SUMMARY

When creating multiple VPCs in a project it gets created with a network domain like this: cs<project_account_id>. This means all VPCs in the same project gets the same network domain. Creating instances with duplicate names in a project with the same FQDN is currently possible. This can create issues when registering these instances to FreeIPA etc.

Similarly, duplicate hostnames within a VPC can be created if the instances are in different tiers.

It would be nice to have an option to restrict duplicate instance names in a project, network domain and VPC.

@rajujith I can think of two solutions

• automatic resolution by adding a counter or adding vpc-id
• making the field obligatory and/or throw an error on conflict and let the user add the name
  not sure what is preferable, but I think user friendliness may suffer in both approaches.

@DaanHoogland these should do, there is one more option. A global setting to restrict duplicate instance names per network domain.
