Shell Fleet Agent installer for Ubuntu and macOS
===============================================

  curl -fsSL https://filesv.vnstech.cloud/install_agent | sudo -E bash

Default hub:
  https://agent.vnstech.cloud

Ubuntu proxy auto-detection priority:
  1. SHELLFLEET_PROXY
  2. apt config files: /etc/apt/apt.conf and /etc/apt/apt.conf.d/*
     Examples supported:
       Acquire::http::Proxy "http://proxy.company.local:3128";
       Acquire::https::Proxy "http://proxy.company.local:3128";
  3. /etc/environment HTTP_PROXY / HTTPS_PROXY
  4. environment variables HTTP_PROXY / HTTPS_PROXY / ALL_PROXY

  2. scutil --proxy

Override proxy:
  curl -fsSL https://filesv.vnstech.cloud/install_agent | \
    SHELLFLEET_PROXY=http://proxy.company.local:3128 sudo -E bash

Override group:
  curl -fsSL https://filesv.vnstech.cloud/install_agent | \
    SHELLFLEET_GROUP=/Customer/Prod sudo -E bash

During enrollment, enter a Shell Fleet admin or agent-role account.

Note: the installer reads enrollment username/password from /dev/tty, so the one-command pipe still allows normal interactive typing.

Ubuntu service:
  systemctl status shellfleet-agent
  journalctl -u shellfleet-agent -f

macOS service:
  launchctl print system/com.shellfleet.agent
  tail -f /var/log/shellfleet-agent.log
