AWS - VPC Endpoint

-

 

A VPC endpoint enables customers to privately connect to supported AWS services and VPC endpoint services powered by AWS Private Link. Amazon VPC instances do not require public IP addresses to communicate with the resources of the service.

 

A VPC endpoint enables connections between a virtual private cloud (VPC) and supported services, without requiring that you use an internet gateway, NAT device, VPN connection, or AWS Direct Connect connection. 


We will create two subnets Public and Private. We will test the S3 bucket access from both the subnets.



Since the public subnet is connected to the Internet Gateway we should be able to access the S3 buckets from the EC2 instances launched in the Public Subnet.



We will try to access the s3 bucket from the Private Subnet.



Now, We will create a VPC Endpoint - S3.




Next, We need to select the VPC. I created a VPC called "DemoVPC" with Public and Private Subnets.



Next is the important thing. Route Table - VPCE.



Our intention is to allow EC2 instances on Private Subnet to access S3 Buckets. So, we need to add the route table for the Private Subnet.



We are all set. Let's try to access the S3 buckets from the private subnet EC2 instance.



It works. Yay!!!

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  ...
