ExGoCD

A Phoenix LiveView rewrite of Thoughtworks GoCD — distributed CI/CD with plugin extensibility, built-in observability, and a Go-powered agent.

---

Quick Start

mix setup              # install deps, create DB
mix phx.server         # start at localhost:4000

With Go agents (process-compose)

docker compose up -d postgres jaeger otel-collector
process-compose up

Starts Phoenix server + CI agent (elixir,postgres) + Docker agent (docker). See process-compose.yaml.

Features

Full GoCD parity — pipelines, stages, jobs, materials, VSM, analytics, config-as-code, elastic agents, RBAC, and more. See PARITY.md.

Area	Highlights
Pipeline engine	Scheduling, fan-in, config diff, locking, manual/auto trigger
Agents	WebSocket protocol, Go binary (~10MB), elastic (K8s + Docker)
UI	LiveView dashboard, stage overview popups, Gantt charts, VSM
Config	XML import/export, YAML config repos, templates, wizard
Observability	Built-in OpenTelemetry, Jaeger traces, Grafana dashboards
Plugins	Standalone OTP apps — agent selectors, org hierarchy, auth
Security	RBAC with Bodyguard, per-environment policies, PAT, encryption

Stack

Layer	Tech
Server	Elixir + Phoenix LiveView + Ecto (PostgreSQL)
Agents	Go — statically linked, no cgo
Plugins	Standalone OTP apps via libcluster
Frontend	Phoenix LiveView + Tailwind CSS + daisyUI
Ops	OpenTelemetry, Jaeger, Grafana, Docker Compose

Services

Service	URL
ex_gocd	localhost:4000
Adminer (DB)	localhost:8092
Grafana	localhost:3000
Jaeger (traces)	localhost:16686
smtp4dev (email)	localhost:8025

Testing

mix test                              # full suite (needs Postgres)
EX_GOCD_TEST_NO_DB=1 mix test_no_db   # skip DB tests
bash scripts/quality-gate.sh          # all static analysis + tests
