This section guides you through configuring Docker Scout for optimal performance.

Before configuring Docker Scout, ensure you have the following:

1. Docker Scout Installed: Make sure Docker Scout is already installed on your system.
2. Docker Engine Running: Docker Scout requires the Docker Engine to be running. Verify by executing:

   docker-scout --version

1. Locate the configuration file:

   C:\Users\<YourUsername>\Docker\scout\config.yaml:

2. Edit the file to include:

   enableTelemetry: true
   updateFrequency: daily
   scanOnBuild: true

3. Set the environment variable in PowerShell:

   $env:DOCKER_SCOUT_API_KEY = "YOUR_API_KEY_HERE"
   

1. Open the configuration file:

   ~/Library/Application Support/Docker/scout/config.yaml
   

2. Add the following settings:

   updateFrequency: daily
   scanOnBuild: true
   apiKey: YOUR_API_KEY_HERE
   

3. Set environment variables in your shell profile (~/.zshrc or ~/.bash_profile):

   export DOCKER_SCOUT_API_KEY="YOUR_API_KEY_HERE"

1. Open the configuration file:

   ~/.docker/scout/config.yaml
   

2. Update the config file located at ~/.docker/scout/config.yaml:

   enableTelemetry: true
   updateFrequency: daily
   scanOnBuild: true
   apiKey: YOUR_API_KEY_HERE

3. Add environment variables in .bashrc or .zshrc:

   export DOCKER_SCOUT_API_KEY="YOUR_API_KEY_HERE"

Create a Dockerfile to set up the environment and install Docker Scout:

FROM python:3.10-slim
ENV DEBIAN_FRONTEND=noninteractive
RUN apt-get update && apt-get install -y wget
RUN pip install docker-scout
COPY config.yaml /etc/docker/scout/config.yaml

Run the following command in the terminal to build the Docker image:

docker build -t docker-scout-image .

To run the Docker container, use the following command:

docker run -d --name docker-scout-container docker-scout-image

1. Check Docker Scout Version:

   docker-scout --version

   This command displays the currently installed version of Docker Scout.

   Example output:

   Docker Scout version 1.2.3

2. Scan All Docker Images:

   docker-scout scan --all

   The docker-scout scan --all command scans all available Docker images for security vulnerabilities and optimization opportunities.

   Example Output:

   Scanning all local images...
   
   Image: ubuntu:22.04
   Critical vulnerabilities: 1
   High vulnerabilities: 2
   Medium vulnerabilities: 5
   
   Optimization suggestions:
   - Remove unused dependencies
   - Minimize layers in the Dockerfile

3. View Docker Scout Logs:

   docker-scout logs

   This command displays logs from the Docker Scout container, useful for debugging or checking the status of recent scans.

   Example log Output:

   2024-11-21 12:30:00 [INFO] Starting scan for image: ubuntu:22.04
   2024-11-21 12:30:10 [WARN] Critical vulnerability detected in library: openssl
   2024-11-21 12:30:20 [INFO] Scan completed successfully.

   Advanced Outputs:

   • Scan a Specific Image:

   docker-scout scan --image <image-name>

   Example Output:

   docker-scout scan --image nginx:latest
   
   Scanning image: nginx:latest
   Critical vulnerabilities: 0
   High vulnerabilities: 1
   Medium vulnerabilities: 3

   • Export Results in JSON Format:

   docker-scout scan --all --json

   Example Output:

   docker-scout scan --all --json > results.json
   Results exported to: results.json

   • Exclude Specific Vulnerabilities:

   docker-scout scan --exclude <vulnerability-ID>

If Docker Scout provides a web interface, you can access it via your web browser at http://localhost:5000 or the port you have configured.

This section covers common issues users may encounter while using Docker Scout and provides actionable solutions to resolve them effectively.

• Cause: Docker Scout might be unable to find the image, or the image has not been pulled.

• Solution: Check if the image exists using:

  docker images

  This command lists all locally available Docker images. If the image is not present, pull it:

  docker pull <image-name>

  Replace <image-name> with the correct image name to download it from the registry, then verify the image availability using the following command:

  docker images

• Cause: Vulnerabilities may be flagged for packages that are not actively used.

• Solution: Confirm if a package is in use by executing:

   docker run --rm <image-name> dpkg -l | grep <package>

  If the package is outdated, update the base image with:

  docker pull <base-image>

• Cause: Analysis may be delayed due to large image sizes or network latency.
• Solution: Streamline Dockerfile commands to minimize image size and ensure a stable network connection.

• Cause: The Docker Scout CLI extension might not be installed.

• Solution: Check the installation status with:

   sudo usermod -aG docker $USER

• Cause: The user does not have sufficient permissions to execute Docker Scout commands.

• Solution: Add the user to the Docker group with the following command:

   sudo usermod -aG docker $USER

Afterward, restart the terminal for the changes to take effect.

• Cause: Docker Scout's vulnerability database might be outdated or incomplete.

• Solution: Update Docker Scout using:

   docker extension update docker/scout

  Verify the update by running:

  docker-scout --version

  Re-run the scan to ensure the issues are detected:

  docker-scout scan --all
