Cloud Foundry 百日行 振り返り
- 1. Cloud Foundry 100-‐day Challenge -‐ Deploy 100 OSS apps onto CF Noburou TANIGUCHI Nippon Telegraph and Telephone CorporaAon / Japan Cloud Foundry Group
- 2. Who I am • Work for NTT – NTT: Nippon Telegraph and Telephone Corp. • A member of cfgrjp – cfgrjp: Japan Cloud Foudry Group • A CF-‐related work – Cheap Update Buildpack hNps://bitbucket.org/nota-‐ja/cheap-‐update-‐buildpack
- 3. Cloud Foundry 100-‐day Challenge • hNp://blog.cloudfoundry.gr.jp/search/ label/百日行 • 「百日行」in Japanese – 百 (hyaku): 100 – 日 (nichi): day – 行 (gyou): discipline, esp. in religional context
- 4. Cloud Foundry 100-‐day Challenge • What – Deploy 100 OSS apps onto CF – One app (and blog post) per (business) day – Since 2015/06/04 – 100 posts finished at 2015/11/16 • 6 core writers + 3 guest writers • All in Japanese
- 5. Cloud Foundry 100-‐day Challenge • Why – More CF recogniAon in Japan – Learn how to make apps run on CF – Explore new features desirable for CF users
- 6. Numbers • Success / Failure • Buildpacks • Services • (ModificaAons)
- 7. Numbers: Success / Failure • OK: 97 • NG: 3 – BuNerfly – Milkode – Zound
- 8. NG: BuNerfly • hNps://github.com/paradoxxxzero/ buNerfly – Web-‐based terminal • cf push => running • Requires password of user 'vcap' ..
- 9. NG: Milkode • hNps://github.com/ongaeshi/milkode – Source code search engine with Web UI • Runs on Heroku • Failed to stage on CF – failed compiling "rroonga" gem's naAve extension • Need to compile some binaries against cflinuxfs2 environment • May run if we have enough Ame
- 10. NG: Zound • hNps://github.com/gre/zound – Real Ame audio streaming (experimental) • cf push => running • Needs hardware audio device for realAme audio rendering
- 11. Numbers: Buildpacks • Total: 113 – Binary (Null): 1 – Go: 4 – Java: 8 – Node.js: 24 – PHP: 22 – Python: 3 – Ruby: 21 – StaAcfile: 16 – app-‐specific: 4 – heroku-‐buildpack-‐apt: 4 – heroku-‐buildpack-‐mulA: 6
- 12. Numbers: Services • Total: 52 – MongoDB: 8 – MySQL: 27 • (incl. ClearDB: 1) – PostgreSQL: 12 – Redis: 3 – SendGrid: 1 • non-‐CF services – MongoDB: 1 – PostgreSQL: 2 • apps using mulAple services: 3
- 13. Some Experience • EtherSheet • Jenkins • SugarCRM • Feedbin • UNICALE • MaNermost • CommaFeed
- 14. EtherSheet • hNps://github.com/ethersheet-‐ collecAve/EtherSheet/ – Web-‐based spreadsheet • PORT • DATABASE_URL
- 15. Jenkins • hNp://jenkins-‐ci.org/ – Most popular CI tool • Very easy with jenkins-‐buildpack • Configs in local file – Jenkins Job Builder – (Database plugin) • Master / Slave composiAon • => Testbed
- 16. SugarCRM • hNp://www.sugarcrm.com/ – Well-‐known open source CRM • PHP extensions • Custom Apache seongs • Configs in local files – Redeploy
- 17. Feedbin • hNps://feedbin.com/ – Ruby on Rails-‐based feed reader • Complex – RDBMS – Redis – (Memcached) – Honeybadger – worker processes • SSL customizability • StaAc file serving customizability • Gemfile.lock generaAon
- 18. UNICALE • hNp://www.unicale.com/ – PHP-‐based simple calendar • Very simple • Data in local files – sshfs
- 19. MaNermost • hNp://www.maNermost.org/ – Open source Slack alternaAve • Most hardest ever • Go + Node.js (+ Ruby) – go-‐buildpack – heroku-‐buildpack-‐apt • with many workarounds • PORT • DATABASE_URL / VCAP_SERVICES
- 20. MulA vs App-‐Specific Buildpack • heroku-‐buildpack-‐mulA – Easy to understand – Less flexible – Bothersome • Requires addiAonal file(s) • App-‐specific buildpack – More flexibile – Less (mostly no) addiAonal files – Requires to be maintained outside of CF
- 21. CommaFeed • hNps://www.commafeed.com/ – Java / Dropwizard-‐based feed reader • My first actual java-‐buildpack study – Know so many features in java-‐buildpack • Finally use Java Main Container and Java OpAons • Configs in local file • PORT • DATABASE_URL
- 22. Three Important Points for Apps • Must have dynamic port binding • Should avoid configs / data in local file • BeNer to get service credenAals from env
- 23. Service CredenAals • VCAP_SERVICES • DATABASE_URL Seems having no standard format – Ruby on Rails – Node.js – Golang – PHP (Pear) • JDBC_URL
- 24. Difficult Things • Problem isolaAon / debugging – staging – starAng – running • Should understand various languages / frameworks • Should understand usage of various buildpacks
- 25. Some Debugging Tricks • Basic – `cf logs <appname>` in another terminal • Staging – JBP_LOG_LEVEL=DEBUG – fork buildpack and `set –x` • StarAng – netcat dummy daemon – (ssh to dea_ng & login to container) • Running / Overall – How to debug the Cloud Foundry Java Buildpack hNp://blog.anynines.com/debug-‐cloud-‐foundry-‐java-‐buildpack/
- 26. Toughest Thing • Pressure of DAILY post
- 27. Good things • Experience how to use Cloud Foundry – (not how to build / operate) – What applicaAon is good for CF – How to migrate exisAng applicaAons to CF – Many skills for trouble shooAng
- 28. A Retrospect • More CF recogniAon – A certain result – But the aNenAon to CF in Japan is sAll not so high • Making apps run on CF – Our team have learned a lot • New features desirable for CF users – Ease of debugging for dev – Ops requirements is yet to explore
- 29. Finally .. • Most applicaAons can be made to run on Cloud Foundry – With a certain effort and Ame • I want MORE apps to be CF-‐ready
