Install debian package using cloud-init

Question

I'm trying to install netcat using cloud-init.

As soon as I SSH'd to my vm, with all my keys configured correctly via cloud-init (meaning, it's executing), I try to run netcat and it doesn't work;

I'm using Container-Optimized OS (cos) as they refer to use it for cloud-init, and as of research I found cos is based on ChromiumOS kernel;

All I add to my cloud-init file is

packages:
 - nano
 - netcat

And none of them work.

Is there anything I'm missing to be able to add these packages?

Answer 1

Assuming you want to run tools like nano and netcat interactively in that session, you can use the CoreOS toolbox in Container-Optimized OS to install and run these tools.

$ toolbox apt-get install -y nano netcat
$ toolbox nano
