Implement the `coderd` side of the AgentAPI for the upcoming
dev-container agents work.
`agent/agenttest/client.go` is left unimplemented for a future PR
working to implement the agent side of this feature.
Closes https://github.com/coder/internal/issues/648
This change introduces a new `ParentId` field to the agent's manifest.
This will allow an agent to know if it is a child or not, as well as
knowing who the owner is.
This is part of the Dev Container Agents work
This change adds a new `ReportConnection` endpoint to the `agentapi`.
The protocol version was bumped previously, so it has been omitted here.
This allows the agent to report connection events, for example when the
user connects to the workspace via SSH or VS Code.
Updates #15139
As part of the new resources monitoring logic - more specifically for
OOM & OOD Notifications , we need to update the AgentAPI , and the
agents logic.
This PR aims to do it, and more specifically :
We are updating the AgentAPI & TailnetAPI to version 24 to add two new
methods in the AgentAPI :
- One method to fetch the resources monitoring configuration
- One method to push the datapoints for the resources monitoring.
Also, this PR adds a new logic on the agent side, with a routine running
and ticking - fetching the resources usage each time , but also storing
it in a FIFO like queue.
Finally, this PR fixes a problem we had with RBAC logic on the resources
monitoring model, applying the same logic than we have for similar
entities.
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

Bumps the Tailnet and Agent API version 2.3, and creates some extra controls and machinery around these versions.
What happened is that we accidentally shipped two new API features without bumping the version. `ScriptCompleted` on the Agent API in Coder v2.16 and `RefreshResumeToken` on the Tailnet API in Coder v2.15.
Since we can't easily retroactively bump the versions, we'll roll these changes into API version 2.3 along with the new WorkspaceUpdates RPC, which hasn't been released yet. That means there is some ambiguity in Coder v2.15-v2.17 about exactly what methods are supported on the Tailnet and Agent APIs. This isn't great, but hasn't caused us major issues because
1. RefreshResumeToken is considered optional, and clients just log and move on if the RPC isn't supported.
2. Agents basically never get started talking to a Coderd that is older than they are, since the agent binary is normally downloaded from Coderd at workspace start.
Still it's good to get things squared away in terms of versions for SDK users and possible edge cases around client and server versions.
To mitigate against this thing happening again, this PR also:
1. adds a CODEOWNERS for the API proto packages, so I'll review changes
2. defines interface types for different API versions, and has the agent explicitly use a specific version. That way, if you add a new method, and try to use it in the agent without thinking explicitly about versions, it won't compile.
With the protocol controllers stuff, we've sort of already abstracted the Tailnet API such that the interface type strategy won't work, but I'll work on getting the Controller to be version aware, such that it can check the API version it's getting against the controllers it has -- in a later PR.
Closes#14716Closes#14717
Adds a new user-scoped tailnet API endpoint (`api/v2/tailnet`) with a new RPC stream for receiving updates on workspaces owned by a specific user, as defined in #14716.
When a stream is started, the `WorkspaceUpdatesProvider` will begin listening on the user-scoped pubsub events implemented in #14964. When a relevant event type is seen (such as a workspace state transition), the provider will query the DB for all the workspaces (and agents) owned by the user. This gets compared against the result of the previous query to produce a set of workspace updates.
Workspace updates can be requested for any user ID, however only workspaces the authorised user is permitted to `ActionRead` will have their updates streamed.
Opening a tunnel to an agent requires that the user can perform `ActionSSH` against the workspace containing it.
Drops support for v1 of the tailnet API, which was the original coordination protocol where we only sent node updates, never marked them lost or disconnected.
v2 of the tailnet API went GA for CLI clients in Coder 2.8.0, so clients older than that would stop working.
When an agent receives a node, it responds with an ACK which is relayed
to the client. After the client receives the ACK, it's allowed to begin
pinging.
Fixes 2 related issues:
1. wsconncache had incorrect logic to test whether to send DERPMap updates, sending if the maps were equivalent, instead of if they were _not equivalent_.
2. configmaps used a bugged check to test equality between DERPMaps, since it contains a map and the map entries are serialized in random order. Instead, we avoid comparing the protobufs and instead depend on the existing function that compares `tailcfg.DERPMap`. This also has the effect of reducing the number of times we convert to and from protobuf.
fixes#10531
Adds a check for `version` on connection to the Agent API websocket endpoint. This is primarily for future-proofing, so that up-level agents get a sensible error if they connect to a back-level Coderd.
It also refactors the location of the `CurrentVersion` variables, to be part of the `proto` packages, since the versions refer to the APIs defined therein.
Refactors our DRPC service definitions slightly.
In the previous version, I inserted the RPCs from the tailnet proto directly into the Agent service. This makes things hard to deal with because DRPC then generates a new set of methods with new interfaces with the `DRPCAgent_` prefixed. Since you can't have a single method that takes different argument types, we couldn't reuse the implementation of those RFCs without a lot of extra classes and pass-thru methods.
Instead, the "right" way to do it is to integrate at the DRPC layer. So, we have two DRPC services available over the Agent websocket, and register them both on the DRPC `mux`.
Since the tailnet proto RPC service is now for both clients and agents, I renamed some things to clarify and shorten.
This PR also removes the `TailnetAPI` implementation from the `agentapi` package, and the next PR in the stack replaces it with the implementation from the `tailnet` package.
re: #10528
Refactors PG Coordinator to work with the Tailnet v2 API, including wrappers for the existing v1 API.
The debug endpoint functions, but doesn't return sensible data, that will be in another stacked PR.
