Key-Value Store

Portworx uses a key-value store for clustering metadata. This integration example utilizes the default etcd.

Storage

Ensure that at least one of the Portworx nodes has extra storage available. Use an unformatted partition or a disk-drive.

Storage devices explicitly given to Portworx are automatically formatted by Portworx. Before integrating Nirmata with Portworx, add an unused disk on each worker node of the same size and confirm that the mount point is /dev/sd*).

Shared Mounts

If running Docker v1.12, Docker must be configured to allow shared mounts propagation. If not, Portworx will fail to start.

Firewall

Ensure that ports 9001-9015 are open between the nodes that will run Portworx.

NTP

Ensure that all nodes running Portworx are time-synchronized and that an NTP service is configured and running.
