Hey everyone! I'm starting a three-week internship in two weeks and I'm excited but also a bit anxious about my project. I have around 6-7 months of experience with Linux, but very little with automation.
Here's the deal: when I install an Ubuntu image on a device, I need to connect it to a server using cloud-init to retrieve pre-installed software and configurations (though I'm still waiting on specifics). Importantly, this setup needs to be independent of any specific Ubuntu version.
Given my limited experience and the tight timeline, do you think I can manage this? I'm planning to dig into cloud-init and Ubuntu's quick start guide soon. Any tips or insights would be much appreciated!

It’s tough to give advice without knowing your exact requirements. Are your servers meant to run for a long time or are they short-lived instances? If they're meant to keep a specific state, then consider using a configuration tool like Ansible. If they're just temporary, cloud-init might suffice.
Cloud-init is great for standard tasks like setting up user accounts, SSH keys, and installing packages. However, if your configuration needs get more intricate, you might want to check out a proper configuration management system like Ansible to handle the heavy lifting. Just something to keep in mind depending on the complexity of your project!
Thanks for that! I'll definitely look into the modules. Just trying to gauge how far I can push it with my current skills!
I’d suggest a combination of cloud-init and Ansible if your task isn’t too complicated. They both utilize YAML and can work well together. Use cloud-init to set up an Ansible service user, install some essential packages, and configure networking, then let Ansible handle the rest of the configuration to meet your standards.
You should definitely use cloud-init for your initial setup, but you might need to manage more complex stuff afterward. It really depends on your specific requirements. Some folks utilize shell scripts alongside it, others prefer config management tools like Ansible since they’re easier to learn and set up.
I see your point, but I think cloud-init is really powerful with all its modules. Definitely check out the module documentation; it can handle lots of tasks during initial boot, like disk setup and more!
