AWS Private VPC + Terraform

-

 

Public Subnet

A public subnet is a subnet that is associated with a route table that has a route to an Internet gateway. This connects the VPC to the Internet and to other AWS services.

Private Subnet

 A private subnet is a subnet that is associated with a route table that doesn’t have a route to an internet gateway. Instances in the private subnet are backend servers they don’t accept the traffic from the internet.

I am going to create a private subnet via AWS console and refer that subnet IP in the terraform file to launch an EC2 Instance.











# Terraform Block
terraform {
  required_providers {
    aws = {
      source  = "hashicorp/aws"
    }
  }
}
# Provider Block
provider "aws" {
  profile = "default" # AWS Credentials configured via AWS CLI.
  region  = "us-east-1"
}

# Resource Block
resource "aws_instance" "ec2demo" {
  ami           = "ami-0b5eea76982371e91" # Amazon Linux in us-east-1
  instance_type = "t2.micro"
  subnet_id = "subnet-0ce1a2e3f8f5bd851"
  tags = {
    "Name" = "webserver"
  }
}

AWS Code Commit - CI/CD Series Part 1

-
Image
  This is a multi-part series to show how to implement a CI/CD pipeline in AWS. In this post, We will see how to use AWS Code Commit. AWS CodeCommit is a fully managed source control service that allows you to store and manage your code securely in the cloud.  It provides a private Git repository for your code and supports all Git commands and workflows. CodeCommit also integrates with other AWS services like AWS CodePipeline and AWS CodeBuild, allowing you to automate your entire software release process. This can help you streamline your development workflows and improve the overall efficiency of your team. I created a repo from AWS CodeCommit -> Create Repository. And I begin with cloning the repo locally. So that I can make changes and push it. To clone the repo click on "HTTPS" under Clone URL. I make changes to index.html file. Now push it to AWS CodeCommit. Let’s verify the changes in AWS Code commit. Changes are reflected in AWS CodeCommit. We are done with Part ...

Docker - Preventing IP overlapping

-

  What is IP address overlapping? When the container IP address overlaps with another IP external, then the application running on the container is not accessible from outside due to the IP address overlapping.  NOTE: This IP address overlapping can happen on the bridge interface IP or docker container IP. Let's see how to address this IP overlapping issue on the bridge interface. I already have a running container.  root@demo:~# docker run -d --name web --network mynet1 nginx:alpine 268647e11011d513d2357ce1c81e0f48787038a83d01d028d31a5b29dbdb885b root@demo:~# docker container ls CONTAINER ID   IMAGE          COMMAND                  CREATED         STATUS         PORTS     NAMES 268647e11011   nginx:alpine   "/docker-entrypoint.…"   4 seconds ago   Up 3 seconds   80/tcp  ...
