Setting up Notifications, Alerts & Webhooks with Flux v2 by Alison DowdneyWeaveworks
Watch the recording here: https://youtu.be/cakxixc-yQk
❗️ Notifications & Alerts ⚠️
When operating a cluster, different teams may wish to receive notifications about the status of their GitOps pipelines. For example, the on-call team would receive alerts about reconciliation failures in the cluster, while the dev team may wish to be alerted when a new version of an app was deployed and if the deployment is healthy.
Webhook Receivers
The GitOps toolkit controllers are by design pull-based. In order to notify the controllers about changes in Git or Helm repositories, you can setup webhooks and trigger a cluster reconciliation every time a source changes. Using webhook receivers, you can build push-based GitOps pipelines that react to external events.
Alison Dowdney, Developer Experience Engineer at Weaveworks and CNCF Ambassador, walks through how to define a provider, an alert, git commit status, exposing the webhook receiver and defining a git repository and receiver.

Bonjour à tous,
Pour ce meetup, nous avons la chance d'être reçu dans les locaux de Richemont.
Je remercie particulièrement Cédric Georg ainsi que l'équipe de Richemont pour leur accueil.
A ce meetup DevOps, nous aurons 2 Retours d'Expérience, voici l'agenda de la soirée:
18:30 - Ouverture des portes
(il faudra donner votre nom et prénom ainsi que votre numéro de plaque d'immatriculation si vous êtes venu en voiture, c'est pour la sécurité, et oui, on ne rigole pas ici :-))
18:50 - Introduction de Matthieu et de Cédric
19:00 - Richemont et sa transformation DevOps
Richemont, fort de sa transformation digitale, a dû s'adapter afin de faire travailler ensemble, avec des outils d'automatisation et de communication, les équipes de développeurs et les équipes opérationnelles.
Squad, DevOps, Tests, Sécurité, Agile et Scrum, comment tous ces termes ont sû devenir le quotidien de Richemont en seulement quelques années.
Nous verrons comment nous avons mis cela en place, quels ont été les points positifs et négatifs de cette transformation.
19:40 - SixSq et l'automatisation du docker sur des edge points (DEMO)
Edge computing is gaining in popularity to address the explosion of data produced by IoT sensors, and the need to better manage AI both in the cloud and at the edge. To address this paradigm shift, SixSq has launched two open source projects: Nuvla for managing applications, and NuvlaBox, a cloud-in-a-box edge solution.
Using these open source projects, in this session we'll demonstrate how edge computing can now be integrated to agnostically operate containerized applications on CaaS infrastructures anywhere, using a Raspberry Pi-based platform.

Open Source Licensing: Types, Strategies and ComplianceAll Things Open
Presented by: Jeff Luszcz, ZebraCatZebra
Presented at All Things Open 2020
Abstract: Open Source powers the world, but you need to do more than use it.
In this talk we will provide background on the most common types of open source licenses, business models, security issues and the processes required to help you remain secure and in compliance. We will discuss best practices, scanning tools, remediation, customer and partner expectations around OSS compliance and how to manage OSS during events such as a product release or M&A.
Innovation at Perforce never stops. Since the last MERGE conference, there have been continual updates across the board in response to user requests. In this session, we're going to look at what's new and take a peek at what's in the works so that you can start planning to exploit them when they're available.
Continuous delivery is a powerful concept, but hard to achieve. One of the challenges is automating the setup of environments and the deployment of the Java EE applications. We have looked at and used quite some tools like for instance Chef, Puppet, Vagrant and Nolio. All tools had one thing in common: we had never used them. Why should we invest time in mastering those tools? There is a perfect alternative in Jenkins, a tool most developers are familiar with. Besides the basic Jenkins buildserver capabilities it offers quite some useful plugins like the Build Pipeline plugin. To setup environments the popular Docker project is used. Docker allows you to create containers from any application. Only some knowledge is required for the setup of the containers. The rest of the configuration is done through commands most people are quite familiar with.
n this presentation you will learn why enterprises are so excited about OpenShift, the Container Platform by Red Hat. This platform leverages open source technologies like Docker and Kubernetes, to deliver a platform ready for agile application development, while providing ops the stability they need for production deployments. In this presentation we will cover how OpenShift meets these challenges, and give you some insight in how OpenShift is working.
We Need to Talk: How Communication Helps CodeDocker, Inc.
To build a successful open source project requires more than just code. As Docker and many other household-name projects show, communication is also an essential ingredient in growing a project to greatness. This introvert-friendly talk will help you level up your development game by highlighting three tools and techniques: user research, InnerSource, and documentation. First, I'll help you apply some basic user research practices to refine your project purpose, vision, and value proposition. Then I'll talk about the role of documentation and effective storytelling in generating interest and feedback from broad development audiences. Next, I'll move on to InnerSource: what it is, how it works, and how it can improve your team's communication and collaboration habits. For this, I'll share real-world examples (including some from Zalando) of how InnerSource enabled teams to develop more effectively and efficiently. Finally, I’ll offer some examples of open-source projects (including Docker) that demonstrate how great communication leads to great software. Ideally, you’ll come away inspired to integrate more communication into your development processes.
Belarus Jenkins Meetup - Managing security in Jenkins with configuration-as-c...Oleg Nenashev
In this presentation I will show how to protect your Jenkins system from common user mistakes using Configuration-as-Code and Ownership-based security.
When you are designing a production environment security is essential. All the Docker ecosystem but in particular Docker Swarm allows us to ship our containers out of our laptop, how can we make this process safe? During my talk, I will share tips around production environment, immutability and how troubleshooting common attack as code injection with Docker. Static analysis of our images, content trust with Notary to make our journey secure.
How can we setup a cluster on the main cloud providers with VPN and node labeling to expose only a portion of our cluster? I will also show what Docker provides (Content Trust, Static Analysis) but also open source alternatives as Notary, centos/clair and Cilium.
In the end of this talk, we had a better idea around how manage Docker in production.
It’s 2021. Why are we -still- rebooting for patches? A look at Live Patching.All Things Open
Presented by: Igor Seletskiy
Presented at the All Things Open 2021
Raleigh, NC, USA
Raleigh Convention Center
Abstract: IT Teams know the drill. New security bulletins, new issues, new patches to deploy. Schedule another maintenance operation and prepare for system downtime.
There is a better way to do things. Live patching has been around in the Linux Kernel for some time now, but adoption has not been ideal so far - either because of a lack of trust in the technology or just lack of awareness - or sysadmins just enjoy interrupting their workloads or users.
Live patching consists of two aspects. First, there has to be a mechanism for function redirection in the kernel. As in many things, the kernel actually provides three different subset of tools that provide this functionality - kprobes, fprobes and Livepatching. Secondly, Live Patching relies on a set of tools to generate the actual patches to deploy, replacing the old code with new one. This is arguably the most involved part: you need to fit your new code in the proper space, you can’t overwrite other unrelated code and you need to maintain compatibility with other functions. If you change your parameter list, for example, its game over - something will break in the worst possible way.
In this talk we’ll go over issues like Consistency model, patch generation, deployment mechanisms and identify situations that are ideal candidates for live patching instead of traditional patching operations.
In this hands-on lab, you'll learn how to create containerized applications and test them in a Red Hat OpenShift development cluster. You'll quickly develop a basic containerized application, break down an application into multiple containers, and then deploy these images to container host platforms. You’ll get a feel for the different container host platforms and learn how to choose the best one for your container needs. Finally, you’ll understand what to consider and what tools are available when implementing a containerized, microservices architecture.

August OpenNTF Webinar - Git and GitHub ExplainedHoward Greenberg
When OpenNTF began in 2001, source control was little known and sharing of code via the cloud was limited. Fast forward 20 years and GitHub is the dominant sharing site and git the standard technology for source control.
In this webinar Paul Withers and Jesse Gallagher will:
Demystify git
Explain Branching
Show what makes a high quality repository
How to take advantage of GitHub’s broad functionality
Get that coveted "Verified" badge
Go from source control zero to GitHub hero!
Best practices with git - The essentials you should know about git to use if efficiently
Workshop by Otto Kekäläinen at OpenFest 7.11.2015, Sofia, Bulagaria.
This 68 slides beast surely has something new even for seasoned git developers!
Source Control is a must. As a consulting shop, we use our client’s source control tool when necessary and even setup TFS for some clients. When given the choice, we use Git. This session answers the question “Why Git?” Topics include comparing Git/GitHub, TFS, and Subversion along with a walk through of project setup to show how we get the most out of Git.
On the past Thursday, 10 November, the training Workshop : ‘’Git & GitHub’’ took place, given by our colleague Alfonso Rodríguez, django developer, at IES CAMAS.
Encripta como si todos te espiaran y baila como si nadie te viera!CloudNativeElSalvado
Hoy en día existen una serie de medidas con las que debe contar todo proyecto de software para ser seguro tanto para empresas y consumidores. En esta sesión nos apoyaremos del proyecto OWASP para poder alcanzar una seguridad optima tanto a nivel funcional como técnico y aprender a generar un interés en estas prácticas para los programadores y directivos.
“Everything as Code” se ha convertido en el status quo entre las organizaciones líderes que adoptan prácticas de DevOps y SRE y, sin embargo, el monitoreo y la observabilidad se han quedado rezagados con respecto a los avances realizados en la entrega de aplicaciones e infraestructura.
El monitoreo como código adopta el mismo enfoque que la infraestructura como código, con el que está estrechamente relacionado: tu administras el monitoreo de la misma manera que lo haces con las aplicaciones, los servidores u otros componentes de la infraestructura. En esta charla/demo veremos uno de tantos casos de uso y para ello utilizaremos Terraform y New Relic
Istio Kubernetes es una red (o malla) de servicio que proporciona gestión de tráfico, aplicación de políticas de complimiento y recolección de métricas. Una malla de servicios (“Service mesh”) es una capa de infraestructura dedicada para gestionar la comunicación de servicio a servicio. Esto es lo que veremos esta sesión, acompáñanos y aprendamos juntos con Rafael Contreras.

Durante esta charla presentaremos las dos comunidades y discutiremos la idea de tender un puente entre nuestras dos comunidades, CNCF y HL.
Además de ser una charla, también queremos que sea una sesión de trabajo para discutir cómo podríamos trabajar juntos, encontrar proyectos juntos, apoyarnos con el tema de capa de infraestructura, considerar mentoría de proyectos Hyperledger, establecer confianza entre miembros, y encontrar apoyo local para crear pasantías pagadas y virtuales.
Desarrollar e Implementar CI/CD con Github Actions - oct. 28CloudNativeElSalvado
Github Actions, tiene un concepto de workflow (flujo de trabajo), el cual es el encargado de todo nuestro proceso (o Pipeline) que puede ser configurable, y en donde se puede especificar que se analicen diferentes aspectos del proyecto, para evitar algún error en el proceso. En esta sesión veremos ¿Qué es la Integración y Distribución Continua de software CI/CD? ¿Cómo es el CI/CD con Github Actions? demos y más...
Evento enfocado en presentar la iniciativa que busca impulsar el desarrollo de los jóvenes y profesionales de El Salvador en las tecnologías de Cloud Native.

0x01 - Newton's Third Law: Static vs. Dynamic AbusersOWASP Beja
f you offer a service on the web, odds are that someone will abuse it. Be it an API, a SaaS, a PaaS, or even a static website, someone somewhere will try to figure out a way to use it to their own needs. In this talk we'll compare measures that are effective against static attackers and how to battle a dynamic attacker who adapts to your counter-measures.

6. ¿Qué es Git?
Es un software open source para control de versiones.
7. ¿Cómo funciona?
Los repositorios de Git están basado en branches (ramas). Se puede
visualizar como un árbol central donde se van creando diferentes ramas
que sostienen código fuente.
Git lleva un histórico de TODOS los cambios que se han hecho en el
código, además de poder regresar a versiones anteriores en caso de existir
errores.
Se pueden utilizar repositorios locales o subir tu código a repositorios en
internet.
Existen muchas alternativas para subir tu código, entre las más conocidas
son:
● Github.
● Gitlab.
● Bitbucket.
8. ¿Por qué es importante?
Existen muchos beneficios para utilizar Git, entre algunos de ellos
están:
1. Permite llevar un tracking de los cambios.
2. Puedo recuperar archivos eliminados, código eliminado,
código modificado, etc.
3. Puedo hacer pruebas de código sin alterar el funcional
actual.
4. Puedo trabajar fácilmente en equipo, cada quien con su
rama.
5. Es posible observar el nivel de colaboración de cada
miembro del equipo.
9. Comandos básicos
1. Git clone. Clonar repositorio remoto en
nuestra local.
2. Git init. Iniciar repositorio.
3. Git status. Ver los cambios actuales
4. Git add. Añadir los cambios al stage
5. Git commit -m. Guardar los cambios con
un mensaje
6. Git push origin main. Enviar cambios a
repositorio remoto.
7. Git pull origin main. Descargar cambios
del repositorio remoto
11. ¿Teamwork?
Bien, llegamos a la parte más importante.
El trabajo en equipo es MUY importante en el desarrollo de
software y hacerlo de la mejor manera es primordial.
La tecnología de Git, nos permite organizar y desarrollar
código colaborativo gracias a su lógica de ramas y porque es
posible mezclarlas (merges)
14. ¿Qué es un despliegue?
Un deployment o despliegue se refiere a publicar tu proyecto
en servidores y que pueda ser accedido fuera de tu red
privada, mayormente en internet.
Actualmente, todo el trabajo de configuración de servidores y
networking te lo pueden hacer PaaS (Platform as a Service)
como:
● Google Cloud.
● Digital Ocean.
● AWS.
● Vercel.
● Heroku.
● Netlify.
● Azure.
Así que puedes ahorrarte mucho dinero y tiempo en no
mantener tu servidor.
15. ¿Qué se necesita?
Para hacer un despliegue necesitas:
1. Hosting, VPS o servidor dedicado.
2. IP Pública.
3. Dominio.
4. Infraestructura diseñada (recomendable)
5. Aplicación y/o base de datos a desplegar.
6. Repositorio de Git (recomendable)
7. Conocimientos de línea de comandos (recomendable)
8. Conocimientos de networking (recomendable)
18. Mostrar tu trabajo.
¿Por qué necesito tener un portafolio?
1. Exhibe tu trabajo
2. Carta de presentación en tu CV y redes sociales
3. Muestra tu actividad
4. Muestra tus conocimientos
5. Muestra tu metodología de trabajo y buenas prácticas.

19. Mostrar tu trabajo.
Repositorios como Github, Gitlab, Bitbucket o el de tu
preferencia, son elementos esenciales actualmente a la hora
de buscar empleo, porque permite que los reclutadores y
empresas observen el trabajo que has realizado y si puedes
ser un buen fit dentro de su equipo de ingeniería.
Además, de cómo lo vimos anteriormente, el manejar git es
sumamente importante para trabajar en equipos de desarrollo
ya que permite mayor agilidad y reduce errores en muchos
casos.
