This repository showcases Apache Mesos using Project Calico as the networking solution.

To get started you will need either:

• a Linux computer running a modern distribution
• a Windows or Mac computer where you will run the demo in a Linux VM.

Download and install VirtualBox and Vagrant.

Clone this repository.

git clone https://github.com/mesosphere/metaswitch-modules.git

Start the Vagrant VM. This will automatically provision the VM. Sit back and relax, it takes a few minutes to pre-load the Docker images used for the demo.

cd metaswitch-modules
vagrant up

Note: the shell provision step contains steps that must be performed each time the VM is booted. Append the --provision-with shell flag when running vagrant up or vagrant reload when booting the VM subsequent times.

The commands below should all be run from inside the virtual machine. Logging in is easy:

vagrant ssh

Install Docker: https://docs.docker.com/installation/

Install Docker-compose: https://docs.docker.com/compose/install/

Load Kernel modules used by Project Calico:

sudo modprobe ip6_tables
sudo modprobe xt_set

Clone this repository.

git clone https://github.com/mesosphere/net-modules.git

From the net-modules directory

make images

This first demo shows what life is like with "vanilla" Mesos: port conflicts and no network isolation.

./demo/launch-cluster-before.sh

Wait until the cluster is up, then visit http://localhost:5050/

You should see a working Mesos status page with no tasks and two slaves.

Then

./demo/launch-probes-before.sh

Show the Mesos status page, and watch for the "collect" task to start. Then visit http://localhost:9003/ to see the visualization. You should see only two probes are running.

Tear down the cluster for your next demo.

./demo/stop-cluster-before.sh

This demo shows Calico without network isolation. All probes can reach one another.

./demo/launch-cluster.sh

Wait until the cluster is up. Then

./demo/launch-probes.sh

This brings up the test probes and targets with no isolation---everything can talk to everything else. Verify by visiting the visualization page.

• Linux: http://192.168.255.253:9001/
• Vagrant (from the host OS): http://localhost:9001/

Bring up the test probes and targets with isolation.

./demo/launch-probes-isolated.sh

Verify by visiting the visualization page.

• Linux: http://192.168.255.252:9002
• Vagrant (from the host OS): http://localhost:9002

Tear down the test workloads.

./demo/stop-probes.sh
./demo/stop-probes-isolated.sh

Or, alternatively simply tear down the cluster.

./demo/stop-cluster.sh
