FAQ

AWS AMI

Error: AMI Name: '[NAME-OF-YOUR-AMI]' is used by an existing AMI: '[ID-OF-YOUR-AMI]'

It means your AMI with name '[NAME-OF-YOUR-AMI]' already exists in your AMIs (some time you have your region to find the exists AMIs). In this case you should:

• Remove exists AMIs: remove exists AMI with name '[NAME-OF-YOUR-AMI]', ref to deregister-ami if you want to see more detail.
• Rename your ami_name attribute in your *.pkr.hcl: rename the attribute in your *.pkr.hcl file to not exists name.
