Are there any pre-steps before installing docker on a new Proxmox Installation?

[siniradam]

I'm pretty new to proxmox, used a video tutorial on youtube. Succesfuly installed, ubuntu, windows, TrueNAS.
When I try to install Docker w/ this

bash -c "$(wget -qLO - https://github.com/tteck/Proxmox/raw/main/ct/docker.sh)"

Wizard starts, and pick values like this;

• var_disk="20"
• var_cpu="3"
• var_ram="3072"
• var_os="ubuntu"
• var_version="23.04"

After the last step, I'm getting this error message;
"Unable to detect a valid Container Storage location"

Tried running

pvesm status -content rootdir | awk 'NR>1'

I doesn't return anything, when I try the next command, the result is below;

pvesm status -content vztmpl | awk 'NR>1'
local         dir     active       951541116        52943588       858882592    5.56%

This command cat /sys/module/kvm_amd/parameters/nested returns 1 which should mean virtualization is enabled.

proxmox-ve: 8.1.0 (running kernel: 6.5.13-1-pve)
pve-manager: 8.1.4 (running version: 8.1.4/ec5affc9e41f1d79)

System Details goes like this;

• BIOS Model name: AMD Ryzen 7 5800H with Radeon Graphics Unknown CPU @ 3.2GHz
• Virtualization: AMD-V

Am I missing a step, are there any other steps that I need to take before creating Docker Container?

By any chance, was that video by NetworkChuck?

[siniradam]

Indeed it is NetworkChuck.

Based on my advice, reinstalling Proxmox is necessary. It seems that following NetworkChuck's suggestion to delete the local-lvm storage has led you astray, as you're now discovering.

[siniradam]

I knew something was wrong. It didn't feel right. Would you care to explain what's going on behind the scenes briefly or can you point me in the direction of what I need to search for?

Aside from reinstalling, if there is a way to fix it by creating local-lvm again, would that be a bad idea? Considering I've already installed other VMs.

[tteck]

Local-LVM storage typically provides better performance compared to standard file-based storage, as it uses block devices directly. This can lead to faster read and write operations, which is especially important for I/O-intensive workloads.

With Local-LVM, you can isolate storage for each virtual machine or container using logical volumes. This helps prevent one VM or container from impacting others in terms of storage I/O or running out of disk space.

Using Local-LVM helps reduce file system fragmentation, which can improve performance and storage efficiency.

What does the command pvesm status show?

[siniradam]

The result is as below.

Name         Type     Status           Total            Used       Available        %
local         dir     active       951541116        52966760       858859420    5.57%

Never delete local-lvm!
