Wilbur Randoli

Project developed by Wilbur to Randoli.

In the steps below I will describe the project and its purpose.

Project

A REST API using with Enterprise Integration Patterns with Apache Camel to perform CRUD operations to another application with Spring Boot, Hibernate, PostgreSQL, Container and Cloud Concepts to save Events.

You can find details how run application below, and how to use the API, inside project exists a file Randoli.postman_collection.json or Camel API DOC with more details about request.

Access APP

To access the application you need to use the following URL:

• AWS/EC2 with K8S - http://camel.wilbur.cloud
• Camel API DOC

Actually exists two EC2 instances in the AWS with this application:

One master instance and one slave instance.

The master contains Rancher to manipulate others VMs.

• RANCHER AWS/EC2 - https://rancher.wilbur.cloud

Example above, but with one master and 3 slaves (in our case we just have one slave to reduce cost)

Architecture

The challange request a new REST endpoint that accepts a json payload and saves it in the database. Each payload may contain one or more records. Each record contains one or more events. To save this without change Client API I used the SPLIT pattern.

apachecamel

• Example of Payload:

{
  "batchId":"0310abf6-d1f5-a1b3-8fb0-36fe934b1f28",
  "records":[
    {
      "transId":"0000abf8-d1f5-4536-8fb0-36fe934b1f28",
      "transTms":"20151022102011927EDT",
      "rcNum":"10002",
      "clientId":"RPS-00001",
      "event":[
        {
          "eventCnt":1,
          "locationCd":"DESTINATION",
          "locationId1":"T8C",
          "locationId2":"1J7",
          "addrNbr":"0000000001"
        },
        {
          "eventCnt":2,
          "locationCd":"CUSTOMER NUMBER",
          "locationId1":"0007316971"
        },
        {
          "eventCnt":3,
          "locationCd":"OUTLET ID",
          "locationId1":"I029"
        }
      ]
    }
    ...
]}

How to run the application

OBS: before all part below you need the Randoli Spring Boot CRUD application running (or just run docker compose option).

To run application in development mode

• to run with mvn in development mode (with automatic H2 database)

mvn spring-boot:run -Dspring-boot.run.profiles=dev

• after start application to analyze REST API with API DOC

http://localhost:8082/integration/api-doc

---

To run application with containerized environment

Docker

To run application with Docker, stay in the same directory with Dockerfile and run:

• package application

mvn clean package

• build container

docker build --tag wilbur-camel:1 .

• run app container in DEV mode

docker run -p 8082:8082 -e ENV_APP="dev" wilbur-camel:1

---

• run app container in PROD mode

docker run -p 8082:8082 wilbur-camel:1

• after start application to analyze REST API with API DOC

http://localhost:8082/integration/api-doc

---

Docker Compose

To run application with Docker Compose

docker-compose up

• after start application to analyze REST API with API DOC

http://localhost:8082/integration/api-doc

---

To send image to repository (in this case Docker Hub)

• build and tag image

docker build -t wilbur-camel:1 .
docker tag wilbur-camel:1 xwilburdev/camelapi:1

• login to Docker Hub

docker login --username=<username>

• push image to Docker Hub

docker push xwilburdev/camelapi:1
