poks-server

Microservices discovery server

Build

mvn package

Dependencies

https://github.com/wey-yu/poks-core-libs

Run

⚠️ You need to set some environment variables

• SERVER_CREDENTIALS a kind of token or password (services must send the same token)
• PORT this is the http port (poks-server is a web application)
• REDIS_URL (poks-server persist data with Redis, so you need a Redis server)

#!/bin/bash
export SERVER_CREDENTIALS=canarybay
export PORT=8080
export REDIS_URL=localhost

mvn exec:java
# or java -jar target/poks-server-0.0.1-SNAPSHOT-jar-with-dependencies.jar

    operations: product(7, 10): onSet(|data|-> println(data: result())) # == 70

    operations: divide(50, 10): onSet(|data|-> println(data: result())) # == 5

    operations: addition(40, 2): onSet(|data|-> println(data: result())) # == 42

    operations: concat(DynamicObject(): a("Hello"): b(" world!!!"))
      : onSet(|data|-> println(data: result())) # Hello world!!!

  })
