Building Distributed Systems without Docker, Using Docker Plumbing Projects -...Patrick Chanezon
Docker provides an integrated and opinionated toolset to build, ship and run distributed applications. Over the past year, the Docker codebase has been refactored extensively to extract infrastructure plumbing components that can be used independently, following the UNIX philosophy of small tools doing one thing well: runC, containerd, swarmkit, hyperkit, vpnkit, datakit and the newly introduced InfraKit.
This talk will give an overview of these tools and how you can use them to build your own distributed systems without Docker.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

2. Summary
Virtual machines VS containers
Containers
What is Docker ?
LXC vs Docker
Docker basic concepts
The Open Container Initiative (OCI)
Runtime containers
OCI Containers images
Write a Docker File
Build an image with Docker
Docker Compose
Images Registry
Docker Engine
Run a container with Docker
3. Virtual Machines VS Containers
One host OS
Smaller, faster, easy to scale.
Many guest OS
Bigger, slower, harder to
scale.
4. Containers
See containers like an app in an isolated box
Resources managed: size, cpu, memory, file system, network, etc.
Standard based on LXC (Linux Container) and Windows Container
Kernel namespaces (ipc, uts, mount, pid, network, user) : what you can see
Apparmor, SELinux (security)
Cgroups: limits what you can use and isolates resource usage
chroots
Solve problem « it’s work on my computer ! »
Enables automatization, CI/CD, Scaling
Cost optimization
Microservices approach
5. What is Docker ?
Version 1.0 in 2014
Goal: Friendly and easy use of LXC containers
Tools for developers to build containers
Tools for operators to run containers
Define new standard of image containers, image distribution, containers
runtime
Container != Docker
Docker Engine = Client/Server architecture
7. Docker basic concepts
Image: Static, persisted container image
Container: Image-instance running an app process
Registry: Stores many static images
8. The Open Container Initiative
Formed in 2015 by Docker
The OCI define industry standards around container image formats and runtime
Docker image format has become OCI Image Specification
Docker, BuildKit, Kaniko, Buildah
Docker Registry protocol has become OCI Distribution Spec
Docker runtime has become OCI Runtime Specification (CRI)
Low-level and high-level runtime containers
runc, Kata containers, gVisor, Firecracker
Podman, containerd, rkt, cri-o
Container Network Interface (CNI): Defines how connectivity among containers
10. OCI Containers Images
A container image is a static representation of the app and its configuration
To run the app, an image is instantiated to create a container
To build container images with Docker: write a Dockerfile
Container images are versioned
OCI images are layers assembly (see them like pieces of file system)
Layers are mounted together by an union filesystem (overlayFS)
Layers are immutables (copy-on-write)
11. Dockerfile
A text document that contains commands to
assemble an image
Must begin with a FROM instruction
Build cache mecanism
Commands :
docker build –t image/name:1.0 .
docker history image/name:1.0
Nodejs app Dockerfile example
13. Docker use a cache system with a hash for each step
Each hash identify the file system of an intermediate container
docker history to see each layers of the image
Docker build image
Docker history
Docker build
14. Docker Compose
Tool for defining and running multi-
container Docker apps
YAML file to configure app services
Used for devs and automated testing
environments, not production
Example with Wordpress + Mysql
Commands:
docker-compose run
docker-compose up
docker-compose stop
docker-compose config
15. Images Registry
Images are stored in a Registry
Docker Registry HTTP API V2 protocol
OCI Distribution specification
Docker public registry : Docker Hub (hub.docker.com)
Docker Hub contains all officials images (ubuntu, mysql, pyton, java, etc.)
Docker commands :
docker images
docker pull
docker login my.registry.url
docker tag image/name:1.0 my.registry.url/image/name:1.0
docker push
16. Docker Engine
Complete Tools box
Daemon controlled by REST API
CLI Docker client
Manages containers, images, builds,
etc.
Enterprise edition with more features
17. Run a container with Docker
A container image becomes a container when « docker run » is executed
Commands:
Run container: docker run -d -p 27017:27017 --name mongodb mongo:latest
Connect to container: docker exec -it mongodb bash
Start/Stop/delete container: docker start/stop/rm mongodb
Show container logs: docker logs mongodb
List containers: docker ps
VMs :
VMs help reduce expenses. Instead of running an application on a single server, a virtual machine enables utilizing one physical resource to do the job of many.
Containers:
Containers help reduce expenses as well and they are remarkably lightweight and fast to launch. Because of their small size, you can quickly scale in and out of containers
