Day-5 | AWS CLI Full Guide | How to connect to EC2 Instance from UI & Terminal | AWS CFT walk though

Introduction and Overview

In this section, Abhishek introduces the topic of creating virtual machines efficiently and highlights the importance of automation in the process.

Understanding Efficient Virtual Machine Creation

• Abhishek recommends watching previous videos from Day Zero to Day Four to grasp foundational concepts before proceeding with today's lesson.

• Automation plays a crucial role in enhancing efficiency when creating virtual machines. Various tools like AWS API, AWS CDK, AWS CLI, AWS CloudFormation templates, and Terraform can be utilized for automation.

• The first step is learning how to log into an AWS EC2 instance. Abhishek demonstrates accessing the instance through the AWS console and establishing a connection.

Logging into AWS EC2 Instance

This part focuses on logging into an AWS EC2 instance using different methods for efficient management.

Accessing Through AWS Console

• To log in via the AWS console, navigate to the EC2 dashboard, select the running instance, click on the instance ID, and choose "Connect" to establish a connection.

• Once connected, users can interact with the virtual machine remotely by executing commands like creating files using terminal instructions.

Connecting Through Terminal

• Logging in through terminals is recommended for efficiency over using the UI. Abhishek suggests installing a terminal on your personal laptop for easier access.

• For Mac users, Abhishek recommends iTerm as a preferred terminal option. Windows users can opt for tools like PuTTY or MobileXterm for seamless connectivity.

Terminal Options for Remote Access

Exploring various terminal options suitable for remote access to virtual machines based on different operating systems.

Terminal Choices Based on OS

• Windows users have multiple options such as PuTTY and MobileXterm for connecting to virtual machines efficiently.

Connecting to AWS Virtual Machine via Terminal

In this section, the speaker demonstrates how to connect to an AWS virtual machine using a terminal.

Connecting to AWS Virtual Machine

• The public IP address is crucial for connecting externally.

• SSH authentication requires a key-value pair for security.

• Permissions on the .pem file should be restricted (chmod 600) for security.

• Successful login demonstrated through CLI connection.

Creating Files and Connecting via CLI

This part focuses on creating files and connecting to the server through the Command Line Interface (CLI).

Creating Files and CLI Connection

• Demonstrates creating a file in the AWS instance through CLI.

• Recap of learning about virtual machines and automation options using scripts/API.

Terminating Instances and Best Practices

The speaker discusses terminating instances and best practices for managing AWS resources.

Terminating Instances

• Importance of stopping instances before termination for billing purposes.

Creating AWS Resources Using AWS CLI

In this section, the speaker discusses the process of creating AWS resources using AWS CLI, emphasizing the ease and efficiency it offers for automating tasks.

Introduction to AWS CLI

• AWS CLI is a command line interface that allows direct interaction with AWS APIs to create resources.

• To begin, download and install AWS CLI based on your operating system (Windows, Mac OS, Linux).

Authentication and Configuration

• After installation, authenticate by creating access keys in the AWS console under security credentials.

• Securely store access key information and configure AWS CLI using AWS configure command with access key ID, secret access key, region, and output format.

Interacting with AWS Services

• Once authenticated, commands entered in the CLI reflect actions in AWS; explore services like S3 buckets using commands such as AWS S3 LS.

• Verify created resources by comparing information retrieved from commands with what is displayed in the UI.

AWS Automation with CLI and CloudFormation

In this section, the speaker discusses automating tasks using AWS CLI and CloudFormation templates.

Automating with AWS CLI

• AWS CLI allows for automation of tasks in AWS.

• Commands like AWS CLI ec2 instance create can be used to create an EC2 instance.

• Security credentials need to be created and authenticated to interact with AWS using CLI commands.

• Commands can be stored in scripts or GitHub repositories for easy access and reuse.

Working with CloudFormation Templates

• CloudFormation templates are another way to interact with AWS API for resource creation.

• Examples of CloudFormation templates can be found in repositories like AWS Labs on GitHub.

• Templates can be uploaded from local files or S3 buckets for creating stacks in CloudFormation.

Automating Tasks with Python and Boto3

This part covers automating tasks using Python scripts and the boto3 module.

Using Boto3 Module

• Boto3 is a well-maintained Python module for interacting with AWS services via APIs.

• Configuration through AWS configure allows boto3 to access necessary information.

Conclusion

The conclusion emphasizes understanding resource creation through UI, CLI, and CloudFormation, preparing for future learning on infrastructure as code concepts.

Documentation and Automation on AWS

In this section, the speaker discusses the importance of documentation in learning how to automate tasks on AWS and Microsoft Azure.

Learning Automation Processes

• Documentation is crucial for understanding commands, requests, responses, and handling automation tasks.

• The process of automating tasks on AWS is applicable to Microsoft Azure as well.

Using AWS CLI and Boto3 Module

This part focuses on utilizing the AWS Command Line Interface (CLI) and the Boto3 module for automation.

Utilizing AWS CLI

• Accessing security credentials in your account is essential before using AWS CLI or Boto3.

• Downloading the AWS CLI package from documentation is necessary for running commands.

Configuring AWS CLI

Configuring the AWS CLI is a critical step in enabling interaction with AWS services through the command line.

Configuration Process

• Running AWS configure prompts for essential information like access key ID and secret key.

• After providing necessary information, users can effectively interact with AWS services via CLI for automation purposes.

Practical Application and Assignment

Practical application of learned concepts and an assignment related to installing the AWS CLI package are discussed here.

Hands-On Practice

• Encouragement to install the AWS CLI package, create security credentials, and authenticate with terminal access.

• Assigning tasks such as creating S3 buckets or listing EC2 instances using provided documentation guidelines.

Exploring Documentation for Commands

Exploring the extensive documentation available for various commands within the AWS ecosystem.

Navigating Documentation

• Guidance on accessing detailed examples and references in the official AWS CLI documentation.

• Demonstrating how to search for specific commands like creating EC2 instances within the documentation.
