nunesfd/hostcontrol repository overview

⁠HostControl

https://github.com/nunesfd/hostcontrol⁠

HostControl is a terminal-based desktop application developed with Python and the Textual⁠ library.

This tool is specifically designed to manage the /etc/hosts file, providing an intuitive interface that allows users to add, edit, and remove groups of hosts easily and efficiently.

⁠Features

• Manage groups of hosts (add, edit, remove)
• View the synchronization status of each group
• User-friendly terminal-based interface
• Keyboard shortcuts for quick actions

⁠IMPORTANT

Remember to set the correct permissions for the /etc/hosts file before running the application.

⁠Running the Application

docker run --rm --name hostcontrol -it -v /etc/hosts:/opt/hosts -v /home/{your_user}/.host_control:/opt/host_control_db nunesfd/hostcontrol

⁠Creating an Alias (optional but very useful)

alias hostcontrol='command here'

⁠Details

⁠--rm

This option instructs Docker to automatically remove the container when it is stopped.

⁠--name hostcontrol

The --name option allows you to assign a specific name to the container.

⁠-it

This option is a combination of two options:

• -i (interactive): keeps standard input (stdin) open, even if not attached to a terminal.
• -t (terminal): allocates a pseudo-terminal, which allows you to interact with the application in a terminal environment. Together, these options make it possible to use the application interactively.

⁠-v /etc/hosts:/opt/hosts

The -v option creates a volume that mounts a directory or file from the host's filesystem inside the container. In this case:

• /etc/hosts: is the hosts file of the host operating system.
• /opt/hosts: is the path inside the container.

⁠-v /home/{your_user}/.host_control:/opt/host_control_db

This is another volume option:

• /home/{your_user}/.host_control: is the directory on the host operating system where the application data will be stored. (This location can be changed according to your preference)
• /opt/host_control_db: is the path inside the container where the data will be accessible.
