508d67ad49 refactor(ops/terraform/deploy-nixos): argstr -> argstr_json
At least terraform wants all parameters passed via JSON to be strings.
It can't accept maps.

This means, allowing to pass a `argstr` JSON dict isn't really possible.

However, terraform is perfectly able to JSON-encode a map. So accept a
`argstr_json` argument instead, which `jq` will JSON-decode before
further processing it.

I dropped `argstr` support again so the jq expression still fits on my
screen, if anyone else (started) using this, I'm happy to review a CL
adding this. We should probably move the jq expression to some multiline
format then, though.

f055c75bc0 feat(ops/terraform/deploy-nixos): add build parameter
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.

3281fb9132 docs(ops/terraform/deploy-nixos): document inputs and outputs
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.

35f636b684 feat(ops/terraform/deploy-nixos): support argstr map
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.

14a8ea9eab feat(ops/terraform/deploy-nixos): make target_user_ssh_key optional
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.

774194652b feat(ops/terraform): add trigger to deploy-nixos, remove target_name
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.

c3750079f7 feat(ops/terraform): allow specifying an entrypoint for the attrset
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.

dbca46d052 feat(ops/terraform): add module for deploying NixOS system closures
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.
