Terraform Aws Wordpress with Private Database

HellO EveryOne ..!!

Task DescripTion :-

# Performing the following steps:1. Write an Infrastructure as code using terraform, which automatically create a VPC.2. In that VPC we have to create 2 subnets:1. public subnet [ Accessible for Public World! ]2. private subnet [ Restricted for Public World!3. Create a public facing internet gateway for connect our VPC/Network to the internet world and attach this gateway to our VPC.4. Create a routing table for Internet gateway so that instance can connect to outside world, update and associate it with public subnet.5. Create a NAT gateway for connect our VPC/Network to the internet world and attach this gateway to our VPC in the public network6. Update the routing table of the private subnet, so that to access the internet it uses the nat gateway created in the public subnet7. Launch an ec2 instance which has Wordpress setup already having the security group allowing port 80 sothat our client can connect to our wordpress site. Also attach the key to instance for further login into it.8. Launch an ec2 instance which has MYSQL setup already with security group allowing port 3306 in private subnet so that our wordpress vm can connect with the same. Also attach the key with the same.Note: Wordpress instance has to be part of public subnet so that our client can connect our site.mysql instance has to be part of private subnet so that outside world can’t connect to it.Don’t forgot to add auto ip assign and auto dns name assignment option to be enabled.
  • A AWS Account .
  • A IAM User On aws so that using its credential we can create a profile t login and can use it in future

terraform init# It will install plugin rewuired for our code
terraform validate# it will validate our code is their any or not if not then we can go ahead
terraform apply --auto-approve
terraform destroy --auto-approve# This will destroy our entire environment that we created !!
