Take the Ops out of GitOps. Architecture for a marriage between… | by Harry Panayiotou | Jan, 2021 | Medium

Architecture for a marriage between GitOps and CD This is a description of how myself and other members of the team implemented ArgoCD for Kubernetes. The difference being, we did this in a world of small teams with no capacity to manage files in git manually and with Kubernetes knowledge limited to just the DevOps team. GitOps has become really popular over the last couple…

Notifications for Argo. Notifications are very important for… | by Alexander Matyushentsev | Jan, 2021 | Argo Project

admin 5 days ago in

Notifications are an important part of the complete end-user experience but can be tricky to get right. Different organizations use different kinds of notifications services such as Slack, OpsGenie, or just good old email. There are dozens of different types of events that may need notification, so it is hard to predict all possible scenarios and optimize for all of them. Finally, every organization has…

利用 Flux2 為 Kubernetes 達成Configuration Management | by smalltown | Starbugs Weekly 星巴哥技術專欄 | Jan, 2021 | Medium

自己管理的 Kubernetes Cluster 已經十幾座了，而且會越來越多，為什麼有這麼多座呢？因為隨著組織的成長，就會開始有不同的部門，同部門內又會依照環境至少分成開發，測試以及正式三個 K8s Cluster，因此預期 K8s Cluster 的座數在未來只會增加不會減少；或許有人會想說怎麼不準備一個大 K8s Cluster 給大家一起共用就好？！但為了安全性和其他考量，最終還是決定維持多個 K8s Cluster 的模式，有興趣想要知道怎麼決定組織內該使用一座或是多座 K8s Cluster 的人可以參考 “這篇文章” 的利害分析 不同座 K8s Cluster 分別是給不同部門和環境使用，每座 K8s Cluster 一定都會有一些重複的東西需要去做設定，並讓維運人員去做後續的管理，例如 Prometheus, Ingress Controller…等，秉持著 Infrastructure as Code 的精神， 在這幾年管理 K8s Cluster 大致上可以分成三個時期： 在多年前 helm 剛被提出時，我們讓一個部門使用一個 Git Repository，在裡面透過資料夾結構安排，將不同的環境切開來，並且將 helm chart 放在 charts 的資料夾內，至於安裝套件間的相依性，雜七雜八需要注意的，就透過 makefile 和文件去補足 隨著需要管理的 K8s Cluster 越來越多，以及安裝的東西越來越複雜，所以開始研究類似 helmfile 跟 helmsman，這類型的工具有點像是在模仿 Terraform 的操作模式，並且可以把不同環境安裝時的組態都先定義好，也把 helm chart repository 都抽象化，套件之間的相依性也可以幫忙解決 但科技始終來自於惰性，雖然使用 helmfile…

Kapitan Kubernetes Challenge #1. So the other day using the kapitan.dev… | by Alessandro De Maria | Jan, 2021 |...

So the other day using the Twitter @kapitandev handler I set the following challenge Didn’t get many answers (help us! Please follow, RT and like) but I think many missed the point of the challenge. Good, because I have the right chance to talk about a hidden gem of Kapitan. “templated scripts” or canned scripts. Understandably, I only got replies from people that were fairly…

GitOps and multi-repo versioning. Multiple Git repositories/apps, one… | by Kyle Weeks | Jan, 2021 | Medium

admin 2 weeks ago in

Multiple Git repositories/apps, one Kubernetes (K8s) deployment. What do you do to streamline the development process? This time, I chose GitOps, a declarative approach where Git is the single source of truth for the current deployment state. How many replicas of app A are running? What version of app B? Just Git it. While setup went mostly smoothly, one challenge was versioning. What commit from…

If you are reading this article we assume you are already familiar with Azure Stack and Azure Stack Edge, in fact, you can always…

Introduction to GitOps with ArgoCD | by Louis Moon | Jan, 2021 | Medium

admin 3 weeks ago in

– Explains the concept of GitOps and show example of GitOps pipeline with ArgoCD. GitOps is an extension of IaC(Infrastructure as a Code) and a pattern to do Continuous Deployment for cloud native applications. It works with 1) Git repository as a source for declarative infrastructure configuration files and 2) Continuous Deployment tools for sync the configuration files with applications being served. The sync process…

Hands-on GitOps with OneDev and Kubernetes | by Robin Shen | Dec, 2020 | Medium

admin 1 month ago in

GitOps is a DevOps approach to maintain Kubernetes-based infrastructure as code in git, and operate it with git tools such as push, revert, pull request. OneDev (https://github.com/theonedev/onedev) is an open source git repository server, with built-in CI/CD integration. This tutorial explains how to set up OneDev to do GitOps in Kubernetes. Firstable we need a Kubernetes cluster. You may use an existing one, or just…
