Setting up an AWS infrastructure using Terraform

SETUP YOUR PROFILE / SOFTWARE

• Firstly, you would need to create an IAM user (ishan_tf in my case). Note down the Access Key ID and Secret Access Key (you will need it to configure the profile on was cli).
• Create a key pair and a security group that allows inbound SSH and HTTP.
• Download the AWS cli and Terraform onto your system.

Use #aws configure --profile ishan_tf (profilename) and paste your access keys here.

Windows users can add the terraform path to environment variables, where as Linux users can simply unzip and #chmod +x terraform #mv terraform /usr/bin

NOW THAT WE HAVE OUR SYSTEM SET UP, LETS CODE!

(Create a .tf extension file)

• Create an S3 bucket and configure its policy to public-read.

• Configure Jenkins to get images from github to S3 bucket.

We need the S3 publisher plugin

Configure it

Create a job to transfer contents to the s3 bucket.

• We need to trigger this after our bucket is created.

• Create a CloudFront distribution.

• Remember to use the domain generated for your image src in HTML.
• Create an EC2 instance and install services like httpd PHP git.

• Create and attach EBS to it.

• Partition, format, and mount it to /var/www/html/ to make the data persistent. Also, clone the developers' code to the folder.

• We can also output or store the IP of the instance here.

• Now that we have set up the infrastructure code, let's run it.

#terraform init (initialize a working directory containing Terraform configuration files.)

#terraform validate (validates the configuration files in a directory).

#terraform apply (apply the changes required to reach the desired state of the configuration).

• And here it is!
