Create LXC Containers in ProxMox

February 11, 2024

This is the prefered way to create Docker containers in Proxmox

1. List Available templates

We need to add an Ubuntu and a Rocky Linux Template

ssh root@10.154.2.89

# List available templates
pveam available

Expect to get:

# this iis a shortened list
system          almalinux-9-default_20221108_amd64.tar.xz
system          alpine-3.18-default_20230607_amd64.tar.xz
system          alpine-3.19-default_20240207_amd64.tar.xz

system          rockylinux-9-default_20221109_amd64.tar.xz
system          ubuntu-20.04-standard_20.04-1_amd64.tar.gz
system          ubuntu-22.04-standard_22.04-1_amd64.tar.zst
system          ubuntu-23.04-standard_23.04-1_amd64.tar.zst

# We are going to ignore the turnkeylinux Apliance Templates

2. Download the Ubuntu Template

Select one of the desired above templates : ubuntu-22.04-standard_22.04-1_amd64.tar.zst Run this command :

pveam download local ubuntu-22.04-standard_22.04-1_amd64.tar.zst

pveam download local rockylinux-9-default_20221109_amd64.tar.xz

pveam download local ubuntu-22.04-standard_22.04-1_amd64.tar.zst
pveam download local ubuntu-23.04-standard_23.04-1_amd64.tar.zst

# In mycase I have a 2TB drive : VMdata

pveam download VMdata ubuntu-22.04-standard_22.04-1_amd64.tar.zst

pveam download VMdata rockylinux-9-default_20221109_amd64.tar.xz

3. Creating a Proxmoc LXC Container

Select template from these : 
ubuntu-22.04-standard_22.04-1_amd64.tar.zst
rockylinux-9-default_20221109_amd64.tar.xz

-> Next
Disk size:(GiB) : 20
