Mesos Demo

Cluster Provisioning

Infrastructure

• Demo Cluster
  • 1 Master Node
  • N <= 10 Worker Nodes
• Fault Tolerant Cluster
  • 2 Master Nodes
  • N <= 100 Worker Nodes
• High Availibility Cluster
  • 3 Master Nodes
  • N <= 1000 Worker Nodes

Current version does not have a distributed file system and thus makes data persistence an issue. However, that limitation is has many solutions available, below is an example using AWS.

Database:

• MySQL deployed and managed via RDS
• MongoDb deployed and managed via MMS(very similar to RDS, runs on AWS)
• DynamoDb alternate NoSQL database

File Storage:

• Create EC2 instances with EBS mounts that DO NOT terminate with instance.
• Use S3 for file storage, either streaming directly or doing periodic sync.

Note: With the limitation of persistence also comes a big advantage of being able to scale down to optimize for cost.

Mesos

Installation and configuration of mesos and related software packages is handled via ansible scripts.

cd ansible
cp hosts.sample hosts
// Modify hosts file to match your cluster config
cp ansible.cfg.sample ansible.cfg
// Update the keypath in ansible.cfg
ansible-playbook mesos-cluster.yml

App Containers

Example Drupal Application

cd example/drupal
// Create local environment
make local
// Connect to the local environment via shell
docker exec -it drupal bash
// To install a dev db into mysql
// First connect to local environment via shell
make install
