40. What is docker?
41. It is a lightweight framework (with a powerful API) that provides a lifecycle for building and deploying applications into containers.
42. What is the framework?
43. Framework Components
44. Framework Components Layers
45. Framework Components Layers Containers
46. Framework Components Layers Containers Registry
47. Layers
48. Layers Kernel
49. Layers Kernel cgroups, namespaces, device mapper
50. Layers Kernel cgroups, namespaces, device mapper bootfs
51. Layers Kernel cgroups, namespaces, device mapper bootfs Base image: ubuntu
52. Layers Kernel cgroups, namespaces, device mapper bootfs Base image: ubuntu Image: Add emacs
53. Layers Kernel cgroups, namespaces, device mapper bootfs Base image: ubuntu Image: Add emacs Image: Add Apache
54. Layers Kernel cgroups, namespaces, device mapper bootfs Base image: ubuntu Image: Add emacs Image: Add Apache Writable Container
55. Layers Kernel cgroups, namespaces, device mapper bootfs Base image: ubuntu Image: Add emacs Image: Add Apache Writable Container Framework: BUILD
56. Containers
57. Containers hold the application
58. Containers hold the application collection of images
59. Containers hold the application collection of images run, stop, start, move, delete
60. Containers hold the application collection of images run, stop, start, move, delete an isolated process
61. Containers hold the application collection of images run, stop, start, move, delete an isolated process Framework: RUN
62. Registry
63. Registry Registry stores images
64. Registry Registry stores images Layers are tar ball files with metadata
65. Registry Registry stores images Layers are tar ball files with metadata Public / Private
66. Registry Registry stores images Layers are tar ball files with metadata Public / Private Community warehouse
67. Registry Registry stores images Layers are tar ball files with metadata Public / Private Community warehouse Framework: SHARE
68. Demo: Command Line
69. Demo: Command Line sudo%docker%ps% sudo%docker%images
70. Demo: Command Line sudo%docker%pull%busybox% sudo%docker%run%busybox%/bin/echo%hello%world
71. Demo: Command Line sudo%docker%run%7i%7t%busybox%sh% sudo%docker%ps%7a
72. Demo: Command Line sudo%docker%diff%066882d91690%
73. Docker Architecture Client-server application Can run on the same box or remotely Communicate through sockets Uses a RESTful API Client sends command Daemon executes command
74. Dockerfile A set of instructions Simliar to a Makefile or Vagrantfile Declarative
75. Demo: Dockerfile
76. Demo: Dockerfile sudo%docker%run%77name%redis%7d%7hunderbird/redis
77. Demo: Dockerfile %%%%sudo%docker%run%77link%redis:cli%7i%7t%% 
 % %%%%%%%% % % % % ubuntu:12.10%/bin/bash
78. Demo: Dockerfile % % apt7get%update% % % apt7get%7y%install%redis7server% % % service%redis7server%stop
79. Demo: Dockerfile % % env%|%grep%DB_% % % redis7cli%7h%$DB_PORT_6379_TCP_ADDR
80. Trusted Builds Trusted Builds have a number of advantages. For example, users of your Trusted Build can be certain that the resulting image was built exactly how it claims to be.
81. Demo: Trusted Builds
82. Trusted Builds Created a GitHub repo Subfolder = name Dockerfile goes in there
83. Trusted Builds Use location if using subfolder Repo name by purpose Tag name by purpose Create repo
84. Trusted Builds Check the status https://index.docker.io/ builds/ Tag name by purpose Create repo
