only _one_ resolver is supported, if you have
|
|
# more than one resolver in networking.nameservers only the first one will be
|
|
# used.
|
|
#
|
|
# Also make sure that whenever you use a resolver from a different test node
|
|
# that it has to be started _before_ the ACME service.
