Docker + IBM Social Software
What and why
4

Docker
• Docker is an open platform for developing, shipping, and running applications.
• Docker is designed to deliver your applications faster.
• With Docker you can separate your applications from your infrastructure and treat your
infrastructure like a managed application.
5

Docker and containers in a few slides
Docker is a way to “package” your software in an
image:
 File system
 System security (user/groups) & settings
 TCP Network (ports that needs to be
reachable)
 Image inheritance is possible (incremental
specialization)
Docker is a way to “ship & run” your software to
other systems:
• Start an “image” to get a container where your
software runs
• Manage containers (start/stop/control etc)
• The container runs regardless of the actual
(underlying) system (VM, bare metal, etc)
6

Docker History
• Docker was released as open source in March 2013
• Solomon Hykes started Docker in France as an internal project within dotCloud, a platform-
as-a-service company, with initial contributions by other dotCloud engineers including
Andrea Luzzardi and Francois-Xavier Bourlet.
• with the release of version 0.9, Docker dropped LXC as the default execution environment
and replaced it with its own libcontainer library written in the Go programming language.
(Google’s OpenSource Programming Language )
• In 2015, the project had over 25,600 GitHub, over 6,800 forks, and nearly 1,100
contributors.
• In May 2016 analysis showed the following organizations as main contributors to Docker:
The Docker team, Cisco, Google, Huawei, IBM, Microsoft, and Red Hat.

The underlying technology
Namespaces
• Pod: pid isolation
• Net: network interface
• Ipc: interProcess
Communication
• Mnt: managing mount point
• Uts: isolating kernel and
version identifier
Control groups
limits and isolates
the resource usage of a
collection of processes
Union File Systems
operate by creating layers
very lightweight and fast
CONTAINER (libcontainer)

Docker keys components
9
• Docker engine
• Docker machine
• Docker registry

Docker Engine
Docker Engine is a client-server application with these major components:
• A server which is a type of long-running program called a daemon process.
• A REST API which specifies interfaces that programs can use to talk to the daemon and
instruct it what to do.
• A command line interface (CLI) client.
10

Docker Machine
• Docker Machine is a tool that lets you install
Docker Engine on virtual hosts, and manage
the hosts with docker-machine commands.
• You can use Machine to create Docker
hosts on your local Mac or Windows box, on
your company network, in your data center,
or on cloud providers like AWS or Digital
Ocean.
11

Docker registry
The registry is a server application that lets you distribute Docker images.
https://hub.docker.com/explore/
12https://hub.docker.com/u/ibmcom/

Docker registry… On-premises
Docker hub free-to-use, hosted Registry, plus additional features (organization
accounts, automated builds, and more).
13

Docker registry… On-premises
Running your own Registry is a great solution to integrate with your CI/CD system.
(Continuous Integration/Delivery)
A notification from the Registry would then trigger to notify other systems that a new
image is available.
It’s also an essential component if you want to quickly deploy a new image over a large
cluster of machines.
Finally, it’s the best way to distribute images inside an isolated network.
14

Availability
• Linux
• Windows
• Mac
• Aws
• Azure
• Bluemix
• …
Docker’s architecture
Docker uses a client-server
architecture !
The same image can run
on your laptop, on your server, on your cloud
15

HA is also available
Starting from version 1.12 Docker swarm was integrated into Docker Engine in swarm
mode:
Highlights:
• Cluster management integrated with Docker Engine
• Multi-host networking
• Load balancing
• Secure by default (TLS stricly enforced for communications)
• Scaling
16

Why Docker
Create images to support developers (standard deployment)
Keep an archive of images for every software release to perform back-version
debugging/testing (start a clean server in minutes)
Consolidate multiple servers on a single powerful machine but maintain complete
isolation
17

Container vs Virtual Machine
Virtual machine runs a dedicated
operating system.
Each VM has its own binaries/libraries
and application(s) that it services,
and the VM may be many gigabytes
in size
Each container shares the host OS kernel
and, usually, the binaries and libraries, too.
Shared components are read-only
This makes containers exceptionally “light” –
containers are only megabytes in size and
take just seconds to start, versus minutes for
a VM

IBM announces zSystem
for Docker
Download here: http://www.ibm.com/developerworks/linux/linux390/docker.html
IBM and Docker offer integrated container solutions that
can meet the diverse needs of enterprises.
Supporting the creation and deployment of multi-platform,
multi-container workloads across hybrid infrastructures,
IBM and Docker accelerate application delivery and
enable application lifecycle management for Dockerized
containers.
21

IBM announces Docker on
IBM PureApplication System
The good news is that Docker is now supported on IBM
PureApplication v2.1! You can now use Docker containers in the
virtual system patterns that you create and you can reference Docker
images that are stored on Docker Hub or in a private Docker registry
that runs inside PureApplication. Taking advantage of the Docker
containers on PureApplication is as easy as building patterns.
22

IBM Bluemix
• IBM Bluemix provides built in DevOps services to manage source code and to build, test
and deploy applications to Bluemix.
• For more complex scenarios IBM provides the Continuous Delivery toolset UrbanCode to
deploy hybrid applications to the cloud and on-premises and to deploy composite
applications with multiple components or microservices.
• The store application uses one container on Bluemix . Containers running in a Docker
Swarm cluster on-premises.

How To: Create Docker images with
IBM Social Software
26

Prepare your Container
• Prepare the Installation script
• Using Silent installation method
• Preparing the response file and whatever you need to
complete setup
• Create your Docker File and deploy it.
27

Docker Image
A docker image is a read-only template for creating containers.
• Manual: Start from a base image, build your customization and commit the new image.
• DockerFile: Use a script.
DockerFile anatomy
A “DockerFile” is a text file with docker commands, it
• Declares the “base image” to inherit from
• Copies files to the image filesystem
• Executes commands in the image to setup things
• Declares “VOLUME” mappings
• Declares ports to “EXPOSE”d.
28

Docker File Anatomy
Identifies which folder you need to share
between container and host
Identifies which image you want to use
Identifies which command you need to
execute inside the containers
FROM ubuntu:latest
VOLUME [/opt/data]
VOLUME [/etc]
VOLUME [/home]
RUN apt-get install -y
aptitude
net-tools
libxtst6
libxi6
libcanberra-gtk3
gtk+
COPY DB2_Svr_10.5.0.3_Linux_x86-64.tar.gz /tmp/db210.5/ Copy your Packages into the containers
29

Prepare IBM Silent Installation
You can use the IBM installation manager from command line, and create your response
file sample!
IBMIM –record /tmp/was9.xml -skipInstall /tmp/IBM/
<?xml version='1.0' encoding='UTF-8'?>
<agent-input>
<variables>
<variable name='sharedLocation' value='/opt/ibm/IMShared'/>
</variables>
<server>
<repository location='/tmp/sw-repo/WAS_ND_9'/>
<repository location='/tmp/sw-repo/SDK_JAVA_V8'/>
</server>
<profile id='IBM WebSphere Application Server V9.0' installLocation='/opt/ibm/WebSphere/AppServer'>
<data key='cic.selector.arch' value='x86_64'/>
<data key='cic.selector.nl' value='en,en'/>
</profile>
<install>

<offering profile='IBM WebSphere Application Server V9.0' id='com.ibm.websphere.ND.v90' version='9.0.0.20160526_1854' features='core.feature,ejbdeploy,thinclient,embeddablecontainer'/>

RUN mkdir /var/lock/subsys
# Volume definition

EXPOSE 80 443 9060 9043
RUN rm /tmp/sw-repo -R
A data volume is a specially-designated directory within one or more containers that bypasses the Union File System.
Data volumes provide several useful features for persistent or shared data:
Volumes are initialized when a container is created. Data volumes can be shared and reused among containers.
Changes to a data volume are made directly.
Changes to a data volume will not be included when you update an image.
Data volumes persist even if the container itself is deleted.
Data volumes are designed to persist data, independent of the life cycle of the container.
The EXPOSE instruction informs Docker that the container listens on the specified network ports at runtime
