Mesos + Calico Demo

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.

Vagrant setup

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.

vagrant up

Linux setup

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/metaswitch-modules.git

Pre-load Docker images required for the demo

cd metaswitch-modules/
docker-compose pull

Build the demo (Vagrant and Linux)

From the metaswitch-modules directory

make images

Run the "before" demo

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-stars-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.sh

Run the Calico w/o isolation demo

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

Note: If using the Vagrant environment, these commands should be run from inside the virtual machine. Run vagrant ssh to log in.

Launch the demo cluster using docker-compose. This will bring up a single Mesos master and two slaves.

./demo/launch-cluster.sh

Wait until the cluster is up. Then

./demo/launch-stars.sh

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

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

Bring up the test probes and targets with isolation.

./demo/launch-stars-isolated.sh

Verify by visiting the visualization page.

• Vagrant (from the host OS): http://localhost:9002
• Linux: http://192.168.255.252:9001

Tear down the workloads.

./demo/stop-stars.sh
./demo/stop-stars-isolated.sh
