Show: Minimal Working Example of hpcguix-web

[Mekeor Melire <mekeor@posteo.de>]

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---
