Memory LIMIT and REQUEST in Containers and JVM

• Do you run a JVM inside a container on Kubernetes (or maybe OpenShift)?
• Do you struggle with REQUEST and LIMIT parameters?
• Do you know the impact of those parameters on your JVM?
• Have you met OOM Killer?

Hope you will find answers to these questions in this example-based article.

OSS vs Cloud

This is a list of resources about OSS vs Cloud.

Overview

The resources here highlight the trend of Cloud vendors picking up popular OSS projects and providing managed services to increase their margin and opportunity. In the majority of cases without contributing back to the OSS development itself. COSS companies formed by the creators of these OSS projects are fighting a new reality in which building a business around OSS becomes even more difficult.

OSS sustainability is potentially being set back by the unlawful practices of Cloud giants.

Notice

This script is no longer required with Docker for Mac which includes an option to run Docker at startup and doesn't use docker-machine to administer the local Docker engine.

Requirements

• Docker Machine + Docker
• curl
• A Virtualbox-driven Docker Machine called "default" docker-machine create --driver virtualbox default (this is the default with Docker toolkit).
