How does Mantl compare to OpenStack Magnum?
Mantl and Magnum are currently not integrated. However, the projects could compliment one other. Magnum provides an OpenStack API to instantiate a containerized environment within an OpenStack cloud. Magnum supports a range of container clustering implementations and Operating System distributions. Please refer to the Magnum wiki for additional Magnum details.
Mantl is an end-to-end solution for deploying and managing a microservices infrastructure. Mantl hosts are provisioned to OpenStack and other supported environments using Terraform. Terraform configuration files manage OpenStack services such as compute, block storage, networking, etc. required to instantiate a Mantl host to an OpenStack cloud. The Terraform OpenStack Provider would need to be updated since it does not support Magnum. If/when this is accomplished, adding Magnum support to Mantl should be simple.
How does Mantl compare to Kubernetes?
Kubernetes is an open source orchestration system for Docker containers. It handles scheduling onto nodes in a compute cluster and actively manages workloads to ensure that their state matches the users declared intentions. Using the concepts of "labels" and "pods", it groups the containers which make up an application into logical units for easy management and discovery.
Mantl is an end-to-end solution for deploying and managing a microservices infrastructure. Mantl currently uses Apache Mesos as a cluster manager for microservices. The Mantl team is in the process of evaluating Kubernetes as a cluster manager. The Mantl roadmap will be used to provide details if/when Kubernetes is supported.
