System level tuning for Docker containers
We are doing performance engineering on a stack which consists of Nginx,Tomcat, Node JS, Jboss Fuse & other components. All of these components are containerized. We are using Docker for containerization. Kubernetes is used for managing the docker cluster.
Is system level tuning like sysctl,ulimits … still applicable at the container level?
Can I have different sysctl settings for different containers as different type of containers might run on the same physical host ?
