1. 1 Social IRC bots in the cloud with Node.js and MongoDB Marek Jelen PaaS Evangelist, Red Hat MongoLondon, 2013
2. 2 i. basic understanding what cloud is and what it is not ii. you are a developer and you know what Node.js iii. basic knowledge of MongoDB iv. questions are good! v. questions are awesome! vi. discussion is preferred to my monologue My expectations
3. 3 What is IRC? • Communication protocol • Open (RFC1459) & Simple • Text based • Realtime-communication • Group chat & One-to-One chat • Users => #channels <= Bots • Clients, Bouncers, Bots
4. 4 Basic IRC commands • /join #openshif • /msg mjelen This is awesome • /me is presenting in London • /topic Don't be afraid to ask questions.
5. 5 Is it any good? • Basic communication channel of tech companies • Community building environment • Support channel for users • etc. etc. etc. • OpenSource servers & clients (standalone, web)
6. 6 What is OpenShift? Red Hat's free, auto-scaling Platform as a Service (PaaS) for applications in the cloud.
8. 8 Looks great, but what’s the catch? • OpenShif is free-as-in-beer & free-as-in-freedom • Three times 0.5GB RAM/1GB storage • Need more resources, just ask! • We are in Developer Preview • Sign up at openshift.com • Promo code: MongoDBLondon
9. 9 Three flavours • OpenSource project => OpenShif Origin • Enterprise ready product => OpenShif Enterprise • Service by Red Hat => OpenShif Online
10. 10 And now, let's build And now, let's build some bots some bots
11. 11 My bots on OpenShift (1) • Create new deployment environment • rhc app create ircbot nodejs • clones a git repository locally • setups node.js environment • allows you ssh access • provides logs tailing • sets public DNS records
12. 12 My bots on OpenShift (2) • Enter the directory • cd ircbot • Install dependencies • npm install irc -s • Write the code
13. 13 My bots on OpenShift (3) • Record changes (when needed) • git add package.json server.js • Commit the changes • git commit -m “My first commit” • And deploy • git push [origin [master]]
14. 14 My bots on OpenShift (4) • Add MongoDB to the mix • rhc cartridge add mongodb-2.2 -a ircbot • Add RockMongo to inspect MongoDB • rhc cartridge add rockmongo-1.1 -a ircbot • Install dependencies • npm install -S mongojs • Write the code • Connect to MongoDB from application
15. 15 My bots on OpenShift (5) • Record changes (when needed) • git add package.json server.js • Commit the changes • git commit -m “My first commit” • And deploy • git push (origin (master))
16. 16 Conclusion • Three flavors of OpenShif • Origin, Enterprise, Online • Sign up for Online for free • Promo code: MongoLondon • IRC is fun • Open, Simple, Feature-full • Node.js makes it simple to write apps • MongoDB helps with data persistence
