Auto tag AWS resources with Lambda

Automating AWS resource Tagging 

Why Tagging resources?

Tagging AWS resources is very important when you want to automate some tasks based on the tags, like you want to install patch automatically based on the tags from SSM association or you want to get a list of resources based on the tags. There are many aspects where tagging the resources will be required. 

In this blog, I will be showing on automatically adding a tag CreatedBy to the S3 bucket. You can leverage the same logic to other AWS resources.

Architectural design

S3 tag Automation design









 

AWS resources:

  • EventBridge
  • Lambda
  • Trail (CloudTrail)
In Cloud, event plays very important role in automation, Amazon EventBridge is a serverless event bus that makes it easier to build event-driven applications at scale using events generated from your applications, integrated Software-as-a-Service (SaaS) applications, and AWS services.

Steps:

  • Lambda Role required below permission
    • S3 bucket tagging permission
    • AWSLambdaBasicExecutionRole (Managed policy)
  • Create EventBridge rule with below configuration


Done, so we have configured trigger for lambda and when a new S3 bucket is created, automatically bucket tag will be applied. This tag helps to understand on who created the resources by seeing the tag.

Connect to Linux EC2 Instance if Key pair is lost after Initial Launch

By
Use Case We know that EC2 Linux instances are accessible through the private keys by default. However, SSH is allowed but you cannot use SSH password authentication to access Linux instance as it is disabled by default. So, what would happen if you lose the private key of your Linux instance? In this blog, I will walk you through the easiest ways to login when you lost the Key pair What is a key-pair file? Key-pair is a combination of a public and private key. Amazon EC2 uses public-key cryptography to encrypt and decrypt login information. Private key is only the way to get access to the instance, what if you lost the key? Is your servers lost in black hole? Thankfully nothing is lost you still can access your server, let me show you how can you solve this problem. Things that you should know before to proceed to this topic This procedure will requires s...

Start or Stop services in multiple Windows EC2 Instances using AWS Systems Manager

By
Use Case You are the admin over a large amount of EC2 instances and managing different AWS accounts under Organization and you have to start/stop/disable a service for all Windows EC2 Instances in the Organization. Rather than wasting labor hours to perform this activity in each instance manually, you want to automate the process using AWS Systems Manager. Recently Windows had a flaw in Print Spooler Remote Code Execution Vulnerability and Microsoft recommended to stop until the patch is applied, in order to apply this immediately, we can make use of this design Systems Manager Systems Manager (SSM) gives you visibility and control over your AWS infrastructure. Automation, a capability of AWS Systems Manager, simplifies common maintenance and deployment tasks of Amazon Elastic Compute Cloud (Amazon EC2) instances and other AWS resources. Automation helps you to do the following: Build automations to configure and manage instances and...

Automate Permission Boundary Attachment to IAM roles and Users

By
When we are managing multiple AWS Accounts in an Organization and each accounts will have their own requirement but as a centralized admin, we should be having a certain governance and compliance framework. IAM is a widely used AWS service and IAM roles/users are common used entity in AWS. As a centralized Admin, when we provide access to create IAM roles, cloud consumers in the landing zone accounts would create Users and Roles and attach Administrative policy and bypass the governance framework. In this blog, I will be briefing on restricting this scenario using IAM permission boundary and also deploying this setup through automation. AWS supports permissions boundaries for IAM entities (users or roles). A permissions boundary is an advanced feature for using a managed policy to set the maximum permissions that an identity-based policy can grant to an IAM entity. An entity's permissions boundary allows ...

Create Docker Environment locally and deploy a sample web application

By
Docker is a platform for developers and sysadmins to develop, deploy, and run applications with containers. You can refer Docker official website for more understanding about the docker. In this blog, I will walkthrough on how to setup a Docker Environment locally in your laptop, server or desktop. Installing Docker Desktop Previously, when we were working on a Windows or Mac Environment, setting up docker was a difficult task but Docker Desktop is designed to let you build, share and run containers as easily on Mac and Windows as you do on Linux. Docker handles the tedious and complex setup so you can focus on writing code. Pre-requisites for Docker Desktop Configure WSL 2 ( Recommended for Windows 10, 11 - All Editions) Hyper-V backend ( Recommended for Windows 10, 11 - Professional, Enterprise, Education Editions) We will use WSL 2 since i...

AWS Route 53 Inbound Resolver to resolve DNS for Multi Account Organization

By
Amazon Route53 Resolver The route 53 resolvers are contactable IP addresses (endpoints) where the DNS queries from different sources can be directed. There are two types of resolvers that administrators can deploy. Inbound Resolver As the name says inbound (DNS Resolutions coming in) which will enable your resources in the on-prem network to resolve AWS resource domain names or records in a Route 53 private hosted zone by allowing your on-prem network DNS resolvers to forward queries to Route 53 Resolver. Outbound Resolver As the name says Outbound (DNS Resolutions going out) which will enable your AWS resources to resolve the domain names of your on-prem network resources using resolver rules, which would forward selected queries to the on-prem network DNS resolvers On-prem to AWS DNS Resolution for ...
