2024-03-26 r/7782 feat(ops/terraform/deploy-nixos): add `build` parameterFlorian Klink1-1/+10
If this is set to true (and only then), also invoke `nix-build` on the previously-instantiated .drv to cause builds/substitutions on the local machine. There's no terraform example for this in here, but this is useful if you want to perform builds locally, for example to upload nix-built blobs elsewhere through terraform.

We already did all the instantiation, grabbing the calculated output path too is cheap. Change-Id: Id591865c65159409da739f706a9de29a9f50456a Reviewed-on: https://cl.tvl.fyi/c/depot/+/11214 Reviewed-by: tazjin <tazjin@tvl.su> Tested-by: BuildkiteCI Autosubmit: flokli <flokli@flokli.de>
2024-03-22 r/7760 docs(ops/terraform/deploy-nixos): document inputs and outputsFlorian Klink3-22/+35
This documents the input and output format, and also removes some references to Terraform and evaluating NixOS system configurations. It can be used to evaluate anything.

2024-03-14 r/7690 feat(ops/terraform/deploy-nixos): support argstr mapFlorian Klink1-3/+3
This allows setting argstr to a map of keys and values. We use jq to construct "--argstr k v" arguments, which are passed to nix-instantiate.

2023-05-16 r/6143 feat(ops/terraform/deploy-nixos): make target_user_ssh_key optionalFlorian Klink2-9/+14
In case `target_user_ssh_key` points to an empty string, nixos-copy.sh just doesn't set `IdentityFile=` at all. This allows using deploy-nixos without any explicitly passed ssh keys, but picking up whatever ssh setup the user has configured locally.

2023-03-03 r/5872 feat(ops/terraform): add trigger to deploy-nixos, remove target_nameFlorian Klink2-10/+8
This allows passing in custom triggers to trigger a (re)deploy. For example, a caller can put an AWS instance ID into the triggers to cause a redeploy whenever the instance ID has changed. The `target_name` terraform variable was doing something similar, but `triggers` is more generic, allowing multiple triggers, without having to stringify them. We also don't need to trigger on the attrpath - it can be changed, and as long as it still evaluates to the same `data.external.nixos_system.result.drv` (which is checked on every plan), no redeploy needs to be made.

2023-03-03 r/5871 feat(ops/terraform): allow specifying an entrypoint for the attrsetFlorian Klink2-5/+15
This adds an additional parameter `entrypoint`, pointing to a .nix file (or a directory containing a `default.nix` file) that's providing the attribute path asked for. If not set / kept at the default (empty string), it falls back to the root dir of the repository as before.

2023-03-03 r/5867 feat(ops/terraform): add module for deploying NixOS system closuresVincent Ambo5-0/+187
This module makes it fairly easy to deploy NixOS system closures using Terraform, while properly separating the evaluation of a derivation (to determine whether a deploy is needed) from the building and copying of the closure itself. This has been on my stack for a while. It was originally developed for Resoptima, who agreed to open-sourcing it in depot back when we completed our work with them. Their contribution has been acknowledged in the README.
