Cloud Specific Requirements

The Deployment Manager does not require a dedicated host, but its host must be separate from any clusters or nodes it manages.

Cluster Node Requirements

The cluster nodes are created by the Deployment Manager based on a user-defined launch script. The cluster node requirements include:

  • CentOS 7/RHEL 7 - Okera installs Java if not present.
  • For AWS related node requirements see the AWS Guide.

Network Requirements

There must be full network connectivity between the nodes in the cluster and the Deployment Manager.

Okera CLI Requirements

Any machine running the Okera CLI (that is, command-line tools), ocadm must have network access to the Deployment Manager and cluster machines. The CLI can be installed on the Deployment Manager host or any workstation or development environment with network access to the Deployment Manager and the cluster.

The CLI requirements include:

  • OS
    • RHEL 6 or later
    • Ubuntu 14.04 or later
    • OS X Darwin 10.11 (OS X El Capitan) or later
