Doker jest projektem opensource pomagającym zautomatyzować wdrażanie i uruchamianie aplikacji przy wykorzystaniu kontenerów linuksowych. Dzięki swojej wydajności oraz praktycznie zerowemu narzutowi jest coraz częściej wybierany jako alternatywa dla tradycyjnych rozwiązań wirtualizacji systemów.
Podczas tego wykładu dowiecie się czym jest docker, jak nim zarządzać oraz jak stworzyć swoje pierwsze kontenery aplikacyjne.

EuroPython 2014 - How we switched our 800+ projects from Apache to uWSGIMax Tepkeev
During the last 7 years the company I am working for developed more than 800 projects in PHP and Python. All this time we were using Apache+nginx for hosting this projects. In this talk I will explain why we decided to switch all our projects from Apache+nginx to uWSGI+nginx and how we did that.

Journey to Microservice architecture via Amazon LambdaAxilis
Microservices are one of the latest trends in architecture design.
Made popular by the introduction of Amazon Lambda, Google Cloud Functions and Azure Functions. They seem to offer a way to structure code as a set of independent services that interact together to work as one, making each part simpler and offering an easy way to scale up. But just as every other technology they bring their own set of challenges.
Join us on lessons we learned while converting simple application to work on Lambda.
Small, Simple, and Secure: Alpine Linux under the MicroscopeDocker, Inc.
Alpine Linux is a distro that has become popular for Docker images. Why do we need another distro? Why does Alpine matter? How does it differ from other distros?
In this talk, we'll answer all these questions – and a few more.
Multiple django applications on a single server with nginxroskakori
This talk explains how to install and setup multiple Django applications on a single server.
The general principle is to setup a systend service for each application that runs in nginx and gunicorn on Ubunto 20 LTS. This results in a lightweight installation that requires only a few and small configuration files that is well integrated in the existing tool chain around systemd.

Testing applications with traffic control in containers / Alban Crequy (Kinvolk)Ontico
Testing applications is important, as shows the rise of continuous integration and automated testing. In this talk, I will focus on one area of testing that is difficult to automate: poor network connectivity. Developers usually work within reliable networking conditions so they might not notice issues that arise in other networking conditions. I will give examples of software that would benefit from test scenarios with varying connectivity. I will explain how traffic control on Linux can help to simulate various network connectivity. Finally, I will run a demo showing how an application running in Kubernetes behaves when changing network parameters.

Streamline your development environment with dockerGiacomo Bagnoli
These days applications are getting more and more complex. It's becoming quite
difficult to keep track of all the different components an application needs in order to
function (a database, a message queueing system, a web server, a document
store, a search engine, you name it.). How many times we heard 'it worked on my
machine'?. In this talk we are going to explore Docker, what it is, how it works
and how much it can benefit in keeping the development environment consistent.
We are going to talk about Dockerfiles, best practices, tools like fig and vagrant,
and finally show an example of how it applies to a ruby on rails
application.

Additionally to showing the basics, it will introduce helpful libraries available for the JVM and how they can be used together with Docker to create secure, scalable and maintainable cloud setups for your applications.
Docker jest wspaniałą technologią. Przy pomocy Dockera w prosty sposób możemy rozwiązać jeden problem, a na jego miejsce stworzyć dwa inne, nowe, bardziej skomplikowane... Co jest powodem takiego stanu rzeczy? Czy przyczyną jest architektura Dockera? Brak zrozumienia? A może coś więcej?

Connector Corner: Automate dynamic content and events by pushing a buttonDianaGray10
Here is something new! In our next Connector Corner webinar, we will demonstrate how you can use a single workflow to:
Create a campaign using Mailchimp with merge tags/fields
Send an interactive Slack channel message (using buttons)
Have the message received by managers and peers along with a test email for review
But there’s more:
In a second workflow supporting the same use case, you’ll see:

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
