1. SHIPPING NODE Patrick Heneise
2. :{( #MOVEMBER
7. DEVELOPMENT ——————————— DEPLOYMENT
9. PRODUCTION!
11. DUCKDUCKGO: “NODE.JS DEPLOYMENT”
12. Version Control (git push live) Jenkins/Chef/Jake… ¿¿Lint all the things (QA)?? Copy Pray
13. CONTINUOUS INTEGRATION
14. CONTINUOUS DEPLOYMENT
15. –me “Integrating a continuous pain in the butt”
16. DIVING DEEPER
17. ONE SERVICE, ONE BOX THINKING
18. –Michael Brunton-Spall, Velocity EU 2014, @bruntonspall “Developers are simple people. They don't to know how `apt` works; don’t need to know. They just want their application deployed.” “They just know enough to be dangerous.”
20. SSH LOGIN you maybe forgot to add your ssh public key to the deployment, so you’ll have to enter some weird complicated password you got into your mailbox and then enter another keyword and again, just to make sure …
22. CONFIGURE YOUR FIREWALL
24. COMPILE NODE.JS FROM SOURCE?????
26. Configure all the things! Get stuck Call your sysadmin buddy / operations hours later … Runs like a beast!
27. ALL THE THINGS YOU SHOULDN’T NEED TO CARE/WORRY ABOUT
29. YOU JUST WANTED …
31. COREOS security consistency reliability automatic discovery of new hosts automatic app scheduling
32. DOCKER Build Ship Run
33. Dependency management Containers can be moved around Container is NOT a Linux
34. NODE.JS well, you know …
35. LET’S START SIMPLE 1. Package your app into a Docker image 2. Create a cloud-config file 3. Provision Virtual Machines/Machines with CoreOS 4. There’s no step 4
36. DOCKERFILE
37. FROM centos:centos7 MAINTAINER Patrick Heneise <patrick@blended.io> # Enable EPEL for Node.js RUN rpm -Uvh http://mirror.uv.es/mirror/fedora-epel/7/x86_64/e/epel- release-7-2.noarch.rpm # Install Node.js and npm RUN yum update -y RUN yum install -y make GraphicsMagick npm # Bundle app source COPY . /src # Install app dependencies RUN cd /src; npm install CMD ["node", "/src/app.js"]
38. CLOUD CONFIG
39. #cloud-config coreos: etcd: discovery: https://discovery.etcd.io/<token> addr: $private_ipv4:4001 peer-addr: $private_ipv4:7001 fleet: public-ip: $private_ipv4 units: - name: etcd.service command: start - name: fleet.service command: start
41. PACK YOUR THINGS run boot2docker docker build -t ‘you/yourrepo’ . docker run you/yourrepo docker push you/yourrepo
42. PREPARE THE FLEET
44. - name: oneshot.service command: start enable: true content: | [Unit] Description=OneShot Cat Image Processor After=docker.service Requires=docker.service [Service] TimeoutStartSec=0 ExecStartPre=-/usr/bin/docker kill imagebox ExecStartPre=-/usr/bin/docker rm imagebox ExecStartPre=/usr/bin/docker pull patrickheneise/oneshot-docker-demo ExecStart=/usr/bin/docker run --name imagebox patrickheneise/oneshot- docker-demo ExecStop=/usr/bin/docker stop imagebox
46. DEMO
47. Run a CoreOS cluster on your host as vm Run a CoreOS cluster in staging/testing Run all the tests/lints/… on a live cluster Deploy to various clusters So many possibilities!
48. COREOS + DOCKER + NODE.JS
49. Less configuration Less trouble Less worry More free time :-)
50. DO YOU HAVE A DATE WITH A CONFIG FILE TONIGHT?
51. WE’RE NOT THE *NIX NERDS HIDING BEHIND CONFIG FILES!
52. WE’RE THE COOL KIDS ON THE PLAYGROUND
53. WE’RE THE FOLKS WITH THE COOL SHIRTS!
54. THANKS
55. COOL STUFF TO TRY Google Kubernetes (Cluster Manager)
