# Packer MAAS



[Packer](http://packer.io) [templates](https://www.packer.io/docs/templates/index.html),

associated scripts, and configuration for creating deployable OS images for [MAAS](http://maas.io).



See README.md in each directory for documentation on how to customize, build,

and upload images.



Read more about how [custom images](https://maas.io/docs/how-to-customise-images) work.

### Maturity level



* Templates marked as *EOL* are OSes that are no longer supported by the upstream maintainer, and **are not recommended for new deployments**. These systems don't receive security updates and mirrors can become permanently offline at any moment.

* *Alpha* templates require packages that are not yet generally available, e.g. an unreleased MAAS or Curtin version. These should not be used in production environments.

* *Beta* templates should work but we still don't have enough successful deployment reports to regard it as *Stable*.



### Output



All templates are configured to output to serial. Packer does not officially

support serial output([GH:5](https://github.com/hashicorp/packer-plugin-qemu/issues/5)).

To see output run with PACKER_LOG=1.



If you wish to use a GUI modify each template as follows:



* Remove any boot_command line that contains "console" or "com1_Port"

* Remove ""-serial", "stdio"" from qemuargs. qemuargs may be removed as well if empty.



If you wish to use QEMU's UI also remove "headless": true



If you keep "headless": true you can connect using VNC. Packer will output the

IP and port to connect to when run.



## Contributing new templates



We welcome contributions of new templates.



The following is a set of guidelines for contributing to Packer MAAS. These are mostly guidelines, not rules. Use your best judgment, and feel free to propose changes to this document in a pull request.



### Project structure



Each OS has it's own directory in the repository. The typical contents is:



* one or more HCL2 templates

* a `scripts` directory with auxiliary scripts required by `provisioner` and `post-processor` blocks

* a `http` directory with auto-configuration files used by the OS installer

* a `README.md` file describing

  * what is the target OS

  * host requirements for building this template

  * MAAS requirements for deploying the generated image

  * description of each template (HCL2) file, including the use of all parameters defined by them

  * step by step instruction to build it

  * default login credentials for the image (if any)

  * instructions for uploading this image to MAAS

* a `Makefile` to build the template



### How to submit a new template



1. [Fork the project](https://github.com/canonical/packer-maas/fork) to your own GH account

2. Create a local branch

3. If you are contributing a new OS, create a new directory following the guidelines above

4. If you are creating a new template for an already supported OS, just create a HCL2 file and add auxiliary files it requires to the appropriate directories

5. Run `packer validate .` in the directory to check your template

6. Commit your changes and push the branch to your repository

7. Open a Merge Request to packer-maas

8. Wait for review
