Notes from a NixOps beginner

by Matan Shenhav (ixxie - m.shenhav@gmail.com)

2020/07/01 - while work towards NixOps 2.0 is being committed to master

First impressions

I first looked into NixOps a few years ago, and only very briefly. Trying to get back into it again now, there are some logistical obstacles.

I'm trying to get a toy D3 Svelte component going to explore integration strategies between the two. I'm trying to leverage Svelte bindings and D3 scales to let the chart rescale to the viewport; it seems to break the chart:

Github Action works in its own repo but not from another repo

I'm having trouble with a remote call of a github action. The issue concerns an action I created called nixosify which is designed to install my Linux distro of choice on a remote machine. The action accepts four parameters:

target: ip of the machine to convert
tempkey: private key to grant access to the target
tempkey_pub: the temporary public key, used to add to the install medium
authkey_pub: a permanent public key to add to authorized keys on the target, post install

As you can see in this successful execution of a test workflow this all seems good and well. The test workflow uses a VPS provider's CLI to create an test instance, run the test, and kill it.

hello folks; I'm working on some github CI/CD pipelines, and getting stomped with some ssh issues. I made a github action called nixosify which is an script which sshes into a VM and install a distribution on it. The nixosify repo has a test (shared in the gist) which works fine, but when I call this in a pipeline for deploying a server in another repo I am working on called mindcraft, I get ssh errors, and I cannot for the life of me figure out why the same code gives an error in one context but not the other.

I already recreated the ssh keys to ensure I didn't make a mistake there but I am having no luck here. In both cases I create the VM using the VPS provider's CLI and reference a public ssh key that I added to my account.
