 AWS Systems Manager eases the operations and maintenance of automation(s) of common administrative and security tasks from one single window which is AWS Systems Manger Console via 'Run Command'. We can perform lot of tasks like applying IAM role to EC2 instances, Attach EBS Volumes, Run Ansible Playbooks at target nodes without having to have access to keys of those instances

Now, AWS has come up with yet another feature which was most awaited, i.e., to run Chef Recipes in AWS Instances irrespective Windows or Linux OS

HowTo Upgrade to AWSCLI Version 2

While launching instance in EC2, instances come with default AWSCLI verison 1.xx.xx installed. If we have to use the latest features in line with what AWS releases across services, aspected with AWSCLI, we will have to upgrade the CLI version to 2.x

Let us see how to do this in EC2 instances

Pre-requisites:

• AWS Login access & credentials
• Permissions and/or Access policies to upgrade utilities/tools in EC2

 

 Getting Started:

• Log in to the AWS Console
• Launch an EC2 under free-tier or log in/ssh into your EC2 via putty or other modes of connection allowed to you
• run 'sudo yum update -y', if required
• check the currently available awscli version

 

• download and unzip the awscli bundle from aws location

 

• run sudo install
