🚀 LXC AutoScale

LXC AutoScale is a resource management daemon specifically designed for Proxmox environments. It automatically adjusts CPU and memory allocations with no downtime and can clone LXC containers based on real-time usage metrics and predefined thresholds. Can be run locally or remotely to make your containers always optimized for performance, managing spikes in demand, and optionally preserving resources during off-peak hours.

• ✅ Works with Proxmox 8.2.4

Quick Start

Features

[!NOTE] If You need to autoscale Virtual Machines resources on Proxmox hosts You will like this project.

Quick Start

Getting started with LXC AutoScale on your Proxmox host is quick and simple:

curl -sSL https://raw.githubusercontent.com/fabriziosalmi/proxmox-lxc-autoscale/main/install.sh | bash

[!TIP] Once installed, the service should be up and running. You can verify this by executing:

systemctl status lxc_autoscale.service

If the conditions set in the configuration are met, you will quickly observe scaling operations in action.

[!IMPORTANT] You need to check your /lib/systemd/system/lxcfs.service file for the presence of the -l option which makes loadavg retrieval working as expected. Here the required configuration:

[Unit]
Description=FUSE filesystem for LXC
ConditionVirtualization=!container
Before=lxc.service
Documentation=man:lxcfs(1)

[Service]
OOMScoreAdjust=-1000
ExecStartPre=/bin/mkdir -p /var/lib/lxcfs
# ExecStart=/usr/bin/lxcfs /var/lib/lxcfs
ExecStart=/usr/bin/lxcfs /var/lib/lxcfs -l
KillMode=process
Restart=on-failure
ExecStopPost=-/bin/fusermount -u /var/lib/lxcfs
Delegate=yes
ExecReload=/bin/kill -USR1 $MAINPID

[Install]
WantedBy=multi-user.target

Just update the /lib/systemd/system/lxcfs.service file, execute systemctl daemon-reload && systemctl restart lxcfs and when you are ready to apply the fix restart the LXC containers.

Tnx to No-Pen9082 to point me out to that. Here the Proxmox forum thread on the topic.

Configuration

LXC AutoScale is designed to be highly customizable. You can reconfigure the service at any time to better suit your specific needs. For detailed instructions on how to adjust the settings, please refer to the official documentation.

[!TIP] If You need LXC AutoScale configuration for all your LXC containers You can automatically generate it by running this command:

curl -sSL https://raw.githubusercontent.com/fabriziosalmi/proxmox-lxc-autoscale/main/lxc_autoscale/lxc_autoscale_autoconf.sh | bash

Additional resources

LXC AutoScale and LXC AutoScale ML can be used and extended in many ways, here some useful additional resources:

• 🌐 LXC AutoScale UI - Simple web UI to check scaling actions and logs
• 🎛️ LXC AutoScale - TIER snippets for 40 self-hosted apps

[!TIP] LXC AutoScale ML has been finally moved to a new, separate repository.
