v0.9.0

# Uncloud 0.9.0 Release Notes

This release includes critical Docker 28.2.0+ compatibility fixes, sets better defaults for container logging, and includes minor housekeeping improvements.

## Upgrade to 0.9.0

### Uncloud CLI locally

To upgrade the Uncloud CLI (`uc`) locally:

```bash
# Homebrew (macOS, Linux)
brew upgrade uncloud

# Install script (macOS, Linux)
curl -fsS https://get.uncloud.run/install.sh | sh
```

### Machine daemon

To upgrade the Uncloud daemon on your machines, run the following commands on each machine:

```bash
# AMD64
curl -fsSL -o uncloudd.tar.gz https://github.com/psviderski/uncloud/releases/download/v0.9.0/uncloudd_linux_amd64.tar.gz
# ARM64
# curl -fsSL -o uncloudd.tar.gz https://github.com/psviderski/uncloud/releases/download/v0.9.0/uncloudd_linux_arm64.tar.gz
tar -xf uncloudd.tar.gz
sudo install uncloudd /usr/local/bin/uncloudd
rm uncloudd uncloudd.tar.gz
sudo systemctl restart uncloud
```

## Bug fixes

### Docker 28.2.0+ compatibility

Fixed connectivity between containers across machines with Docker 28.2.0 and later versions. The fix only works for **new** clusters and **new** machines added to existing clusters.

Starting with Docker 28.2.0 (https://github.com/moby/moby/pull/49832), Docker networks must explicitly specify from which host interfaces they allow [direct routing](https://docs.docker.com/engine/network/packet-filtering-firewalls/#direct-routing) to their containers. This is done by specifying the `com.docker.network.bridge.trusted_host_interfaces` option when creating the network. We now create the `uncloud` Docker network with `com.docker.network.bridge.trusted_host_interfaces=uncloud` option to allow the WireGuard mesh network (`uncloud` interface) to route traffic to uncloud-managed containers.

If you **upgraded Docker to 28.2.0 or a later version on an existing machine**, you need to manually recreate the `uncloud` Docker network with the `com.docker.network.bridge.trusted_host_interfaces=uncloud` option on it to fix cross-machine communication. We prepared the [migration script](https://github.com/psviderski/uncloud/blob/main/scripts/migrate_docker_28.2.0.sh) that will do that for you.
**⚠️ Note:** the migration process may cause temporary service disruption. Download and run it on your machines:

```
curl -O https://raw.githubusercontent.com/psviderski/uncloud/refs/heads/main/scripts/migrate_docker_28.2.0.sh
chmod +x migrate_docker_28.2.0.sh
sudo ./migrate_docker_28.2.0.sh
rm migrate_docker_28.2.0.sh
```

## New features

* The default log driver for all service containers is set to [`local`](https://docs.docker.com/engine/logging/drivers/local/), which preserves 100MB of log messages per container and uses automatic compression to reduce the size on disk. There is no longer a need to manually specify the log driver limits to prevent logs from filling up the disk space. Contributed by @zasdaym.
* Added unofficial [Debian package repository](https://github.com/dariogriffo/uncloud-debian/) maintained by @dariogriffo.

## Improvements

* Uncloud-managed volumes are labeled with `uncloud.managed` to make it easier to identify and manage them.
* Anonymous volumes are now properly cleaned up when removing service containers.

## Developer Experience

* Protobuf compiler and Go plugins are now managed through [`mise`](https://mise.jdx.dev/), using consistent versions across all development environments.
* Added CI checks for protobuf generation on multiple platforms.
* Added `.editorconfig` for consistent code formatting across different editors.
