psviderski/uncloud v0.17.1

on GitHub

This is small patch release that adds WireGuard endpoint management for machines, Compose stop_grace_period support, and several networking fixes.

WireGuard endpoint management

You can now manually specify what WireGuard endpoint to use when adding or initialising a machine instead of relying on auto-detection. This is useful when a machine is behind a NAT or has multiple network interfaces.

uc machine init user@host --wg-endpoint 203.0.113.1
uc machine add user@host --wg-endpoint 203.0.113.2 --wg-endpoint 192.168.1.5

You can also update the WireGuard endpoint for an existing machine:

uc machine update my-machine --wg-endpoint 203.0.113.1

Compose stop_grace_period support

Control how long to wait before sending SIGKILL to a container during replacements and stops.

services:
  app:
    image: myapp
    stop_grace_period: 30s

Improvements

• Tailscale addresses are excluded from auto-detected WireGuard endpoints: see Discord thread
• uc logs now prints a warning and continues instead of failing when some Compose services are not found in the cluster
• Improved reliability of the initial cluster store sync by waiting for known missing changes
• Removed the obsolete uc machine token command

Bug fixes

• Fixed Uncloud DNS resolution for IPv6 machines by creating AAAA records: #257
• Fixed connection formatting when changing connection with uc ctx conn

Upgrade to 0.17.1
