I have a CloudFront distribution already configured for an S3 bucket using Route53 domain with HTTPS enabled using a public certificate.
I want to use this CloudFront distribution with another origin (which is an EC2 instance running NGINX as a reverse proxy for an application on that same instance), but I also need to enable HTTPS.
The normal way I would enable HTTPS on EC2 with NGINX is to just setup the nginx configuration and point my domain "A record" to the instance then request a certificate with Let's Encrypt. But how should I do it when behind CloudFront? I won't use Let's Encrypt (not necessarily important to just use it) and would like to use an AWS public certificate as I did with my S3.
Could I just configure NGINX to listen on port 80 and add this EC2 instance as an origin on the CloudFront distribution then enable HTTPS and choose my public certificate there or how should this be done to work properly?
This time I am not going to use a Load Balancer, I want a direct connection between the EC2 and CloudFront. But I would also like to know how to set this up when using a Load Balancer (for the future).

Yes you can do this, but all traffic pattern will be:
Clinet---(HTTPS)--->CF---(HTTP)--->Instance
Which means that half of your connection (CF->Instance) will be in HTTP, which may not be desired.
If you want to have HTTPs on every path, you still need to have public valid SSL cerfiicate on the instance. CF will not work with self-signed certificates.

I would like to make the following structure for my web application
Visitor ==>>> CloudFront-> ALB -> ASG (nginx servers)
I have only one HTTPS certificate for my domain name. I will upload it to ACM but where to attach?
To the Cloudfront? Or to the ALB? Maybe to the hosts? Or everywhere the same?
Can I use the same in all places?
I tried to add it only to the NGINX but it can be used only locally and others from acm
Firstly you can use SSL on all levels (cloudfront, ALB, and Nginx Servers).
For Cloudfront, you need to upload your cert to ACM on us-east-1 region.
On clodfrount configuration page select alternate domain and put your domain to be used, then it will ask cert you need to select it from selection options.
For ALB you need upload it to ACM on ALB region.
While you go to listeners, then you configure listener for 443 or another you can select SSL cert on there.
For Nginx, you can use configure your nginx.conf to use cert. It will ask cert and key, you will put them on somewhere at disk.
BTW, You can configure only on cloudfront for visitors and you don't need to use SSL for internal communication if your data is not too important (Credit card etc.)
I have following setup at AWS ECS:
Container with Caddy web-server at 80 port that serves static files and performs proxying of /api/* requests to backend
Container with backend at 8000 port
EC2 instance at ECS
ALB at subdomain http://some-subdomain-12345.us-east-2.elb.amazonaws.com/ (subdomain was provided automatically by AWS) with HTTP Listener
I want to setup SSL certificate and HTTPS Listener for ALB at this subdomain that was provided by AWS - how I can do it?
P.S. I have seen an option for ALB with HTTPS Listener when we are attaching custom domain i.e. example.com and AWS will provide SSL certificate for it. But this is a pet project environment and I don't worry about real domain.
You can put your ALB behind CloudFront, which unlike ALB gives you a TLS certificate by default. So you can address your application at e.g.:
https://d3n6jitgitr0i4.cloudfront.net
Apart from the TLS certificate, it will give you the ability to cache your static resources at CloudFront's edge locations, and improve latency on the TLS handshake roundtrips.

You can't do this. This is not your domain (AWS owns it) and you can't associate any SSL certificate with it. You have to have your own domain that you control. Once you obtain the domain, you can get free SSL certificate from AWS ACM.
This could be a solution without using subdomains but using path redirection

I am trying to point CloudFront for my ec2 machine.
under origin, I am giving the public DNS name of the ec2 :(e.g. ec2-52-64-xxx-xxx.ap-southeast-2.compute.amazonaws.com)"
But I am getting this error:
I have opened 443 port also open on my ec2.
How can I solve this error?
Based on the chat discussion.
The application on the instance works over HTTP and port 80. It does not server HTTPS traffic in itself. So if you want to use the current setup with CF, you need to allow port 80 (not 443) and in CF using HTTP for origin protocol (not HTTPS). The way this works is that HTTPS and SSL will be only between client and CF, not between CF and your instance:
client----(HTTPS:443)--->CF----(HTTP:80)---->EC2 instance
As you can see above, there is a security issue. All traffic between CF and your instance will be in pain text over the internet. To rectify this, you need to add HTTPS to your instance. There are two ways for that:
Add load balancer in-front of your instance, and deploy custom domain on it with SSL from ACM and HTTPS listener. So the traffic will be:
client----(HTTPS:443)--->CF----(HTTPS:443)---->ALB---(private HTTP:80)--->EC2 instance
Setup SSL on your instance directly. For this you can't use ACM (except when your instance is enclave). Instead, you have to use third-party SSL provider. Common choice is https://letsencrypt.org/. Then you setup your Apache with the SSL certificate to serve HTTPS traffic. Subsequently, you will have:
client----(HTTPS:443)--->CF----(HTTPS:443)---->EC2 instance
I have enabled HTTPS for my custom domain name (haydenclay.page), but I also need the Beanstalk url (app-name.elasticbeanstalk.com) to run through HTTPS as well.
HTTPS does not work currently, because the cert name matches my custom domain name, yielding: ERR_CERT_COMMON_NAME_INVALID
I need HTTPS because I make API requests, and going from HTTPS to HTTP throws a mixed content error. How can I enabled HTTPS on the beanstalk url?
I have already tried making an alias
Sadly you can't enable https directly for app-name.elasticbeanstalk.com domain. This is because this domain is controlled by AWS. You can only register SSL certificates for domains that you control.
If you want to server your content from EB over ssl, you have generally three options.
Front your instance with load balancer. This is the easiest* way as you can associated ACM SSL certificate with the balancer for your domain.
Front your EB instance with CloudFront (CF). You can setup alternative name for your cloudfront domain with your CF distro and your SSL cert. You can also use ACM for that. Also easy setup, but it should be noted that traffic between CF and your EB instance will be http only, unless you also setup your own SSL cert (not from ACM) on the instances (point 3).
Install your own SSL certificate (not from ACM) directly on the EB instance, using nginx. This requires manual setup and a valid public certificate. Popular choice is LetsEncrypt, to get the SSL cert from.
If you use CloudFlare, go to DNS -> Records
Type: CNAME
name: api
Content: "YOUR_URL.eu-west-1.elasticbeanstalk.com"
Proxy status: Proxied
And call your new url: api.your_domain.com
I have a blog(codeoverflow.in) hosted on aws-ec2 instance. I am using cloudfront and acm certificate to provide ssl for my blog. But when I access codeoverflow.in or www.codeoverflow.in, cloudfront redirect me to https version successfully but gives the following error:
The request could not be satisfied. CloudFront wasn't able to connect
to the origin. Generated by cloudfront (CloudFront) Request ID:
TE89T-COJiVFgBGUpBG_2gWd6Iim3c-svHsborUct49O9Owjb3nl6g==
I have type A and type AAAA alias records for both codeoverflow.in and www.codeoverflow.in in route 53, all pointing to cloudfront distribution.custom ssl certificate is also configured for both domains.as of now I have dissociated elastic ip from ec2, but I want to use it as well together with cloudfront and ec2. Please help me to configure all three together.
It looks like you're trying to connect to your origin via HTTPS, but it doesn't sound like you have SSL enabled on your instance.
The easiest thing to do is use a hostname for your origin - i.e. www-origin.codeoverflow.in. Create a load balancer that listens on both 80 & 443, deploy an appropriate cert to that (you may have to create a new one, or create a wildcard) and put your instance behind that listening on port 80. Finally, create an ALIAS record in Rour53 from www-origin to your load balancer.
