Selamlar, Bu gün k8s için neden secretler’i senkronize eden bir operator yazdığımı, nasıl yazdığımı anlatmaya çalışacağım. Kubernetes’de bazı durumlarda secretleri veya ConfigMap’leri başka namespace’lerde de kullanmak isteyebiliyoruz. Kubernetes’de secretler ve ConfigMap’ler namespace bazlı olduğu için farklı bir namespace’den kullanamıyoruz. Kullanmak icin ise secreti veya configmap’i kullanacağımız namespace e kopyalamamız lazım. Birden fazla namespace veya secret olduğunda bu iş baya bir zor olabiliyor. Bende bunun için…

최근 많은 기업들이 어플리케이션 아키텍처로서, 기존 모노리스 아키텍처 방식을 버리고 마이크로 서비스 아키텍처를 도입하면서 자연스럽게 소프트웨어의 운영 방식에도 많은 변화가 일어났습니다. 수많은 서비스들을 빠른 시간내에 배포하는 작업이 빈번히 요구되는 운영 환경 조건들을 충족해줄 수 있는 컨테이너 기술들이 인기가 많아짐에 따라 자연스레 분산 컨테이너 환경을 자동화할 수 있도록 돕는 대표적 오케스트레이션 툴인 Kubernetes를 점차 활용하고 있는 추세입니다. Kubernetes의 스케줄링, 스케일링, 자가 회복, 리소스 관리 등 어플리케이션…

Deploying operator webhooks with OLM | by Srutha K | Oct, 2020 | Medium

admin 2 months ago in

Co-authored by Adam Roberts The Operator Lifecycle Manager (OLM) extends Kubernetes to provide a declarative way to install, manage, and upgrade Operators on a cluster. Using OLM, we can create a catalog source that holds multiple operators that can be made available for installation from the Operator Hub. We will be using this approach (of many) of OLM. In depth understanding on OLM can be…

The above yamls represent VirtualService and Task custom resources. The…

Simplifying Bundled Kubernetes Resource Deployments | by Ian Muge | Sep, 2020 | Medium

admin 3 months ago in

I recently had a discussion on how to simplify deployment of common bundled modules so as to enable developers to roll out resources and services on test environments with similar base requirements all while encapsulating the complexity of the setup. All this in an attempt to left-shift deployment on test infrastructure, all while empowering the developers to have slight insight on the architecture underlying and…
