Common ports
JHipster configures many tools and services, and each of them will likely use one or several ports. Here is a documentation to help understand what each port does, and help in case of a port conflict.
Please note that as per the JHipster Policy 1, the standard port for each technology is used, unless that causes a problem (that should be explained here).
The ports here are listed in order, but the most common questions are for ports 8080, 9000 and 9060.
| Port | Description |
|---|---|
| 80 | Traefik HTTP entrypoint |
| 2181 | Zookeeper (used with Kafka) |
| 3000 | Grafana |
| 3306 | MySQL and MariaDB |
| 5000 | Logstash |
| 5432 | PostgreSQL |
| 5601 | JHipster Console (based on Kibana) |
| 5701 | Hazelcast |
| 8080 | JHipster application back-end development port (Spring Boot server) / Traefik admin UI |
| 8081 | JHipster microservice default port |
| 8091 | Couchbase - Web administration port |
| 8092 | Couchbase - API port |
| 8093 | Couchbase - used by query services for REST/HTTP traffic |
| 8301 | Consul - serflan-tcp and serflan-udp |
| 8302 | Consul - serfwan-tcp and serfwan-udp |
| 8300 | Consul - server |
| 8400 | Consul - RPC |
| 8500 | Consul - HTTP port with the Web UI |
| 8600 | Consul - DNS |
| 8761 | JHipster Registry (Netflix Eureka) |
| 9000 | JHipster front-end development port with BrowserSync |
| 9042 | Cassandra - CQL |
| 9060 | JHipster front-end development port with Webpack hot-reload |

| 11210 | Couchbase - Internal/external bucket port |
| 18080 | H2 (embedded database) running inside a monolith. Default port is normally 9092 but this would cause a conflict with Kafka, so it is fixed as "1" + "Spring Boot port" |
| 18081 | H2 (embedded database) running inside a microservice. See line above for more information |
| 27017 | MongoDB |
