psviderski/uncloud v0.10.0

on GitHub

This release introduces new machine management commands (rm, rename, update) and extends Docker Compose support.
Also, includes important bug fixes for machines using UFW firewall and race conditions during cluster initialisation.

✨ We also launched a new blog and published our first post: How to connect Docker containers across multiple hosts with WireGuard

Upgrade to 0.10.0

Uncloud CLI locally

To upgrade the Uncloud CLI (uc) locally:

# 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:

# AMD64
curl -fsSL -o uncloudd.tar.gz https://github.com/psviderski/uncloud/releases/download/v0.10.0/uncloudd_linux_amd64.tar.gz
# ARM64
# curl -fsSL -o uncloudd.tar.gz https://github.com/psviderski/uncloud/releases/download/v0.10.0/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

New features

Machine management

• Added uc machine rm command to remove machines from the cluster and reset them to a clean state.
• Added uc machine rename command to rename machines.
• Added uc machine update command to update a public IP address of a machine used for registering machines in Uncloud DNS service (uc dns).

Docker Compose enhancements

• Support for x-machines placement constraints in Compose files, allowing you to control which machines services are deployed to (#90).
• Containers with pull_policy: always are now properly recreated on deployment to ensure the latest image is used (#100).

Bug fixes

• Fixed machine initialisation when UFW firewall is active by properly allowing IPv6 management traffic (#65).
• Resolved race condition during cluster initialisation by waiting for the corrosion service to be ready with schema applied (#89).
• Fixed race condition that could occur during Docker network creation.

Improvements

• Disabled masquerading for container IPs when communicating via WireGuard overlay network.
