# Forgejo Service {#services-forgejo}
Defined in [`/modules/services/forgejo.nix`](@REPO@/modules/services/forgejo.nix).
This NixOS module is a service that sets up a [Forgejo](https://forgejo.org/) instance.
Compared to the stock module from nixpkgs,
this one sets up, in a fully declarative manner,
LDAP and SSO integration as well as one local runner.
## Features {#services-forgejo-features}
- Declarative creation of users, admin or not.
- Also declarative [LDAP](#services-forgejo-options-shb.forgejo.ldap) Configuration. [Manual](#services-forgejo-usage-ldap).
- Declarative [SSO](#services-forgejo-options-shb.forgejo.sso) Configuration. [Manual](#services-forgejo-usage-sso).
- Declarative [local runner](#services-forgejo-options-shb.forgejo.localActionRunner) Configuration.
- Access through [subdomain](#services-forgejo-options-shb.forgejo.subdomain) using reverse proxy. [Manual](#services-forgejo-usage-configuration).
- Access through [HTTPS](#services-forgejo-options-shb.forgejo.ssl) using reverse proxy. [Manual](#services-forgejo-usage-configuration).
- [Backup](#services-forgejo-options-shb.forgejo.sso) through the [backup block](./blocks-backup.html). [Manual](#services-forgejo-usage-backup).
- Integration with the [dashboard contract](contracts-dashboard.html) for displaying user facing application in a dashboard. [Manual](#services-forgejo-usage-applicationdashboard)
## Usage {#services-forgejo-usage}
### Initial Configuration {#services-forgejo-usage-configuration}
The following snippet enables Forgejo and makes it available under the `forgejo.example.com` endpoint.
```nix
shb.forgejo = {
enable = true;
subdomain = "forgejo";
domain = "example.com";
users = {
"theadmin" = {
isAdmin = true;
email = "theadmin@example.com";
password.result = config.shb.sops.secret.forgejoAdminPassword.result;
};
"theuser" = {
email = "theuser@example.com";
password.result = config.shb.sops.secret.forgejoUserPassword.result;
};
};
};
shb.sops.secret."forgejo/admin/password" = {
request = config.shb.forgejo.users."theadmin".password.request;
};
shb.sops.secret."forgejo/user/password" = {
request = config.shb.forgejo.users."theuser".password.request;
};
```
Two users are created, `theadmin` and `theuser`,
respectively with the passwords `forgejo/admin/password`
and `forgejo/user/password` from a SOPS file.
This assumes secrets are setup with SOPS
as mentioned in [the secrets setup section](usage.html#usage-secrets) of the manual.
Secrets can be randomly generated with `nix run nixpkgs#openssl -- rand -hex 64`.
### Forgejo through HTTPS {#services-forgejo-usage-https}
:::: {.note}
We will build upon the [Initial Configuration](#services-forgejo-usage-configuration) section,
so please follow that first.
::::
If the `shb.ssl` block is used (see [manual](blocks-ssl.html#usage) on how to set it up),
the instance will be reachable at `https://forgejo.example.com`.
Here is an example with Let's Encrypt certificates, validated using the HTTP method:
```nix
shb.certs.certs.letsencrypt."example.com" = {
domain = "example.com";
group = "nginx";
reloadServices = [ "nginx.service" ];
adminEmail = "myemail@mydomain.com";
};
```
Then you can tell Forgejo to use those certificates.
```nix
shb.certs.certs.letsencrypt."example.com".extraDomains = [ "forgejo.example.com" ];
shb.forgejo = {
ssl = config.shb.certs.certs.letsencrypt."example.com";
};
```
### With LDAP Support {#services-forgejo-usage-ldap}
:::: {.note}
We will build upon the [HTTPS](#services-forgejo-usage-https) section,
so please follow that first.
::::
We will use the [LLDAP block][] provided by Self Host Blocks.
Assuming it [has been set already][LLDAP block setup], add the following configuration:
[LLDAP block]: blocks-lldap.html
[LLDAP block setup]: blocks-lldap.html#blocks-lldap-global-setup
```nix
shb.forgejo.ldap = {
enable = true;
host = "127.0.0.1";
port = config.shb.lldap.ldapPort;
dcdomain = config.shb.lldap.dcdomain;
adminPassword.result = config.shb.sops.secret."forgejo/ldap/adminPassword".result
};
shb.sops.secret."forgejo/ldap/adminPassword" = {
request = config.shb.forgejo.ldap.adminPassword.request;
settings.key = "ldap/userPassword";
};
```
The `shb.forgejo.ldap.adminPasswordFile` must be the same
as the `shb.lldap.ldapUserPasswordFile` which is achieved
with the `key` option.
The other secrets can be randomly generated with
`nix run nixpkgs#openssl -- rand -hex 64`.
And that's it.
Now, go to the LDAP server at `http://ldap.example.com`,
create the `forgejo_user` and `forgejo_admin` groups,
create a user and add it to one or both groups.
When that's done, go back to the Forgejo server at
`http://forgejo.example.com` and login with that user.
### With SSO Support {#services-forgejo-usage-sso}
:::: {.note}
We will build upon the [LDAP](#services-forgejo-usage-ldap) section,
so please follow that first.
::::
We will use the [SSO block][] provided by Self Host Blocks.
Assuming it [has been set already][SSO block setup], add the following configuration:
[SSO block]: blocks-sso.html
[SSO block setup]: blocks-sso.html#blocks-sso-global-setup
```nix
shb.forgejo.sso = {
enable = true;
endpoint = "https://${config.shb.authelia.subdomain}.${config.shb.authelia.domain}";
secretFile = <path/to/oidcForgejoSharedSecret>;
secretFileForAuthelia = <path/to/oidcForgejoSharedSecret>;
};
```
Passing the `ssl` option will auto-configure nginx to force SSL connections with the given
certificate.
The `shb.forgejo.sso.secretFile` and `shb.forgejo.sso.secretFileForAuthelia` options
must have the same content. The former is a file that must be owned by the `forgejo` user while
the latter must be owned by the `authelia` user. I want to avoid needing to define the same secret
twice with a future secrets SHB block.
### SMTP {#services-forgejo-usage-smtp}
To send e-mails, notifications, define the SMTP settings like so:
```nix
{
services.forgejo = {
smtp = {
host = "smtp.mailgun.org";
port = 587;
username = "postmaster@mg.${domain}";
from_address = "authelia@${domain}";
password.result = config.shb.sops.secret."forgejo/smtpPassword".result;
};
};
shb.sops.secret."forgejo/smtpPassword" = {
request = config.shb.forgejo.smtp.password.request;
};
}
```
### Backup {#services-forgejo-usage-backup}
Every hour, Forgejo takes a backup using the [built-in `dump` command](https://forgejo.org/docs/latest/admin/command-line/#dump).
This backup is ephemeral and should be moved in a permanent location.
This can be accomplished using the following config.
Backing up Forgejo using the [Restic block](blocks-restic.html) is done like so:
```nix
shb.restic.instances."forgejo" = {
request = config.shb.forgejo.backup;
settings = {
enable = true;
};
};
```
The name `"forgejo"` in the `instances` can be anything.
The `config.shb.forgejo.backup` option provides what directories to backup.
You can define any number of Restic instances to backup Forgejo multiple times.
### Application Dashboard {#services-forgejo-usage-applicationdashboard}
Integration with the [dashboard contract](contracts-dashboard.html) is provided
by the [dashboard option](#services-forgejo-options-shb.forgejo.dashboard).
For example using the [Homepage](services-homepage.html) service:
```nix
{
shb.homepage.servicesGroups.Admin.services.Forgejo = {
sortOrder = 1;
dashboard.request = config.shb.forgejo.dashboard.request;
};
}
```
### Extra Settings {#services-forgejo-usage-extra-settings}
Other Forgejo settings can be accessed through the nixpkgs [stock service][].
[stock service]: https://search.nixos.org/options?channel=24.05&from=0&size=50&sort=alpha_asc&type=packages&query=services.forgejo
## Debug {#services-forgejo-debug}
In case of an issue, check the logs for systemd service `forgejo.service`.
Enable verbose logging by setting the `shb.forgejo.debug` boolean to `true`.
Access the database with `sudo -u forgejo psql`.
