Troubleshoot AWS VPC errors
When deploying a Bitnami Multi-Tier Solution on AWS, you may encounter an error similar to the one below:
Value (us-east-1b) for parameter availabilityZone is invalid. Subnets can currently only be created in the following availability zones: us-east-1d, us-east-1a, us-east-1c, us-east-1e.
This error typically occurs for one of two reasons:
Older AWS accounts created before 2013-12-04 do not have a default VPC configured and therefore cannot use certain availability zones. In these cases, we recommend that you create a default VPC via AWS technical support. Alternatively, you can also create a new AWS account, which will come with a default VPC already configured.
For newer AWS accounts that have a default VPC configured, the selected availability zones may be the same or there may not be a default VPC for the selected availability zones. In these cases, modify your deployment configuration and select different availability zones.
