yatc-project

Yet Another Test Cluster Project - an umbrella for a number of clustered subprojects

Modules and Features

• K8S deployment files (k8s main directory for cluster creation, configuration and tunneling, and in each project subdirs for image building and deployment) to be used on a minikube local instance
• KeyCloak Oauth2 Identity Provider yatc-keycloak with predefined yatc-realm realm
• Postgresql yatc-postgres and MongoDB yatc-mongo databases
• Redis cache yayc-redis
• Kafka message broker (without ZooKeeper) yatc-kafka
• Prometheus monitoring with service discovery yatc-prometheus and Grafana yatc-grafana; integration with metrics data endpoints and exporters
• Log monitoring with Alloy yatc-alloy and Loky yatc-loki, integrated with Grafana, inspired by:
  • https://github.com/docker/awesome-compose/tree/master/prometheus-grafana
  • https://medium.com/@ahmadbilalch891/how-to-set-up-grafana-loki-and-prometheus-locally-with-docker-compose-part-1-of-3-62fb25e51d92
• Spring API Gateway gw-spring-cloud, based on reactive stack, integrated with KeyCLoak for authentication and Redis for session caching
• Spring servlet ms-spring-servlet and reactive ms-spring-reactive based microservices
• RUST Axum microservice ms-rust-axum
• NodeJS Express microservice ms-node-express - Work in Progress
• Propagation of traces (trace_id) using W3C standards (i.e. traceparent header) in http and kafka communications

TODO

• Setup Rust ms to read environment variables, and integration (rest api, database, security, kafka, etc)
• Add some Go ms (full integration as Rust) -> ms-go-fiber and ms-go-gin
• Add some Java (Quarkus) ms (full integration as Rust) -> ms-quarkus-jee and ms-quarkus-munity
• Add some Python ms
• Add some Scala ms
• Add some Nginx server with a basic frontends (Angular & Material / React & MUI / Vue & ?) -> fe-angular-material and fe-react-mui
• Activate OpenAPI / Swagger / Scalar API browsing through a backend gateway / ingress
• Create and persist Grafana dashboards
• Manage USER directive in Dockerfiles to avoid run as root
• Change docker-compose.yaml for rely on module's Dockerfiles and run builds accordingly
• Add a SonarQube (https://hub.docker.com/_/sonarqube) and / or a bundled OWASP Dependency Tracker (https://hub.docker.com/r/dependencytrack/bundled) for project scanning
• Add OpenAPI online documentation (i.e. using Swagger or Scalar - see here) and propagate it through gateway on dedicated host.

Not here, not now:

• Include a Dockerfile.k8s.graalvm for java based microservices: tested, but not good to be tested on this infrastructure, because huge image building times and bad dependency compatibility in Spring Session.
• Add Camunda Zeebe (v8) workflow engine for orchestration (see https://docs.camunda.io/docs/self-managed/setup/deploy/local/docker-compose/): too many components to be put in the cluster, can't do this on a simple pc. At most, I would try to use Camunda Workflow Engine 7...
