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
