DNS In the present cloud-based infrastructure conditions, managing DNS (Domain Name System) configurations is vital for coordinating traffic effectively across different services and resources. AWS Route 53 stands apart as a highly versatile and dependable DNS web service given by Amazon Web Services, offering developers and administrators the capacity to manage domain names and route internet traffic effortlessly and efficiently.
Terraform, then again, is an infrastructure-as-code apparatus that empowers automated provisioning and the board of cloud infrastructure resources. By utilizing Terraform’s declarative way of dealing with characterizing infrastructure arrangements, users can make reproducible and version-controlled infrastructure arrangements, wiping out manual intercession and decreasing the risk of design float.
While consolidating AWS Route 53 with Terraform, associations can automate the executives of DNS configurations, simplifying it to keep up with and update DNS records, oversee traffic steering strategies, and ensure high accessibility for their applications and services. This mix considers the consistent consolidation of DNS across the board into the infrastructure as-code work process, advancing consistency, reliability, and versatility in cloud arrangements.
Understanding Primary Terminologies
- AWS Route 53: Amazon Web Services Route 53 is an exceptionally versatile and available Domain Name System (DNS) web service utilized for managing domain names and routing web traffic to AWS resources and different endpoints.
- DNS (Domain Name System): DNS is a various leveled and dispersed naming framework used to translate human-readable domain names (e.g., geeksforgeeks.com) into IP addresses (e.g., 192.0.2.1) that PCs can understand. DNS assumes a vital role in exploring the internet by planning domain names to relate to IP addresses.
- Records: DNS records are information sections inside a DNS zone document that map space names to explicit IP addresses or other DNS records. Normal kinds of DNS records incorporate A records (IPv4 address), AAAA records (IPv6 address), CNAME records (canonical name), MX records (mail exchange), and TXT records (text records).
- Zones: With regards to AWS Route 53, a DNS zone refers to an assortment of DNS records under the managerial control of a particular association or individual. Each DNS zone compares to a space name (e.g., geeksforgeeks.com) and contains records that characterize how area names are set out to IP addresses.
- Terraform: Terraform is an open-source infrastructure as-code instrument created by HashiCorp. It permits clients to characterize and arrange foundation resources using definitive setup records. Terraform automates the creation, modification, and deletion of resources across different cloud suppliers and on-premises conditions.
What is AWS Route 53?
Route 53 is Amazon Web Services’ exceptionally adaptable and available Domain Name System (DNS) web service. It gives developers and administrators the ability to manage domain names and route internet traffic to different AWS resources and different endpoints.
Key features of Route 53 include:
- Domain Registration: Route 53 allows users to register and manage domain names directly through the service. By using Route 53 users can create their own domain name easily.
- DNS Management: Users can create and manage DNS records, for example, A, AAAA, CNAME, MX, TXT, and so on. to map domain names to specific IP addresses or other DNS records.
- Traffic Routing: Route 53 backings different routing arrangements, including simple routing, weighted routing, dormancy based routing, geolocation-based routing, and failover routing. These approaches empower clients to control how traffic is coordinated to various endpoints in light of elements like geographic area, latency, or health checks.
- Health Checking: Route 53 incorporates wellbeing really looking at capacities to screen the wellbeing and accessibility of endpoints. Clients can arrange wellbeing checks to screen the situation with their resources and consequently change steering in view of the outcomes.
- Worldwide Reach: With a distributed network of DNS servers found around the world, Route 53 ensure low-latency and high execution DNS resolution for users getting to resources internationally.
Step-By-Step Process to create AWS Route 53 Using Terraform
Step 1: Launch An Instance
- Launch an EC2 instance for this go to amazon console and login your credentials if already existing account is there other wise create account
- Now connect with git bash terminal or any terminal like powershell, putty, e.t.c. by using SSH Client
Step 2: Install Terraform
- Now install terraform packages by using following below commands
sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://rpm.releases.hashicorp.com/AmazonLinux/hashicorp.repo
Now install terraform by using following commands
sudo yum -y install terraform
Step 3: Create A File And Write Terraform Script for AWS Route 53 Using Terraform
Create a file with .tf extension in that file write a script by using following command
Provider configuration
This section specifies the AWS provider and sets the region to “us-east-1”. The provider block configures the authentication details and default settings for interacting with AWS.
provider "aws" {
region = "us-east-1"
}
Provider configuration
AWS Route Creation
This section defines an AWS Route 53 record resources named “example_record”. It indicates the setup for a DNS record inside the Route 53 zone recently made. The characteristics of the record include:
- zone_id: This characteristic references the ID of the Highway 53 zone where the record will be made. It utilizes the introduction sentence structure to get to the zone ID of the “example_zone” asset.
- name: This indicates the domain name for the record. For this situation, it’s example “www.geeksforgeeks.com“.
- type: This property characterizes the kind of DNS record. Here, it’s an “A” record, which maps a domain name to an IPv4 address.
- ttl: This characteristic establishes the Point in time to-Live (TTL) an incentive for the DNS record. It determines how long DNS resolvers should to cache the record, in a seconds.
- records: This determines the data related with the DNS record. For an “A” record, it normally contains at least one IPv4 address to which the space name should to determine.
resource "aws_route53_zone" "example_zone" {
name = "example.com"
}
resource "aws_route53_record" "example_record" {
zone_id = aws_route53_zone.example_zone.zone_id
name = "www.example.com" # add your desired domain name
type = "A"
ttl = "300"
records = ["1.2.3.4"]
}
AWS Route Creation
Step 4: Now Initialize Terraform And Execute Terraform Commands
- Now initialize terraform by using following command when we execute this command terraform install necessary packages into local machine.
terraform initterraform init
Now execute terraform execution commands by using following commands
terraform fmt # to format our script into canonical form
terraform validate # to validate either is there any syntax errors
terraform plan # it going to plan infrastructure to build
terraform fmt , terraform validate and terraform plan
- Now execute terraform apply command by using following command
terraform apply --auto-approveterraform apply –auto-approve
Here below we see that terraform apply complete and Two resources was created in AWS
The following screenshot shows that we successfully created a sqs topic in aws using terraform
