i had issues while creating a VPC in terraform. it kept giving me error while creating it

hi, I checked your code you made small mistakes in CIDR block allocation, VPC resource creation, etc. Here am updated your code. Pls check and test your environment and close to the issues. Note:Commented with mistakes portion Solution.txt

provider "aws" { region = "us-east-1" }

creaeted VPC

resource "aws_vpc" "vijayvpc" { cidr_block = "10.0.0.0/16" tags = { Name = "TestVPC" }

Note your CIDR bloc and Subnet have same values so it' can't able to create you gave vpc and subnet have same CIDr/24 bcoz it's overlapping

}

create with Public Subnet

resource "aws_subnet" "pubsub" { vpc_id = "aws_vpc.vijayvpc.id" cidr_block = "10.0.1.0/24" }

create with private subnet

resource "aws_subnet" "privsub" { vpc_id = "aws_vpc.vijayvpc.id" cidr_block = "10.0.2.0/24" }

resource "aws_route_table" "pubRT" { vpc_id = aws_vpc.vijayvpc.id

route { cidr_block = "0.0.0.0/0" gateway_id = aws_internet_gateway.newgw.id

} }

associating the public RT with the public subnets

resource "aws_route_table_association" "pubRT" { subnet_id = aws_subnet.pubsub.id route_table_id = aws_route_table.pubRT.id

}

/resource "aws_route_table_association" "pubRT" { subnet_id = "aws_subnet.pubsub.id" route_table_id = "aws_route_table.pubRT" }/

associating the Private RT with the Private subnets

/resource "aws_route_table_association" "PrivRT" { subnet_id = "aws_subnet.vijayprivsub.id" route_table_id = "aws_route_table.privRT.id" } /

resource "aws_route_table_association" "PrivRT" { subnet_id = "aws_subnet.privsub.id" route_table_id = "aws_route_table.PrivRT.id" }

Create InternetGateway

resource "aws_internet_gateway" "newgw" { vpc_id = aws_vpc.vijayvpc.id tags = { Name = "New InterNet Gateway" } }

Create EIP for the IGW

resource "aws_eip" "new-EIP" { vpc = true tags = { Name = "new-EIP" } }

resource "aws_nat_gateway" "natgt" { allocation_id = aws_eip.new-EIP.id subnet_id = aws_subnet.pubsub.id

 tags = {
Name = "gw NAT"

}

}
