Delete Docker Desktop

How to delete Docker Desktop from a Windows machine and remove "host.docker.internal":

Docker's uninstall process may not always remove entries like host.docker.internal. If you uninstall Docker and still have host.docker.internal entries in your hosts file, it can cause DNS resolution issues for your container. To delete Docker Desktop from a Windows machine and remove "host.docker.internal" resolution issues, you need to uninstall Docker Desktop, then manually edit the hosts file to remove Docker's entries. Additionally, you may need to refresh the DHCP configuration to ensure the changes are reflected.

Here's a step-by-step guide:

1. Uninstall Docker Desktop:

• Open Docker Desktop.
• Click the Troubleshoot icon in the top-right corner.
• Select "Uninstall".

Alternatively, you can uninstall Docker for Windows through the Windows Settings > Apps & Features.

2. Edit the hosts file:

• Open the hosts file located at C:\Windows\System32\Drivers\etc\hosts.

Remove any lines that start with 192.168.1.4 or 127.0.0.1 followed by host.docker.internal.

• Save the file.

3. Refresh DHCP (Optional):

• If you're still experiencing issues resolving host.docker.internal after editing the hosts file, you can try refreshing the DHCP configuration.
• Open a command prompt and run ipconfig /flushdns.

4. Restart your machine.

Explanation:

• host.docker.internal: This DNS name is used by Docker containers to refer to the host machine. It's automatically added to the hosts file when Docker Desktop is installed.

Why remove it?

Docker's uninstall process may not always remove entries like host.docker.internal. If you uninstall Docker and still have host.docker.internal entries in your hosts file, it can cause DNS resolution issues for your container.

5. Refreshing DHCP:

This process helps ensure that your system's DNS cache is updated with the changes you've made to the hosts file.
