How-to guides
=============

These guides provide instructions for using Ubuntu images on Oracle Cloud. They help you do things like deploy virtual machines, enable security features, and perform upgrades.


Using Ubuntu images on Oracle Cloud
-----------------------------------
You can use Ubuntu images on Oracle Cloud to deploy virtual machines (VMs) or Oracle Kubernetes Engine (OKE) nodes.

* :doc:`Find Ubuntu images <find-ubuntu-images>`
* :doc:`Deploy Ubuntu OKE nodes using CLI <deploy-ubuntu-oke-nodes-using-cli>`
* :doc:`Deploy Ubuntu OKE nodes using Terraform <deploy-ubuntu-oke-nodes-using-terraform>`

Enabling security features
--------------------------
Enable security features such as full-disk encryption and confidential computing, or use a bastion to access your VM.

* :doc:`use-fde`
* :doc:`enable-confidential-computing`
* :doc:`Use a bastion for access <use-bastion-to-access-VM>`


Performing upgrades
-------------------
Upgrade from one LTS version of Ubuntu to another.

* :doc:`upgrade-from-focal-to-jammy`
* :doc:`upgrade-from-jammy-to-noble`
