AWS Region Now Exported by atmos auth env

The atmos auth env command now exports AWS_REGION and AWS_DEFAULT_REGION when region is configured in your identity settings.

What Changed​

The atmos auth env command exports AWS credentials to your shell for use with external tools (AWS CLI, direct terraform runs, etc.). Previously it only exported credential file paths:

  • AWS_SHARED_CREDENTIALS_FILE
  • AWS_CONFIG_FILE
  • AWS_PROFILE

Now it also exports region when configured:

  • AWS_REGION
  • AWS_DEFAULT_REGION

When You Need This​

Use atmos auth env when you want to run external tools that need AWS credentials exported to the shell:

# Export auth environment for external tools
eval $(atmos auth env --identity my-identity)

# Now external tools have access to AWS credentials and region
aws s3 ls
terraform plan  # running terraform directly, not via atmos

When You Don't Need This​

For atmos commands (atmos terraform plan, atmos terraform apply, etc.), region is automatically injected - no sourcing required. The !env AWS_REGION YAML function works automatically in stack configurations when using atmos commands.

Important Notes​

  • Region is only exported when explicitly configured in your identity or provider
  • No default region is assumed - if you don't configure region, it won't be exported
  • This is purely additive and doesn't break existing scripts
