oci-container-service-type: Wrong type argument in position 1 (expecting struct)

[Samuel Willey]

Hello, I am trying to utilize the oci-container-service-type to manage containers in Guix and running into issues. Below is the relevant portion of my config.scm:

(service oci-container-service-type
    (list
      (oci-container-configuration
        (image "pihole/pihole:latest")
        (provision "pihole")
        (network "host")
        (ports
          '("53:53/tcp"
            "53:53/udp"
            "67:67/udp"  ; Only required if using Pi-hole as DHCP server
            "80:80/tcp"))
        (environment
          '(("TZ" . "America/Chicago")))
          ; Uncomment and set a secure password, or it will be random
          ; '(("WEBPASSWORD" . "set a secure password here"))
        (volumes
          '("/docker/Pihole:/etc/pihole"
            "/docker/Dnsmasq:/etc/dnsmasq.d")))))

Below is the error I get when reconfiguring my system:

I also tried the example config given in the devel Guix manual, however that yielded the same results. Any help would be greatly appreciated.

I believe this is a bug[1] that was fixed in a recent commit
2b2337f275a6421a0d0964c54987df4ac74162e6.

If you "guix pull" then you should be able to reconfigure without an
issue.
