GitOps w/argocd
This document summarizes GitOps and the benefits of using GitOps for continuous delivery and deployment. It discusses how GitOps allows for simplified continuous delivery through using Git as a single source of truth, which can enhance productivity and experience while also increasing stability. Rollbacks are easy if issues arise by reverting commits in Git. Additional benefits include reliability, consistency, security, and auditability of changes. The document also provides an overview of ArgoCD, an open source GitOps tool for continuous delivery on Kubernetes, and its architecture.
Kubernetes GitOps featuring GitHub, Kustomize and ArgoCD
A brief dissertation about using GitOps paradigm to operate an application on multiple Kubernetes environments thanks to GitHub, ArgoCD and Kustomize. A talk about this matters has been taken at the event #CloudConf2020
Gitops: the kubernetes way
GitOps è un nuovo metodo di CD che utilizza Git come unica fonte di verità per le applicazioni e per l'infrastruttura (declarative infrastructure/infrastructure as code), fornendo sia il controllo delle revisioni che il controllo delle modifiche. In questo talk vedremo come implementare workflow di CI/CD Gitops basati su Kubernetes, dalla teoria alla pratica passando in rassegna i principali strumenti oggi a disposizione come ArgoCD, Flux (aka Gitops engine) e JenkinsX
Intro to GitOps & Flux.pdf
The document provides an introduction to GitOps and Flux. It discusses what GitOps is, how it utilizes version control as a single source of truth for continuous delivery. It then summarizes what Flux is and its key components like the source, kustomize, helm and notification controllers. The document highlights benefits of Flux like reducing developer burden and being extensible. It also briefly mentions new Flux features like OCI support and related tools like the terraform controller, flamingo and Weave GitOps.

CI:CD in Lightspeed with kubernetes and argo cd
Enterprises have benefited greatly from the elastic scalability and multi-region availability by moving to AWS, but the fundamental deployment model remains the same.
At Intuit, we have adopted k8s as our new saas platform and re-invented our CI/CD pipeline to take full advantage of k8s. In this presentation, we will discuss our journey from Spinnaker to Argo CD.
1. Reduce CI/CD time from 60 minutes to 10 minutes.
2. Reduce production release (or rollback) from 10 minutes to 2 minutes.
3. Enable concurrent deployment using spinnaker and argo cd as HA/DR to safely adopt the new platform with no downtime.
4. Be compatible with the existing application monitoring toolset.

What's New for GitLab CI/CD February 2020
The document summarizes new features and enhancements to GitLab's CI/CD capabilities between November 2019 and January 2020. Key updates include associating milestones with releases, adding an environments dashboard to pipelines, enabling squash and merge for merge trains, and collecting evidence for releases. Planned highlights for February 2020 focus on package management, release management, and automated testing capabilities.
GitHub Actions in action
GitHub Actions is an automation platform for GitHub repositories that allows users to build workflows to automate software tasks. It was introduced in 2019 and is based on Azure Pipelines. Workflows are configured using YAML files and can be triggered by events like push commits, pull requests, or scheduled times. Actions, which are reusable code components, can be used in workflows and are sourced from the GitHub marketplace or created by users. GitHub Actions is free for public repositories and offers paid plans for private repositories.
GitOps for Helm Users by Scott Rigby
Watch the recording here: https://youtu.be/0KmqEp4VxSQ
Welcome Helm users! CNCF Flux has a best-in-class way to use Helm according to GitOps principles. For you, that means improved security, reliability, and velocity - no more being on the pager on the weekends or having painful troubleshooting or rollback when things go wrong. Built on Kubernetes controller-runtime, Flux’s Helm Controller is an example of a mature software agent that uses Helm’s SDK to full effect.
Flux’s biggest addition to Helm is a structured declaration layer for your releases that automatically gets reconciled to your cluster based on your configured rules:
⭐️ The Helm client commands let you imperatively do things
⭐️ Flux Helm Custom Resources let you declare what you want the Helm SDK to do automatically
During this session, Scott Rigby, Developer Experience Engineer at Weaveworks and Flux & Helm Maintainer, will take you on a tour of Flux’s Helm Controller, share the additional benefits Flux adds to Helm and then walk through a live demo of how to manage helm releases using Flux.
If you want to follow along with Scott’s demo, here are a couple of resources to help you prepare ahead of time:

The journey to GitOps
How to automate much of the process of Kubernetes releases and deployments by using git as a source of truth.
Continuous Lifecycle London 2018 Event Keynote
Today it’s all about delivering velocity without compromising on quality, yet it’s becoming increasingly difficult for organisations to keep up with the challenges of current release management and traditional operations. The demand for developers to own the end-to-end delivery, including operational ownership, is increasing. A “you build it, you own it” development process requires tools that developers know and understand. So I’d like to introduce “GitOps”- an agile software lifecycle for modern applications.
In this session, I will discuss these industry challenges, including current CICD trends and how they’re converging with operations and monitoring. I’ll also illustrate the GitOps model, identify best practices and tools to use, and explain how you can benefit from adopting this methodology inherited from best practices going back 10-15 years.
Git ops: Git based application deployment patterns for Kubernetes
Shahidh talks about various patterns revolving around GitOps (Git + Devops) for applications deployment onto Kubernetes and introduces Gitkube (https://github.com/hasura/gitkube) as a tool to do GitOps.

GitOps: Git come unica fonte di verità per applicazioni e infrastruttura
GitOps è un nuovo metodo di CD che utilizza Git come unica fonte di verità per le applicazioni e per l'infrastruttura (declarative infrastructure / infrastructure as code), fornendo sia il controllo delle revisioni che il controllo delle modifiche. In questo talk vedremo i concetti alla base di CI/CD, ovvero Continuous Integration e Continuous Deployment (o anche Continuous Delivery), pratiche nello sviluppo software che permettono ai team di creare dei progetti collaborativi in modo rapido, efficiente e idealmente con meno errori. Infine vedremo come implementare un flusso di lavoro GitOps usando Github actions e ArgoCD.
gitopsthekubernetesway-201026090439.pdf
GitOps is a way of implementing continuous deployment for cloud native applications using Kubernetes. It focuses on a developer-centric experience by using tools like Git and continuous deployment that developers are already familiar with. GitOps uses Git as the single source of truth for infrastructure configuration and changes. It has four main principles: the system is described declaratively, Git is the single source of truth, changes can be automatically applied, and the system is continuously validated and improved. Common GitOps operators that facilitate continuous delivery include Flux, Argo CD, and Jenkins X. The GitOps model uses a pull-based deployment approach rather than pushing changes, improving security, observability, and productivity.

Whitepaper automating kuberneteswithgitops 1
GitOps is a method for automating Kubernetes using Git as the single source of truth. It treats infrastructure as code, keeping definitions of the desired cluster state alongside application code in Git. When changes are merged, automation applies them to Kubernetes. Software agents ensure the actual cluster state matches what's defined in Git. This provides security, speed, reliability and easier compliance through the immutable, auditable history in Git.

This document discusses version control and a trunk-based approach using Visual Studio Team Services (VSTS). It begins with an overview of VSTS and its key functional areas. The document then covers topics like version control, Git, branching, merging, pull requests and code reviews. It proposes exercises for practicing these concepts using both command line Git and the Visual Studio IDE. The trunk-based approach is introduced as an alternative to feature branching where developers collaborate on a single branch.

Distributed Proxies have opened the floodgates for Service Meshes to provide substantial value at the Application Networking Layer, but early adopters of Service Meshes are often overwhelmed by operational complexities. How do you ensure that the proxy is distributed everywhere your software runs? How do you safely upgrade or roll back all those proxies? How can you ensure that your network config is correct - without pushing it to production and risking an outage? Following the GitOps Principles is key to simplifying Service Mesh Operations. Defining the entire service mesh declaratively - be it installation, proxy injection, or configuration - provides a mechanism to safely manage the complexities of a service mesh. Continuously reconciling declarative config with the latest service mesh release keeps you from being caught off-guard by CVEs. Progressive Delivery tools enable seamless movement from one version of a service mesh to another - and back - with minimal impact to traffic.
Webinar: End to End Security & Operations with Chainguard and Weave GitOps
One of the key values of GitOps relies on its fully declarative single source of truth in Git for the desired state of your entire system – configuration that continuously reconciles with the runtime of the system.
Validating committer identity in your Git repository is a critical component towards a secure GitOps solution. Although basic capabilities are provided by Git service providers, more granular controls for governance and compliance are a requirement to satisfy most enterprise grade implementations.
How do you keep that end to end process secure, from Git to Runtime?
Join Weaveworks and Chainguard for a live webinar where we will look at how Chainguard Enforce for Git together with Weave GitOps Enterprise Policy Engine allows you to secure your end to end GitOps workflows, from Git to Runtime.
You will learn how to:
- Use Chainguard Enforce for Git to ensure only authorized GitOps tooling can modify your desired state.
- Provide a secure identity to Weave GitOps Enterprise for all Git operations.
- Use Weave GitOps Policy Engine to guarantee compliance on admission.

Cloud Native Apps with GitOps
GitOps provides a way for organizations to adopt continuous delivery practices using cloud native technologies like Kubernetes and Docker. It advocates storing all infrastructure configurations and code in a Git repository to enable automated deployment and management of applications. Weaveworks adopted GitOps and was able to recover from a complete system failure in just 45 minutes by having their entire system defined as code. GitOps follows the principles of continuous delivery and observability by integrating deployment pipelines, monitoring, and security policies to drive faster, more reliable software releases.

Understanding the GitOps Workflow and CICD Pipeline - What It Is, Why It Matt...
Travelio Tech Talks 2022 presentation
The recommended workflow for implementing GitOps with Kubernetes manifests is known as trunk-based development. This method defines one branch as the "trunk" and carries out development on each environment in a different short-lived branch. When development is complete for that environment, the developer creates a pull request for the branch to the trunk. Developers can also create a fork to work on an environment, and then create a branch to merge the fork into the trunk.
Once the proper approvals are done, the pull request (or the branch from the fork) gets merged into the trunk. The branch for that feature is deleted, keeping your branches to a minimum. Trunk-based development trades branches for directories.
You can think of the trunk as a "main" or primary branch. production and prod are popular names for the trunk branch.
Trunk-based development came about to enable continuous integration and continuous delivery by supplying a development model focused on the fast delivery of changes to applications. But this model also works for GitOps repositories because it keeps things simple and more in tune with how Kustomize and Helm work. When you record deltas between environments, you can clearly see what changes will be merged into the trunk. You won’t have to cherry-pick nearly as often, and you’ll have the confidence that what is in your Git repository is what is actually going into your environment. This is what you want in a GitOps workflow.
Free GitOps Workshop (with Intro to Kubernetes & GitOps)

In this info-packed and hands-on workshop we covered:
Introduction to Kubernetes & GitOps talk:
We covered the most popular path that has brought success to many users already - GitOps as a natural evolution of Kubernetes. We'll give an overview of how you can benefit from Kubernetes and GitOps: greater security, reliability, velocity and more. Importantly, we cover definitions and principles standardized by the CNCF's OpenGitOps group and what it means for you.
Get Started with GitOps:
You'll have GitOps up and running in about 30 mins using our free and open source tools! We'll give a brief vision of where you want to be with those security, reliability, and velocity benefits, and then we'll support you while go through the getting started steps. During the workshop, you'll also experience in action and see demos for:
- an opinionated repo structure to minimize decision fatigue
- disaster recovery using GitOps
- Helm charts example
- Multi-cluster example
- all with free and open source tools mostly in the CNCF (eg. Flux and Helm).

A review on techniques and modelling methodologies used for checking electrom...
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.
CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECT
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
