Allow parallelism

System Information

I'm using a terraform-module:

• it creates a vsphere-VM

This VM uses dynamic/DHCP for it's management-IP.

So your module seems to be perfect to pre-populate my OPNSense-Lab-Firewall with DHCP and DNS entries.

If I use the module twice, for two VM-instances, it breaks...

for example

c:\ terraform apply
...
╷
│ Error: mapping doesn't exists for this MAC address
│
│   with module.vcenter-v.opnsense_dhcp_static_map.vcsa-dhcp,
│   on ..\#modules\vsphere-vcenter\42-vcenter-static-dhcp-ip.tf line 8, in resource "opnsense_dhcp_static_map" "vcsa-dhcp":

╵
╷

╵
╷

│

Sometimes, DHCP and/or DNS-Entries get created, so after a dozen "terraform apply"-rounds all entries are there.

Since both modules get created in parallel:

• the terraform-provider-opnsense has two TCP/HTTPs-Sessions open towards the Firewall
  I suspect some parts in the code blocking each other.

Sometimes, it seems to end in an infinite loop:
