My previous post lightly talked about about adding SSL certificates via the AWS Console. This post talks about adding your own SSL certificate to Certificate Manager via the AWS CLI. The CLI which makes it super simple to manage. It also allows for automation as well.
aws acm import-certificate \ --certificate file://Certificate.pem \ --certificate-chain file://CertificateChain.pem \ --private-key file://PrivateKey.pem
If successful, it will return ARN or Amazon Resource Name.
