INSTALLING PACKAGES IN PROXMOX 8 IN BULK
This is a Christmas gift for all those Proxmox enthusiasts or those who are recently getting to know it because it is the best alternative after VMware was purchased by Broadcom. We have been a Proxmox partner for many years and we encourage you to take the step if you have not done so yet.
With this script you can install the packages you need in your cluster or on independent nodes as long as they have the same password without having to go node by node.
The operation is simple, on our machine or machine where we run the script we need 3 things:
Install sshpass
apt-get install sshpass
A text file with the name and IP of the nodes one by line
PVE1 192.168.1.250
PVE2 192.168.1.251
PVE3 192.168.1.252
A text file with the packages to install, one per line
telnet
net-tools
With this we create our install-packets.sh script by pasting the following code:
#!/bin/bash
# Files
while true; do
read -p "Enter the path to the hosts file: " NODES_FILE
if [[ -f "$NODES_FILE" ]]; then
echo "Hosts file found: $NODES_FILE"
break
else
echo "Error: The file does not exist at the specified path. Please enter a valid path."
fi
done
while true; do
read -p "Enter the path to the package file: " PACKAGES_FILE
if [[ -f "$PACKAGES_FILE" ]]; then
echo "Package file found: $PACKAGES_FILE"
break
else
echo "Error: The file does not exist at the specified path. Please enter a valid path."
fi
done

echo "1) Enterprise"
echo "2) No-Subscription"

# Repositories CEPH
echo "Which version of Ceph do you want to use?"
echo "1) Ceph Reef"

# Wait for all background processes to finish
wait
echo "Completion of the process."
We give it permissions with chmod +x install-packets.sh and run it ./install-packets.sh obtaining the following output
It is a very versatile script that you can adapt to other versions of Proxmox or other systems.
Test it in a lab first to understand how it works.
Happy holidays.
FAQS
Proxmox is free and open source, but offers four types of subscription (Community, Basic, Standard and Premium) for access to stable repositories and official technical support. Without a subscription you have everything Proxmox offers, there is no limitation and you can use the “no-subscription” or “test” repositories.
If you don’t have a subscription, you can switch your repositories to use the “no-subscription” channel. You can do this from the Proxmox web interface or via the console as on any Debian system.
It is not recommended for production environments, but we can use 2 nodes by adding a qdevice that can even be on a raspberry.
A QDevice (Quorum Device) is a witness installed on a virtual machine or physical device that is used in a Proxmox VE cluster to help avoid quorum issues when you have only two nodes. It is necessary to install corosync-qnetd on the device and on all two nodes in the cluster. Once installed from any node we run pvecm qdevice ip_qdevice.
