Reminded me of how to install Alpine linux (which isn't available) on Oracle cloud over an ubuntu install. It uses dd and has the advantage of having a console.

Reminded me of how to install Alpine linux (which isn't available) on Oracle cloud over an ubuntu install. It uses dd and has the advantage of having a console. I had found it in a github gist when I used it but here's a similar blog post. https://alextsang.net/articles/20191006-063049/index.html https://alextsang.net/articles/20191006-063049/index.html

Wait hold on, can you not simply just access the underlying volume/block device using an API? The VMs in OCI have a boot volume that is attached, so I reckon it's possible to "mount" this somehow and overwrite it with whatever data you want.

  I am not sure. Maybe it's a thing about not being able to download the iso (no network on the console?) or not having space for it or something. I wouldn't know about the API thing. I am not a cloud user. Made me think though.

From what it sounds like, because you have a console and therefore aren't dependent on SSHD not getting overwritten, you can just dd the live running system here?

  Like I said in the other comment I am not really familiar with the various clouds. I self host. The console is a weird web based thing that isn't the same environment as your VMs (or their hypervisor). It's a barebones shell where you can mount your volumes and such, not actually boot or enter the vm. (Edit: This was incorrect) And if I remember correctly I probably did have to do some mounting there to create device files and such. I didn't really have much use for the console after that either. I will try to find the actual gist I followed. Here's the gist I had used. It's really simple. https://gist.github.com/unixfox/05d661094e646947c4b303f19f9bae11 https://gist.github.com/unixfox/05d661094e646947c4b303f19f9b... Why would not have not done the dd bit on the console? I have no idea. Again possibly can't download the iso there?
