AWS SDK Load Config

Occasionally I was getting this random error when running Terraform.

╷
│ Error: error configuring Terraform AWS Provider: no valid credential sources for Terraform AWS Provider found.
│ 
│ Please see https://registry.terraform.io/providers/hashicorp/aws
│ for more information about providing credentials.
│ 
│ Error: RequestError: send request failed

│ 
│   with provider["registry.terraform.io/hashicorp/aws"],
│   on main.tf line 10, in provider "aws":

Here’s the fix. Place this in your ~/.bash_profile.

export AWS_SDK_LOAD_CONFIG=1

This forces Terraform to use both config and credentials file.

AWS ACM List Certificates

How to list SSL certificates in AWS Certificate Manager.

aws acm list-certificates

Result

{
    "CertificateSummaryList": [
        {
            "CertificateArn": "arn:aws:acm:us-east-1:xxxxxxxxxxxx:certificate/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx",
            "DomainName": "mydomain.com"
        }
    ]
}

Describe details about the certificate.

aws acm describe-certificate \
--certificate-arn arn:aws:acm:us-east-1:xxxxxxxxxxxx:certificate/xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx \
--region us-east-1 \
--profile my-profile

AWS Search for RDS

Here’s a simple way to search for a RDS instance in AWS via CLI.

You may have to cycle through accounts and regions to find it.
