Should you wish to manage your Docker containers with the same consistent interface you use for your other Shepherd services, oci-container-service-type is the tool to use: given an Open Container Initiative (OCI) container image, it will run it in a Shepherd service. One example where this is useful: it lets you run services that are available as Docker/OCI images but not yet packaged for Guix.
This is a thin wrapper around Docker’s CLI that executes OCI images backed processes as Shepherd Services.
(service oci-container-service-type
(list
(oci-container-configuration
(network "host")
(image
(oci-image
(repository "guile")
(tag "3")
(value (specifications->manifest '("guile")))
(pack-options '(#:symlinks (("/bin/guile" -> "bin/guile"))
#:max-layers 2))))
(entrypoint "/bin/guile")
(command
'("-c" "(display \"hello!\n\")")))
(oci-container-configuration
(image "prom/prometheus")
(ports
'(("9000" . "9000")
("9090" . "9090"))))
(oci-container-configuration
(image "grafana/grafana:10.0.1")
(network "host")
(volumes
'("/var/lib/grafana:/var/lib/grafana")))))
In this example three different Shepherd services are going to be added to
the system. Each oci-container-configuration record translates to a
docker run invocation and its fields directly map to options. You
can refer to the
upstream
documentation for the semantics of each value. If the images are not found,
they will be
pulled.
The services with (network "host") are going to be attached to the
host network and are supposed to behave like native processes with regard to
networking.
Available oci-container-configuration fields are:
user (default: "oci-container") (type: string)The user under whose authority docker commands will be run.
group (default: "docker") (type: string)The group under whose authority docker commands will be run.
command (default: '()) (type: list-of-strings)Overwrite the default command (CMD) of the image.
entrypoint (default: "") (type: string)Overwrite the default entrypoint (ENTRYPOINT) of the image.
host-environment (default: '()) (type: list)Set environment variables in the host environment where docker run
is invoked. This is especially useful to pass secrets from the host to the
container without having them on the docker run’s command line: by
setting the MYSQL_PASSWORD on the host and by passing --env
MYSQL_PASSWORD through the extra-arguments field, it is possible to
securely set values in the container environment. This field’s value can be
a list of pairs or strings, even mixed:
(list '("LANGUAGE\" . "eo:ca:eu")
"JAVA_HOME=/opt/java")
Pair members can be strings, gexps or file-like objects. Strings are passed
directly to make-forkexec-constructor.
environment (default: '()) (type: list)Set environment variables. This can be a list of pairs or strings, even mixed:
(list '("LANGUAGE" . "eo:ca:eu")
"JAVA_HOME=/opt/java")
Pair members can be strings, gexps or file-like objects. Strings are passed directly to the Docker CLI. You can refer to the upstream documentation for semantics.
image (type: string-or-oci-image)The image used to build the container. It can be a string or an
oci-image record. Strings are resolved by the Docker Engine, and
follow the usual format myregistry.local:5000/testing/test-image:tag.
provision (default: "") (type: string)Set the name of the provisioned Shepherd service.
requirement (default: '()) (type: list-of-symbols)Set additional Shepherd services dependencies to the provisioned Shepherd service.
log-file (type: maybe-string)When log-file is set, it names the file to which the service’s
standard output and standard error are redirected. log-file is
created if it does not exist, otherwise it is appended to.
auto-start? (default: #t) (type: boolean)Whether this service should be started automatically by the Shepherd. If it
is #f, the service has to be started manually with herd
start.
respawn? (default: #f) (type: boolean)Whether to have Shepherd restart the service when it stops, for instance when the underlying process dies.
shepherd-actions (default: '()) (type: list-of-symbols)This is a list of shepherd-action records defining actions supported
by the service.
network (default: "") (type: string)Set a Docker network for the spawned container.
ports (default: '()) (type: list)Set the port or port ranges to expose from the spawned container. This can be a list of pairs or strings, even mixed:
(list '("8080" . "80")
"10443:443")
Pair members can be strings, gexps or file-like objects. Strings are passed directly to the Docker CLI. You can refer to the upstream documentation for semantics.
volumes (default: '()) (type: list)Set volume mappings for the spawned container. This can be a list of pairs or strings, even mixed:
(list '("/root/data/grafana" . "/var/lib/grafana")
"/gnu/store:/gnu/store")
Pair members can be strings, gexps or file-like objects. Strings are passed directly to the Docker CLI. You can refer to the upstream documentation for semantics.
container-user (default: "") (type: string)Set the current user inside the spawned container. You can refer to the upstream documentation for semantics.
workdir (default: "") (type: string)Set the current working directory for the spawned Shepherd service. You can refer to the upstream documentation for semantics.

to the docker run invocation.
Available oci-image fields are:
repository (type: string)A string like myregistry.local:5000/testing/test-image that names the
OCI image.
tag (default: "latest") (type: string)A string representing the OCI image tag. Defaults to latest.
value (type: oci-lowerable-image)A manifest or operating-system record that will be lowered
into an OCI compatible tarball. Otherwise this field’s value can be a gexp
or a file-like object that evaluates to an OCI compatible tarball.
pack-options (default: '()) (type: list)An optional set of keyword arguments that will be passed to the
docker-image procedure from guix scripts pack. They can be
used to replicate guix pack behavior:
(oci-image
(repository "guile")
(tag "3")
(value
(specifications->manifest '("guile")))
(pack-options '(#:symlinks (("/bin/guile" -> "bin/guile"))
#:max-layers 2)))
If the value field is an operating-system record, this field’s
value will be ignored.
system (default: "") (type: string)Attempt to build for a given system, e.g. "i686-linux"
target (default: "") (type: string)Attempt to cross-build for a given triple, e.g. "aarch64-linux-gnu"

fail2ban scans log files
(e.g. /var/log/apache/error_log) and bans IP addresses that show
malicious signs – repeated password failures, attempts to make use of
exploits, etc.
fail2ban-service-type service type is provided by the (gnu
services security) module.
This service type runs the fail2ban daemon. It can be configured in
various ways, which are:
The basic parameters of the Fail2Ban service can be configured via its
fail2ban configuration, which is documented below.
The fail2ban-jail-service function can be used to add new Fail2Ban
jails.
Service developers can extend the fail2ban-service-type service type
itself via the usual service extension mechanism.
This is the type of the service that runs fail2ban daemon. Below is
an example of a basic, explicit configuration:
(append
(list
(service fail2ban-service-type
(fail2ban-configuration
(extra-jails
(list
(fail2ban-jail-configuration
(name "sshd")
(enabled? #t))))))
;; There is no implicit dependency on an actual SSH
;; service, so you need to provide one.
(service openssh-service-type))
%base-services)
Extend svc-type, a <service-type> object with jail, a
fail2ban-jail-configuration object.
Por ejemplo:
(append
(list
(service
;; The 'fail2ban-jail-service' procedure can extend any service type
;; with a fail2ban jail. This removes the requirement to explicitly
;; extend services with fail2ban-service-type.
(fail2ban-jail-service
openssh-service-type
(fail2ban-jail-configuration
(name "sshd")
(enabled? #t)))
(openssh-configuration ...))))
Below is the reference for the different jail-service-type
configuration records.
Available fail2ban-configuration fields are:

max-matches (type: maybe-integer)The number of matches stored in ticket (resolvable via tag <matches>)
in action.
find-time (type: maybe-string)The time window during which the maximum retry count must be reached for an
IP address to be banned. A host is banned if it has generated
max-retry during the last find-time seconds (e.g.
(find-time "10m")). It can be provided in seconds or using
Fail2Ban’s "time abbreviation format", as described in man 5
jail.conf.
ban-time (type: maybe-string)The duration, in seconds or time abbreviated format, that a ban should
last. (e.g. (ban-time "10m")).
ban-time-increment? (type: maybe-boolean)Whether to consider past bans to compute increases to the default ban time of a specific IP address.
ban-time-factor (type: maybe-string)The coefficient to use to compute an exponentially growing ban time.
ban-time-formula (type: maybe-string)This is the formula used to calculate the next value of a ban time.

The (gnu services backup) module offers services for backing up file
system trees. For now, it provides the restic-backup-service-type.
With restic-backup-service-type, you can periodically back up
directories and files with Restic, which
supports end-to-end encryption and deduplication. Consider the following
configuration:
(use-service-modules backup …) ;for 'restic-backup-service-type' (use-package-modules sync …) ;for 'rclone' (operating-system ;; … (packages (append (list rclone) ;for use by restic %base-packages)) (services (list (service restic-backup-service-type (restic-backup-configuration (jobs (list (restic-backup-job (name "remote-ftp") (repository "rclone:remote-ftp:backup/restic") (password-file "/root/.restic") ;; Every day at 23. (schedule "0 23 * * *") (files '("/root/.restic" "/root/.config/rclone" "/etc/ssh/ssh_host_rsa_key" "/etc/ssh/ssh_host_rsa_key.pub" "/etc/guix/signing-key.pub" "/etc/guix/signing-key.sec"))))))))))
Each restic-backup-job translates to an mcron job which sets the
RESTIC_PASSWORD environment variable by reading the first line of
password-file and runs restic backup, creating backups
using rclone of all the files listed in the files field.
The restic-backup-service-type installs as well restic-guix to
the system profile, a restic utility wrapper that allows for easier
interaction with the Guix configured backup jobs. For example the following
could be used to instantaneusly trigger a backup for the above shown
configuration, without waiting for the scheduled job:
restic-guix backup remote-ftp
Available restic-backup-configuration fields are:
jobs (default: '()) (type: list-of-restic-backup-jobs)The list of backup jobs for the current system.
Available restic-backup-job fields are:
restic (default: restic) (type: package)The restic package to be used for the current job.
user (default: "root") (type: string)The user used for running the current job.
repository (type: string)The restic repository target of this job.
name (type: string)A string denoting a name for this job.
password-file (type: string)Name of the password file, readable by the configured user, that will
be used to set the RESTIC_PASSWORD environment variable for the
current job.
schedule (type: gexp-or-string)A string or a gexp that will be passed as time specification in the mcron job specification (see mcron job specifications in GNU mcron).
files (default: '()) (type: list-of-lowerables)The list of files or directories to be backed up. It must be a list of values that can be lowered to strings.
verbose? (default: #f) (type: boolean)Whether to enable verbose output for the current backup job.
extra-flags (default: '()) (type: list-of-lowerables)A list of values that are lowered to strings. These will be passed as
command-line arguments to the current job restic backup
invokation.
The (gnu services upnp) module offers services related to
UPnP (Universal Plug and Play) and DLNA (Digital Living
Network Alliance), networking protocols that can be used for media streaming
and device interoperability within a local network. For now, this module
provides the readymedia-service-type.
ReadyMedia (formerly
known as MiniDLNA) is a DLNA/UPnP-AV media server. The project’s daemon,
minidlnad, can serve media files (audio, pictures, and video) to
DLNA/UPnP-AV clients available on the network.
readymedia-service-type is a Guix service that wraps around
ReadyMedia’s minidlnad.
Consider the following configuration:
(use-service-modules upnp …) (operating-system … (services (list (service readymedia-service-type (readymedia-configuration (media-directories (list (readymedia-media-directory (path "/media/audio") (types '(A))) (readymedia-media-directory (path "/media/video") (types '(V))) (readymedia-media-directory (path "/media/misc")))) (extra-config '(("notify_interval" . "60"))))) …)))
This sets up the ReadyMedia daemon to serve files from the media folders
