Esempio 1: per descrivere tutte le regioni abilitate
Nell'esempio di
describe-regions
seguente vengono descritte tutte le regioni abilitate per l'account.aws ec2 describe-regions
Output:
{ "Regions": [ { "Endpoint": "ec2.eu-north-1.amazonaws.com", "RegionName": "eu-north-1", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.ap-south-1.amazonaws.com", "RegionName": "ap-south-1", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.eu-west-3.amazonaws.com", "RegionName": "eu-west-3", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.eu-west-2.amazonaws.com", "RegionName": "eu-west-2", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.eu-west-1.amazonaws.com", "RegionName": "eu-west-1", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.ap-northeast-3.amazonaws.com", "RegionName": "ap-northeast-3", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.ap-northeast-2.amazonaws.com", "RegionName": "ap-northeast-2", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.ap-northeast-1.amazonaws.com", "RegionName": "ap-northeast-1", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.sa-east-1.amazonaws.com", "RegionName": "sa-east-1", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.ca-central-1.amazonaws.com", "RegionName": "ca-central-1", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.ap-southeast-1.amazonaws.com", "RegionName": "ap-southeast-1", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.ap-southeast-2.amazonaws.com", "RegionName": "ap-southeast-2", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.eu-central-1.amazonaws.com", "RegionName": "eu-central-1", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.us-east-1.amazonaws.com", "RegionName": "us-east-1", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.us-east-2.amazonaws.com", "RegionName": "us-east-2", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.us-west-1.amazonaws.com", "RegionName": "us-west-1", "OptInStatus": "opt-in-not-required" }, { "Endpoint": "ec2.us-west-2.amazonaws.com", "RegionName": "us-west-2", "OptInStatus": "opt-in-not-required" } ] }

Per ulteriori informazioni, consulta Regioni e zone nella Amazon EC2 User Guide.
Esempio 4: per elencare solo i nomi delle regioni
Nell'esempio di
describe-regions
seguente viene utilizzato il parametro--query
per filtrare l'output e restituire solo i nomi delle regioni come testo.aws ec2 describe-regions \ --all-regions \ --query
"Regions[].{Name:RegionName}"
\ --outputtext
Output:
eu-north-1 ap-south-1 eu-west-3 eu-west-2 eu-west-1 ap-northeast-3 ap-northeast-2 me-south-1 ap-northeast-1 sa-east-1 ca-central-1 ap-east-1 ap-southeast-1 ap-southeast-2 eu-central-1 us-east-1 us-east-2 us-west-1 us-west-2
