C0 - Part IV - AWS CLI

This page describes the AWS CLI Challenge

Prerequisites

• Get the credentials (see your dev-ops teams channel in teams).

• Download and install the AWS CLI

Step 01 - Initial setup

Once the CLI is installed, we need to set up the profile we want to use with the CLI.

Solution for a single profile:

aws configure
AWS Access Key ID [********************]:
AWS Secret Access Key [********************]:
Default region name [None]:
Default output format [json]:

Solution for a multiple profiles:

Open the file "credentials" from there C:\Users\[yourUserName]\.aws and add a new profile like this:

//add this kind of bloc at the end of credentials
[ProfileName] //do not need to be the same as the iam user
aws_access_key_id = ****
aws_secret_access_key = ****

Then, do not forget to add the argument --profile to your CLI command.

Step 02 - Get the list of instances

[Request]
//with default profile
aws ec2 describe-instances

//with specific profile
aws ec2 describe-instances --profile CLDGRP99 --region eu-south-1

[Response]
{
    "Reservations": [
        {
            "Groups": [],
            "Instances": [
                {
                    "AmiLaunchIndex": 0,
                    "ImageId": "ami-074b35d22662678b3",
                    [...]

Step 03 - Start A list of instances
