Installing Portainer

Portainer is an open-source management tool that allows users to easily manage their Docker environments. It provides a simple and intuitive web-based user interface for managing Docker containers, images, networks, and volumes, as well as the ability to deploy and manage stacks. Portainer also has built-in support for managing multiple Docker environments, making it a useful tool for both development and production environments.
Copy again the code below to install Portainer.
