Hello OpenNebula Team! I want to create an appliance based on the Ubuntu 22.04 distro in order to upload it to a common OpenNebula marketplace with the other partners of the project. This appliance will include a service installed via a process of six commands. I have watched the OpenNebula webinar: “Introducing one-apps project, an OpenNebula appliance building tool,” and I have some questions. To create this appliance, should I follow the approach demonstrated with the MariaDB service, or is there a different approach I should take? Specifically, I am aiming to create an Ubuntu Image appliance with a service installed, rather than a service appliance. If I modify `one-apps/packer/ubuntu.10-upgrade-distro.sh` to include the commands needed to install my service, will that work? Should I follow the same approach shown in the webinar? Thank you for your time! ---

In general, the approach followed on the webinar is the “ideal” scenario for a bash based approach. What you could really change is using the ruby framework (more modern one, there is a note about that in the webinar) instead of the bash one. > I am aiming to create an Ubuntu Image appliance with a service installed, rather than a service appliance.

Should I follow the same approach shown in the webinar? You can place your logic wherever you want, but if the intention is to create a custom appliance, it would be ideal to have a dedicated script for it and referencing it within the packer code. That script is used in the base ubuntu distro building. ---

Hello Daniel, thanks for the response! Yes, actually my intention is to create a custom appliance based on the Ubuntu distro. So, 1. If I clone the one-apps repo and create a new script in the one-apps/packer/ubuntu directory with the logic of the appliance that I want to have 2. Then execute this script through the one-apps/packer/ubuntu/80-install-content.sh script 3. And finally execute `make ubuntu` (in order to build it) Is this approach going to work? ---

Yes it will work, however - **ubuntu** is not a good name for a custom app, it could be confusing as there is already ubuntu flavours. But is not a big deal as long as users are aware. - you want to execute the script through another script. This means you’d need to modify said script which is stock OpenNebula script. - If for some reason we change that context install script, then you’ll need to maintain the change sync. - Why not simply add another script with a numbered order ? Packer will call it sequentially. ---

So, if I create a script in `one-apps/packer/ubuntu/99-add-logic.sh` with the logic of the appliance that I want to create, will it be called automatically? Yes, I agree that the name “ubuntu” is not a good name for a custom appliance. If I change the variable `appliance.name` in `one-apps/packer/ubuntu/variables.pkr.hcl`, will it work? ---

Please check [this PR](https://github.com/OpenNebula/one-apps/pull/76) for the code example showcased in the webinar. The script will be called due to how [packer references them](https://github.com/OpenNebula/one-apps/blob/7921e5c9b22ab86d8118f62f02af8116fee9e90a/packer/ubuntu/ubuntu.pkr.hcl#L58-L67).
