WHAT’S THE PROBLEM?
Organized by the Community, for the Community.
DEVOPS CHALLENGES
• Local environment setups are getting more complex• Environment differences allow for bugs in applications• Manual setup it too complex and time consuming• Human error• Scalability issues on prem• Inability to reproduce production environment locally for
debugging• Inability to easily sync all Sitecore environments• Lack of QA and other types of reproducibility

WHAT ARE “CONTAINERS”?

BEFORE CONTAINER STANDARDS
Organized by the Community, for the Community.
SHIPPING CONTAINERS INVENTED
https://en.wikipedia.org/wiki/Malcom_McLean
In 1956, most cargo was loaded and unloaded by hand. Hand-‐loading a ship cost $5.86 a ton.
Malcom McLean born in 1913 developed the modern intermodal shipping container, which revolutionized transport and international trade.
McLean knew "A ship earns money only when she's at sea," and based his business on that efficiency.
Using containers, it cost only 16 cents a ton, a 39-‐fold savings. Containerization also greatly reduced the time to load and unload ships, improving reliability.

CONTAINER != VM
• VM’s– Full instances of the entire OS– Not easily multi-‐instanced ~SysPrep
• Containers– Layered elements of the OS + Components– Easily Duplicated, Start/Stop– Lightweight OS (Tiny Core Linux & Windows Server Core)
Organized by the Community, for the Community.
HOW TINY IS TINY?
• ~24MB download! Whaaaat?!• Runs completely from RAM• Minimal Requirements:
– 46MB of RAM– i486DX CPU (introduced in 1989, 50MHz, 8KB cache)
• Recommended Requirements:– 128MB+ of RAM– Pentium 2 CPU

SERVER CORE REQUIREMENTS
• Minimum Requirement:– 256-‐512MB of RAM– 1GHz (x86) or 1.4Ghz (x64)CPU
• Recommended– 512MB+– 2GHz+ CPU

CONTAINER COMPARISON
• Immutable infrastructure!• Fast startup (lightning fast!)• Portable & light-‐weight• A unit of deployment• Ease of creation• Each container can become a portion of the entire app
– May have multiple containers that make up one or more than one app
Organized by the Community, for the Community.
WHY CONTAINERS?
Developers
Enable ‘write-‐once, run-‐anywhere’ appsEnables microservicearchitecturesGreat for dev/test of apps and services (thousands available from Docker)Reproducibility
Operations
Portability, Portability, PortabilityStandardized development, QA, and prod environmentsAbstract differences in OS distributions and underlying infrastructureEasily scale-‐up and scale-‐down in response to changing business needs

COMMON QUESTIONS
Organized by the Community, for the Community.
1. Docker client versus host– Docker client is a command line interface (CLI) Docker– Docker host is a Linux/Windows VM running Docker daemon
2. Docker Linux and Windows hosts – You can only create the same container as the underlying host VM -‐ Linux host = Linux containers
3. Docker Image vs Docker Container– Image = The definition – literally a single file [My Website]– Container – An instance of an image [3 instances of My Website]
4. Cloud Registry Service and Public Image Repos– Unlimited public repos, one free private or buy private repos– 50,000+ images -‐Wordpress, Nginx, Redis, MySQL, Logstash, and your images!– Docker Trusted Registry –Dedicated registry application deployable on-‐premiseor direct from Azure

5COMMON DOCKER QUESTIONS
replace update5. Deployments replace instead of update
“Immutable infrastructure”
Update Website
Update your app using Web Deploy or CI/CD
Replace Docker
Replace running containers using CI/CD, Don’t update the old
container

DOCKER COMPOSE EXAMPLE
Organized by the Community, for the Community.
DOCKER SWARM
• Adds a collection of virtual machines into one logical cluster.
• Same Docker API• Elect a leader to receive commands and send to cluster• Scheduler
– Constraints – set a label on a VM/Node so matching containers use that VM (ex: region=us-‐west)
– Affinities – Filters for labels, image, containers – ex: -‐e affinity:container==frontend)
• Various Strategies
Organized by the Community, for the Community.
WRAPPING UP
• Containers Ease Development & Ops• Force a conversation of scalable design• Ease of movement (On Prem, AWS, Azure)• Immutable Infrastructure• Use Docker Hub repositories for base images• Run Solr and Mongo in containers• Run Sitecore in containers (coming soon) Really soon!
