      Goal

      As an OpenShift on vSphere administrator, I want to specify static IP assignments to my VMs.

      As an OpenShift on vSphere administrator, I want to completely avoid using a DHCP server for the VMs of my OpenShift cluster.

      Why is this important?

      Customers want the convenience of IPI deployments for vSphere without having to use DHCP. As in bare metal, where METAL-1 added this capability, some of the reasons are the security implications of DHCP (customers report that for example depending on configuration they allow any device to get in the network). At the same time IPI deployments only require to our OpenShift installation software, while with UPI they would need automation software that in secure environments they would have to certify along with OpenShift.

      Acceptance Criteria

      • I can specify static IPs for node VMs at install time with IPI
