⁠Configuring Your Workstation for Prowler App

If your workstation's architecture is incompatible, you can resolve this by:

• Setting the environment variable: DOCKER_DEFAULT_PLATFORM=linux/amd64
• Using the following flag in your Docker command: --platform linux/amd64

⁠Common Issues with Docker Pull Installation

If you want to use AWS role assumption (e.g., with the "Connect assuming IAM Role" option), you may need to mount your local .aws directory into the container as a volume (e.g., - "${HOME}/.aws:/home/prowler/.aws:ro"). There are several ways to configure credentials for Docker containers. See the Troubleshooting⁠ section for more details and examples.

You can find more information in the Troubleshooting⁠ section.
