Docker Services

 

Docker is revolutionary in the way that it automates the deployment of applications inside software containers, by providing an additional layer of abstraction and automation of operating-system-level virtualization. It acts as a lightweight virtualization platform that helps to have the benefit of OS level virtualization without the overhead of running multiple, parallel OSes.  It lets you drop ready-to-run “containers” into ANY hardware environment that supports Docker instances.

 

Advantages of Docker:

  • Docker containers vs. VMs
  • Rapid deployment
  • App isolation for safe sandboxing
  • Simplified testing
  • Easy configuration

 

Flocker, an open-source container data volume-manager allows a Flocker data volume, called a dataset, to be used with any container in the cluster. Unlike Docker volumes which are tied to a single server, Flocker datasets are portable, and can be easily moved between nodes in a cluster.

 

Advantages of Flocker:

  • Move databases to bare metal, or a different virtual machine
  • Minimal downtime while upgrading server hardware
  • Speed up time-to-recovery by attaching a new database container to an existing data volume
  • Run containers on bare metal but with the manageability of VMs
  • Migrate databases from spinning disk to SSD
