-# 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 {
+  cpuacct = /cgroup/cpuacct;
+  memory = /cgroup/memory;
+  devices = /cgroup/devices;
+  freezer = /cgroup/freezer;
+  net_cls = /cgroup/net_cls;
+  blkio = /cgroup/blkio;
+  cpuset = /cgroup/cpuset;
+  cpu = /cgroup/cpu;
+}
+EOF
+
+$ sed -i 's/default_kernel_opts="pax_nouderef quiet rootfstype=ext4"/default_kernel_opts="pax_nouderef quiet rootfstype=ext4 cgroup_enable=cpuset cgroup_memory=1 cgroup_enable=memory"/g' /etc/update-extlinux.conf
+
+$ update-extlinux
+$ reboot
+```
+
+**cni-plugins**
+```
+$ apk add --no-cache cni-plugins --repository=http://dl-cdn.alpinelinux.org/alpine/edge/community
+$ export PATH=$PATH:/usr/share/cni-plugins/bin
+$ echo -e '#!/bin/sh\nexport PATH=$PATH:/usr/share/cni-plugins/bin' > /etc/profile.d/cni.sh
+$ apk add iptables
+```
+
+**install k3s**
+```
+$ curl -sfL https://get.k3s.io | sh -
+```
