| Note: I created this for Cisco Live San Diego 2015. | |
| My name is Ashley. | |
| I am the explainer, | |
| In the next 10 mins, | |
| We talk containers | |
| Chapter 1: The situation | |
| Let’s meet a web app | |
| Contained within it, | |
| you’ll find a db, | |
| a front end and back. | |
| APIs and queues! | |
| Postgres and node! | |
| Hive and hadoop! | |
| Python and go! | |
| Imagine the test | |
| matrix! I don't know... | |
| We must test and ship! | |
| We must black box! | |
| We must regress! | |
| We must do this in | |
| Two hours or less! | |
| So you can enjoy | |
| Our new awesome feature, | |
| We need to find Sam, | |
| Our QA test leader. | |
| We need Abeer, | |
| Our Ops engineer! | |
| We ask Sam to test. | |
| He looks with great fury. | |
| We nod to Abeer | |
| She says in a hurry... | |
| We now do DevOps, | |
| We share all our fears. | |
| Find a new way | |
| To package your gear. | |
| Virt’alize says Sam! | |
| Yes, yes! Hip hooray! | |
| We needn’t worry | |
| ab’t diffr’nce today. | |
| Yes yes, virt’lize! | |
| Yes yes, we must size, | |
| Our big boxes | |
| To launch our surprise. | |
| Containers! She shouts. | |
| Virtualize, Sam pouts. | |
| We suddenly realize | |
| There are new routes! | |
| Chapter 2: History | |
| Containers aren’t new. | |
| In ’79, | |
| Unix V7. | |
| The C-groups design. | |
| Linux Containers, | |
| AKA LXC, | |
| Set the bar high. | |
| Docker came to be. | |
| Containers? What are they? | |
| A VM is close. | |
| Sans hypervisor, | |
| They talk with the host. | |
| One OS is all. | |
| Immutable blocks. | |
| Docker is one kind. | |
| Containers are rocks. | |
| You said best of both. | |
| Virtual and 'tainer | |
| They can cooexist | |
| In your data centers | |
| Chapter 3: Developers | |
| Meet Tracy, the dev. | |
| Her first day is now. | |
| She has a new MacBook, | |
| And starts to install. | |
| Npm and git! | |
| Mongo and bower! | |
| Ember and Grunt! | |
| It might take an hour! | |
| Set this env var! | |
| Oh, I forgot! | |
| You need a debugger, | |
| To get your box set. | |
| You must match the server. | |
| You need to cluster. | |
| All these configs! | |
| Looming disaster! | |
| Abeer speaks up. | |
| Go to this wiki! | |
| boot2docker will | |
| Get you up quickly. | |
| Chapter 4: Continuous Integration | |
| Jenkins is next. | |
| He is our CI. | |
| Testing takes so long, | |
| I poke out my eyes! | |
| Says Abeer... | |
| "VMs are so bloated. | |
| They take time to start. | |
| They have a whole OS, | |
| And mem’ry runs short." | |
| Abeer talks again, | |
| "It’s totally fine | |
| With our new Docker | |
| We test run in time! | |
| Chapter 5: QA | |
| Test Security, | |
| Perf and Functional. | |
| Now our test mode is | |
| Comply not Govern. | |
| Pull it from the hub. | |
| It’s easy to share. | |
| Build it like magic. | |
| Versioned and not stale. | |
| Sam comes around. | |
| Now he sees the light. | |
| He realizes | |
| Profit, speed. No fight! | |
| Chapter 6: Ops | |
| Uri is from Ops | |
| Think intensity! | |
| He wants to increase | |
| Compute density | |
| Uri agrees that | |
| VMS are like cows | |
| Only few of them | |
| Can fit as allows | |
| 10 LXCs now | |
| Replace 1 VM. | |
| Now, that’s density! | |
| With servers to trim. | |
| With servers to trim, | |
| Eureka! Uri yells! | |
| We now can add | |
| Ecommerce that scales. | |
| Chapter 7: Microservices | |
| In software engineering | |
| We like to abstract | |
| By breaking it up, | |
| Risk doesn’t get jacked. | |
| No! No Monoliths! | |
| No! No more curses! | |
| Yes! Yes! Loosely coupled. | |
| Yes Microservice! | |
| Microservices | |
| Now, what does it mean? | |
| Break up our product | |
| Into separate domain. | |
| Each part can be patched | |
| Each team’s focus can narrow | |
| We now have micro teams | |
| Who and be more agile! | |
| Chapter 8: In Conclusion | |
| We met Sam | |
| We met Tracy | |
| We met Jenkins | |
| We met Uri | |
| Velocity! | |
| Efficiency! | |
| Compute Density! | |
| Dev and Ops, | |
| QA and CI, | |
| Containers can help | |
| EVERYBODY! |
