- Supported operating systems are CentOS 7.x or RHEL 7.x.
- Docker needs to be installed on the host where the installer is being run.
- Install a docker swarm cluster (or) Use the Contiv installer to install the scheduler stack after installing docker on a node external to the cluster where the scheduler stack is being installed.
