Amazon Web Services named profile per project

You're a freelance software developer. You have two directories to distinguish between your personal and client projects:

• ~/code for personal projects.
• ~/client-foo for client foo's projects.

You use Amazon Web Services for both personal and client projects, and you have AWS named profiles set up for each account you interact with:

• The personal profile for your personal AWS account.
• The foo profile for client foo's AWS account.

Right now, you need to remember to run aws with --profile personal or --profile foo depending on the project you're working on.

However, wev's contextual environment variables can manage that for you.

1. Install wev:

   pip3 install wev
   

2. Create ~/code/wev.yml:

   AWS_DEFAULT_PROFILE:
     plugin:
       id: wev-echo
       value: personal
   

3. Create ~/client-foo/wev.yml:

   AWS_DEFAULT_PROFILE:
     plugin:
       id: wev-echo
       value: foo
   

4. Open a terminal and cd into ~/code. Verify that the personal named profile is used:

   cd ~/code
   wev aws sts get-caller-identity
   

   {
     "UserId": "000000000000",
     "Account": "000000000000",
     "Arn": "arn:aws:iam::000000000000:user/you"
   }
   

5. Open a terminal and cd into ~/client-foo. Verify that the foo named profile is used:

   cd ~/client-foo
   wev aws sts get-caller-identity
   

   {
     "UserId": "111111111111",
     "Account": "111111111111",
     "Arn": "arn:aws:iam::111111111111:user/contractor"
   }
