The lxc-attach command allows you to execute a command directly within the context of a running LXC container.
This is useful for troubleshooting, managing processes, or running interactive applications inside the container without requiring an SSH connection.
It utilizes the container's namespace, providing a view of the container's filesystem, process list, and network interfaces.
lxc-attach simplifies interacting with containers by providing a direct entry point, making it a powerful tool for container management and development.

Requires appropriate privileges to access the container's namespace. The command will execute within the container's security context.

Attaching to a container grants access to its internal environment. Ensure the container is properly secured and that the user executing lxc-attach has the necessary permissions.
