Newer AWS accounts may have some, or all AWS regions set to 'vpc-only', which means that they do not provide the EC2-classic environment. Instead, these regions have a 'default VPC' configured, which serves to emulate the EC2-classic environment. As of Bright 6.1, the default settings for extending a cluster into the cloud work fine with vpc-only regions.
On Bright 6.0, one has to make sure the following are true when bursting to a vpc-only region:
- base address of the cloud network is 172.31.0.0/16 (instead of 10.0.0.0/8 which is the default in Bright 6.0)
- base address of the netmap network is 172.30.0.0/16 (instead of 172.31.0.0/16 which is the default in Bright 6.0). This step may involve having to change the IPs of the "map0" interface for any existing nodes.
