I deployed a DRF application on Elastic Beanstalk and now I need to make it https.
I requested a public certificate from AWS ACM using EB URL for domain name but got the following message.
You cannot request a certificate for Amazon-owned domain names such as those ending in amazonaws.com, cloudfront.net, or elasticbeanstalk.com.
Now the question is can I get a certificate without spending money on domain?
I tried to get a free subdomains but none of them had the functionality to manage DNS settings.
can I get a certificate without spending money on domain?
No. For valid SSL certificate you need your own domain, or domain that you control. There are free domain providers, but for anything other than testing, you need to pay for a domain.

Apologies on the broad title;my question is mainly around validating domain names in AWS Certificate Manager such that I can get valid ACM going. These are currently in Heroku and need to be migrated into AWS.
The Heroku ACM will validate a custom domain and issue a certificate if the DNS for said custom domain is a CNAME to the Heroku app's main domain. For example, if I have my-heroku-app.com and I make a CNAME from example.com to that then Heroku will successfully generate a cert and I can visit https://example.com with proper TLS. This can be verified with a simple curl -Iv https://example.com which shows a certificate issued by Let's Encrypt.
Conversely the AWS Certificate Manager requires a specific CNAME record and value to be set on a domain in order for it to generate certificates for that domain. Until that happens, I do not see a way to use things like API Gateway or ELB with said domain.
Is there a way I can migrate these domain certificates into AWS Certificate Manager from Heroku, e.g. without having to go through the typical validation process for each one of them? The main Heroku app domain is one which is going to be pointed to AWS via API Gateway and at that point all of those custom domains will fail because they're not registered in AWS API + Certificate Manager.

There is absolutely nothing stopping you from creating the ACM validation CNAME records in your DNS service, to complete the creation of the certificate in ACM, while still leaving all your current DNS records in place. The ACM validation record is just a new DNS record, it doesn't replace any of your existing records, and it is only used for validation that you own the domain name, it isn't used for actual routing of any network requests.

You have to go through the validation for each one, there is no getting around that. You could script it if you have a lot of them.

This is incorrect. You don't have to "register a domain to AWS Certificate Manager" in order to validate the certificate and get the certificate. ACM isn't validating that you have a domain pointing to an AWS API before it issues you the certificate. It is just validating that you own the domain name, via a new CNAME record that is only used for domain ownership validation.
I suggest you start the certificate creation process in ACM, and look at the CNAME record it asks you to create. You will see that it is totally unrelated to any of your current DNS records, and does not conflict with them.
I have created a subdomain demo.mysite.com which is hosted over godaddy.com. I have successfully mapped the subdomain demo.mysite.com to my AWS elastic IP in the go daddy console
On my AWS EC2 instance my website is secured runing over HTTPS and I have deployed the certificates corresponding to demo.mysite.com on my AWS EC2 instance. Now the problem I am facing is
1 - When I access my subdomain it points to my EC2 instance and the URL in my web browser changes to my Elastic IP ie www.demo.mysite.com --->> https://201.12.34.58:8443/myApp , which must not happen and it must remain as https://demo.mysite.com
2 - And since my URL changes so I start getting the certificate error saying
The certificate is only valid for demo.mysite.com.
Error code: SSL_ERROR_BAD_CERT_DOMAIN
Can someone help in solving these two issues, I feel that if first issues gets solved the second issue will automatically get solved. I am not sure though
Guys I need your help
I suggest to manage your domain DNS with CloudFlare. Add a CNAME record for your subdomain demo which points to that IP. On CloudFlare Console go to Crypto > Origin Certificates. Create a new one with RSA, then import it to AWS Certificate Manager at us-east-1. For the certificate chain use this. Be sure that Always use HTTPS in Crypto tab is on. After some minutes you should be using your domain pointing to AWS with HTTPS working fine.
That's what I did to make a subdomain to work with an AWS API endpoint with SSL.
I created an SSL certificate last night for use with an API (Tomcat, Spring Boot) on AWS Elastic Beanstalk using instructions provided by Amazon Certificate Manager.
When creating the cert, I entered the URL of my static site that calls the API, which is hosted by GoDaddy. ACM sent an email to my URL which I opened and approve and I now see the cert as issued, by Amazon, in my certs. I am also able to select it when I configure HTTPS for my EB load balancer. I am not able to export this cert though as it isn't private.
My question is, how is domain name used? I think I'm a little confused about how to use SSL on both my API and my static site AS WELL as the small bit of static content I'll host out of Tomcat.
Thanks.
ACM certs can only be used with AWS services - Cloudfront (if the cert is issued in us-east-1) and regionally on the classic load balancer and application load balancer.
You cannot export the cert for use in other products, so if you wanted to have Tomcat handle SSL you would need to get either a commercial cert or use something like Let's Encrypt.
If you have multiple host names you want to protect, you have different options.
You can get one cert per hostname if they are running on completely separate infrastructure; you can also have multiple host names in a single cert - even if there are multiple domains; and finally you can get a wildcard cert.
We built web APIs using Spring Boot. It is currently deployed on AWS Elastic Beanstalk. HTTPS is enabled with a self-signed certificate for development and testing. We plan to go live soon, so probably need to get a public certificate from a Certificate Authority.
Amazon has a certificate manager which is the easiest way to get a certificate for application deployed on Elastic Beanstalk. However, it requires some DNS set up on the server side which means you have to own the domain. I also looked at a popular free CA, Letsencrypt. But it also requires domain validation. We don't own a domain yet. The APIs are still using the long url from Beanstalk environment, something like my-app.us-east-2.elasticbeanstalk.com. I wonder if there is any website to download domain independent certificate which can be used for Beanstalk web applications without a domain?
If somebody could get a certificate for a domain he does not own he would be able to impersonate that domain, for example within a man in the middle attack. This would essentially break the security of HTTPS since encryption will not help to protect your data if you don't do the encryption with the real server but instead with a server owned by the attacker.
That's why there is no such thing as domain independent certificate. And that's why you should not be able to get a certificate for a domain you don't control.
I brought a domain (not in AWS) and parked it on AWS. I also got a certificate in AWS Certificate manager, for a domain I use for a shopify store.
On the shopify admin, I see that SSL isn't available for the purchased domain.
Is there a way to connect the domain with the certificate if the server is actually on shopify ?
ACM certificates are only for use with CloudFront and Elastic Load Balancers. You could possibly setup a CloudFront distribution in front of your Shopify domain in order to use the certificate that way, but it's probably more trouble and expense than it is worth.
You might look at moving your DNS hosting to CloudFlare and using their free SSL service.
The SSL certificate generated from ACM are only for use into AWS service who you cannot move move that certificate to a Shophify server. Please refer this.
