Managing container services (Docker)

IBM® Cloud Manager with OpenStack container support is based on Docker containers.

Before you begin

Before you begin, ensure you completed the following prerequisites.
  • The IBM Cloud Manager with OpenStack controller and compute nodes must be configured to use Docker containers. For more information, see Customizing for container services (Docker).
  • The availability zone for Docker compute hosts must be defined. However, if the cloud is deployed with the Platform Resource Scheduler (PRS), then it is not needed.
Note: The same security groups are supported by container instances as IBM Cloud Manager with OpenStack supports for OVS based networking.

About this task

The Docker driver is a hypervisor driver for OpenStack Nova compute. Using container services, you can automate the deployment of applications (as containers) and can manage multiple containers on a single compute node. Containers are not the same as virtual machines. A container operates at a process level, that makes them lightweight and fast for software delivery. Whereas, virtual machines are often used for hardware resource allocation.
