The Go envd guest agent (`envd/`) is fully replaced by the Rust
implementation (`envd-rs/`). This commit removes the Go module and
updates all references across the codebase.
Makefile: remove ENVD_DIR, VERSION_ENVD, build-envd-go, dev-envd-go,
and Go envd from proto/fmt/vet/tidy/clean targets. Add static-link
verification to build-envd.
Host agent: rewrite snapshot quiesce comments that referenced Go GC
and page allocator corruption — no longer applicable with Rust envd.
Tighten envdclient to expect HTTP 200 (not 204) from health and file
upload endpoints, and require JSON version response from FetchVersion.
Remove NOTICE (no e2b-derived code remains). Update CLAUDE.md and
README.md to reflect Rust envd architecture.
Moves 12 packages from internal/ to pkg/ (config, id, validate, events, db,
auth, lifecycle, scheduler, channels, audit, service) so they can be imported
by the enterprise repo as a Go module dependency.
Introduces pkg/cpextension (shared Extension interface + ServerContext) and
pkg/cpserver (Run() entrypoint with functional options) so the enterprise
main.go can call cpserver.Run(cpserver.WithExtensions(...)) without duplicating
the 20-step server bootstrap. Adds db/migrations/embed.go for go:embed access
to OSS SQL migrations from the enterprise module.
cmd/control-plane/main.go is reduced to a 10-line wrapper around cpserver.Run.
healthchecks
Fix ENV instructions to expand $VAR references at set time using the
current env state, preventing self-referencing values like
PATH=/opt/venv/bin:$PATH from producing recursive expansions. Remove
expandEnv from shellPrefix to avoid double expansion.
Fetch sandbox environment variables via `env` before recipe execution
so ENV steps resolve against actual runtime values from the base
template image.
Replace hardcoded healthcheck timing with a Dockerfile-like flag parser
supporting --interval, --timeout, --start-period, and --retries. Add
start-period grace window and bounded retry counting to
waitForHealthcheck.
Add python-interpreter-v0-beta recipe and healthcheck files.
Add Caddy to docker-compose as the single entry point on port 8000:
- localhost -> /api/* stripped and proxied to CP:8080, /* to frontend:5173
- *.localhost -> proxied to CP:8080 (sandbox proxy catch-all)
- Direct /v1/*, /auth/*, /docs routes proxied to CP
Move CP from :8000 to :8080 (its default). Caddy takes :8000.
Update .env.example, vite proxy target (kept as fallback), and Makefile
dev targets (pg_isready via docker exec, frontend binds 0.0.0.0).
This is an intermediate state — needs further work for the full code
interpreter feature.
- REST API (chi router): sandbox CRUD, exec, pause/resume, file write/read
- PostgreSQL persistence via pgx/v5 + sqlc (sandboxes table with goose migration)
- Connect RPC client to host agent for all VM operations
- Reconciler syncs host agent state with DB every 30s (detects TTL-reaped sandboxes)
- OpenAPI 3.1 spec served at /openapi.yaml, Swagger UI at /docs
- Added WriteFile/ReadFile RPCs to hostagent proto and implementations
- File upload via multipart form, download via JSON body POST
- sandbox_id propagated from control plane to host agent on create
Implement the host agent as a Connect RPC server that orchestrates
sandbox creation, destruction, pause/resume, and command execution.
Includes sandbox manager with TTL-based reaper, network slot allocator,
rootfs cloning, hostagent proto definition with generated stubs, and
test/debug scripts. Fix Firecracker process lifetime bug where VM was
tied to HTTP request context instead of background context.
Implements Phase 1: boot a Firecracker microVM, execute a command inside
it via envd, and get the output back. Uses raw Firecracker HTTP API via
Unix socket (not the Go SDK) for full control over the VM lifecycle.
- internal/vm: VM manager with create/pause/resume/destroy, Firecracker
HTTP client, process launcher with unshare + ip netns exec isolation
- internal/network: per-sandbox network namespace with veth pair, TAP
device, NAT rules, and IP forwarding
- internal/envdclient: Connect RPC client for envd process/filesystem
services with health check retry
- cmd/host-agent: demo binary that boots a VM, runs "echo hello", prints
output, and cleans up
- proto/envd: canonical proto files with buf + protoc-gen-connect-go
code generation
- images/wrenn-init.sh: minimal PID 1 init script for guest VMs
- CLAUDE.md: updated architecture to reflect TAP networking (not vsock)
and Firecracker HTTP API (not Go SDK)
