You can solve this by bind-mounting your credentials file into the container:

docker run -v $HOME/.aws:/root/.aws ...

I don't like doing this, because it means that something inside the container can change files in your directory in ways that you might not expect (and making them owned by root).

I prefer instead using environment variables to hold my credentials, and passing them to Docker using -e:

docker run -e AWS_ACCESS_KEY_ID -e AWS_SECRET_ACCESS_KEY -e AWS_DEFAULT_REGION -e AWS_REGION ...

Note that these variables must already be defined in your environment to be passed as -e VARNAME (and you shouldn't use -e VARNAME=VALUE because that makes the keys visible with ps).
