By the way, I got it working. Here's a minimal working example of
hpcguix-web (meant to be run in a Docker container):
--8<---------------cut here---------------start------------->8---
(use-modules
(guix channels) ;; channel (for hpcguix-web)
(gnu packages certs) ;; nss-certs
(gnu services networking) ;; dhcp-client-service-type
(gnu services ssh) ;; openssh-service-type
(gnu services web) ;; hpcguix-web-service-type
(gnu system image)
(gnu))
(operating-system
;; this will be ignored
(bootloader
(bootloader-configuration
(bootloader grub-bootloader)
(targets '())
(terminal-outputs '())))
;; this will be ignored
(file-systems '())
(firmware '())
(host-name "host-name")
;; hpcguix-web requires pulling channels via git which requires nss-cers
(packages (cons nss-certs %base-packages))
(services
(cons*
(service hpcguix-web-service-type
(hpcguix-web-configuration
(specs
#~(begin
(use-modules (guix channels))
(define site-config
(hpcweb-configuration
(channels
(cons*
;; TODO: add channels here
%default-guix-channel))))))))
(service dhcp-client-service-type)
%base-services))
;; TODO: set timezone
(timezone "Etc/UTC")
(users
(list
;; un-comment this user when you want to debug this os-declaration:
;; (user-account
;; (name "debug")
;; (password "debug")
;; (group "users")
;; (supplementary-groups
;; (list "wheel" "netdev" "audio" "video")))
)))
--8<---------------cut here---------------end--------------->8---
