This document discusses Docker orchestration on Azure using Rancher. It begins with an introduction to Docker concepts like containers, images and the Docker workflow. It then demonstrates deploying a Rancher server on Azure, adding nodes, upgrading a sample application, enabling cross-region networking, auto-scaling services, and using a Docker volume plugin to connect to Azure File Storage for persistent storage. The document includes code samples and step-by-step demonstrations of these Rancher and Docker capabilities on Azure.

3. Agenda
Let’s get sure everyone understands
the basics…
“Docker 101”
Show me the cake!
“Hands-on!”
Cooking up things is cool…
Though let’s talk about the
recipe first!

7. Containers vs Virtual Machines

8. Sample Dockerfile
# Pull the latest batch script
ENV HOME /root
COPY testblog.sh /data/bin/
COPY testblogcron /data/bin/
COPY startcron.sh /data/bin/
# Setup 755 on the scripts
RUN chmod 755 /data/bin/*.sh
# Setup Cron Job
RUN cat /data/bin/testblogcron >> /etc/crontab
# Setup Cron Log
RUN touch /var/log/testblog.log
# Define default command.
CMD ["/data/bin/startcron.sh"]

# BlogTest Dockerfile

# Source : https://bitbucket.org/kvaes/docker-testblog/
# Author : Karim Vaes
# Use Ubuntu 10.04 as a base
FROM ubuntu:10.04
# First let's do some updates!
RUN apt-get update && apt-get -y upgrade
# Install cron
RUN apt-get -y install cron
# Let's prep the directory
RUN mkdir -p /data/bin

9. Basic Docker Flow

10. What about changes & updates?

11. What makes containers lightweight?

19. Show me!
aka “Hands-on”

20. Demo : Deploy our base setup

21. Demo : Deploy our base setup
Server
Leave “nodesApi” blank
Select “Server” for “deploymentType”
Base Configuration
Setup ACL
Browse to “Add Custom Host” & retrieve
API url
Nodes
Enter API url in “nodesApi”
Select “Nodes” for “deploymentType”
Choose “2” as “nodesCount”
