# Fully pluggable module to have Letsencrypt's Boulder ACME service running in # a test environment. # # The certificate for the ACME service is exported as: # # config.test-support.letsencrypt.caCert # # This value can be used inside the configuration of other test nodes to inject # the snakeoil 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 letsencrypt node as a nameserver to every node # that needs to acquire certificates using ACME, because otherwise the API host # for letsencrypt.org can't be resolved. # # A configuration example of a full node setup using this would be this: # # { # letsencrypt = import ./common/letsencrypt.nix; # # example = { nodes, ... }: { # networking.nameservers = [ # nodes.letsencrypt.config.networking.primaryIPAddress # ]; # security.pki.certificateFiles = [ # nodes.letsencrypt.config.test-support.letsencrypt.caCert # ]; # }; # } # # By default, this module runs a local resolver, generated using resolver.nix # from the same 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: # # { # letsencrypt = { nodes, ... }: { # imports = [ ./common/letsencrypt.nix ]; # networking.nameservers = [ # 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. { config, pkgs, lib, ... }: let softhsm = pkgs.stdenv.mkDerivation rec { name = "softhsm-${version}"; version = "1.3.8"; src = pkgs.fetchurl { url = "https://dist.opendnssec.org/source/${name}.tar.gz"; sha256 = "0flmnpkgp65ym7w3qyg78d3fbmvq3aznmi66rgd420n33shf7aif"; }; configureFlags = [ "--with-botan=${pkgs.botan}" ]; buildInputs = [ pkgs.sqlite ]; }; pkcs11-proxy = pkgs.stdenv.mkDerivation { name = "pkcs11-proxy"; src = pkgs.fetchFromGitHub { owner = "SUNET"; repo = "pkcs11-proxy"; rev = "944684f78bca0c8da6cabe3fa273fed3db44a890"; sha256 = "1nxgd29y9wmifm11pjcdpd2y293p0dgi0x5ycis55miy97n0f5zy"; }; postPatch = "patchShebangs mksyscalls.sh"; nativeBuildInputs = [ pkgs.cmake ]; buildInputs = [ pkgs.openssl pkgs.libseccomp ]; }; mkGoDep = { goPackagePath, url ?
