To configure a compute node to use Docker, there is a Docker driver that needs to be installed on the compute node to use as the compute Nova compute's driver. There are directions for how to do everything, which we will discuss in the documentation in the GitHub repository for the nova-docker driver at https://github.com/openstack/nova-docker.
The first task is to delete the virtual machines running. Once the following configuration is completed, OpenStack will not be able to manage the virtual machines running on the compute node. Go ahead and delete any running instances you have.
Next, let's walk through the setup instructions. Start by logging into a compute node, installing git, docker, and Docker Python support, cloning the nova-docker GitHub repository, and running setup.py to install the driver:
compute# yum install -y git docker python-docker-py compute# systemctl enable docker compute# git clone https://github.com/openstack/nova-docker compute# cd nova...
