Features

Core Components

• Consul for service discovery
• Vault for managing secrets
• Mesos cluster manager for efficient resource isolation and sharing across distributed services
• Marathon for cluster management of long running containerized services
• Kubernetes for managing, organizing, and scheduling containers
• Terraform deployment to multiple cloud providers
• Docker container runtime
• Traefik for proxying external traffic
• mesos-consul populating Consul service discovery with Mesos tasks
• Mantl API easily install supported Mesos frameworks on Mantl
• Mantl UI a beautiful administrative interface to Mantl

Addons

• ELK Stack for log collection and analysis
  • Logstash for log forwarding
• GlusterFS for container volume storage
• etcd distributed key-value store for Calico
• Calico a new kind of virtual network
• collectd for metrics collection
• Chronos a distributed task scheduler
• Kong for managing APIs

See the  addons/  directory for the most up-to-date information.

Goals

• Security
• High availability
• Rapid immutable deployment (with Terraform + Packer)

Architecture

The base platform contains control nodes that manage the cluster and any number of resource nodes. Containers automatically register themselves into DNS so that other services can locate them.

Control Nodes

The control nodes manage a single datacenter. Each control node runs Consul for service discovery, Mesos leaders for resource scheduling and Mesos frameworks like Marathon.

In general, it's best to provision an odd number (at least 3 or 5) of control nodes to achieve higher availability of services. The Consul Ansible role will automatically bootstrap and join multiple Consul nodes. The Mesos role will provision highly-availabile Mesos and ZooKeeper environments when more than one node is provisioned.

Resource Nodes

Resource nodes launch containers and other Mesos-based workloads.

Edge Nodes

Edge nodes are responsible for proxying external traffic into services running in the cluster.

Getting Started

All development is done on the  master  branch. Tested, stable versions are identified via git tags. To get started, you can clone or fork this repo:

normalgit clone https://github.com/CiscoCloud/mantl.git

normal

To use a stable version, use  git tag  to list the stable versions:

normalgit tag
0.1.0
0.2.0
...
1.0.2


git checkout 1.0.2
normal

A Vagrantfile is provided that provisions everything on a few VMs. To run, first ensure that your system has at least 2GB of RAM free, then just:

normalvagrant up
normal

Note:

• There is no support for Windows at this time, however support is planned.
• Use the latest version of Vagrant for best results. Version 1.8 is required.
• There is no support for the VMware Fusion Vagrant provider; hence your provider is set to Virtualbox in your Vagrantfile.

Software Requirements

The only requirements for running Mantl are working installations of Terraform and Ansible (or Vagrant, if you're deploying to VMs). See the "Development" sections for requirements for developing Mantl.

Deploying on multiple servers

Please refer to the Getting Started Guide, which covers cloud deployments.

Documentation

All documentation is located at http://docs.mantl.io.

To build the documentation locally, run:

normalsudo pip install -r requirements.txt
cd docs
make html
normal

Roadmap

Mesos Frameworks

• Marathon
• Kafka
• Riak
• Cassandra
• Elasticsearch
• HDFS
• Spark
• Storm
• Chronos
• MemSQL

Note: The most up-to-date list of Mesos frameworks that are known to work with Mantl is always in the mantl-universe repo.

Security

• Manage Linux user accounts
• Authentication and authorization for Consul
• Authentication and authorization for Mesos
• Authentication and authorization for Marathon
• Application load balancer (based on Traefik)
• Application dynamic firewalls (using consul template)

Operations

• Logging (with the ELK stack)
• Metrics (with the collectd addon)
• In-service upgrade with rollback
• Autoscaling of worker nodes
• Self maintaining system (log rotation, etc)
• Self healing system (automatic failed instance replacement, etc)

Supported Platforms

• Amazon Web Services
• CenturyLinkCloud
• Cisco Cloud Services
• Cisco MetaCloud
• DigitalOcean
• Joyent Triton
• Google Compute Engine
• OpenStack
• Vagrant (Linux/OSX + VirtualBox)
• Apache CloudStack
• Cisco Unified Computing System
• Microsoft Azure
• Vagrant (Windows + VirtualBox)

Community Supported Platforms

• Bare Metal
• IBM Softlayer
• VMware vSphere

Please see milestones for more details on the roadmap.

Development

If you're interested in contributing to the project, install Terraform and the Python modules listed in  requirements.txt  and follow the Getting Started instructions. To build the docs, enter the  docs  directory and run  make html . The docs will be output to  _build/html .

Good issues to start with are marked with the low hanging fruit tag.

Getting Support

If you encounter any issues, please open a Github Issue against the project. We review issues daily.

We also have a gitter chat room. Drop by and ask any questions you might have. We'd be happy to walk you through your first deployment.

Cisco Intercloud Services provides support for OpenStack based deployments of Mantl.
