This document explains how to run CCFE (in development mode) with Docker

Requirements

  1. Docker environment up & Running

Goals

At the end of this exercise, you will have a CCFE running in dev mode under docker on your localhost on 8090 port

Steps

  1. Get the source code of CCFE
[nareshv@localhost Opensource]$ git clone https://github.com/linkedin/cruise-control-ui

  1. Create Dockerfile (if not in repo)
[nareshv@localhost Opensource]$ cd cruise-control-ui/
[nareshv@localhost cruise-control-ui]$ vi Dockerfile
FROM node:10

WORKDIR /opt/cruise-control-ui

COPY package*.json ./

RUN npm install

COPY . .

EXPOSE 8090

CMD [ "npm", "run", "dev" ]
  1. Create .dockerignore (if not in repo)
[nareshv@localhost cruise-control-ui]$ vim .dockerignore
node_modules
npm-debug.log
  1. Build the image from local source code
[nareshv@localhost cruise-control-ui]$ docker build -t nareshv/cruise-control-ui .

  1. Verify the image thats just built
[U@localhost cruise-control-ui]$ docker images

  1. Start the CCFE (dev mode)
[nareshv@localhost cruise-control-ui]$ docker run -p 8090:8090 -d nareshv/cruise-control-ui

  1. Verify the app by fetching config
[nareshv@localhost cruise-control-ui]$ curl http://localhost:8090/static/config.csv
dev,dev,/kafkacruisecontrol/
  1. Open CCFE in browser

Open http://localhost:8090 and you should see CCFE running.

NOTE: As part of the build step-4, please create appropriate static/config.csv URL contents which has right CC REST API values. NOTE (Reverse Proxy): This example doesn't work with Reverse proxy method as we are running CCFE in Development mode within Docker NOTE (CORS): Please use absolute URLS in static/config.csv. This also requires additional setup of CC as mentioned in wiki
