Services

The architecture contains the following services:

• Rabbitmq: It is used to pass messages between the manager and the planner, provisioner and deployer
• MySQL: Used by Ansible Semaphore
• Ansible Semaphore: This is used by the deployer to run playbooks on provisioned VMs to mainly install k8s cluster
• Logspout: A helping service to display all the log messages of all running services
• MongoDB: Used by the manager to store TOSCA templates
• TOSCA Simple qUeRy sErvice (SURE): A RESTful service for verifying and querying TOSCA templates. The API definition and documentation can be found here https://app.swaggerhub.com/apis-docs/skoulouzis/tosca-sure/1.0.0
• Planner: This service takes a TOSCA template as input that may contain only an application definition and generates a valid plan i.e. a plan that has all dependencies resolved.
• Provisioner: This service contacts a cloud provider to set up the virtual infatuate (mainly VMs)
• Deployer: This service initially deploys installs and configures k8's cluster on the virtual infatuate and next install docker containers on that cluster
