Supported environment variables

This topic lists the supported environment variables that some SDKs and tools enable you to use in place of settings in the shared config and credentials files. For information about these files, see The shared config and credentials files.

Note

Not all SDKs and Tools that support a Config setting support the equivalent environment variable setting. See the details page for a Config setting for more information.

The listing for each variable links back to the Settings page for details about what that variable does.
