1. Derby DevOps Meetup
Docker Containers, Microservices, Hands on Labs (11/7/2017)
Matt Bentley, Senior Solutions Engineer
Docker, Inc

2. Agenda
• Docker Basics

• Development with Docker
• End to end CaaS Workflow
• Hands on Labs
• DockerCon Europe 2017 Recap
• Q&A

3. Docker Basics

4. 4
Some Docker vocabulary
Docker Image
The basis of a Docker container. Represents a full application
Docker Container
The standard unit in which the application service resides and executes
Docker Engine
Creates, ships and runs Docker containers deployable on a physical or
virtual, host locally, in a datacenter or cloud service provider
Registry Service (Docker Hub or Docker Trusted Registry)
Cloud or server based storage and distribution service for your images

5. 5
Docker File System
• Logical file system by grouping different file system primitives into
branches (directories, file systems, subvolumes, snapshots)
• Each branch represents a layer in a Docker image
• Allows images to be constructed / deconstructed as needed vs. a huge
monolithic image (ala traditional virtual machines)
• When a container is started a writeable layer is added to the “top” of the
file system

6. 6
Copy on Write
Super efficient:
• Sub second instantiation times for containers
• New container can take <1 Mb of space
Containers appears to be a copy of the original image
But, it is really just a link to the original shared image
If someone writes a change to the file system, a copy of the affected
file/directory is “copied up”

7. 7
Build Efficient, Reusable Images
• Utilize a hierarchical order of images
ubuntu
java
grails tomcat
appA appB
nginx nodejs
appA appB

8. Dockerfile – Linux Example
8
• Instructions on
how to build a
Docker image
• Looks very similar
to “native”
commands
• Important to
optimize your
Dockerfile

9. Dockerfile – Windows Example

10. 10
What about data persistence?
• Volumes allow you to specify a directory in the container that exists outside of the
docker file system structure
• Can be used to share (and persist) data between containers
• Directory persists after the container is deleted
• Unless you explicitly delete it
• Can be created in a Dockerfile or via CLI

11. Docker Platform - The Vehicle for Modernization
Step 1:
Consolidate
Save money via consolidation
of VMs
Or
cut out VM tax by running
Docker directly on baremetal
Step 2:
Refresh Infra
Containers on modern
infrastructure via Docker and
run on Synergy
Step 3:
Enable Hybrid IT
Utilize portability of Dockerized
apps to enable Hybrid IT strategy
Bare Metal
● Single app running on
bare metal
● Average 15% utilization
of infrastructure
Virtualization
● No multiple apps per
server
● VM sprawl leads to
same 15-20% utilization
Containerization
● Containers run within
VMs
● 50% consolidation of
VMs
APP
1960s Bare Metal
Servers Introduced 1999 VMware virtualization
2013 Docker

12. 12
Containers like VMs?
• Bare metal = House
• VMs = Apartments
• Containers = Dorms

Scale in seconds
Modernize Traditional Applications: Customer Benefits
Portable
Port legacy apps across
hybrid infrastructure
Enable Hybrid or Multi-
Cloud strategies
No change to app code

18. Development with Docker

19. Docker for Mac and Windows
• Utilize native hypervisor capabilities (xhyve & Hyper-V) to run Docker
• Provide seamless local experience
• Windows 10 and macOS El Capitan 10.11 and above supported
• Docker Toolbox still available for unsupported platforms
• Build and Test using same bits as deployed to production

20. IDE Integration
• Visual Studio 2017
• Provide native integrations with Docker for building and running
applications
• Build, run, and publish
• Java
• IntelliJ, Netbeans, Eclipse
• Node.js
