Allow configuring a different parent directory for .aws

[krystalcode]

Describe the feature

Allow configuring a different parent folder/location for the .aws folder that holds the config/credentials files. Currently, the AWS_CONFIG_FILE can configure a location for the config file. Other than that, in many places in the code the .aws is assumed to be under the $HOME folder.

Use Case

Some applications may trigger actions either via CLI or via the UI. These are commonly configured as separate users, that may not even have a home directory. In such cases, the .aws folder that holds the config/credentials files needs to be placed in a location that both users have access to.

Proposed Solution

Introduce a new environment variable AWS_HOME that will define the location of the parent folder for .aws.

Hi @krystalcode, I think this is already possible. You just need to set the env variable HOME to the location you want, as we can see here.

Please let me know if that helps!

Thanks!

Hi @yenfryherrerafeliz , thanks for the response. The reason that I did not use that is that HOME is a generic Linux environment variable that should not be changed because it has a specific meaning in Linux and other processes within or outside of the application might rely upon. The HOME always needs to be the actual linux home directory of the user and should never be changed.

In the case that I mention in the description, the PHP/application user has a different home directory, while the web server user e.g. www-data would have a different home directory, or even no home directory at all. Home directories should never be changed.

Hi @krystalcode, after investigating more on this feature request, at this time we cannot support another env variable that replaces the HOME one. Why?, we do offer other options to set the config and the credentials file paths. Those environment variables are ENV_CONFIG_FILE to set the config file path and AWS_SHARED_CREDENTIALS_FILE to set the credentials file path.

I hope those options helps you. In any case, please feel free to reach out if is there anything else that we are able to help with.

Thank you!
