Installs and configures a Proxmox 5.x/6.x cluster with the following features:
- Ensures all hosts can connect to one another as root
- Ability to create/manage groups, users, access control lists and storage
- Ability to create or add nodes to a PVE cluster
- Ability to setup Ceph on the nodes
- IPMI watchdog support
- BYO HTTPS certificate support
- Ability to use either
pve-no-subscription
orpve-enterprise
repositories
The primary goal for this role is to configure and manage a Proxmox VE cluster (see example playbook), however this role can be used to quickly install single node Proxmox servers.
I'm assuming you already have Ansible installed. You will need to use an external machine to the one you're installing Proxmox on (primarily because of the reboot in the middle of the installation, though I may handle this somewhat differently for this use case later).
Copy the following playbook to a file like install_proxmox.yml
:
- hosts: all
become: True
roles:
- {
role: geerlingguy.ntp,
ntp_manage_config: true,
ntp_servers: [
clock.sjc.he.net,
clock.fmt.he.net,
clock.nyc.he.net
]
}
- {
role: lae.proxmox,
pve_group: all,
pve_reboot_on_kernel_update: true
}
Install this role and a role for configuring NTP:
ansible-galaxy install lae.proxmox geerlingguy.ntp
Now you can perform the installation:
ansible-playbook install_proxmox.yml -i $SSH_HOST_FQDN, -u $SSH_USER
If your SSH_USER
has a sudo password, pass the -K
flag to the above command.
If you also authenticate to the host via password instead of pubkey auth, pass
the -k
flag (make sure you have sshpass
installed as well). You can set
those variables prior to running the command or just replace them. Do note the
comma is important, as a list is expected (otherwise it'll attempt to look up a
file containing a list of hosts).
Once complete, you should be able to access your Proxmox VE instance at
https://$SSH_HOST_FQDN:8006
.

Create a new playbook directory. We call ours lab-cluster
. Our playbook will
eventually look like this, but yours does not have to follow all of the steps:
lab-cluster/
├── files
│ └── pve01
│ ├── lab-node01.local.key
│ ├── lab-node01.local.pem
│ ├── lab-node02.local.key
│ ├── lab-node02.local.pem
│ ├── lab-node03.local.key
│ └── lab-node03.local.pem
├── group_vars
│ ├── all
│ └── pve01
├── inventory
├── roles
│ └── requirements.yml
├── site.yml
└── templates
└── interfaces-pve01.j2
6 directories, 12 files
First thing you may note is that we have a bunch of .key
and .pem
files.
These are private keys and SSL certificates that this role will use to configure
the web interface for Proxmox across all the nodes. These aren't necessary,
however, if you want to keep using the signed certificates by the CA that
Proxmox sets up internally. You may typically use Ansible Vault to encrypt the
private keys, e.g.:
ansible-vault encrypt files/pve01/*.key
This would then require you to pass the Vault password when running the playbook.
Let's first specify our cluster hosts. Our inventory
file may look like this:
[pve01]
lab-node01.local
lab-node02.local
lab-node03.local
You could have multiple clusters, so it's a good idea to have one group for each
cluster. Now, let's specify our role requirements in roles/requirements.yml
:
---
- src: geerlingguy.ntp
- src: lae.proxmox
We need an NTP role to configure NTP, so we're using Jeff Geerling's role to do so. You wouldn't need it if you already have NTP configured or have a different method for configuring NTP.
Now, let's specify some group variables. First off, let's create group_vars/all
for setting NTP-related variables:
---
ntp_manage_config: true
ntp_servers:
- lab-ntp01.local iburst
- lab-ntp02.local iburst
Of course, replace those NTP servers with ones you prefer.
Now for the flesh of your playbook, pve01
's group variables. Create a file
group_vars/pve01
, add the following, and modify accordingly for your environment.
---
pve_group: pve01
pve_watchdog: ipmi
pve_ssl_private_key: "{{ lookup('file', pve_group + '/' + inventory_hostname + '.key') }}"
pve_ssl_certificate: "{{ lookup('file', pve_group + '/' + inventory_hostname + '.pem') }}"
pve_cluster_enabled: yes
pve_groups:
- name: ops
comment: Operations Team
pve_users:
- name: admin1@pam
email: [email protected]
firstname: Admin
lastname: User 1
groups: [ "ops" ]
- name: admin2@pam
email: [email protected]
firstname: Admin
lastname: User 2
groups: [ "ops" ]
pve_acls:
- path: /
roles: [ "Administrator" ]
groups: [ "ops" ]
pve_storages:
- name: localdir
type: dir
content: [ "images", "iso", "backup" ]
path: /plop
maxfiles: 4
pve_ssh_port: 22
interfaces_template: "interfaces-{{ pve_group }}.j2"
pve_group
is set to the group name of our cluster, pve01
- it will be used
for the purposes of ensuring all hosts within that group can connect to each
other and are clustered together. Note that the PVE cluster name will be set to
this group name as well, unless otherwise specified by pve_cluster_clustername
.
Leaving this undefined will default to proxmox
.
pve_watchdog
here enables IPMI watchdog support and configures PVE's HA
manager to use it. Leave this undefined if you don't want to configure it.
pve_ssl_private_key
and pve_ssl_certificate
point to the SSL certificates for
pvecluster. Here, a file lookup is used to read the contents of a file in the
playbook, e.g. files/pve01/lab-node01.key
. You could possibly just use host
variables instead of files, if you prefer.
pve_ssl_letsencrypt
allows to obtain a Let's Encrypt SSL certificate for
pvecluster. The Ansible role systemli.letsencrypt
needs to be installed first in order to use this function.
pve_cluster_enabled
enables the role to perform all cluster management tasks.
This includes creating a cluster if it doesn't exist, or adding nodes to the
existing cluster. There are checks to make sure you're not mixing nodes that
are already in existing clusters with different names.
pve_groups
, pve_users
, and pve_acls
authorizes some local UNIX users (they
must already exist) to access PVE and gives them the Administrator role as part
of the ops
group. Read the User and ACL Management section for more info.
pve_storages
allows to create different types of storage and configure them.
The backend needs to be supported by Proxmox.
Read the Storage Management section for more info.
pve_ssh_port
allows you to change the SSH port. If your SSH is listening on
a port other than the default 22, please set this variable. If a new node is
joining the cluster, the PVE cluster needs to communicate once via SSH.
pve_manage_ssh
(default true) allows you to disable any changes this module
would make to your SSH server config. This is useful if you use another role
to manage your SSH server. Note that setting this to false is not officially
supported, you're on your own to replicate the changes normally made in
ssh_cluster_config.yml.
interfaces_template
is set to the path of a template we'll use for configuring
the network on these Debian machines. This is only necessary if you want to
manage networking from Ansible rather than manually or via each host in PVE.
You should probably be familiar with Ansible prior to doing this, as your method
may involve setting host variables for the IP addresses for each host, etc.
Let's get that interface template out of the way. Feel free to skip this file
(and leave it undefined in group_vars/pve01
) otherwise. Here's one that I use:
# {{ ansible_managed }}
auto lo
iface lo inet loopback
allow-hotplug enp2s0f0
iface enp2s0f0 inet manual
auto vmbr0
iface vmbr0 inet static
address {{ lookup('dig', ansible_fqdn) }}
gateway 10.4.0.1
netmask 255.255.255.0
bridge_ports enp2s0f0
bridge_stp off
bridge_fd 0
allow-hotplug enp2s0f1
auto enp2s0f1
iface enp2s0f1 inet static
address {{ lookup('dig', ansible_hostname + "-clusternet.local") }}
netmask 255.255.255.0
You might not be familiar with the dig
lookup, but basically here we're doing
an A record lookup for each machine (e.g. lab-node01.local) for the first
interface (and configuring it as a bridge we'll use for VM interfaces), and then
another slightly modified lookup for the "clustering" network we might use for
Ceph ("lab-node01-clusternet.local"). Of course, yours may look completely
different, especially if you're using bonding, three different networks for
management/corosync, storage and VM traffic, etc.
Finally, let's write our playbook. site.yml
will look something like this:
---
- hosts: all
become: True
roles:
- geerlingguy.ntp
# Leave this out if you're not modifying networking through Ansible
- hosts: pve01
become: True
serial: 1
tasks:
- name: Install bridge-utils
apt:
name: bridge-utils
- name: Configure /etc/network/interfaces
template:
src: "{{ interfaces_template }}"
dest: /etc/network/interfaces
register: _configure_interfaces
- block:
- name: Reboot for networking changes
shell: "sleep 5 && shutdown -r now 'Networking changes found, rebooting'"
async: 1
poll: 0
- name: Wait for server to come back online
wait_for_connection:
delay: 15
when: _configure_interfaces is changed
- hosts: pve01
become: True
roles:
- lae.proxmox
Basically, we run the NTP role across all hosts (you might want to add some
non-Proxmox machines), configure networking on pve01
with our separate cluster
network and bridge layout, reboot to make those changes take effect, and then
run this Proxmox role against the hosts to setup a cluster.
At this point, our playbook is ready and we can run the playbook.
Ensure that roles and dependencies are installed:
ansible-galaxy install -r roles/requirements.yml --force
pip install jmespath dnspython
jmespath
is required for some of the tasks involving clustering. dnspython
is only required if you're using a dig
lookup, which you probably won't be if
you skipped configuring networking. We pass --force
to ansible-galaxy
here
so that roles are updated to their latest versions if already installed.
Now run the playbook:
ansible-playbook -i inventory site.yml -e '{"pve_reboot_on_kernel_update": true}'
The -e '{"pve_reboot_on_kernel_update": true}'
should mainly be run the first
time you do the Proxmox cluster setup, as it'll reboot the server to boot into
a PVE kernel. Subsequent runs should leave this out, as you want to sequentially
reboot servers after the cluster is running.
To specify a particular user, use -u root
(replacing root
), and if you need
to provide passwords, use -k
for SSH password and/or -K
for sudo password.
For example:
ansible-playbook -i inventory site.yml -K -u admin1
This will ask for a sudo password, then login to the admin1
user (using public
key auth - add -k
for pw) and run the playbook.
That's it! You should now have a fully deployed Proxmox cluster. You may want to create Ceph storage on it afterwards (see Ceph for more info) and other tasks possibly, but the hard part is mostly complete.
This will configure hosts in the group pve01
as one cluster, as well as
reboot the machines should the kernel have been updated. (Only recommended to
set this flag during installation - reboots during operation should occur
serially during a maintenance period.) It will also enable the IPMI watchdog.

To enable clustering with this role, configure the following variables appropriately:
pve_cluster_enabled: no # Set this to yes to configure hosts to be clustered together
pve_cluster_clustername: "{{ pve_group }}" # Should be set to the name of the PVE cluster
pve_manage_hosts_enabled : yes # Set this to no to NOT configure hosts file (case of using vpn and hosts file is already configured)
The following variables are used to provide networking information to corosync. These are known as ring0_addr/ring1_addr or link0_addr/link1_addr, depending on PVE version. They should be IPv4 or IPv6 addresses. For more information, refer to the Cluster Manager chapter in the PVE Documentation.
# pve_cluster_addr0: "{{ ansible_default_ipv4.address }}"
# pve_cluster_addr1: "another interface's IP address or hostname"
You can set options in the datacenter.cfg configuration file:
pve_datacenter_cfg:
keyboard: en-us
You can also configure HA manager groups:
pve_cluster_ha_groups: [] # List of HA groups to create in PVE.
This example creates a group "lab_node01" for resources assigned to the lab-node01 host:
pve_cluster_ha_groups:
- name: lab_node01
comment: "My HA group"
nodes: "lab-node01"
nofailback: 0
restricted: 0
All configuration options supported in the datacenter.cfg file are documented in the Proxmox manual datacenter.cfg section.
In order for live reloading of network interfaces to work via the PVE web UI,
you need to install the ifupdown2
package. Note that this will remove
ifupdown
. You can specify this using the pve_extra_packages
role variable.
This role does not install NTP, so you should configure NTP yourself, e.g. with
the geerlingguy.ntp
role as shown in the example playbook.
When clustering is enabled, this role makes use of the json_query
filter,
which requires that the jmespath
library be installed on your control host.
You can either pip install jmespath
or install it via your distribution's
package manager, e.g. apt-get install python-jmespath
.
You can use this role to manage users and groups within Proxmox VE (both in single server deployments and cluster deployments). Here are some examples.
pve_groups:
- name: Admins
comment: Administrators of this PVE cluster

This section could use a little more love. If you are actively using this role to manage your PVE Ceph cluster, please feel free to flesh this section more thoroughly and open a pull request! See issue #68.
PVE Ceph management with this role is experimental. While users have successfully used this role to deploy PVE Ceph, it is not fully tested in CI (due to a lack of usable block devices to use as OSDs in Travis CI). Please deploy a test environment with your configuration first prior to prod, and report any issues if you run into any.
This role can configure the Ceph storage system on your Proxmox hosts. The following definitions show some of the configurations that are possible.

pve_ceph_network
by default uses the ipaddr
filter, which requires the
netaddr
library to be installed and usable by your Ansible controller.
pve_ceph_nodes
by default uses pve_group
, this parameter allows to specify on which nodes install Ceph (e.g. if you don't want to install Ceph on all your nodes).
pve_ceph_osds
by default creates unencrypted ceph volumes. To use encrypted volumes the parameter encrypted
has to be set per drive to true
