Pause semantics - PauseBackend now cancels the probe goroutine so no HTTP/TCP/ICMP traffic is sent while the backend is paused. Previously the goroutine kept running and results were silently discarded. - ResumeBackend launches a fresh probe goroutine on the existing worker, preserving transition history. The backend re-enters unknown state. Integration tests (tests/01-maglevd/) - Containerlab topology with 3 nginx:alpine backends on a dedicated management network (172.20.30.0/24) with static IPs. - maglevd config with 200ms HTTP health-check interval for fast test convergence (rise=2, fall=2). - 8 test cases: deploy lab, start maglevd, all backends reach up, nginx logs confirm probes arriving, pause stops probes (probe count stable), resume restarts probes, disable stops probes, enable restarts probes. VPP dataplane test (tests/02-vpp-lb/) - Rewrite 01-e2e-lab.robot to match the actual single-VPP topology: test client-to-server ping through VPP bridge domains and verify nginx is serving on all app servers. The previous version referenced a non-existent topology file and tested OSPF/BFD between two VPP nodes that don't exist in this lab. Build infrastructure - Add 'make robot-test' target with TEST= for suite selection. - Add tests/.venv target for Robot Framework virtualenv. - Make IMAGE optional in rf-run.sh. - Add .gitignore entries for test output, venv, logs, and clab state.
maglevd
Health checker and gRPC control plane for VPP Maglev load balancing.
Build and Install
make # builds build/<arch>/maglevd and build/<arch>/maglevc
make test # runs all tests
make pkg-deb # Creates a debian package for arm64 and amd64
Requires Go 1.25+ and (for make proto) protoc with protoc-gen-go and
protoc-gen-go-grpc.
Produces vpp-maglev_<version>_amd64.deb and vpp-maglev_<version>_arm64.deb
in the build/ directory by cross-compiling with GOOS=linux GOARCH=<arch>.
Requires dpkg-deb (available on any Debian/Ubuntu host).
Running
After installing, the unit is enabled but not started automatically:
# edit /etc/vpp-maglev/maglev.yaml, then:
systemctl enable --now vpp-maglevd
Or run the server and client by hand:
maglevd --config /etc/vpp-maglev/maglev.yaml --grpc-addr :9090
maglevd --version # print version and exit
maglevc --server localhost:9090 # interactive shell
maglevc show frontends # one-shot
maglevc -color=false show backends # one-shot, no ANSI color
maglevc set backend nginx0-ams pause
Send SIGHUP to maglevd to reload config without restarting.
maglevd requires CAP_NET_RAW for ICMP health checks.
Check out a minimal configuration file in [debian/maglev.yaml].
See docs/user-guide.md for flags, signals, and maglevc usage.
See docs/config-guide.md for the full configuration reference.
See docs/healthchecks.md for health state machine details.
Docker
docker build -t maglevd .
docker run --cap-add NET_RAW -v /etc/vpp-maglev:/etc/vpp-maglev maglevd
