# Manifests for rpm-ostree based Fedora variants

This is the configuration needed to create
[rpm-ostree](https://coreos.github.io/rpm-ostree/) based variants of Fedora.
Each variant is described in a YAML
[treefile](https://coreos.github.io/rpm-ostree/treefile/) which is then used by
rpm-ostree to compose an ostree commit with the package requested.

In the Fedora infrastructure, this happens via
[pungi](https://pagure.io/pungi-fedora) with
[Lorax](https://github.com/weldr/lorax)
([templates](https://pagure.io/fedora-lorax-templates)).

## Building

Instructions to perform a local build of Silverblue:

```
# Clone the config
git clone https://pagure.io/workstation-ostree-config && cd workstation-ostree-config

# Prepare directories
mkdir -p repo cache
ostree --repo=repo init --mode=archive

# Build (compose) the variant of your choice
sudo rpm-ostree compose tree --repo=repo --cachedir=cache fedora-silverblue.yaml

# Update summary file
ostree summary --repo=repo --update
```

## Testing

Instructions to test the resulting build:

- First, serve the ostree repo using an HTTP server. You can use any static file server. For example using <https://github.com/TheWaWaR/simple-http-server>:

  ```
  simple-http-server --index --ip 192.168.122.1 --port 8000
  ```

- Then, on an already installed Silverblue system:

```
# Add an ostree remote
sudo ostree remote add testremote http://192.168.122.1:8000/repo --no-gpg-verify

# Pin the currently deployed (and probably working) version
sudo ostree admin pin 0

# List refs from variant remote
sudo ostree remote refs testremote

# Switch to your variant
sudo rpm-ostree rebase testremote:fedora/rawhide/x86_64/silverblue

# Reboot and test!
```
