Workspace version goes from 1.8.1 → 1.9.0. Internal crate deps that
carry an explicit version (wfe-buildkit-protos, wfe-containerd-protos,
wfe in wfe-deno) are bumped to match.
CHANGELOG.md documents the release under `## [1.9.0] - 2026-04-07`:
* wfectl CLI with 17 subcommands
* wfectl validate (local YAML compile, no round-trip)
* Human-friendly workflow names (instance sequencing + definition
display name)
* wfe-server full feature set (kubernetes + deno + buildkit +
containerd + rustlang) on a debian base
* wfe-ci builder Dockerfile
* /bin/bash for run scripts
* ensure_store_exists called on host start
* SubWorkflowStep parent data inheritance
* workflows.yaml restructured for YAML 1.1 shallow-merge semantics
Pure formatting pass from `cargo fmt --all`. No logic changes. Separating
this out so the 1.9 release feature commits that follow show only their
intentional edits.
- tonic-reflection for gRPC service discovery
- /schema/workflow.json (JSON Schema from schemars derives)
- /schema/workflow.yaml (same schema in YAML)
- /schema/workflow.proto (raw proto file)
- Multi-stage alpine Dockerfile with all executor features
- Comprehensive configuration reference (wfe-server/README.md)
- Release script (scripts/release.sh)
- Bumped to 1.8.1
Add wfe-server-protos and wfe-server to workspace members.
Update StepExecutionContext constructions with log_sink: None
in buildkit and containerd test files.
Replaced third-party buildkit-client git dependency with
wfe-buildkit-protos generated from official moby/buildkit protos.
Direct ControlClient gRPC calls: SolveRequest with frontend attrs,
exporters, cache options. Daemon-local context paths for builds
(session protocol for remote transfer is TODO).
Both proto crates now use tonic 0.14 / prost 0.14 — no transitive
dependency conflicts. 95 combined tests, 85.6% region coverage.
Replaced buildctl CLI shell-out with direct gRPC communication via
buildkit-client crate. Connects to buildkitd daemon over Unix socket
or TCP with optional TLS.
Implementation:
- connect() with custom tonic UnixStream connector
- execute_build() implementing the solve protocol directly against
ControlClient (session setup, file sync, frontend attributes)
- Extracts digest from containerimage.digest in solve response
Added custom lima template (test/lima/wfe-test.yaml) that provides
both buildkitd and containerd with host-forwarded Unix sockets for
reproducible integration testing.
E2E tests against real buildkitd daemon via WFE_BUILDKIT_ADDR env var.
54 tests total. 89% line coverage (cargo-llvm-cov with E2E).
Standalone workspace crates for BuildKit image building and containerd
container execution. Config types, YAML schema integration, compiler
dispatch, validation rules, and mock-based unit tests.
Current implementation shells out to buildctl/nerdctl — will be
replaced with proper gRPC clients (buildkit-client, containerd protos)
in a follow-up. Config types, YAML integration, and test infrastructure
are stable and reusable.
wfe-buildkit: 60 tests, 97.9% library coverage
wfe-containerd: 61 tests, 97.8% library coverage
447 total workspace tests.
