Set up a custom domain on heroku - ruby-on-rails

I have tried googling around but not quite found a solution to my problem. I have a domain already http://name.example.com. I have an app hosted on heroku http://app.herokuapp.com. I want to set up using WHM/CPANEL. I have already added the subdomain on heroku as described on their docs
heroku domains:add www.name.example.com
Running heroku domains outputs both url
=== myapp Domain Names
myapp.herokuapp.com
www.name.example.com
Heroku says from then on configure your DNS with a CNAME record pointing the subdomain to your app’s Heroku herokuapp.com hostname. I actually don't know how to proceed from here from the whm/cpanel. Anyone with previous experience on how to do this?
THanks

What provider you are using for you domain? It's very easy.
You need to login into your domain provider site and create a a DNS record.
If you are using some good domain provider you can get some screen shot helps online.

How to do DNS Set up / cname flattening with heroku and Godaddy

I have application deployed in Heroku with Godaddy domain.
After trying several methods done dns setup.
Add CNAME www with value DNS target provided by heroku.
This is working fine for domain with www. But I like to open domain without www(naked domain). which is not working currently.
What I have already tried and nothing worked for me.
Add CNAME with name(naked domain) and value(heroku app url)
(a) Add a Domain with naked domain name(domain name without www)
(b) Add CNAME with name(naked domain) and value(heroku app DNS Target
value from(a))
Add Forwarding https:// with www.domain-name
Then tried configure DNS setup in cloudflare there everything problems got resolved, But there website's speed got slow and even some JS was not working. Tried several code changes and deployment, Nothing worked so finally back to GoDaddy for DNS Setup.
Somewhere got to know that CloudFlare provide CName flattening which GoDaddy not. Due to CName Flattering Redirection works fine with CloudFlare.
Please suggest me steps to resolve this. domain URL
Got response from Heroku team.
Redirecting from root domain [http://mysite.in/] to sub domain [http://www.mysite.in/] can be done at application level or on your DNS provider [GoDaddy] settings. Heroku or any other similar platforms won't have such an option.
Heroku recommends you to point the root domain to its DNS target with an ALIAS/ANAME record type. Unfortunately, Godaddy doesn't give that option. The root domain's DNS target can be an IP address as well, but the IP addresses of your application on Heroku keeps changing, at least once a day, so you can't use that as DNS target. We have an article on how you should set up the domains for a Heroku app, please give it a read https://devcenter.heroku.com/articles/custom-domains and let me know if you have any question there.
So the options you are left with is to make use of an add-on like Quotaguard which will give you a static IP address against your Heroku application, this IP can be used as DNS targets or change the DNS provider, we have a list of DNS providers which support ALIAS/ANAME record type.

1&1 domain pointing to Heroku

I am aware that there have been a few discussions on this one but none have given a definitive answer. I am hoping this will help me and others.
Problem:
I have a domain name (www.xyz.com) registered with 1&1.
I want users to be able to type this in and be shown my website. A Heroku web app.
I want the domain name (www.xyz.com) to be displayed. Not any subdomain url or the heroku app URL.
I do not want the set-up do be anything that will have a detrimental impact on SEO.
Note: I have just got off the phone with 1&1 and they have said that my only options are to do a frame redirect or a http forward. Neither of these meet the above requirements.
Additionally, other posts have suggested finding out what the Heroku IP address is and using this but Heroku recommend against this as they might change it without notice.
Please could I ask that any one kind enough to respond spells things out a little. Anyone having problems with redirects is likely to be new to this.
Thanks.
never used the 1&1 services, but solving your problem is pretty straightforward.
Take the following steps:
Add you domain to heroku. heroku domains:add www.xyz.com . If you have more than 1 app in your heroku account, remember to pass the --app flag
Now you should have something like myherokuapp.herokuapp.com where myherokuapp is the name of your app on heroku
Go to 1&1 and create a CNAME record pointing to myherokuapp.herokuapp.com
I found this video to be helpful - https://www.youtube.com/watch?v=ZLVBBAnrrL4
Basically, as noted by #Kevin Lawrence above, you use the 'www' subdomain.
I've never used 1&1 but my DNS provider (dreamhost) does not allow CNAMEs on the main domain name either. It does however allow me to create a CNAME for the www subdomain which was good enough in my case.
I did this:
heroku domains:add www.mydomain.com
create a CNAME record pointing to mydomain.herokuapp.com
Have mydomain.com redirect to www.mydomain.com
It's not exactly what I wanted (or what you want) but it works.
What worked for me was to user Namecheap.com's FreeDNS service that provides free automatic redirect for your TLD and subdomains directly to Heroku, while keeping your domain visible:
example.com and www.example.com now point to exampleapp.herokuapp.com
I had to have a live chat with Namecheap's support to complete the domain verification process, but they answered really fast! Love to namecheap, 1and1 is really crappy, moving my domains away soon. :)
I got this to work properly! No need for CNAME at all. Create a A record in heroku like in this link - creating a custom room domain - provided by heroku (of course, change example.com to your root domain):
heroku domains:add example.com
Here, example.com is the ROOT domain. Once you get an A record, execute the following command
heroku domains:wait example.com
Now verify your domain has been provisioned:
heroku domains -a [your custom heroku app name]
And you get this:
=== [your custom app name] Custom Domains
Domain Name DNS Record Type DNS Target
example.com ALIAS or ANAME elliptical-blueberry-1euo3460fyrtc8zdgulv0f7o.herokudns.com
Next, get the IPv4 IP address of elliptical-blueberry-1euo3460fyrtc8zdgulv0f7o.herokudns.com I got it by using a lookup service.
Updating 1 and 1
Go to 1and1.
Click the DNS tab for your custom domain e.g. example.com
Delete the existing A record
Create a new A record and enter in the # symbol if it asks you, or else I think it is the default AND enter in the IPv4 address
For testing this out, make the TTL 1 min until it's stable
Give it time to propagate. Could be a few minutes to 24 hours.

Point Domain Registered Through iPage to Heroku App

I've got a domain (and hosting account) with iPage.
I'd like to point this domain example.com and www.example.com to my heroku app - which is currently available at example.herokuapp.com.
I've set up a CNAME (Alias) as follows:
host: www
points to: example.herokuapp.com
I've gone through Heroku's documentation for custom domain names; however, I've been unable to make it work.
What do I need to do differently?
The reason you are not able to access your site at www.example.com even after setting up the DNS correctly is you have not updated your application setting inside Heroku. You need to provide Heroku with the web address want to host your site, this you can do inside your Application Settings page.
Heroku does not support apex domain so you might want to setup a redirect from example.com to www.example.com, I don't see why you would want to run your site on two web address. But you really want to run your site on two addresses you can try zerigo dns addon on heroku. Zerigo dns can also help you setup the redirect.

How to point a domain at a heroku application

While I've done this on my VPS, I've never done this for a heroku application, and now I have to do it for a fairly large company so I really want a simple list of bullet-points in how to do this.
I've read these instructions, and I'm still a little bit unclear on what exactly they mean. Again, if I had more time I'd buy some rubbishy domain and test it myself, but I don't have time on my side and need to get this right first time!
Thankfully, no SSL is required at this time.
Here's what I can gather I need to do to point the url www.foobaryfoobs.com at my application, running at warm-chamber-1882.herokuapp.com. Please correct me:
1) I add www.foobaryfoobs.com to the local repository containing the application.
I presume I do this by navigating to the repository on my local machine and running:
$ heroku domains:add www.foobaryfoobs.com
How does this work? Does it update some configuration file somewhere that I need to add to the repository and then push up to heroku?
Are there any caveats or best practices here? What other domains should I add? heroku domains:add *.foobaryfoobs.com, for example?
Heroku advises we use the above wildcard domain here. Why?
2) Log into the registrar that created www.foobaryfoobs.com and navigate to its control panel.
3) Update the domain's CNAME record to point at warm-chamber-1882.herokuapp.com
Am I done for the most part? Now do I just wait?
Is there no IP related stuff?
The domain has several dozen emails attached to it. As long as I don't touch the MX record, I should be fine?
What's a root domain? Why should I add it?
Why should I care that:
Some DNS hosts provide a way to get CNAME-like functionality at the
zone apex using a custom record type.
4) Update the domain's FORWARD / URL record so that foobaryfoobs.com points to www.foobaryfoobs.com
For a nooby, please explain why this is necessary.
3 Conclusive Questions:
1) Is this how it should be set up?:
The app:
warm-chamber-1882.herokuapp.com
Should have the following configurations (saved in some weird config file that I wouldn't mind knowing more about about):
domains:
www.foobaryfoobs.com
*.foobaryfoobs.com
The domain:
www.foobaryfoobs.com
Should have the following records:
CNAME: warm-chamber-1882.herokuapp.com
URL / FORWARD: foobaryfoobs.com target: www.foobaryfoobs.com
MX: *as long as I don't touch them the emails will still work*
2) Am I covered against:
It’s important to make sure your DNS configuration agrees with the
custom domains you’ve added to Heroku. In particular, if you have
configured your DNS for *.example.com to point to
example.herokuapp.com, be sure you also run heroku domains:add
*.example.com. Otherwise, a malicious person could add baddomain.example.com to their Heroku app and receive traffic intended
for your application.
3) How should I adjust the steps for a site that has an SSL backend section?
A.
$ heroku domains:add www.foobaryfoobs.com
How does this work? Does it update some configuration file somewhere that I need to add to the repository and then push up to heroku?
I dont know exactly how does it works internally but this command is equivalent of adding ServerName in apache config file, without this when request comes to www.foobaryfoobs.com it will be forwarded to heroku because of dns but heroku fail to determine your app. You will see the below image.
That's why they need your domain so they know which apps belongs to which domains. They also need it for domain precedence purpose. No changes are required in your code as long as you are okay to allow your user to access Heroku subdomain ie warm-chamber-1882.herokuapp.com. If you dont want user to access heroku subdomain you have to pass 301 http status so it will be redirected to your actual domain i.e www.foobaryfoobs.com . For this you have add this in your application controller
before_action :forward_to_domain_if_heroku_subdomain
private
def forward_to_domain_if_heroku_subdomain
if request.host == 'warm-chamber-1882.herokuapp.com'
redirect_to "http://www.foobaryfoobs.com" , status: 301
end
end
Are there any caveats or best practices here? What other domains should I add? heroku domains:add *.foobaryfoobs.com, for example?
if you ONLY want to use www.foobaryfoobs.com as your domain, this command is suffice ie
heroku domains:add www.foobaryfoobs.com
If you want to assign naked domain foobaryfoobs.com then you ALSO have to run
heroku domains:add foobaryfoobs.com
If you application use subdomains like subdomain.foobaryfoobs.com then you also have to run
heroku domains:add foobaryfoobs.com
2) Log into the registrar that created www.foobaryfoobs.com and navigate to its control panel.
To be precious, you have to do DNS management tool.
3) Update the domain's CNAME record to point at warm-chamber-1882.herokuapp.com
Yes.
Am I done for the most part? Now do I just wait?
Yes, but there are also other things.
Is there no IP related stuff?
Yes, there is no ip related stuff.
The domain has several dozen emails attached to it. As long as I don't touch the MX record, I should be fine?
Yes.
What's a root domain? Why should I add it?
if you want to accept requests from user at warm-chamber-1882.herokuapp.com (not www. warm-chamber-1882.herokuapp.com) then you have to add it.
Why should I care that:
Some DNS hosts provide a way to get CNAME-like functionality at the zone apex using a custom record type.
Yes. They are talking about ALIAS or ANAME type of records. (DNSimple provides it). You have to care it because from that custom-record-type it is easily to add record. They are like pre defined templates eg ALIAS is template of A record.
4) Update the domain's FORWARD / URL record so that foobaryfoobs.com points to www.foobaryfoobs.com
For a nooby, please explain why this is necessary.
It is necessary because www.foobaryfoobs.com and foobaryfoobs.com are different in a same way like images.google.com and news.google differs. www is nothing special it is just a subdomain. If you dont do this, user can't use your site from foobaryfoobs.com but can access www.foobaryfoobs.com.
B.
1) Is this how it should be set up?
Yes, it is correct. But if you want to allow foobaryfoobs.com and www.foobaryfoobs.com, you have to do something like below table. You dont require *.foobaryfoobs.com record if your app doesn't use any subdomain except www. It is bad practice actually to add *.foobaryfoobs.com .
Type | Name | Content
---------------------------------------
ALIAS | foobaryfoobs.com | yoursite.herokuapp.com
CNAME | www.foobaryfoobs.com | yoursite.herokuapp.com
It’s important to make sure your DNS configuration agrees with the custom domains you’ve added to Heroku. In particular, if you have configured your DNS for *.example.com to point to example.herokuapp.com, be sure you also run heroku domains:add *.example.com. Otherwise, a malicious person could add baddomain.example.com to their Heroku app and receive traffic intended for your application.
Yes. Moreover you dont have to worry about this. If the malicious user can set subdomain at your domain then he capable to do much destruction :P. Actually, malicious user can't access your DNS management tool so you're safe.
In your registrars host records you want to set the # to the redirect to the www.foobaryfoobs.com and the www record to the CNAME of warm-chamber-1882.herokuapp.com, this is because Heroku may change the IP address associated with that hostname and if you have the ip in your registrar you would also have to update. Using a CNAME ties that url to the ip so when Heroku updates the ip your site is still up. As long as you don't touch your MX records your email will be fine.
To protect again *.foobaryfoobs.com issues they warn about you can also setup a host record for exactly that and make it a CNAME as well pointing at warm-chamber-1882.herokuapp.com.
As far as setting up the SSL you can look at this article, that should get you setup.
I can answer only some of this:
1) a) It updates some config stored on heroku's end related to your app. You can see that if you login to the heroku site and look at the config for your app.
b) dunno
c) this will let people type both "http://www.foobaryfoobs.com" and "http://foobaryfoobs.com" and for both of them to go to your app.
You can also do this with an A/AAAA record.. in my opinion the better way.

Heroku EU region how to setup custom domain name?

What is the nameserver to use for heroku?

I am hosting my app at heroku, my domain is with godaddy. How to point my domain to my heroku app?
Shall I change NameServer 1 and NameServer 2 to myApp.herokuapp.com and myApp.herokuapp.com?
I have followed instructions at heroku, but, I want to make sure that I am on the right way.
You don't change the nameservers, Heroku is not a DNS provider. You leave the domain management wherever you are comfortable with it and edit the records to point at your app on Heroku.
It's detailed more at https://devcenter.heroku.com/articles/custom-domains#dns-setup but in summary, if you have a domain foobah.com registered with GoDaddy with would use their control panel (maybe Advanced control panel) to edit the DNS records to point at Heroku. You need to have a CNAME record for www.foobah.com with it's value set to myapp.herokuapp.com. You may find you already have an A record setup for you when you registered the domain or an existing site, you should delete this. You also then need to add the custom domain www.foobah.com to your application on Heroku.
