This pull request introduces support for external workspace management, allowing users to register and manage workspaces that are provisioned and managed outside of the Coder.
* Added has_external_agent field to workspace builds and template versions
## Description
This PR ensures that prebuilt workspaces are properly excluded from the
lifecycle executor and treated as a separate class of workspaces, fully
managed by the prebuild reconciliation loop.
It introduces two lifecycle guarantees:
* When a prebuilt workspace is created (i.e., when the workspace build
completes), all lifecycle-related fields are unset, ensuring the
workspace does not participate in TTL, autostop, autostart, dormancy, or
auto-deletion logic.
* When a prebuilt workspace is claimed, it transitions into a regular
user workspace. At this point, all lifecycle fields are correctly
populated according to template-level configurations, allowing the
workspace to be managed by the lifecycle executor as expected.
## Changes
* Prebuilt workspaces now have all lifecycle-relevant fields unset
during creation
* When a prebuild is claimed:
* Lifecycle fields are set based on template and workspace level
configurations. This ensures a clean transition into the standard
workspace lifecycle flow.
* Updated lifecycle-related SQL update queries to explicitly exclude
prebuilt workspaces.

To reduce the scope of this PR and make the review process more
manageable, the original implementation has been split into the
following focused PRs:
* https://github.com/coder/coder/pull/19259
* https://github.com/coder/coder/pull/19263
* https://github.com/coder/coder/pull/19264
* https://github.com/coder/coder/pull/19265
These PRs should be considered in conjunction with this one to
understand the complete set of lifecycle separation changes for prebuilt
workspaces.
This is a workaround for https://github.com/coder/coder/issues/18776
We avoid the foreign key issue by checking the previously inserted
workspace applications before calling UpdateWorkspaceAITask. Now,
affected workspaces will show as "not running an AI task" on the single
task view, which is technically correct.
We also insert a provisioner job log at WARN level to ensure that the
user sees some information that they have run into this issue, as well
as logging on the server side.
Longer term, we plan to modify how the workspace tasks view is
presented. This is a stopgap measure until we solidify that plan.
NOTE: this does **not** address the fact that stopping a workspace with
`has_ai_task: true` will result in the completed stop build no longer
having `has_ai_task: true`, resulting in tasks "disappearing" on stop.
- Adds/improves a lot of comments to make the autostop calculation code
clearer
- Changes the behavior of the enterprise template schedule store to
match the behavior of the workspace TTL endpoint when the new TTL is
zero
- Fixes a bug in the workspace TTL endpoint where it could unset the
build deadline, even though a max_deadline was specified
- Adds a new constraint to the workspace_builds table that enforces the
deadline is non-zero and below the max_deadline if it is set
- Adds CHECK constraint enum generation to scripts/dbgen, used for
testing the above constraint
- Adds Dean and Danielle as CODEOWNERS for the autostop calculation code
This PR sets a constraint of 1MB on the provisioner job logs written to
the database. This is consistent with the constraint we place on
workspace agent logs:
https://github.com/coder/coder/blob/4ac6be6d835dc36c242e35a26b584b784040bf28/coderd/database/dump.sql#L2030
It also adds a message printed to the front end about the provisioner
log overflow, and updates the message printed to the front end when
workspace startup logs exceed the max, as it was causing some customers
to think their startup script had failed to run.
## Description
This PR adds support for `description` and `icon` fields to
`template_version_presets`. These fields will allow displaying richer
information for presets in the UI, improving the user experience when
creating a workspace.
Both fields are optional, non-nullable, and default to empty strings.
## Changes
* Database migration with the addition of `description VARCHAR(128)` and
`icon VARCHAR(256)` columns to the `template_version_presets` table.
* Updated the `CreateWorkspacePageView` in the UI
Note: UI changes will be addressed in a separate PR

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.

This PR implements protobuf streaming to handle large module files by:
1. **Streaming large payloads**: When module files exceed the 4MB limit,
they're streamed in chunks using a new UploadFile RPC method
2. **Database storage**: Streamed files are stored in the database and
referenced by hash for deduplication
3. **Backward compatibility**: Small module files continue using the
existing direct payload method

Ensures that no workspace build timings with zero values for started_at or ended_at are inserted into the DB or returned from the API.
## 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

This PR refactors the CompleteJob function to use database transactions
more consistently for better atomicity guarantees. The large function
was broken down into three specialized handlers:
- completeTemplateImportJob
- completeWorkspaceBuildJob
- completeTemplateDryRunJob
Each handler now uses the Database.InTx wrapper to ensure all database
operations for a job completion are performed within a single
transaction, preventing partial updates in case of failures.
Added comprehensive tests for transaction behavior for each job type.

Closes https://github.com/coder/internal/issues/369
We can't know whether a replacement (i.e. drift of terraform state
leading to a resource needing to be deleted/recreated) will take place
apriori; we can only detect it at `plan` time, because the provider
decides whether a resource must be replaced and it cannot be inferred
through static analysis of the template.
**This is likely to be the most common gotcha with using prebuilds,
since it requires a slight template modification to use prebuilds
effectively**, so let's head this off before it's an issue for
customers.
Drift details will now be logged in the workspace build logs:

Plus a notification will be sent to template admins when this situation
arises:

A new metric - `coderd_prebuilt_workspaces_resource_replacements_total`
- will also increment each time a workspace encounters replacements.
We only track _that_ a resource replacement occurred, not how many. Just
one is enough to ruin a prebuild, but we can't know apriori which
replacement would cause this.
For example, say we have 2 replacements: a `docker_container` and a
`null_resource`; we don't know which one might
cause an issue (or indeed if either would), so we just track the
replacement.

This pull request allows coder workspace agents to be reinitialized when
a prebuilt workspace is claimed by a user. This facilitates the transfer
of ownership between the anonymous prebuilds system user and the new
owner of the workspace.
Only a single agent per prebuilt workspace is supported for now, but
plumbing has already been done to facilitate the seamless transition to
multi-agent support.

This change adds support for devcontainer autostart in workspaces. The
preconditions for utilizing this feature are:
1. The `coder_devcontainer` resource must be defined in Terraform
2. By the time the startup scripts have completed,
- The `@devcontainers/cli` tool must be installed
- The given workspace folder must contain a devcontainer configuration
Example Terraform:
```tf
resource "coder_devcontainer" "coder" {
agent_id = coder_agent.main.id
workspace_folder = "/home/coder/coder"
config_path = ".devcontainer/devcontainer.json" # (optional)
}
```

In the presence of multiple devcontainers, it would be nice to
differentiate them by name. This change inherits the resource name from
terraform.
Refs #17076
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.
