This code installs Docker on a Windows system, handling the installation process and configuring necessary firewall and network settings using elevated privileges.

Run example

npm run import -- "How do I fix the firewall for Docker"

This code snippet installs Docker on a Windows system using the elevate tool to run commands with elevated privileges.

Here's a breakdown:

1. Setup:

   • It defines paths to the downloaded Docker installer (dockerLoc) and the elevate.exe executable.
   • It constructs PowerShell commands to configure the Windows firewall and network settings for Docker.

2. Docker Installation:

   • It uses elevate.exe to run the Docker installer (msiexec) with silent installation options (/qn) and logs output to a file (/L*V!).
   • It handles the installation output and errors using event listeners.

3. Post-Installation Configuration:

   • After installation, it uses elevate.exe again to execute PowerShell commands:
     • Creates a firewall rule to allow inbound traffic on port 2375 for Docker.
     • Configures the network interface for Docker to use a private network.

4. Completion:

   • Once both installation and configuration are complete, it signals the completion of the process to the asynchronous context ($.done('installed Docker')).
