currently my websocket traffic is delivering from gcp load balancer to nginx to websocket server. am planning to remove one hop so that if i remove nginx. Then how to configure my websocket port (Reserved port) to gcp load balancer so that my websocket traffic will come from gcp load balancer.
Is GCP load balancer support libwebsocket?
Can i configure my own port at GCP load balancer (except 443/80)
I have created a Load Balancer setup today which supports WebSockets with the new TCP SSL Proxy Load Balancer from GCP.
Here's how:
You need to use SSL on the frontend configuration with your SSL
certificate.
Then you need to have a TCP backend configuration pointing to your instance group and correct WebSocket port on your server.
You need to have session affinity enabled on the backend configuration.

We are using rancher docker orchestration tool: it is using HAProxy for enabling load balancing.
I am wondering how how a hanshake is processed if a new HTTPS connection to a service is established.
Is the the handshake done between client and the load balancer (rancher/HAProxy) or will the load balancer just forward the HTTPS requests to the backend service?
It depends how you configure it.
SSL Termination the handshake is done by the load balancer.
SSL pass-through the handshake is done by the backend.
I am trying to configure my website to have a secure connection (https://) via Amazon's EC2, ELB, and Route 53.
I am running a t2.micro instance (no Elastic IP or anything). My Elastic Load Balancer has the SSL certificate attached. My SecurityGroup allows for https connections through port 443. I'm not sure what I'm doing wrong here.
All of my configurations are below. Any help is appreciated because, as it stands, I can't access my website at all.
Thank you in advance!
EC2 - - -
Load Balancer - - -
Route 53 - - -
Step 1: Hit the EC2 instance directly and verify that the health check URL responds with an HTTP 200 status code. If not, then get that working first.
You aren't clear about your security group configuration. You should have a security group on your load balancer that allows HTTP and HTTPS connections. Then you should have a security group on your EC2 instance that allows HTTP (port 80) connections from the load balancer's group.
The issue is obviously the failing health check on the load balancer at this point, so no need to look at Route 53 settings right now. You need to concentrate on getting the communication working between the EC2 instance and the load balancer to get that health check to start working. Until then the load balancer won't accept any traffic because it doesn't have instances it considers healthy that it can forward traffic to.
I have a load balancer in front on an ec2-Classic instance. I have checked that the load balancer is working properly by directly linking to the DNS Name value that is listed in the Description tab for my load balancer. This gives me the main page of the webpage that lies on the EC2 instance. Thus my load balancer is working. My load balancer and my EC2 instance are in the same avalibility zone.
My load balancer has set up an SSL certificate and I have two listeners setup to forward http (port 80) and https (port 443) to instance port 80 as http. My EC2 instance has a security group set to accept http and https with protocol TCP on ports 80 and 443 respectively. Although my understanding is that only the port 80 would be useful, right? The data for the certificate are in the pem format. I have addded to my instance security group a custom TCP on Port Range 0 - 65535 for amazon-elb/amazon-elb-sg. This did nothing.
I can access my site using http just fine. If I try to access using https then I get Error code: ERR_CONNECTION_REFUSED on Chrome and Unable to Connect on Firefox.
I have checked similar posts for this question and nothing seems to help.
Any help or ideas would be greatly appreciated. Thanks
Have you made sure that the ELB is in a security group that allows https on port 443?
I had a similar problem with both classic and advanced load balancer. The thing that was missing for me is that the https to http translation stuff only workers AFTER you make an A record in the DNS for the domain your SSL is on ALIASED to the load balancer you just created. Once I did that all was well through that new A record DNS. Your instance doesn't need to accept port 443 and your LB definitely should not be forwarding over 443.
Hopefully it is something straightforward like this for you as well.
Wait, what SSL certificate in PEM format? I used an Amazon SSL certificate I just got from the dropdown. Are you sure you used an SSL certificate?
In your description I see that maybe you are not following Step 6 from Amazon's "Elastic Load Balancing in Amazon EC2-Classic ->Create HTTPS/SSL Load Balancer
Using the AWS Management Console -> Configure Listeners" guide.
There, it says that you should configure "HTTPS (...) in the Load Balancer Protocol [and] HTTPS (Secure HTTP) (...) in the Instance Protocol box.", whereas in your configuration you are forwarding ELB's 443 to port 80 in the instance.
For further reference, this is the guide that I'm talking about DEAD LINKhttp://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/configure-https-listener.htmlDEAD LINK
Also, check if your SSL certificate is well built according to the rules specified here: http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/ssl-server-cert.html
I have a problem to add https to my EC2 instance and maybe you guys can have the answer to make it work.
I have a load balancer that is forwarding the connection to my EC2 instance, I've add the SSL certificate to the load balancer and everything went fine, I've add a listener to the port 443 that will forward to the port 443 of my instance and I've configured Apache to listen on both port 443 and 80, now here the screenshot of my load balancer:
The SSL certificate is valid and on port 80 (HTTP) everything is fine, but if I try the with https the request does not got through.
Any idea?
Cheers
Elastic Load Balancer can not forward your HTTPS requests to the server. This is why SSL is there : to prevent a man in the middle attack (amongst others)
The way you can get this working is the following :
configure your ELB to accept 443 TCP connection and install an SSL certificate through IAM (just like you did)
relay traffic on TCP 80 to your fleet of web servers
configure your web server to accept traffic on TCP 80 (having SSL between the load balancer and the web servers is also supported, but not required most of the time)
configure your web servers Security Group to only accept traffic from the load balancer.
(optional) be sure your Web Servers are running in a private subnet, i.e. with only private IP addressed and no route to the Internet Gateway
If you really need to have an end-to-end SSL tunnel between your client and you backend servers (for example, to perform client side SSL authentication), then you'll have to configure your load balancer in TCP mode, not in HTTP mode (see Support for two-way TLS/HTTPS with ELB for more details)
More details :
SSL Load Balancers : http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/US_SettingUpLoadBalancerHTTPS.html
Load Balancers in VPC :
http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/UserScenariosForVPC.html
Do you have an HTTPS listener on your EC2 instance? If not, your instance port should be 80 for both load balancer listeners.
Background:
I had 1 instance created for EC2
I had my domain pointing to this instance
I had SSL installed for this instance (things were running great)
Furthermore:
I opted to create a second instance (using custom AMI from first instance)
I create a load balancer (things were working great -- from what i can tell...)
Question:
Why do I need to install the SSL certificate on the load balancer when it seems to have already been working?
I would presume when you say load balancer, you are refering to AWS ELB. If this is no the case, then disregard my answer.
Well the Best practice is to install SSL certs on load balancer and do the SSL termination there. Let the load balacner do SSL encryption/decryption so that your web server can do what they do the BEST...serving hte web pages.
Why do I need to install the SSL certificate on the load balancer
Now, technically You set is fine and you don't have to install SSL on load balancer. But then you have to use TCP Load Balancing feature of AWS ELB where in ELB will simply accespt traffic on 443 and will forward it to Web servers on 443. And then let your web servers do the SSL work.
I think this what you are looking for.
