Shows a list of IP addresses viewing the pageApplication launched with docker: node server with redis server as a message broker for scalingand nginx server as a balancer and web server for static client files (index.html andindex.js)

1. git clone this repo
2. Make sure you use latestdocker anddocker-compose
3. Runyarn build fromclient directory to createdist/index.js bundle
4. Rundocker-compose up. It buildsweb,redis andsocket-server containers for you.Rundocker-compose build if you want to rebuild containers
5. Site available on0.0.0.0:80 on Unix-like systems (checkifconfig to find correct IP if not)

Client uses Webpack to create bundledist/index.js.If something changed inclient/src directory,yarn build should be launched to update index.js bundle

1. Unit tests launchyarn test-unit
2. Functional tests must be launched in docker env likedocker exec currentlyviewingapp_socket-server_1 yarn test-func

!!!NOTE!!! In purpose of testing on one machine, websocket server doesn't use real IPs, but number which changed every 10 seconds.

When user opens a tab in browser, number N assigned to this tab via socket connection.

When user opens the second tab in browser, application assigns the same number N or the new number M.

IF the second tab assigned with number N and user closes the first tab, it's "IP-number" still in the list,because there is at least one tab.It allows to see how would it work if user opens many tabs from the same and different computers.

Uncomment server/src/index.js:15 if you wish to see real IP addresses (requires to restart docker container)

1. add deploy script to launchyarn build before docker containers start.Ignore client index.js bundle from get repo
