1. Get used to it !
2. Julien Vey @julienvey
3. Pierre Padrixe @undefd
5. What is Docker ?
6. What is Docker ?
7. When can I use Docker ?
8. Sandbox
9. $ ./install-XXX.sh !
10. $ ./install-XXX.sh Error during install ! …
11. $ ./install-XXX.sh Error during install ! … $ ./uninstall-XXX.sh !
12. $ ./install-XXX.sh Error during install ! … $ ./uninstall-XXX.sh Could not remove file xxx !
13. $ ./install-XXX.sh Error during install ! … $ ./uninstall-XXX.sh Could not remove file xxx ! ! FAIL !
14. Please Docker, help me !
15. $ docker run $ ./install-XXX.sh Error during install !
16. $ docker run $ ./install-XXX.sh Error during install ! Try Again !
17. $ docker run $ ./install-XXX.sh Error during install ! Try Again ! $ docker run $ echo "Some conf" > XXX.cfg $ ./install-XXX.sh Success !
18. Repeatability
19. $ ./myscript.sh !
20. $ ./myscript.sh $ ./myotherscript.sh !
21. $ ./myscript.sh $ ./myotherscript.sh $ rm -rf myscriptdir !
22. $ ./myscript.sh $ ./myotherscript.sh $ rm -rf myscriptdir ! OOPS !
23. Please Docker, help me !
24. RUN ./myscript.sh
25. RUN ./myscript.sh RUN ./myotherscript.sh
26. RUN ./myscript.sh RUN rm -rf myscriptdir RUN ./myotherscript.sh
27. RUN ./myscript.sh RUN rm -rf myscriptdir RUN ./myotherscript.sh OOPS ?
28. RUN ./myscript.sh RUN rm -rf myscriptdir RUN ./myotherscript.sh $ docker commit $id me/snap $ docker commit $id me/snap $ docker run me/snap
29. Setup your Development environment
30. A development Environment Today
31. Tomcat Vert.x NodeJS Apache PHP Mongo
32. $ install $ install $ install $ install $ install $ install Tomcat Vert.x NodeJS Apache PHP Mongo
33. Tomcat Vert.x NodeJS Apache PHP Mongo $ configure $ configure $ configure $ configure $ configure $ configure
34. Do this for each Developer $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure $ configure
35. Too Many Steps !
36. Please Docker, help me !
37. Tomcat Vert.x NodeJS Apache PHP Mongo $ configure $ configure $ configure $ configure $ configure $ configure Configure a Container Once
38. just run it for each developer $ docker run $ configure $ configure $ configure $ configure $ configure $ configure $ docker run $ configure $ configure $ configure $ configure $ configure $ configure $ docker run $ configure $ configure $ configure $ configure $ configure $ configure
39. On any (Linux) environment $ docker run $ configure $ configure $ configure $ configure $ configure $ configure $ docker run $ configure $ configure $ configure $ configure $ configure $ configure $ docker run $ configure $ configure $ configure $ configure $ configure $ configure
40. Or split by services $ docker run NodeJS $ configure Apache $ configure $ docker run MongoDB $ configure $ docker run
41. Or split by services $ docker run NodeJS $ configure Apache $ configure $ docker run MongoDB $ configure $ docker run and run ONLY what you need
42. PaaS Platform-as-a-Service
43. a PaaS deploys your application
44. your application needs Isolation
45. your application needs Fast Startup Time
46. Lucky you !
47. Docker is isolated
48. Docker is Fast
49. PaaS Providers already use Containers
50. OpenShift Heroku Docker INC use LXC
51. Flynn Deis Dokku are built with Docker
52. Isolation VS Performance
53. Sometimes, a Virtual Machine is Not Enough
54. You need Bare Metal Performance
55. You need Bare Metal Performance
56. But you Don’t want This Bare Metal Server
57. You’d Prefer have This Bare Metal Server
58. By Isolating your Apps in Containers, ! You provide Isolation without giving up Performance
59. Continuous Deployment
60. Deliver Code Test Deploy
61. Deliver Code Test Deploy to Integration Deploy to Staging Deploy to Production
62. Deliver Code Test Deploy to Integration Deploy to Staging Deploy to Production Install environment Configure Migration scripts Deploy deliverable Install environment Configure Migration scripts Deploy deliverable Install environment Configure Migration scripts Deploy deliverable
63. We have to change the Delivery Unit
64. Deliver a container
65. Deliver a container Install environment Configure Migration scripts Deploy deliverable
66. Deliver a container Test Deploy to Integration Deploy to Staging Deploy to Production
67. Deliver a container Test Deploy to Integration Deploy to Staging Deploy to Production $ docker run $ docker run $ docker run Install environment Configure Migration scripts Deploy deliverable Install environment Configure Migration scripts Deploy deliverable Install environment Configure Migration scripts Deploy deliverable
68. The Container is the new Delivery Unit
69. Demo Time !
70. User $git push triggers build - build project - build container deploys and run container
71. User $git push triggers build - build project - build container deploys and run container Everything is a container
72. in order to build the container $docker build <mycontainer> github.com/jpetazzo/dind
73. What Else ?
74. User $git push triggers build with Promoted Builds Plugin promote to staging promote to integration promote to production
75. $ docker run base echo Questions?
76. Thanks
