I am running my website on AWS.
I have one load balancer for my two web servers. My load balancer doesn't have a static IP address, it has a domain name.
I want my traffic to come only via the load balancer. I am using Cloudflare's DNS instead of Route 53, because that's what the Cloudflare instructions said.
I cannot add the load balancer's IP as an A record because it is dynamic and cannot be added through Cloudflare's DNS panel (Not like Route 53). Help me I am stuck in this situation. No solution is offered by Cloudflare so far.
Has anyone faced the same issue?
You can set your Cloudflare record as a CNAME alias of your ELB's A record
See:
https://support.cloudflare.com/hc/en-us/articles/200168986-How-do-I-add-a-Amazon-ELB-Elastic-Load-Balancing-record-to-CloudFlare-
I suggest to manage your domain DNS with CloudFlare.
Add a CNAME record for your subdomain demo which points to that IP.
On CloudFlare Console go to Crypto > Origin Certificates. Create a new one with RSA, then import it to AWS Certificate Manager at us-east-1. For the certificate chain use this.
Be sure that Always use HTTPS in Crypto tab is on.
After some minutes you should be using your domain pointing to AWS with HTTPS working fine.
That's what I did to make a subdomain to work with an AWS API endpoint with SSL.
I decided like this:
I created in the cloudflare, in the DNS table, two CNAME records that point to the dns name of the load balancer generated in aws.
The first record created must contain in the "Name" field, the value "www" with the "content" field pointing to the url of the load balancer in aws. The second record, on the other hand, points to root, containing the value "#" in the "Name" field and "Content" pointing to the same load balancer server in "aws".
See the images below for a better understanding.
I've tried with the Cname record with target as Load Balancer DNS name, but the website is not secured.
If you need static IP for your Load Balancer then use Global Accelerator. It will provide you a static IP. After that create an A record with domain name in cloud flare and content with your Static IP provided by Global Accelerator and the Proxy status must be Proxied.

Currently my domain name adthrone.com is pointed to ec2 instance ip 5x.xx.xx.xx
That domain result is HTTP
So I created a load balancer with this link https://adthrone-loadbalancer-1188159040.us-west-2.elb.amazonaws.com/
Now, Is that even possible to change the DNS pointing of
5x.xx.xx.xx
to this
https://adthrone-loadbalancer-1188159040.us-west-2.elb.amazonaws.com/
I tried to contact my DNS Provider BlueHost. But they seems do not want to change it. Because on my bluehost screen. If I manually change it. From EC2 IP to Load Balancer there is an error that the link is not applicable.
The load balancer is working fine, it has only mixed content that needed to fix. But the issue is that possible to change the DNS pointing from IP to Link?
Use a CNAME record instead. You can put adthrone-loadbalancer-1188159040.us-west-2.elb.amazonaws.com in the value field of the CNAME record.
I have set up a static website using GCP Bucket Storage and loaded SSL certificate using HTTPS Load Balancer. My DNS record is set to: CNAME pointing to to bucket with www, (c.storage.googleapis.com) and A record to the Load Balancer Proxi IP with #. When I go to the website using http protocol I get a 404.
Am I missing something?
I have tried to see if there was a way to reconfigure the DNS and the bucket but couldn't find a way.
I hope to be able to get both http and https versions to work
I've created a Cloud DNS Zone for example.com and pointed it's A record to Load Balancer's Static IP.
In the Load balancer, I have configured foo.example.com to point to the foo-backend-service:
When I navigate to foo.example.com, it doesn't work.
Do I need to explicitly create an A record entry for foo.example.com in the Cloud DNS Zone and point that to the Load Balancer's Static IP.
The domain names example.com and foo.example.com are different DNS names. Therefore you need to create DNS resource records for each one.
If you plan to keep example.com and foo.example.com pointing to the same load balancer, use a CNAME mapping foo.example.com to example.com. Otherwise create an A record with IP addresses pointing to the load balancer.
In your question you are showing your backend rules. Unless you need to specify rules for mapping urls, delete the extra entries and just use the default rule (I cannot see the right hand side so I don't know what you are trying to accomplish). I think you were trying to map foo.example.com to example.com which is not usually correct in your case.
I had a question about using the URL in my Load Balancer - and using it as the A Record for my DNS entry via GoDaddy...GoDaddy doesn't allow a URL, and insists on the A Record being an IP address and no other format. But I don't see this option available in the Load Balancer I created, only a URL.
What I have so far is this..
I've created a Load Balancer successfully using both HTTP and HTTPS, along with the RapidSSL cert I purchased and imported.
When I open my new Load Balancer item in EC2 dashboard, under the Description tab, I see an auto-generated URL next to DNS Name: http://ACThttp-617756314.us-east-2.elb.amazonaws.com (A record)
The above URL works fine in my browser. I went to plug this into GoDaddy'a A record in the DNS settings --- but apparently GoDaddy only allows an IP address to be used as an A Record...and not a URL like the one generated by EC2. I find this confusing since it literally says "A Record" next to this generated URL in my Load Balancer.
Does this mean I need to generate an IP Address inEC2 dashboard, so that I can use it in GoDaddy DNS settings? I'm guessing this is done via Route53...or could I skip this altogether and still find a way to connect my new Load Balancer to my DNS A record some other way?
However this is done, any help would be appreciated. If Route53, what are the exact steps I need to take? Or any other solutions, as much detail you could provide would be so so so helpful.
I've done this a few times successfully in the past, but it was a while ago and I can't recall how I connected them to the DNS properly.
Thanks!
You should use a CNAME record (not an A record).
A CNAME record points to another DNS name, whereas an A record points to an IP address.
Load Balancers should always be addressed by their DNS Name, so use a CNAME record.
I have a web service running on EC2 behind an elastic balancer. I would like to allow my clients to point their A record to my web service so they could have their domain on my server. Similar to shopify or github pages.
However, I don't want to give them the IP of the web service, I'd like the request to go though the load balancer. How can I achieve this? Should I create a small server to forward requests? How does that work?
Many thanks!
If you are running your service behind an Elastic Load Balancer, you usually do not want to use ELB DNS name (which is something like your-service-ELB-1122334455.us-east-1.elb.amazonaws.com). Instead you will configure (probably using Route53, but any DNS service will do) CNAME or ALIAS record with some friendly name, like yourservice.yourdomain.example (this way, name will be easier to remember, and you have the freedom to change load balancer if needed).
All your customers have to do is to create CNAME DNS record pointing their name to your friendly service DNS name, like:
foo-service.theirdomain.example CNAME yourservice.yourdomain.example.
You also need to be aware that HTTP requests will have Host: header containing name entered by user (in case your server/service relies on that info)
You need to consider using Route53 as your clients's DNS service provider might not be supporting this feature beacuse of DNS rule.
See s3.6.2 of RFC 1034
Amazon created a new aliasing system for Route 53. You can now map the apex of a hosted zone to an Elastic Load Balancer using an Alias record. When Route 53 encounters an Alias record, it looks up the A records associated with the target DNS name in the Alias, and returns the IP addresses from that name.
In order to allow all of our customers to benefit from this new feature, there is no charge for queries to alias records when the target is an Elastic Load Balancer.
Associating Your Custom Domain Name with Your Load Balancer Name.
You can also create a Subdomain That Uses Amazon Route 53 as the DNS Service without Migrating the Parent Domain.
