VMmanager 6 architecture


VMmanager 6 architecture is based on Docker allowing to create and manage containers. A Docker container is an isolated environment where an application is running and the required environment is configured.

A docker image is required for running a docker-container. It defines the processes that will run in a container, its parameters, and environment settings.  E.g. the image can contain an operating system with the pre-installed webserver and corresponding network settings.  It is not possible to change the docker image of a running container. 

VMmanager 6 consists of three docker containers:

  • vm_box — the main container which contains services for the control panel. For example, the user authentication service and the webserver; 
  • graphite — the container with VM and cluster nodes usage statistics;
  • mysql — the MySQL management container.
