How to install and use VNC on Alpine Linux?

To install and use VNC on Alpine Linux, follow these steps:

Update the Package List:
First, ensure your package list is up to date by running:
```
apk update
```
Install VNC Server:
Install a VNC server such as tigervnc or x11vnc. For this example, we'll use tigervnc:
```
apk add tigervnc
```
Set Up VNC Password:
Set a password for your VNC session. This command will prompt you to enter and confirm a password:
```
vncpasswd
```
Create a VNC Startup Script:
Create a script to start your VNC server with the desired display number and resolution. For example, create a file named ~/.vnc/xstartup with the following content:
```
#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
gnome-session &
```
Make the script executable:
```
chmod +x ~/.vnc/xstartup
```
Start VNC Server:
Start the VNC server with the display number (e.g., :1):
```
vncserver :1 -geometry 1280x800 -depth 24
```
Connect to VNC Server:
Use a VNC client to connect to your Alpine Linux machine. The connection details will be hostname:display_number (e.g., 192.168.1.100:1).
