Guide for setting up AWS CLI on OS X

Snowpal AWS CLI Instructions: This article was written a while back but should still serve as a useful (first) reference.

1. Create a User on AWS Console

This step requires admin level access for the AWS account.

• Log in to the AWS console as an admin

• Go to IAM

• Create a User Group with relevant permissions and give it a meaningful name

• Create a User with programmatic access and copy the Access Id and secret 

• Assign the user into the group created above

• Share the Access key and secret with the CLI user

For updated documentation and best practices of this process, please visit this guide by AWS.

2. Install and Setup AWS CLI

• For installing AWS CLI v2 from terminal, type in the following command,

curl "https://awscli.amazonaws.com/AWSCLIV2.pkg" -o "AWSCLIV2.pkg"

sudo installer -pkg AWSCLIV2.pkg -target /

Note: The command above will install v2 of the AWS CLI which is currently the latest version. In future if the version upgrades, visit this link for an updated command or a GUI installer.

• For configuring a CLI user, open command line and run the following command

aws configure --profile snowpal-dev 

• Enter the provided access key

• Enter the provided credentials, 

• Enter region as us-east-2,

• Just hit enter on default output

Fill in with the provided information

If everything is successful then you are now ready to use AWS CLI.

For more information on where the credentials are stored on your machine, you can visit https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-quickstart.html

3. Installing AWS SAM CLI

For installing SAM CLI via homebrew, the first step is to install homebrew. If you already have homebrew installed, then you can skip this step.

Run this command to see if you already have homebrew,

brew --version

To install homebrew on your machine, run the following command,

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

Make sure to follow the prompts and once homebrew is installed, you will see a similar output,

 Homebrew 2.5.7

 Homebrew/homebrew-core (git revision 1be3ad; last commit 2020-10-29)

 Homebrew/homebrew-cask (git revision a0cf3; last commit 2020-10-29)

To install SAM CLI via homebrew, run the following commands,

brew tap aws/tap

brew install aws-sam-cli

This will install SAM CLI on your machine, to verify the installation, simply run,

sam --version

You are now ready to go ahead and start creating SAM applications.
