Vagrant Web Console version

This project provides a web console for managing Vagrant VMs. The console allows you to start, stop, reload, reboot, and remove VMs, as well as view the current status of all VMs.

Build for run

1. Build the vvmanager executable:

   go build -o vvmanager main.go

Usage

The webconsole.sh script is used to manage the web console server. It supports start, stop, restart, and run commands.

• start: Starts the web console server in the background and rotates logs daily.
• stop: Stops the running web console server.
• restart: Restarts the web console server.
• run: Runs the web console server in the foreground.

To use the script, run the following commands:

1. Make the script executable:

   chmod +x webconsole.sh

2. Start the web console server:

   ./webconsole.sh start

3. Stop the web console server:

   ./webconsole.sh stop

4. Restart the web console server:

   ./webconsole.sh restart

5. Run the web console server in the foreground:

   ./webconsole.sh run

Configuration

The webconsole.sh script handles log rotation and maintains a PID file to manage the server process. Logs are rotated daily, with a maximum of 4 log files retained (history.log, history.log.1, history.log.2, and history.log.3).

Example

Here is an example session using the webconsole.sh script:

1. Start the server:

   ./webconsole.sh start

2. Access the web console by navigating to http://<your_server_ip>:8080 in your web browser.

3. Stop the server:

   ./webconsole.sh stop

4. Restart the server:

   ./webconsole.sh restart

Troubleshooting

• Ensure all dependencies are installed and properly configured.
• Check the log files (history.log) for any errors or warnings.
• If the server does not start, verify that no other process is using port 8080.
