+Here's a concise guide to set up a minimal Alpine Linux system with the specified packages and configurations:
+
+1. Install Alpine Linux:
+   - Download the Alpine Linux ISO from the official website.
+   - Create a bootable USB drive or use a virtual machine.
+   - Boot from the installation media and follow the installation wizard.
+
+2. Update the system and add the community repository:
+   ```
+   apk update
+   apk add vim
+   vi /etc/apk/repositories
+   ```
+   Uncomment the line for the community repository, then save and exit.
+
+3. Install the required packages:
+   ```
+   apk add qemu-guest-agent htop docker curl wget iperf3 sudo
+   ```
+
+4. Create a system user and add them to the docker group and sudoers:
+   ```
+   adduser -s /bin/ash myuser
+   addgroup myuser docker
+   visudo
+   ```
+   Add the following line to the sudoers file:
+   ```
+   myuser ALL=(ALL) ALL
+   ```
+   Save and exit.
+
+5. Start and enable the Docker service:
+   ```
+   rc-update add docker default
+   service docker start
+   ```
+
+6. Install and configure SSH:
+   ```
+   apk add openssh
+   rc-update add sshd
+   service sshd start
+   vi /etc/ssh/sshd_config
+   ```
+   Uncomment and modify the following lines:
+   ```
+   PermitRootLogin no
+   PasswordAuthentication yes
+   ```
+   Save and exit.
+
+7. Restart the SSH service:
+   ```
+   service sshd restart
+   ```
+
+8. Log in as the newly created user:
+   ```
+   su - myuser
+   ```
+
+9. Test Docker functionality:
+   ```
+   docker run hello-world
+   ```
+
+10. Test sudo privileges:
+    ```
+    sudo apk update
+    ```
+
+11. Connect to the system via SSH:
+    ```
+    ssh myuser@<server-ip>
+    ```
+
+Additional notes:
+- Make sure to set a strong password for the user account.
+- Consider using SSH key-based authentication for enhanced security.
+- Regularly update the system and installed packages using `apk update` and `apk upgrade`.
+- Configure the system as per your specific requirements and security best practices.
+
+This guide provides a basic setup for a minimal Alpine Linux system with the requested packages and configurations. Feel free to customize it further based on your needs.
