# Prerequisites for Installing YAMS in a Proxmox LXC
|
|
|
|
If you plan to install YAMS inside a Proxmox LXC container, some specific host-level configuration is required **before** you run the YAMS installation script. These steps ensure Docker and the VPN component (Gluetun) can function correctly within the LXC environment by providing access to the necessary TUN device.
|
|
|
|
> **Note:** This guide is based on the solution discovered and shared by forum user **Bobs_Manager**. You can find the original discussion [here on the YAMS Forum](https://forum.yams.media/viewtopic.php?t=212).
|
|
|
|
⚠️ **Important:** Only use an **unprivileged** LXC container for YAMS. Privileged containers pose significant security risks and are not recommended.
|
|
|
|
Follow these steps on your Proxmox **host** system:
|
|
|
|
1. **Access the Proxmox Host Shell:** Log into your Proxmox server via SSH or use the web UI's shell access for the node (not the LXC console).
|
|
|
|
2. **Edit the LXC Configuration File:** Open the configuration file specific to the LXC container where you intend to install YAMS. Replace `<container-ID>` with the actual numeric ID of your LXC container.
|
|
```bash
|
|
nano /etc/pve/lxc/<container-ID>.conf
|
|
```
|
|
|
|
3. **Add Configuration Lines:** Append the following lines to the **end** of the file. These lines grant the container necessary permissions and crucially mount the `/dev/net/tun` device from the host into the container.
|
|
```ini
|
|
lxc.cgroup.devices.allow: a
|
|
lxc.cap.drop:
|
|
lxc.cgroup2.devices.allow: c 10:200 rwm
|
|
lxc.mount.entry: /dev/net/tun dev/net/tun none bind,create=file
|
|
```
|
|
Your configuration file should now look similar to this at the end:
|
|
[](/pics/proxmox-lxc-config.png)
|
|
|
|
4. **Save and Close:** Save the changes to the configuration file and exit the editor.
|
|
|
|
5. **Restart the LXC Container:** For the changes to take effect, you must restart the LXC container. You can do this via the Proxmox web UI or using the following commands on the Proxmox host:
|
|
```bash
|
|
pct stop <container-ID>
|
|
pct start <container-ID>
|
|
```
|
|
|
|
## Next Steps
|
|
|
|
After completing these prerequisites and restarting the LXC container, you can now log into the LXC container's console and proceed with the standard YAMS installation as described in the [Installation Guide](/install/steps/).
