This will make Terraform lookup AWS credentials from the `~/.aws/credentials` file using the workspace name as the stanza name. For example the credentials file would look like the shared-creds file in this repo.
This will make Terraform lookup AWS credentials from the `~/.aws/credentials` file using the workspace name as the stanza name. For example the credentials file would look like the shared-creds file in this repo.
## atmos -t
Adding the `-t` flag to atmos will make it generate a new `~/.aws/credentials` file from environment variables. You must first include the `default` access key ID & secret access key like this:
```
DEFAULT_ACCESS_KEY_ID=id
DEFAULT_SECRET_ACCESS_KEY=key
```
All additional workspaces need to be prefixed in the same way:
```
DEV_ACCESS_KEY_ID=id
DEV_SECRET_ACCESS_KEY=key
QA_ACCESS_KEY_ID=id
QA_SECRET_ACCESS_KEY=key
```
Note: Atmos will override your default credentials file as this functionality is for use in a docker container or in situations where you would rather use variables.
