Closes https://github.com/coder/internal/issues/312
Depends on https://github.com/coder/terraform-provider-coder/pull/408
This PR adds support for defining an **autoscaling block** for
prebuilds, allowing number of desired instances to scale dynamically
based on a schedule.
Example usage:
```
data "coder_workspace_preset" "us-nix" {
...
prebuilds = {
instances = 0 # default to 0 instances
scheduling = {
timezone = "UTC" # a single timezone is used for simplicity
# Scale to 3 instances during the work week
schedule {
cron = "* 8-18 * * 1-5" # from 8AM–6:59PM, Mon–Fri, UTC
instances = 3 # scale to 3 instances
}
# Scale to 1 instance on Saturdays for urgent support queries
schedule {
cron = "* 8-14 * * 6" # from 8AM–2:59PM, Sat, UTC
instances = 1 # scale to 1 instance
}
}
}
}
```
### Behavior
- Multiple `schedule` blocks per `prebuilds` block are supported.
- If the current time matches any defined autoscaling schedule, the
corresponding number of instances is used.
- If no schedule matches, the **default instance count**
(`prebuilds.instances`) is used as a fallback.
### Why
This feature allows prebuild instance capacity to adapt to predictable
usage patterns, such as:
- Scaling up during business hours or high-demand periods
- Reducing capacity during off-hours to save resources
### Cron specification
The cron specification is interpreted as a **continuous time range.**
For example, the expression:
```
* 9-18 * * 1-5
```
is intended to represent a continuous range from **09:00 to 18:59**,
Monday through Friday.
However, due to minor implementation imprecision, it is currently
interpreted as a range from **08:59:00 to 18:58:59**, Monday through
Friday.
This slight discrepancy arises because the evaluation is based on
whether a specific **point in time** falls within the range, using the
`github.com/coder/coder/v2/coderd/schedule/cron` library, which performs
per-minute matching rather than strict range evaluation.

Updates Terraform from 1.11.4 to 1.12.2 across all relevant files.
Changes include:
- GitHub Actions setup-tf configuration
- Dockerfile configurations (dogfood and base)
- Install script
- Provisioner install.go with version constants
- Test data files (tfstate.json, tfplan.json, version.txt)
Follows the same pattern as PR #17323 which updated to 1.11.4.

## Summary
This PR updates the terraform/testdata by running
`provisioner/terraform/testdata/generate.sh` script. These changes occur
from `terraform-provider-coder`
[v2.4.2](https://github.com/coder/terraform-provider-coder/releases/tag/v2.4.2)
and are associated to the introduction of a `api_key_scope` optional
field with a default value:
https://github.com/coder/terraform-provider-coder/pull/391
## Changes
* Run `provisioner/terraform/testdata/generate.sh` script.
* Update `resource_test.go` to include `api_key_scope`
## Summary
This PR introduces support for expiration policies in prebuilds. The TTL
(time-to-live) is retrieved from the Terraform configuration
([terraform-provider-coder
PR](https://github.com/coder/terraform-provider-coder/pull/404)):
```
prebuilds = {
instances = 2
expiration_policy {
ttl = 86400
}
}
```
**Note**: Since there is no need for precise TTL enforcement down to the
second, in this implementation expired prebuilds are handled in a single
reconciliation cycle: they are deleted, and new instances are created
only if needed to match the desired count.
## Changes
* The outcome of a reconciliation cycle is now expressed as a slice of
reconciliation actions, instead of a single aggregated action.
* Adjusted reconciliation logic to delete expired prebuilds and
guarantee that the number of desired instances is correct.
* Updated relevant data structures and methods to support expiration
policies parameters.
* Added documentation to `Prebuilt workspaces` page
* Update `terraform-provider-coder` to version 2.5.0:
https://github.com/coder/terraform-provider-coder/releases/tag/v2.5.0

Removes `provisioner/terraform/testdata/resources/version.txt`
Pretty sure Claude hallucinated it into existence in #17035 based on the similar `provisioner/terraform/testdata/version.txt`
- Update go.mod to use Go 1.24.1
- Update GitHub Actions setup-go action to use Go 1.24.1
- Fix linting issues with golangci-lint by:
- Updating to golangci-lint v1.57.1 (more compatible with Go 1.24.1)

This change allows specifying devcontainers in terraform and plumbs it
through to the agent via agent manifest.
This will be used for autostarting devcontainers in a workspace.
Depends on coder/terraform-provider-coder#368
Updates #16423
It was hard to deduce whether or not changes in our terraform testdata
are relevant or not, so we now have a rudimentary filter for randomly
generated values that aren't relevant for the testdata.
This pull request adds support for presets to coder provisioners.
If a template defines presets using a compatible version of the
provider, then this PR will allow those presets to be persisted to the
control plane database for use in workspace creation.
As requested for [this
issue](https://github.com/coder/internal/issues/245) we need to have a
new resource `resources_monitoring` in the agent.
It needs to be parsed from the provisioner and inserted into a new db
table.
provisioner/terraform/testdata current version has been generated using
outdated version of terraform-provider - with some parameters that are
not relevant anymore, causing `generate.sh` to fail when trying to
generate new data.
Replace Depot build action with Nix for Nix dogfood image builds
The dogfood Nix image is now built using Nix's native container tooling instead of Depot. This change:
- Adds Nix setup steps to the GitHub Actions workflow
- Removes the Dockerfile.nix in favor of a Nix-native container build
- Updates the flake.nix to support building Docker images
- Introduces a hash file to track Nix-related changes
- Updates the vendorHash for Go dependencies

Terraform changed the default output of the `terraform graph` command. You must put `-type=plan` to keep the prior behavior.
