DNS Setup

Overview
Goals
The goal of this section is to get your DNS setup for your portal. For single server portals, this just requires A records and for multi-server portals, this requires A records and a load balancer.
Steps
Single Server Portal
1.Create Hosted Zone
2.Update name servers
3.Set A Records
Multi-Server Portal
1.Create Hosted Zone
2.Update name servers
3.Set A Records
4.Create API Keys
5.Setup Load Balancer
AWS
Currently, this documentation is set up to walk you through using AWS for your DNS management.

Hosted Zones
Once you have created an account and logged in, head to Route53. You can find this under Services or by searching for it in the search bar.
In Route53, click on Hosted Zones and create a new hosted zone. This hosted zone should be public and is the domain that you purchased for your portal.
Nameservers
Once your hosted zone is set up, AWS will have populated a nameserver NS record for your domain. Typically there are 4 nameservers listed in the NS record. You will need to update the nameservers for your domain where you purchased and managed your domain. 
If you happen to purchase your domain through NameCheap, you can update your nameservers by clicking on your domain, selecting the Custom DNS option under NameServers, and copying in the name servers that AWS generated for you.
A Records
Follow the steps to set up your A records for your server, either as a single server portal or as a multi-server portal.
Single Server A Records
After you have created your hosted zone, you can now create additional DNS records.
First, you will want to create an A Record that points from your domain to your server's IP address. 
Next, you will want to create a wildcard A record. To do this, you create an A record, select the alias option and find the A record that you just created that points to the server IP. For the value of Record name place an asterisk (*).
Multi-Server A Records
The process for setting A records for a multi-server portal is the same as for a single server portal, with the only change being the A record pointing to the server domain instead of the portal domain.
So if your portal domain is mydomain.com and you're setting up a server at sev1.mydomain.com, you would have an A record for sev1.mydomain.com pointing to the IP of the server and a wildcard A record for *.sev1.mydomain.com pointing to the first record sev1.mydomain.com.
CNAME Record
If you want your domain to be accessible at both mydomain.com and www.mydomain.com you will need to add a CNAME record for www that points to mydomain.com like so:
Verify
DNS records can sometimes take a while to update. However, you will know that everything is set up properly when you can ssh into your server with the domain name instead of the IP address, like so:
# Single Server Portal
ssh [email protected]
​
# Multi-Server Portal
ssh [email protected]
Load Balancer
If you are running a multi-server portal, you will need to set up a load balancer to load balancer your domain across your servers.
Access Key
The load balancer requires an access key, so you will need to generate an access key for your account.
Click on Security Credentials in your account dropdown menu.
Under Access keys, click Create New Access Key.
Save the information in the common.yml file you created in your portal-common-configs LastPass folder. The AWSAccessKeyID is the aws_access_key and the AWSSecretKey is the aws_secret_access_key.
