```

### Create the gitea user

```bash
useradd gitea
loginctl enable-linger $(id -u gitea)
systemctl --user --machine=gitea@.host enable podman-restart
systemctl --user --machine=gitea@.host enable --now podman.socket
su -l gitea
mkdir -p .config/containers/systemd
mkdir data config postgres
exit
```

### Convert Compose to Quadlet

```bash
# Run this in Homelab, not on the server.
mkdir $(pwd)/active/podman_gitea/quadlets

# Generate the systemd service
podman run \
--network none \
--rm \
-v $(pwd)/active/podman_gitea/compose:$(pwd)/active/podman_gitea/compose:z \
-v $(pwd)/active/podman_gitea/quadlets:$(pwd)/active/podman_gitea/quadlets:z \
quay.io/k9withabone/podlet \
-f $(pwd)/active/podman_gitea/quadlets \
-i \
--overwrite \
compose $(pwd)/active/podman_gitea/compose/compose.yaml

# Copy the files to the server
scp -r $(pwd)/active/podman_gitea/quadlets/. 3dserver:/home/gitea/.config/containers/systemd/
```

### Install Quadlets

First, set up the volumes needed by the container.

```bash
# Enter the container namespace
podman unshare

# Create the volumes
mkdir gitea_data
chown -R 1000:1000 gitea_data
mkdir gitea_etc
chown -R 1000:1000 gitea_etc
exit
```

Now launch the service. The first user you register will be the admin.

```bash
# Create a systemctl viable shell
machinectl shell gitea@
systemctl --user daemon-reload
systemctl --user restart gitea postgres
# Enables auto-update service which will pull new container images automatically every day
systemctl --user enable --now podman-auto-update.timer
```

### Upgrade Quadlets

```bash
scp -r quadlets/. gitea:~/.config/containers/systemd/
ssh gitea systemctl --user daemon-reload
ssh gitea systemctl --user restart gitea postgres
```

### Editing Gitea Config

```bash
# Use podman unshare to work within the container's namespace
podman unshare vim ~/gitea_data/gitea/conf/app.ini
```

## Gitea Runners

<https://docs.gitea.com/next/usage/actions/act-runner/#install-with-the-docker-image>

### Firewall Rules

Since our runner will be contacting our public IP, we need to add a firewall rule to allow
traffic from our DMZ network to our DMZ network. Do this in Unifi or whatever equivalent
you have.

### Install

```bash
touch config.yaml

export GITEA_TOKEN=
docker run \
-v /var/run/docker.sock:/var/run/docker.sock \
-e GITEA_INSTANCE_URL=https://gitea.reeseapps.com \
-e GITEA_RUNNER_REGISTRATION_TOKEN=$GITEA_TOKEN \
-e GITEA_RUNNER_NAME=gitea_runner \
--restart always \
--name gitea_runner \
-d docker.io/gitea/act_runner:latest
```

### Cache Cleanup

Each org or project with a package registry will have its own cleanup rules. For example,
services -> settings -> Packages -> Add Cleanup Rule will allow you to create a cleanup
rule for packages stored under the "services" org. These cleanup rules should run automatically.

You'll need to enable `cron` and `cron.cleanup_packages` in the app.ini (/data/gitea/conf).

Cron: <https://docs.gitea.com/administration/config-cheat-sheet#cron-cron>

Package Cleanup: <https://docs.gitea.com/1.19/administration/config-cheat-sheet#cron---cleanup-hook_task-table-croncleanup_hook_task_table>

```conf
[cron]
ENABLED             = true
RUN_AT_START        = true
NOTICE_ON_SUCCESS   = true
SCHEDULE            = @midnight

[cron.cleanup_packages]
ENABLED             = true
RUN_AT_START        = true
SCHEDULE            = @midnight
NOTICE_ON_SUCCESS   = true
```

On the other hand, the docker builder cache will balloon out of control over time. The gitea
docker runner is handled outside of Gitea's context, so you'll need to clean it up yourself.

```bash
# Check used system resources
docker system df
```

You should run something like this on a schedule:

```bash
# Prune the builder cache
docker builder prune -a
```

To run it every day at noon: `crontab -e`

```bash
0 12 * * * yes | docker builder prune -a
0 12 * * * docker image prune -a -f
```

## Email Notifications

In `/data/gitea/conf/app.ini` add (yes, the `` around the password matters):

```conf
[mailer]
ENABLED        = true
FROM           = gitea@reeseapps.com
PROTOCOL       = smtps
SMTP_ADDR      = email-smtp.us-east-1.amazonaws.com
SMTP_PORT      = 465
USER           = ABC123
PASSWD         = `ABC123...`
```
