Adding behavior to a resource
What's the recommended way to add behavior to resources that already have a driver? For example, we have some additional interface configuration steps we need to take on some Cisco router interfaces. I looked at the Shell Developer Guide, but it's all about creating a new driver for resources that don't already have one.
It seems my options are:
- Do it all from the environment driver. It doesn't seem like a good idea to try to run a series of SSH commands from here though.
- Add behavior to the existing resource driver. Clone the existing repo, and add our code in a new private branch.
- Subclass the existing resource driver. It's not clear if this is possible, or how it might be done, though that may be my Python inexperience showing.
- Create a new resource driver that wraps the existing one.
Any comments and suggestions are greatly appreciated.
(Note that we're still on 7.1, but I'm interested in how we could do this with 7.1 or 8.0 and the gen 2 shells.)
Hi Jim,
It really depends on what you want to achieve.
If you just want to add another set of commands to a resource and those doesn't require you to use our python packages you can just add them as a python script and attach to the resource those commands will be exposed in the interface and can be called from the orchestration.
If you do need to use our existing packages (without modifying them) for some functionality then i would go with Cloning the repo and add your code on there (if you think this is something that can benefits other feel free to contribute it back as a pull request).
If you also need to change something in the core packages that's another story.
Hope this helps
Thanks @Dan.M I hadn't considered using an external script; I don't think it's right for this situation, but it's worth keeping in mind for the future. I think for my first time doing this, I'm going to clone and add to the resource driver. I'd like to eventually come back and follow the Quali convention of using Runners and Flows, but that means either updating the `cloudshell-networking-cisco` package or making a new one.
I hope people will vote on my related idea to simplify this process.
