Downloading Proxmox Container images

Before you can create a LXC container on a Proxmox virtualized environment, you need to download the template images first from an available list. You need to pre-download the images first befoe you can create new containers from them in the web ui.

From the docs here, there steps are (while ssh’d into your Proxmox server):

Update catalog of available templates:

pveam update

List the available templates:

root@pve:~# pveam available

system          alpine-3.3-default_20160427_amd64.tar.xz

system          alpine-3.4-default_20161206_amd64.tar.xz

system          alpine-3.5-default_20170504_amd64.tar.xz

system          archlinux-base_20170704-1_amd64.tar.gz

system          centos-6-default_20161207_amd64.tar.xz

system          centos-7-default_20170504_amd64.tar.xz

system          debian-6.0-standard_6.0-7_amd64.tar.gz

system          debian-7.0-standard_7.11-1_amd64.tar.gz

system          debian-8.0-standard_8.7-1_amd64.tar.gz

system          debian-9.0-standard_9.0-2_amd64.tar.gz

system          fedora-24-default_20161207_amd64.tar.xz

system          fedora-25-default_20170316_amd64.tar.xz

system          gentoo-current-default_20170503_amd64.tar.xz

system          opensuse-42.2-default_20170406_amd64.tar.xz

system          ubuntu-12.04-standard_12.04-1_amd64.tar.gz

system          ubuntu-14.04-standard_14.04-1_amd64.tar.gz

system          ubuntu-16.04-standard_16.04-1_amd64.tar.gz

system          ubuntu-16.10-standard_16.10-1_amd64.tar.gz

system          ubuntu-17.04-standard_17.04-1_amd64.tar.gz

For each of the templates you wish to use, download using for example for Ubuntu 14.04:

pveam download local ubuntu-14.04-standard_14.04-1_amd64.tar.gz

Now from the web ui, you should be able to click the ‘Create CT’ button and pick from your available templates:

Getting past Vagrant’s “Authentication failure” error when starting up OpenShift Origin

For getting up and running quickly with OpenShift Origin, RedHat have an all-in-one VM image you can provision with Vagrant. The instructions mention to not use Vagrant 1.8.5 as there’s an issue with the SSH setup – since I already had 1.8.5 installed for some other projects, I tried anyway, and ran into issues with SSH’ing into the VM with SSH keys.

When provisioning the VM, you’ll see:

 

Kevins-MacBook-Pro:openshift-origin kev$ vagrant up
Bringing machine 'default' up with 'virtualbox' provider...
==> default: Checking if box 'openshift/origin-all-in-one' is up to date...
==> default: Resuming suspended VM...
==> default: Booting VM...

    default: SSH username: vagrant
    default: SSH auth method: private key
    default: Warning: Authentication failure. Retrying...
    default: Warning: Authentication failure. Retrying...

There’s a number of posts discussing this issue and a few workarounds, for example, here and here.

The suggestions relate to switching from the ssh authentication to userid/password, by adding this to your Vagrantfile:

config.ssh.username = "vagrant"
config.ssh.password = "vagrant"

I tried this, and when running vagrant up I had different errors about “SSH authentication failed”. Next I tried adding this recommendation:

 

config.ssh.insert_key = false

This didn’t make any difference initially, but doing a vagrant destroy, and then trying to bring it up again initially ran into the same issue, I Ctrl-C’d out and tried again and then it worked second time. I’m not sure what steps got past the ssh keys issue, but at this point I was up and running. There’s a long discussion in both the linked threads above that describe the cause of the issue, so if you’re interested take a look through those threads.
