Michigan IT Symposium 2017 - Container BOFJeffrey Sica
Development with Containers
Moderator: Jeffery Sica
Orchestration and Management with Containers
Moderator: Bob Killen
The Container has revolutionized how many industries and enterprises develop and deploy software and services. While the promise of containers to improve reliability, reproducibility and sharing application is helping to drive this adoption, there are still questions and concerns that are holding back broader adoption. In this BOF we will provide an opportunity for the Michigan IT community to engage with the local leaders in this area that are developing solutions and promoting the container model in their units
This BoF has been broken into two high-level topics: Development with Containers that is geared toward developers working with and implementing containerized applications, and Orchestration and Management with Containers that is geared toward sysadmins that are hosting and maintaining production-level containers. There will be an overview followed by an interactive period where the audience can ask questions of our experts and share their experiences with others. A key goal of these sessions is to understand and develop an agenda for solving questions and concerns that are holding back broader adoption.
My college ppt on topic Docker. Through this ppt, you will understand the following:- What is a container? What is Docker? Why its important for developers? and many more!
Docker is the world’s leading software container platform. Developers use Docker to eliminate “works on my machine” problems when collaborating on code with co-workers. Operators use Docker to run and manage apps side-by-side in isolated containers to get better compute density. Enterprises use Docker to build agile software delivery pipelines to ship new features faster, more securely and with confidence for both Linux and Windows Server apps.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Elevating Tactical DDD Patterns Through Object CalisthenicsDorra BARTAGUIZ
After immersing yourself in the blue book and its red counterpart, attending DDD-focused conferences, and applying tactical patterns, you're left with a crucial question: How do I ensure my design is effective? Tactical patterns within Domain-Driven Design (DDD) serve as guiding principles for creating clear and manageable domain models. However, achieving success with these patterns requires additional guidance. Interestingly, we've observed that a set of constraints initially designed for training purposes remarkably aligns with effective pattern implementation, offering a more ‘mechanical’ approach. Let's explore together how Object Calisthenics can elevate the design of your tactical DDD patterns, offering concrete help for those venturing into DDD for the first time!
Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

4. What is Docker?
An open-source project that
automates the deployment
of applications inside
software containers
5. Sounds a lot like VM to me…
VM hypervisors (such as Hyper-V, KVM, and Xen)
are all based on emulating hardware. That makes
them fat in terms of system requirements.
Containers use shared operating systems. Instead
of virtualising hardware, containers rest on top of a
single Linux instance.
6. Why do we like that?
When using containers you can leave behind the
useless 99.9% VM junk, leaving you with a small,
neat capsule containing your application.
7. I don’t need Docker
I can do all that stuff with LXC tools, rsync + some
scripts!
true on all accounts
but it's also true for apt, dpkg, rpm, yum, …
the whole point is to commoditise
to make it ridiculously easy to use
8. What is Doxford?
Docker Oxford is a place to learn about Docker
and containers.
We are developers, sysadmins and ops and
software engineers, working with containers to
build and deliver better software.
11. Docker on your machine
• Docker client - CLI you issue commands to
• Docker daemon - Service running in the
background, responsible for pulling images,
running containers and streaming input/output from/
to the client
12.
13. Images & Containers
• Image
An ordered collection of root filesystem changes -
typically a union of layered filesystems stacked on
top of each other. Images are read only.
• Container
A container is a runtime instance of a docker
image. Consists of:
- A Docker image
- Execution environment
- A standard set of instructions
14.
15. Building an image
• Dockerfile - a text document that contains all the
commands you would normally execute manually in
order to build a Docker image
17. Committing an image
If you make
changes to a
container, you
can commit those
changes by
creating a new
image from that
state!
18. Shipping an image
• Locally - you can build the image on the same
machine as you run it on. That way the image is
instantly accessible after it’s been built.
• Registry - the more scalable way to ship images is
to use a registry - it’s basically a third machine that
acts as an image store. You build the image on one
machine, push it to the registry, and pull it down to
all other machines that want to run containers from
that image.
The most famous registry is hub.docker.com
23. Docker Hack Day
• Anything Docker-related
• Submit idea + find a team (we can help you do
that)
• Join us at the Hatch on Saturday 19th September
for a day of coding
• Details on the Meetup page
24. Requests
• Docker cases in production
• Drone for continuous integration
• Anyone using Registry? Nope.
• Can you use AutoScaling with Docker?
25. Ack.
- James Bottomley explains the difference between containers
vs. VMs really well.
- Docker glossary explains everything: http://docs.docker.com/
reference/glossary/
- Matt Jaynes (@nanobeep on Twitter) provides excellent
guidance in combating complexity
26. Q&A
• What’s the benefit of using -v over committing everything to the image? —> -v
allows you to from the host share SSL certs, passwords, things you (may) want
to change independently of your container — anything you need to get out to
make the container stateless.
• You can use —format when doing docker inspect
• Production use case 1: On AWS with RDS (postgres), ElasticSearch, Nginx
using Docker Compose (a YAML file that describes links between containers)
• Production use case 2: RESTful API spawning containers for processing videos
• Can you link multiple containers? —> Yes, with Compose
• RancherOS — dockerised version of Linux
• Dokku - Heroku in a box
• Openshift - Runs SELinux
• Mesos — post article with diff Kubernetes
• If you have to log in to a container and change stuff you’re probably doing it
wrong…
• Docker newsletter is useful
27. Ideas for future talks.
• Using Docker as a provider for Vagrant
• Docker Compose, Swarm and Machine
• Docker good ideas and misconceptions
• Docker security (sharing machines, verifying images,
patching)
• Logging and monitoring
• Docker platform as a service
Please contact us if you want to give a talk on any of these
topics!
