(chapter :title [Introduction]
:ident "chapter-introduction"
(p [guix-forge is a Guix service that lets you run a complete
,(ref :url "https://en.wikipedia.org/wiki/Forge_(software)"
:text "software forge") in the manner of GitHub, GitLab, etc. Unlike
other free software forges such as GitLab, Gitea, etc., guix-forge is
not a monolith but is an assemblage of several pieces of server
software wired up to function as one. In this sense, it is a
,(emph "meta-service"). guix-forge does for software forges what ,(ref
:url "https://mailinabox.email/" :text "Mail-in-a-Box") does for
email.])
(p [guix-forge integrates the following software components:]
(itemize
(item [,(ref :url "https://git.zx2c4.com/cgit/" :text "cgit")
and ,(ref :url "https://github.com/jonashaag/klaus/" :text "klaus")
(pick your favourite) to serve project git repositories on the web])
(item [,(ref :url "https://laminar.ohwg.net/" :text "laminar")
for continuous integration])
(item [,(ref :url "https://github.com/ndilieto/uacme/" :text
"uacme") and ,(ref :url "https://gnutls.org/" :text "gnutls") for
automatic provision and renewal of TLS certificates via ACME])))
(p [In the future, it will also provide:]
(itemize
(item [web server to serve static project sites])
(item [,(ref :url "https://public-inbox.org/README.html"
:text "public-inbox") for project discussions])))
(p [A choice of different software components may be offered
provided it does not complicate the interface too much.])
(p [guix-forge is provided on a best effort basis. Its
design is unstable, and open to change. We will try our best to not
break your system configuration often, but it might happen.])
(section :title [Philosophy]
(p [In order to empower ordinary users, software should not just
be free (as in freedom), but also be simple and easy to deploy,
especially for small-scale deployments. guix-forge is therefore
minimalistic, and does not require running large database servers such
as MariaDB and PostgreSQL.])
(p [While some state is inevitable, server software should
strive to be as stateless as an old analog television set. You switch
it on, and it works all the time. There are no pesky software updates,
and complex hidden state. guix-forge tries to be as stateless as
possible. Almost all of guix-forge's state can be version controlled,
and the rest are simple files that can be backed up easily.])
(p [,(ref
:url "https://drewdevault.com/2018/07/23/Git-is-already-distributed.html"
:text "Git is already federated and decentralized") with
email. guix-forge acknowledges this and prefers to support git's ,(ref
:url "https://drewdevault.com/2018/07/02/Email-driven-git.html"
:text "email driven workflow") with project discussion, bug reports
and patches all happening over email.])
(p [guix-forge is opinionated and will not expose all features
provided by the software components underlying it. Keeping
configuration options to a minimum is necessary to help casual users
deploy their own forge, and to reduce the likelihood of configuration
bugs.])))
(chapter :title [Tutorial]
:ident "chapter-tutorial"
(p [In this tutorial, you will learn how to set up guix-forge to
host continuous integration for a project. For the purposes of this
tutorial, we will set up continuous integration for the ,(ref :url
[https://github.com/aconchillo/guile-json] :text [guile-json])
project.])
(p [First, we clone the upstream guile-json repository into a
local bare clone at ,(file [/srv/git/guile-json]).])
(prog [$ git clone --bare https://github.com/aconchillo/guile-json /srv/git/guile-json
Cloning into bare repository '/srv/git/guile-json'...

Resolving deltas: 100% (742/742), done.]
:line #f)
(p [Now that we have a git repository to work with, we start
writing our Guix system configuration. We begin with a bunch of ,(code
[use-modules]) statements importing all required modules.])
(prog (source :language scheme
:file "doc/snippets/tutorial.scm"
:start 0 :stop 9)
:line #f)
(p [Then, we define the ,(ref :url
"https://guix.gnu.org/en/manual/devel/en/html_node/G_002dExpressions.html"
:text "G-expression") that will be run as a continuous integration job
on every commit. This G-expression uses ,(code [invoke]) from ,(code
[(guix build utils)]). Hence, we make it available to the G-expression
using ,(code [with-imported-modules]). In addition, it needs a number
of packages which we make available using ,(code [with-packages]). And
finally, within the body of the G-expression, we have commands cloning
the git repository, building the source and running the tests.])
(p [The attentive reader may notice what looks like ,(code [(guix
build utils)]) being referenced twice—once with ,(code
[with-imported-modules]) and again with ,(code [use-modules]). This is
not a mistake. G-expressions are serialized into Guile scripts. ,(code
[with-imported-modules]) ensures that code for ,(code [(guix build
utils)]) is available and is in the ,(ref :url
"https://www.gnu.org/software/guile/manual/html_node/Load-Paths.html"
:text "load path"). ,(code [use-modules]) actually imports ,(code
[(guix build utils)]) when the script runs. ,(code
[with-imported-modules]) is like installing a library in your system,
and ,(code [use-modules]) is like actually importing that library in a
script. Both are necessary.])
(prog (source :language scheme
:file "doc/snippets/tutorial.scm"
:start 11 :stop 22)
:line #f)
(p [Now, we configure a ,(code [<forge-project>]) record that
holds metadata about the project and wires up the G-expression we just
defined into a continuous integration job.])
(prog (source :language scheme
:file "doc/snippets/tutorial.scm"
:start 24 :stop 32)
:line #f)
(p [The ,(code [name]) and ,(code [description]) fields are
hopefully self-explanatory. The ,(code [user]) field specifies the
user who will own the git repository at the path specified by ,(code
[repository]). That user will therefore be able to push into the
repository through ssh or similar. git provides various ,(ref :url
"https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks" :text
"server-side hooks") that trigger on various events. Of these, the
,(file [post-receive]) hook triggers when pushed commits are
received. guix-forge sets up a ,(source-ref "guix/forge/forge.scm"
"\\(define\\* \\(ci-jobs-trigger-gexp" "post-receive hook script") in
the repository to trigger a continuous integration run on every
,(command [git push]).])
(p [And finally, we put everything together in an ,(code
[operating-system]) declaration. Notice the forge service configured
with ,(code [guile-json-project]) and the laminar service configured
with a port for the web interface to listen on.])
(prog (source :language scheme
:file "doc/snippets/tutorial.scm"
:start 34)
:line #f)
(p [Now that we have a complete ,(code [operating-system])
definition, let's use the following command to build a
container. After a lot of building, a container script should pop
out.])
(prog [$ guix system container --network --share=/srv/git/guile-json tutorial.scm
/gnu/store/ilg7c2hpkxhwircxpz22qhjsqp3i9har-run-container]
:line #f)
(p [The ,(code [--network]) flag specifies that the container
should share the network namespace of the host. To us, this means that
all ports opened by the container will be visible on the host without
any port forwarding or complicated configuration. The ,(code
[--share=/srv/git/guile-json]) option shares the git repository we
cloned earlier, with the container.])
(p [To start the container, simply run the container script as
root.])
(prog [# /gnu/store/ilg7c2hpkxhwircxpz22qhjsqp3i9har-run-container]
:line #f)
(p [Now, you can see the status of laminar and running jobs
through its web interface listening on ,(ref
:url "http://localhost:8080"). You can list and queue jobs on the
command-line like so:])
(prog [$ laminarc show-jobs
guile-json
$ laminarc queue guile-json
guile-json:1]
:line #f)
(p [That's it! You just set up your own continuous integration
system and took the first steps to owning your code!])
(p [You could easily use the same configuration to configure a
Guix system instead of a container. To do so, you will have to take
care of defining the bootloader, file systems and other settings as
per your needs. The overall configuration used in this tutorial is
repeated below for your reference.])
(prog (source :language scheme
:file "doc/snippets/tutorial.scm")))
(chapter :title [How To]
:ident "chapter-how-to"
(section :title [How to set up cgit]
:ident "section-how-to-set-up-cgit"
(p [guix-forge comes with an end-to-end cgit solution that not
only sets up cgit itself but also an nginx server complete with
automatically renewed TLS certificates. cgit even runs in its own
container for maximal security.])
(p [The cgit service uses the forge-nginx service as its web
server. The forge-nginx service in turn uses the ACME service to fetch
and renew TLS certificates. Here's a minimal working configuration.])
(prog (source :language scheme
:file "doc/snippets/how-to-set-up-cgit.scm")
:line #f)
(p [The cgit service configuration specifies the domain ,(samp
[git.example.org]) to serve cgit on and the ,(file "/srv/git")
repository directory containing bare git repositories to publish. The
forge nginx service configuration specifies the ports to serve HTTP
and HTTPS on. The ACME service configuration specifies the email
address to register an ACME account with. The sudoers file declaration
is required to allow the ,(samp [acme]) user to restart the nginx
server when a certificate is renewed. The configured machine will
start out with self-signed certificates. Run ,(samp [/usr/bin/acme
renew]) the first time to get CA-issued certificates. Thereafter,
certificates will auto-renew via a cron job.])
(p [When testing your deployment, it might help to start with
the Let's Encrypt staging server as shown below. This will give you
dummy certificates, but will help you avoid running afoul of Let's
Encrypt rate limits. Once you know everything works, delete the ACME
state directory (,(file "/var/lib/acme") by default) and run ,(samp
[/usr/bin/acme renew]) again to get real certificates.]
(prog (source :language scheme
:file "doc/snippets/acme-staging-url.scm")
:line #f))
(p [If you are running guix-forge in a Guix system container, do
remember to mount the ACME state directory (,(file [/var/lib/acme]) by
default) into the container from persistent storage.])))
