2. Recreate Logical Architectual Diagram in Lucid Charts

3. Create an Admin User

While creating the admin user, I created a User Group with the AdministratorAccess permission and added the user to it. With the user group I can easily manage all users with administrative permission. I added MFA to the admin user for extra security layer to the user. Conceptual Diagram Preview

4. Use CloudShell

The AWS CloudShell is a web based and pre-authenticated shell for utilizing AWS resources via the command line. I ran commands on the Cloudshell to examine their output. Some these commands are:

  • aws
  • aws help
  • aws sts get-caller-identity
  • aws account get-contact-information

5. Generate AWS Credentials

I created access key and secret for my admin user to provide programmatic access to my aws resources. Then I configured my aws credentials using to methods

  1. used aws configure

AWS configure Credentials

  1. set env var using export

Set AWS credentials in ENV

6. Installed AWS CLI

I installed AWS CLI manually on my gitpod after which I added the installation script to my gitpod config file to automatically install it every time I start a new gitpod instance.

Here is the installation command for Linus machines

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install

I updated my gitpod.yml file with the script below to automate the installation

tasks:
  - name: aws-cli
    env:
      AWS_CLI_AUTO_PROMPT: on-partial
    init: |
      cd /workspace
      curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
      unzip awscliv2.zip
      sudo ./aws/install
      cd $THEIA_WORKSPACE_ROOT
