Use UploadServerCertificate with an AWS SDK or CLI

To upload a server certificate to your AWS account

The following upload-server-certificate command uploads a server certificate to your AWS account. In this example, the certificate is in the file public_key_cert_file.pem, the associated private key is in the file my_private_key.pem, and the the certificate chain provided by the certificate authority (CA) is in the my_certificate_chain_file.pem file. When the file has finished uploading, it is available under the name myServerCertificate. Parameters that begin with file:// tells the command to read the contents of the file and use that as the parameter value instead of the file name itself.

aws iam upload-server-certificate \
    --server-certificate-name myServerCertificate \
    --certificate-body file://public_key_cert_file.pem \
    --private-key file://my_private_key.pem \
    --certificate-chain file://my_certificate_chain_file.pem

Output:

{
    "ServerCertificateMetadata": {
        "Path": "/",
        "ServerCertificateName": "myServerCertificate",
        "ServerCertificateId": "ASCAEXAMPLE123EXAMPLE",
        "Arn": "arn:aws:iam::1234567989012:server-certificate/myServerCertificate",
        "UploadDate": "2019-04-22T21:13:44+00:00",
        "Expiration": "2019-10-15T22:23:16+00:00"
    }
}

Example 1: This example uploads a new server certificate to the IAM account. The files containing the certificate body, the private key, and (optionally) the certificate chain must all be PEM encoded. Note that the parameters require the actual content of the files rather than the file names. You must use the -Raw switch parameter to successfully process the file contents.

Publish-IAMServerCertificate -ServerCertificateName MyTestCert -CertificateBody (Get-Content -Raw server.crt) -PrivateKey (Get-Content -Raw server.key)

Output:
