I built a web app on top of aws elastic beanstalk cli. I'm trying to add a SSL certificate to the site to make it more secure. The documentation says "The simplest way to use HTTPS with an Elastic Beanstalk environment is to assign a server certificate to your environment's load balancer". However, I don't see my app on the Elastic Beanstalk console although is is up and available to the public. Does anyone know how to use HTTPS with an Elastic Beanstalk environment and/or to assign a server certificate to my environment's load balancer (not sure how to access my env load balancer either).
Did you choose the right region when you logged into the console? That would be the only reason you don't see the app. Once you choose the right region, you should see your application. You can add a cert by going to the Elastic Beanstalk console ==> configurations ==> Load balancer and Add Listener, choose 443, https and the cert. Just make sure to add port 443 and open traffic on that port in the load balancer's security group. This blog post explains the process in ABC simple, step-by-step manner:

I have an application running on an AWS EC2 instance, port 8501. I cannot change the port for multiple reasons. I set up a reverse proxy with nginx using this YT tutorial to redirect http://[domain].com to port 8501.
That works fine.
I obtained an SSL certificate from AWS Certificate Manager and have since learned that AWS certificates only work with certain AWS services, here, here, and here. However, none of those StackOverflow links--or the AWS instruction pages linked therein--actually described how to connect the https request to the Application Load Balancer to the EC2 instance as set forth by my nginx reverse proxy above.
That is, I've more or less followed this YT tutorial to set up a load balancer and attach the SSL certificate obtained from AWS Certificate Manager, but when I type https://[domain].com, I receive a "site can't be reached" error. http://[domain].com still works.
I've tried both HTTP:80 and HTTPS:443 for the Protocol:Port in my Target Group required by AWS Load Balancer. What more do I need to do?
EDIT: added images with ALB settings, etc:
load balancer listeners
target group overview
nginx config settings
I am trying to implement SSL certificate on my EC2 instance which is running a laravel project. I have issued the certificate and it is also in use but when I try https://domainName my browser shows
Unable to connect
I have used:
EC2
Route53
Certificate Manager
Load Balancer
Elastic Beanstalk
This is exactly how I configured my Load Balancer, Then added my DNS Name to Route53.
I didn't know what details should I provide so please do ask for the information.
Check the web service if it is working correctly locally in you ec2 and listen on port 8o, then apply ssl offloading with application load balancer: please check the following example: https://infra.engineer/aws/36-aws-ssl-offloading-with-an-application-load-balancer
I am really struggling to get my basic website (literally just a template without any changes, just running ASP.NET) to work with HTTPS. I am using an Elastic Beanstalk environment to host the site, and the site EC2 virtual machine is behind a load balancer (classic).
I have followed the guide here
And believe I have everything configured correctly, however when I browse to https://www.playground.cloudy-skies.org/ or even the http:// version, I get a HTTP ERROR 503.
I have created an SSL certificate using AWS certificate manager:
I have the load balancer in AWS configured like so:
As per the website documentation, my domain name is pointing to the elastic beanstalk instance, not the load balancer. I've checked the AWS official doco and it says to do pretty much this. Where am I going wrong? if I browse the site with Fiddler active I get:
Please help? I'm a software developer more than I am a network guy, so I'm doing my best here but I'm struggling and have yet to successfully create a site that uses HTTPS.
First thing if you are using Beanstalk your Route 53 will be pointing to your Beanstalk Url only. You can change even force it your Loadblancer also but it doesn't make any change.
As your HTTPS (Port 443) is not working, just check the Security Group of EC2 instance and ELB (Elastic Load Balancer). Sometimes it happens Security Group block your Port.
So in Your Inbound Rules, (for both ELB and EC2) 443 port should be included
What is my indication that I am using AWS Certificate Manager correctly and that any remaining problems getting my site to load at https are due to a mistake I am making in my Apache configuration?
In AWS Certificate Manager, I see "Success! Your certificate was issued successfully." Does that mean there are no further steps for me to complete in the AWS console, and I need only get my Apache configuration correct to finish?
Currently, when I try to visit a URL at my site with the http protocol, it loads fine, but when I visit at https, the browser tries to load the page but it never loads.
I have followed the instructions for creating an HTTPS listener, but still do not know if I am done with all necessary steps in AWS console. How would I know?
Edit: To clarify, I am using an Elastic Load Balancer (ELB), since the documentation indicated I need to use ELB with AWS Certificate Manager (ACM). However, I do not know how to determine if I have configured everything correctly in AWS console that I need to in order to access the site at HTTPS.
Edit 2: This might come close to answering my question, possibly, but I don't know how to do this: "You can use curl, telnet etc from your local machine to verify 443 port status on ELB" -- #vivekyad4v.
ACM(AWS Certificate Manager) supports the AWS resources like ELB, Cloudfront, API Gateway etc. You can add SSL certificates to these
resources via AWS console.
Currently, it doesn't support EC2. You cannot use ACM with EC2 instances, you will need a Load Balancer in front of it. Once you have a load balancer, SSL termination happens on the load balancer & not on the EC2 instance.
Once it is setup, you can change your apache server config to redirect all HTTP requests to HTTPS.
Add certificate to ELB - "https://docs.aws.amazon.com/elasticloadbalancing/latest/classic/elb-update-ssl-cert.html"
Update apache config - "https://aws.amazon.com/premiumsupport/knowledge-center/redirect-http-https-elb/"
No EC2 support - "https://aws.amazon.com/certificate-manager/faqs/"
I am setting up AWS Elastic Beanstalk application and I want the traffic to it to be HTTPS.
I created a DNS CNAME record matching the beanstalk url and created and approved a certificate for that DNS name in AWS Certificate Manager.
Now I went to Elastic Beanstalk environment --> Configuration --> Network Tier / Load Balancer (Image below) in order to set the "Secure listener port" from OFF to 443 and choose my certificate.
But my certificate is not there to choose from !
So My question is how to get my certificate or a certificate into that selection list, or is that a bug in AWS?
Note - I was able to see my certificate when going to EC2 / Load balancers and was able to change the load balancer from HTTP to HTTPS and choose my certificate there.
But this did not reflect on Elastic Beanstalk load balancer configuration that still shows port 80. Using HTTPS to the beanstalk did not work this way.
Help!
Through the console, there is currently no way to assign your certificate you created in the Certificate Manager to your Beanstalk environment.
In order to accomplish this, you will need to use the AWS CLI. I was able to accomplish this, and luckily, it is easy.
In short, you need to:
create a elb-acm.json file and place it somewhere in your web root. I put mind directly in the web root of my application.
go to the Certificate Manager and get the arn ID of your certificate
use the update environment command to apply your certificate to your environment
aws elasticbeanstalk update-environment --environment-name Your-Environment --option-settings file://PATH-TO-JSON/elb-acm.json
For me the path was simply file://elb-ecm.json since (I believe the reason is because) I was running the command while in the web root and the file was in that same directory This article goes into detail (and worked for me). Good luck!
Please note, though you can, you should NOT assign the certificate directly through the Load Balancer console (EC2 > Load Balancers) because the load balancer will be blown away and recreated whenever you rebuild your Beanstalk Environment.
Also, make sure you have setup your certificate how you want it before you apply it to your Beanstalk environment. For example, if you want *.mydomain.com and the naked mydomain.com to both be secure, make sure that's fully configured first since there is no easy way to "de-associate" your certificate from your environment once your run these commands (you would basically need to terminate your environment altogether and create a new one if I'm not mistaken in this scenario).
Also, you will want to have some redirect code in your app to perform a 301 redirect on any non-secure request coming in once you have your certificate setup. To perform the redirect you will need to look for the X-Forwarded-Proto header on the incoming request. If it's not secure, you should redirect to the secure port. For example, here is how my application code looks:
// in production, only allow secure requests (https)
public function performSecureRedirect(rc) {
// based on domain comparison
var isLive = myEnvironmentData.isLive;
// setting up the health check url is important for smooth beanstalk deployments
// beanstalk issues this healthcheck request via a non-secure port
var isAmazonHealthcheckUrl = rc.event eq "system.healthcheck";
if (isLive and not isAmazonHealthcheckUrl) {
var headerData = getHTTPRequestData().headers;
// x-forwarded-proto is a special header
// setup by Amazon ELB (Elastic Load Balancer)
var requestProtocol = getHttpRequestData().headers['x-forwarded-proto'];
var isSecureRequest = requestProtocol eq "https";
if (not isSecureRequest) {
location("https://" & cgi.server_name & cgi.path_info, false, 301);
}
}
}
The answer by Brian FitzGerald and this blog helped me figure out a simple way to do that (set https on the Elastic beanstalk load balancer and use a CRM certificate for it).
The solution is simpler using AWS Elastic Beanstalk CLI (eb for short). After you set up the environment properly you can use eb config command.
When the edit window opens up scroll down to aws:elb:loadbalancer section.
Modify the load balancer section to be so (in my case I removed port 80 altogether, you may want to keep it):
aws:elb:loadbalancer:
CrossZone: 'true'
LoadBalancerHTTPPort: 'OFF'
LoadBalancerHTTPSPort: '443'
LoadBalancerPortProtocol: HTTP
LoadBalancerSSLPortProtocol: HTTPS
SSLCertificateId: PLACE HERE THE CRM CERTIFICATE ARN
SecurityGroups: '{"Fn::GetAtt":["AWSEBLoadBalancerSecurityGroup","GroupId"]},{"Ref":"AWSEBLoadBalancerSecurityGroup"}'
The arn of the certificate can be found in AWS > Certificate Manager.
Open the certificate and copy the ARN number (on the bottom right).
I saved the configuration, waited for the environment to get updated and that was it.
