I have an ELB instance installed on my AWS account (http://editoradbosco.us-east-2.elasticbeanstalk.com), and it is working normally. My domain is installed on Hostgator (https://centrodombosco.org), and on this, I have a CNAME that points to my AWS endpoint (http://editora.centrodombosco.org).
However, I need to use an HTTPS (SSL) protocol. How can I proceed? I have an SSL contracted on Hostgator for this subdomain, but Hostgator has informed me that I need to make adjustments to AWS so that it works, but I do not know how to proceed.
How can I make this work?
I tried to create an SSL by Certificate Manager on AWS, appointing the CNAMES on my DNS Panel on Hostgator. But it fails. I guess its not possible to use AWS Certificates outside AWS Domains.
There are two ways you can do this.
Since you already have an SSL from Host Gator, you can import that certificate to AWS Certificate Manager (instructions here). Once you import a certificate it is immediately considered validated and you can immediately proceed to configure your EB environments Load Balancer to terminate HTTPS as described here.
Alternatively, if you’d like to use Amazon Certificate Manager but for some reason the DNS validation isn’t working, or its not possible for you to validate ownership of the domain using the DNS method, Amazon Certificate Manager also offers you the option to use email to validate your ownership of the domain, as described here. Once your ownership of the domain is validated you can then proceed to configure your EB environments Load Balancer to terminate HTTPS as described here.
As a side note, you may wish to consider using Route53 to handle DNS for your domain. Route53 is tightly integrated with AWS services such as ACM and, as is the case with ACM, services requiring custom DNS entries will often offer to make the correct DNS entries directly in to your Route53 hosted zone on your behalf.

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.
even if my dns records not pointing to aws route53,
someone has tried this before?
What records do I need to add in addition to A?
Unfortunately you cannot use the public ACM certificates directly on your instance as Amazon will only allow this to be deployed to Amazon managed resource such as:
Elastic Load Balancer
API Gateway
CloudFront
Without one of these services sitting in front of your EC2 you would need to rely on another solution. One of the following would be applicable:
Free service such as certbot allows you to generate a valid SSL that will need to be regenerated every 90 days.
Buy an SSL and deploy to the hosts.
Use the paid version of Amazon ACM Private CA (This can become quite expensive).
Route 53 is a DNS configuration service so its responsibility it to control DNS resolution i.e. example.com resolves to 1.2.3.4. HTTPS is a Layer 6/7 operation after DNS has been resolved and you're trying to connect to the application.
You need simply create the DNS records for your application (be that an A, Alias or CNAME record). In addition when verifying SSLs the provider would likely ask you to either perform email validation or DNS validation (create a record they provide) to successfully prove ownership.
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.
I am not into SSL at all, so bear with me please. I have no idea how to start to actually solve my problem.
Current situation:
1x Webserver with Webspace for a Website and it includes a Domain Administration, also to order SSL Certificates etc.
1x Different Webserver at Amazon Web Services with a PHP-based Software on it with Login etc.
A Subdomain that I created in the Domain Administration is pointing via DNS to the IP of the AWS.
What I need:
I want an https Connection (SSL) for the Subdomain that is pointing to the AWS so that the connection/login is secure.
My question is what I have to do on the side where I have the Domain Administration and after that what I have to do on the side of the AWS.
Thank you so much!
You have several options in hand,
If you already have a SSL certificate purchased, you can include it inside the webserver (e.g; configure apache for SSL).
If you plan to use free SSL certificates from Amazon, you can use one of the following options after creating a SSL certificate in AWS Certificate Manager.
Create a AWS CloudFront Distribution and attach the SSL certificate there while configuring an origin to forward traffic to the specific web server. However, you need to create the SSL certificate in North Virginia region and there won't be any upfront costs for CloudFront). CloudFront acts as a proxy and you can explicitly instruct to cache the static content reducing the load for web server and improving the performance.
The other option is to create a Application Load Balancer (ALB) and attach the SSL certificate there ( Create the SSL certificate in the same region) while forwarding traffic to the web server. However, this will add a monthly reoccurring costs for the ALB.
All you need to do is, on AWS ACM (AWS Certificate Manager) procure a certificate for your subdomain and use AWS ELB to use the certificate and point to the AWS webserver.
After this use the ELB IP in the DNS settings.
There are other options too like procuring the subdomain certificate and installing it on the webserver on AWS.
I'm in the process of moving from another cloud provider. Currently I'm just testing in the default environment that has a url looking like this:
http://example-env-1.us-east-1.elasticbeanstalk.com
I'm trying to get SSL/HTTPS working for this address. I then plan using a CNAME to redirect to this address and eventually move the nameservers over completely.
However, after setting everything else up successfully I get to the point of adding the certificates and it just says "failed":
And even though I have my actual "example.com" ssl certificate successfully issued nothing shows up in the load balancer certificate selection dropdown (and yes I have refreshed):
How do I enable SSL using the Certificate Manager?
That's because you are trying to request a cert for the elasticbeanstalk.com domain. You will not be able to get a cert for that domain as you are not the owner of it :). Nor can you setup https for the default elastic beanstalk domains they give you.
You should use ACM to get a certificate for your custom domain, the one you plan on making a CNAME record for.
Example:
If you were to own say the domain amyneville.com. You could create a cert through ACM for that domain.
If you use your custom domain, you do NOT need a to get a cert for the elasticbeanstalk.com domain.
A couple more things:
You cannot create a CNAME record on a TLD (amyneville.com). You can create the CNAME record for www.amyneville.com. So if you want to use the CNAME approach you will have to create a non-www redirect to www..
But better then a CNAME would be to use an A record and point it to the elastic beanstalk resource that was setup. So the load balancer that was created for you, use it's A record.
Last but not least, you cannot apply the ACM cert through the elastic beanstalk console. Instead you will have to use the AWS CLI tools. Here's a link on how to do it: https://stackoverflow.com/a/35173500/1445460
I was looking for this myself and found this useful blog post from one of the Amazon team ...
https://medium.com/#arcdigital/enabling-ssl-via-aws-certificate-manager-on-elastic-beanstalk-b953571ef4f8#.frcj0rj4t
Whilst you can't use the console to select the certificate as stated in your question you can use the Elastic Beanstalk CLI to set the certificate to one you have created in Certificate Manager.
