-# UTORRENT
+# Deploy K3S on Alpine
+
+## Step 1: Install Alpine from ISO
+
+- Download the standard or virtual x86_64 ISO file.
+- Write the ISO to a USB flash drive (using a tool like Rufus) or mount it to a virtual machine (VMware, QEMU, or VirtualBox).
+- Boot your machine from the ISO (make sure Secure Boot is disabled in your BIOS if needed).
+- At the login prompt, log in as root with no password.
+
+## Step 2: Run the Setup Script
+
+- Type the following command to start the interactive installer:
+
+  **bash**
+  ```
+  setup-alpine
+  ```
+Use code with caution.
+- Follow the prompts to configure your system:
+	- Keymap & Variant: Select your keyboard layout (e.g., us).
+	- Hostname: Enter a name for your machine (e.g., alpine-host).
+	- Network: Choose your network interface (e.g., eth0) and select DHCP or configure a static IP.
+	- Root Password: Enter and confirm a strong password for the root user.
+	- Timezone: Select your local timezone (e.g., Asia/Singapore or UTC).
+	- Proxy / NTP: Choose your HTTP proxy (usually none) and NTP client (e.g., chrony or busybox).
+	- APK Mirror: Type f to automatically detect and select the fastest package mirror.
+	- SSH Server: Choose your preferred SSH server (e.g., openssh).
+	- Disk Installation: Select your target storage drive (e.g., sda or vda) and choose sys for a traditional full disk installation (or data/lvm if you have specific needs).
+	- Confirm the prompt to erase the disk and write the system.
+
+- For cloned VM
+    - Change hostname
+      ```
+      $ vi /etc/hostname 
+      $ vi /etc/hhosts 
+      $ hostname -F /etc/hostname
+      ```
+    - Change ip address
+      ```
+      $ vi /etc/network/interface  
+      $ /etc/init.d/networking restart 
+      ```
+    - Renew ssh host keys
+      ```
+      $ cd /etc/ssh 
+      $ rm ssh_host_* 
+      $ ssh-keygen -A 
+      ```
+
+## Step 3: Install Chrony
+  ```
+  $ apk add chrony
+  $ vi /etc/chrony/chrony.conf 
+    #pool pool.ntp.org iburst
+    server 192.168.122.1 iburst
+  $ /etc/init.d/chronyd start|restart  
+  ```
+
+  **verify**
+  ```
+  chronyc sources -v
+  chronyc tracking
+  ```
+  
+## Step 4: Install k3S 
+
+**update-extlinux**
+```
+$ apk add --no-cache curl
+$ echo "cgroup2 /sys/fs/cgroup cgroup2 rw,nosuid,nodev,noexec,relatime,nsdelegate 0 0" >> /etc/fstab

+$ cat > /etc/cgconfig.conf <<EOF
+mount {

+$ update-extlinux
+$ reboot
