+# CentOS 9 Stream Packer Template for MAAS
+
+## Introduction
+
+The Packer template in this directory creates a CentOS 9 Stream AMD64 image for use
+with MAAS.
+
+## Prerequisites (to create the image)
+
+* A machine running Ubuntu 22.04 with the ability to run KVM virtual machines.
+* qemu-utils, libnbd-bin, nbdkit and fuse2fs
+* [Packer.](https://www.packer.io/intro/getting-started/install.html), v1.7.0 or newer
+
+## Requirements (to deploy the image)
+
+* [MAAS](https://maas.io) 3.0, [MAAS](https://maas.io) 3.2 recommended
+* [Curtin](https://launchpad.net/curtin) 21+
+
+## Default user
+
+The default username is cloud-user
+
+## Customizing the Image
+
+The deployment image may be customized by modifying http/centos9-stream.ks. See the [CentOS kickstart documentation](https://docs.centos.org/en-US/centos/install-guide/Kickstart2/) for more information.
+
+## Building the image using a proxy
+
+The Packer template downloads the CentOS net installer from the Internet. To
+tell Packer to use a proxy set the HTTP_PROXY environment variable to your proxy
+server. Alternatively you may redefine iso_url to a local file.
+
+To use a proxy during the installation define the `KS_PROXY` variable in the
+environment, as bellow:
+
+```shell
+export KS_PROXY="--proxy=\"${HTTP_PROXY}\""
+```
+
+## Building an image
+
+You can easily build the image using the Makefile:
+
+```shell
+make
+```
+
+Alternatively you can manually run packer. Your current working directory must
+be in packer-maas/centos9-stream, where this file is located. Once in
+packer-maas/centos9-stream you can generate an image with:
+
+```shell
+packer init
+PACKER_LOG=1 packer build .
+```
+
+Note: centos9-stream.pkr.hcl is configured to run Packer in headless mode. Only Packer
+output will be seen. If you wish to see the installation output connect to the
+VNC port given in the Packer output or change the value of headless to false in
+centos9-stream.pkr.hcl.
+
+Installation is non-interactive.
+
+## Uploading an image to MAAS
+
+```shell
+maas $PROFILE boot-resources create \
+    name='custom/9-stream-custom' title='CentOS 9 Stream Custom' \
+    architecture='amd64/generic' filetype='tgz' base_image='rhel/9' \
+    content@=centos9-stream.tar.gz
+```
+
+## Default Username
+
+The default username is ```cloud-user```
