### Container Registry

As container registry we make use of the [Docker Registry 2.0](https://hub.docker.com/_/registry/)
implementation for storing and distributing container images

The container registry API is available at <https://registry.ublue.local/v2>

### Anvil

The blacksmith's work is done with [Ansible](https://docs.ansible.com/ansible/latest/index.html).

The shiny GUI is missing but this should not shy us away. See [usage](#usage) for instructions.
There are two methods of operating the forge, either via a GUI available at <https://forge.ublue.local>
or via [just command runner](https://github.com/casey/just).

Detailed usage instructions are available in the [documentation](./docs/index.md) section.

## Handling the forge

You can use the `forge.sh` to **setup**, **heat-up** and **cool-down** the forge.

### Usage

Once the forge has been setup the following recipes are available via [just command runner](https://github.com/casey/just).

<!-- markdownlint-disable MD013 -->

| Just recipe | Input argument | Default argument value | Description |
| --------------------- | ----------------------- | ------------------------------------------- | -------------------------------------------- |

| `forge_project-build` | `forge_config_var_file` | $HOME/ublue-os_forge/forge_default_vars.env | Build container image and upload to registry |

<!-- markdownlint-enable MD013 -->

All available settings for the `forge_config_var_file` are documented in the [variables.md](./docs/variables.md)
file. To launch a recipe you simple run:

```sh
just -f forge.just {{ recipe_name }} {{ forge_config_var_file }}
```

**_Example:_**

```sh
just -f forge.just forge_project-clone ~/ublue-os_forge/my-forge-project.env
```

In case you don't have [just command runner](https://github.com/casey/just) available.
Have a look at the [forge.just](./forge.just) file. It easy enough to understand which commands
are executed via the just recipes.

# Universal Blue - Forge

On-premises Universal Blue. This repository is intended to provide the service units
necessary to set up a self-hosted OS forge for custom images.

## Configuration

Since we are using ansible in the background, all user configurations are loaded via
[`extra-vars`](https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_variables.html#defining-variables-at-runtime)
at runtime. No worries on how things are plugged together, you only have to know where
to create your configuration files. That's all.

So, during forge setup a podman volume `ublue-os_forge-data` is created. All user configuration
etc. is stored there. You can inspect the volume with:

```sh
❯ podman volume inspect ublue-os_forge-data
[
{
"Name": "ublue-os_forge-data",
"Driver": "local",
"Mountpoint": "/var/home/stephan/.local/share/containers/storage/volumes/ublue-os_forge-data/_data",
"CreatedAt": "2024-05-06T21:25:28.818751853+02:00",
"Labels": {},
"Scope": "local",
"Options": {},
"MountCount": 0,
"NeedsCopyUp": true,
"LockNumber": 98
}
]
```

Under the `"Mountpoint:"` you find the actual path on your file system. I would recommend you
symlink this folder to a path more rememberable. For example you can do:

```sh
FORGE_POD_DATA_DIR="$(podman volume inspect ublue-os_forge-data | jq -r '.[0].Mountpoint')"
ln -s $FORGE_POD_DATA_DIR $HOME/ublue-os_forge-data
```

In that folder you will find an example configuration similar to this:

```yaml
## ublue-os forge extra-vars example configuration
## For more details got to https://github.com/ublue-os/forge/blob/main/docs/variables.md
---
forge_git_repository_url: https://github.com/ublue-os/bluefin.git
forge_git_repository_destination: /var/home/stephan/.local/share/containers/storage/volumes/ublue-os_forge-data/_data/data/bluefin
forge_git_repository_version: main
forge_registry_url: registry.ublue.local
```
This file acts as a template. Simple copy it and modify it to your liking. For each project
you want to handle with the forge you can create a dedicated file.
Details about the available variables are documented [here](./variables.md).
## Usage
There are two methods of operating the forge, either via a GUI available at <https://forge.ublue.local>
or via [just command runner](https://github.com/casey/just).
More details about either usage are available here:
- [GUI](./gui.md)
- [just command runner](./just.md)

# Usage with just command runner

If you don't want to use the [GUI](gui.md) we provide the following recipes
via [just command runner](https://github.com/casey/just).

<!-- markdownlint-disable MD013 -->

| Just recipe | Input argument | Description |
| --------------------- | ----------------------- | -------------------------------------------- |
| `forge_project-clone` | `forge_config_var_file` | Clone git project repository |
| `forge_project-build` | `forge_config_var_file` | Build container image and upload to registry |

<!-- markdownlint-enable MD013 -->

All available settings for the `forge_config_var_file` are documented in the [variables.md](./variables.md)
file. To launch a recipe you simple run:

```sh
just -f forge.just {{ recipe_name }} {{ forge_config_var_file }}
```

**_Example:_**

```sh
just -f forge.just forge_project-clone ~/ublue-os_forge/my-forge-project.env
```

In case you don't have [just command runner](https://github.com/casey/just) available.
Have a look at the [forge.just](../forge.just) file. It easy enough to understand which commands
are executed via the just recipes.
