+# Installing Webmin and Docker on Ubuntu
+
+This guide walks you through installing Webmin on Ubuntu and expanding logical volumes via Webmin’s interface. Additionally, it covers Docker installation on Ubuntu.
+
+---
+
+## Part 1: Installing Webmin on Ubuntu
+
+Webmin is a web-based interface for managing Unix-like systems, making tasks such as user management, server configuration, and software installation easier.
+
+### Step 1: Update Your System
+
+Before installing Webmin, update your system to ensure all packages are up to date.
+
+```bash
+sudo apt update && sudo apt upgrade -y
+```
+
+### Step 2: Add the Webmin Repository and Key
+
+To add the Webmin repository, download and run the setup script.
+
+```bash
+curl -o setup-repos.sh https://raw.githubusercontent.com/webmin/webmin/master/setup-repos.sh
+sudo sh setup-repos.sh
+```
+
+### Step 3: Install Webmin
+
+With the repository set up, install Webmin:
+
+```bash
+sudo apt-get install webmin --install-recommends
+```
+
+### Step 4: Access Webmin
+
+Once installed, Webmin runs on port 10000. You can access it by opening a browser and navigating to:
+
+```
+https://<your-server-ip>:10000
+```
+
+If you are using a firewall, allow traffic on port 10000:
+
+```bash
+sudo ufw allow 10000
+```
+
+You can now log in to Webmin using your system's root credentials.
+

+
+## Part 2: Expanding a Logical Volume Using Webmin
+
+Expanding a logical volume through Webmin’s Logical Volume Management (LVM) interface is a simple process.
+
+### Step 1: Access Logical Volume Management
+
+Log in to Webmin and navigate to:
+
+**Hardware > Logical Volume Management**
+
+Here, you can manage physical volumes, volume groups, and logical volumes.
+
+### Step 2: Add a New Physical Volume
+
+If you've added a new disk or partition to your system, you need to allocate it to a volume group before expanding the logical volume. To do this:
+1. Locate your volume group in the Logical Volume Management module.
+2. Click **Add Physical Volume**.
+3. Select the new partition or RAID device and click **Add to volume group**. This action increases the available space in the group.
+
+### Step 3: Resize the Logical Volume
+
+To extend a logical volume:
+1. In the **Logical Volumes** section, locate the logical volume you wish to extend.
+2. Select **Resize**.
+3. Specify the additional space or use all available free space in the volume group.
+4. Click **Apply** to resize the logical volume.
+
+### Step 4: Resize the Filesystem
+
+After resizing the logical volume, expand the filesystem to match:
+1. Click on the logical volume to view its details.
+2. For supported filesystems like ext2, ext3, or ext4, click **Resize Filesystem**. The filesystem will automatically adjust to the new size of the logical volume.
+

+
+## Part 3: Installing Docker on Ubuntu
+
+This section covers installing Docker on Ubuntu.
+
+### Step 1: Remove Older Versions
+
+If you have previous versions of Docker installed, remove them:
+
+```bash
+sudo apt remove docker docker-engine docker.io containerd runc
+```
+
+### Step 2: Add Docker's Official GPG Key and Repository
+
+Add Docker’s GPG key and repository to your system’s Apt sources:
+
+```bash
+sudo apt-get update
+sudo apt-get install ca-certificates curl
+sudo install -m 0755 -d /etc/apt/keyrings
+sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
+sudo chmod a+r /etc/apt/keyrings/docker.asc
+
+echo \
+"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
+$(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
+sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
+
+sudo apt-get update
+```
+
+### Step 3: Install Docker
+
+Now, install Docker:
+
+```bash
+sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
+```
+
+### Step 4: Post-Installation Steps
+
+To allow your user to run Docker commands without `sudo`, add your user to the Docker group:
+
+```bash
+sudo usermod -aG docker $USER
+newgrp docker
+```
+
+Test your Docker installation by running the following command:
+
+```bash
+docker run hello-world
+```
