### Examples

Read the parameter value from a secret with id "my-secret-password": 

```yaml
parameters:
  Password:
    resolver: secret
    secretId: my-secret-password
```

Read the parameter value from a secret in a different region:

```yaml
parameters:
  MyParam:
    resolver: secret
    secretId: my-secret-password
    region: eu-west-1
```

Read the parameter value from a different account

```yaml
parameters:
  MyParam:
    resolver: secret
    secretId: arn:aws:secretsmanager:us-west-2:123456789012:secret:MySecret
    commandRole: arn:aws:iam::123456789012:role/SecretReader
```
