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?

  • docker-compose: links option not working
  • Docker api: push an image to docker hub private repository
  • Can't pull image from docker repo
  • Docker remote api pull from Docker hub private registry
  • Containerization of OpenStack services with Kubernetes?
  • Not getting the IP address of the docker container from node.js code when run the container with port forwarding
  • Can I have different sysctl settings for different containers as different type of containers might run on the same physical host ?
