###Environment tested

All tests are performed in a cluster of 2 nodes of SoftLayer machines.

###Hosts SoftLayer Public CCIs 1 master: 8 CPU / 16 GB RAM 2 slaves: 8 CPU / 16 GB RAM Ubuntu 14.04 LTS 64 bits Kernel: Linux 3.19.0-31-generic #36~14.04.1-Ubuntu SMP Thu Oct 8 10:21:08 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

###Docker version: Client: Version: 1.9.0 API version: 1.21 Go version: go1.4.2 Git commit: 76d6bc9 Built: Tue Nov 3 17:43:42 UTC 2015 OS/Arch: linux/amd64

Server: Version: 1.9.0 API version: 1.21 Go version: go1.4.2 Git commit: 76d6bc9 Built: Tue Nov 3 17:43:42 UTC 2015 OS/Arch: linux/amd64

###Mesos: version 0.25.0

###Kubernetes: 1.1 branch with additional tuning from Hai: https://github.com/huang195/kubernetes, packed as a docker image (linsun/km) with performance tuning in the release-1.1-k8sm-tuning branch.

For non-Marathon managed Kubernetes, we start Kubernetes (etcd and km 2 containers) with Ansible Docker module, on meson-master node.

###Benchmark: Baseline scalability test: The test executes sequentially the steps below - we wait for completion of each step before starting the next one.

  1. Start container on swarm with busybox image, default docker networking with docker bridge and icc = true, and the default httpd server

  2. Capture the time it takes for docker run to return - 'Container Launched'

  3. Use inspect on launched container to find out when it goes to 'Running' state - 'Container Running'

  4. Use inspect to get IP address and host for the container and measure time to TCP connectivity.
