DevOps(Day-52) : AWS and IAM Basics

 

  • AWS

    • User Data in AWS

  • IAM

  • Task 1: Configure user data in AWS

Amazon Web Services is one of the most popular Cloud Providers that have a free tier too for students and Cloud enthusiasts for their Hands-on while learning (Create your free account today to explore more on it.

  • When you launch an instance in Amazon EC2, you have the option of passing user data to the instance that can be used to perform common automated configuration tasks and even run scripts after the instance starts. You can pass two types of user data to Amazon EC2: shell scripts and cloud-init directives.

  • You can also pass this data into the launch instance wizard as plain text, as a file (this is useful for launching instances using the command line tools), or as base64-encoded text (for API calls).

  • This will save time and manual effort every time you launch an instance and want to install any application on it like Apache, docker, Jenkins etc

AWS Identity and Access Management (IAM) is a web service that helps you securely control access to AWS resources. With IAM, you can centrally manage permissions that control which AWS resources users can access. You use IAM to control who is authenticated (signed in) and authorized (has permissions) to use resources.

Aim: - Launch EC2 instance with already installed Jenkins on it. Once the server shows up in the console, hit the IP address in the browser and your Jenkins page should be visible.

  1. Navigate to AWS console and launch a new instance.

  2. Provide the suitable key pairs and security groups.

  3. Select the advanced settings in the instance creation page.

  4. Navigate to User-data section and write a shell script to install Jeknins on the server.

  5. Include the port 8080 which is the Jenkins default port in the security group of the server.

  6. Start the EC2 instance and using the public IP access the URL through port 8080.

  7. YOu can see Jenkins would be running now.

Thanks for reading my article. Have a nice day.

We are automating the whole team's work from the code-building stage to code deployment. Scenario 1:- In a company, there is a project in which developers are writing the code and deploying it to the QA environment frequently for each sprint. This code is then tested by the testing team. Suppose there is a situation of mishap happens where the testing team used the older code

File Management in Linux TABLE OF CONTENTS In Linux, most of the operations are performed on files. And to handle these files Linux has directories also known as folders which are maintained in a tree-like structure. Though, these directories are also a type of file themselves. Linux has 3 types of files: Regular Files :  It is the common file type in Linux. it includes files like – text files, images, binary files, etc. Such files can be created using the touch command. They consist of the majority of files in the Linux/UNIX system. The regular file contains ASCII or Human Readable text, executable program binaries, program data and much more. Directories :  Windows call these directories as folders. These are the files that store the list of file names and the related information. The root directory(/) is the base of the system, /home/ is the default location for user’s home directories, /bin for Essential User Binaries, /boot – Static Boot Files, etc. We could create new directories
