Deployments Before and After Docker

• Based on Selenium
• Each script runs in its own
container
• Performance and Security
A crash test dummy
for your software.

Why New Relic Loves Containers
 Developers Are Productive Faster
Less Yak Shaving, More Coding
 Streamlined Communications Between Teams
Less Handoffs Mean Less Errors
 Better Than VMs
Containers Launch 6x Faster Than VMs
4-6 Times Better Utilization Than VMs
Dennis Jarvis / CC-BY-SA-3.0
 Scale!

14
Why Ops Loves Containers
 No More Racking / Kickstarting Pizza Boxes
Script What You Need
“Build once, run anywhere” for infrastructure
 Much Less Fiddling With Puppet & Chef
Devs own those dependencies now!
 Don’t Fix, Replace
Pongratz / CC-BY-SA-3.0

15
Why Dev Loves Containers
 Faster Provisioning
“I need a place to run a new app...” Done in minutes not weeks!
 Control Of Runtime Environment
Dev owns exactly what the app gets
 Redundancy Is “Easy”
Go N+2 and beyond; stripe across hosts
 Microservices Friendly
One service per container
 Polyglot
Use the best language for the job

Is Docker Ready for Production?

17
Trick Question!
• Docker is a Moving Target
• Boot2Docker/Docker ToolBox/
Now Native Mac/Windows
• Docs are Written for Greenfield development
• “Lots of pain, lots of gain”

 Learning Curve
 Legacy Apps
 Multithreaded Code
 Noisy Neighbors
 Security
Challenges
Luc Viatour / www.Lucnix.be

 What’s Your Host?
 Still Need Tools
 Centurion: Docker Deployment Tool
 Build Ships Containers to Docker Registry
 Centurion Sends Containers to Docker Fleet
 GitHub: Newrelic/Centurion
Limitations
Luc Viatour / www.Lucnix.be

How Do You Know What’s
Happening With Your
Containers?

 Docker Stats Command & Docker API
 Attach to a Running Container
docker -H tcp://<docker-host>:<port#> ps -a | grep <myapp>
docker -H tcp://<docker-host>:<port#> exec -it <containerID> /bin/bash
Looking At Containers

Application
