쿠린이 운영자 입장에서 느낀 kubernetes POD와 VM 차이점을 정리해 보았습니다. POD는 VM, OS 인듯 아닌듯 싶습니다. 정답은 아마 단일 Application Process 이겠죠. 접속 — ssh vs exec kube POD는 ssh가 아닌 exec 를 사용해서 접속(?) 합니다. 현재 POD 내역 POD에 접속해 보겠습니다. POD 접속은 sshd 데몬이 아니라 위와 같이 원격 POD에 bash process를 실행(exec) 합니다. (명령어가 exec(execute) — bash 입니다.) bash를 실행하므로 ssh 접속한 것과…

Also, there are scenarios where the user may want to limit the resources to be given to containers. In this post we will discuss such mechanisms. Resource Requests allow the user to define…

Pods and Containers. Consider two different web sites… | by Chethana Dhavaji | May, 2021 | Medium

Consider two different web sites deployed in pods as follows: The first web site is responsible for serving static files (content that doesn’t change often), e.g., HTML files, images, JavaScript libraries, etc. This site is deployed in a single pod consisting of two containers. The first container contains the web server, and the second container is responsible for retrieving a copy of the static files…

Kubernetes — Delete All Pods Evicted State | by Maciej | Apr, 2021 | Medium

admin 2 months ago in

In K8s sometimes when we run pods, due to lack of resources like memory or CPU or some application error pods get evicted. In this case Kubernetes will try restart these evicted pods but , if there are still no resources left or the application has any errors, the pod will still be in evicted state. Definitely yes, when we have many evicted pod in…
