I have two docker containers in beanstalk instances, One listen on port 80, another one listen port 8080. The security group allows port 80,8080. I can access url on port 80 and 8080 using http. I want to use https. I have created a certificate in ACM. Updated the load balancer in beanstalk env as below. but now i can not access website using https.ImagePorts
You need to https listener in your Load balancer, from the image the protocol is https but the port is 80
Create an https listener in LB
Map 443 of LB with 80 of the target
allow 443 in the SG of LB
instance port should be 80. As the SSL traffic decrypt before sending to the target.
If you are interested to add SSL with 8080 then you need to specify certificate with 8080 as well.

I remember doing it before but now it seems I have forgotten the process.
I want to create an HTTPS listener for an ALB. However, I don't have anything in my ec2 running on 443.
Should I configure a reverse proxy which points 443 to the app running port or add my HTTPS listener with port 80 HTTP target group?
Could someone help me with this?
You need a single Target Group pointing to your EC2 instance on port 80.
Then you can create a port 443 listener on the ALB that uses that target group. You will have to attach an SSL certificate to the listener when you create it. The ALB will terminate the SSL connection and send the request to the backend server over port 80.
I have an EC2 webserver which is serving up an app that listens on ports 80,8080, 443 and 8443. Outside clients need to talk to it on those ports (no port translations). I'm trying to put this behind a load balancer but the plethora of required ports is confusing me.
I have one ALB listening on the 4 ports, all forwarding to the same Target Group. The Target group has a default port of 443 but has the web server registered as 4 different targets, one for each of the ports (80,8080,443,8443).
Is this the correct way to go about this? Traffic doesn't seem to be flowing correctly. I'm concerned the ALB is receiving traffic on 443 and fowarding it to the server a different port, picking ports from the Registered targets. Do I need 4 different target groups, each with only 1 registered target?
You will need to setup your listeners to connect to the backend using the same port numbers (80->80, 443->443, ...) if you do not want any port translations.
So in your setup you will need your backend listening on ports 80, 443, 8080, 8443.
You will need ALB listeners setup to listen on 80, 443, 8080, 8443. Your listeners will forward requests to the same port that it is listening on (80 -> 80, 443 -> 443, ....)
Make sure that you set the type of listener correctly to match your protocols (HTTP or HTTTP). If your listeners are configured for 443 -> 443 and HTTPS -> HTTPS then you will need SSL certificates configured on the backend. Otherwise you can configure your listeners to SSL terminate and do HTTPS (443) to HTTP (443) but make sure that the backend is not configured for HTTPS in this case.
This may seem confusing at first - it is not. Just think of a Listener as the middle-man. He can either repeat your request (HTTPS -> HTTPS) or translate (HTTPS -> HTTP). Listeners can listen on one port (80) and forward to another port (8080). Each of these items is configurable.
I am using an https load-balancer, on the top of an instance group.
I want to set on one server that he will listen on port 443, a second one that will listen on port 444 and the third that will listen on port 445.
How should I add the TCP backend service to existing https load balancer google cloud?
You want to create a HTTPS loadbalancer listening on the 443 port and forwarding the traffic to serves listening on different pots. The encrypted connection will be terminated on the loadbalancer from there the traffic will be sent to the Backends.
When you add the backends to the loadbalancer you will have to select the port to which you redirect the traffic for each one of them.
Therefore having 3 ports would require having three backends serving on the port 443, 444, 445.
In order to add a backend you can run the following command or edit the loadbalancer from the console:
gcloud compute backend-services add-backend BACKEND_SERVICE_NAME [...]
I have ELB setup in AWS
1. TCP port 443 forward to 8080 port on instance (nginx)
2. www.example.com point to ELB dns
3. myserver.mydomain is my instance hostname
Now i have setup ssl on ELB for domain www.example.com
Now for ssl on nginx so that all communication is ssl. I want o know that
DO i need to upload ssl on nginx for www.example.com or myserver.mydomain or its IP adddress
Ok as per your comment if you want the SSL from the server side too. Then this are the two steps you need to follow.
Upload SSL for "www.example.com" on you server and configure nginex to server 443 port.
Change the ELB listeners from 443-80 to 443-443.
And it will work
I am running NodeJS app on EC2 instance on port 3000 without having any apache or nginx. I have setup ELB at front with SSL enabled( ACM on ELB ). Now I want to open my web-app url with https always.I have redirected port 443 request to port 3000 which is open on https. Same I want to do with port 80 request to go with 443 and then finally end up to port 3000, Because if someone request with port 80 for the web-app url that should also redirect to https and then end up on port 3000.
So Can you tell me How can I implement on ELB this thing for port 80 request which also open with https. My port 3000 is on http on EC2 instance.
port 443 https ----> port (3000) http ( its working )
port 80 (http) ---->want to open with https(443 ) ----->port(3000 ) http (this I want to implement)
I'm afraid ELB doesn't have built in support for this feature. It's something your web app would need to deal with.
You could set the ELB to forward port 80 to port 3000 too, and then in your app you'd need to inspect the X-Forwarded-Proto header; if this is not https then you would issue a redirect to port 443.
Amazon's X-Forwarded Docs
for solution to this, we need to run something on port 80 that could be sample nodeJS app or any default web-page(html or php) and then redirect port 80 request to port 443 and port 443 will redirect to port 3000(setup inside aws ELB) which is running actual NodeJS app.
