}
catch (Exception e)
{
_logger.LogError($"An error occurred while getting a list of all the clusters in your AWS account. {e.InnerException}");
throw new Exception($"An error occurred while getting a list of all the clusters in your AWS account. {e.InnerException}");

#### [ CLI ]
**AWS CLI**
**列出可用的叢集**
下列 `list-clusters` 範例列出所有可用的叢集。
```
aws ecs list-clusters
```
輸出：
```
{
"clusterArns": [
"arn:aws:ecs:us-west-2:123456789012:cluster/MyECSCluster1",
"arn:aws:ecs:us-west-2:123456789012:cluster/AnotherECSCluster"
]
}
```
