Cockpit – sysadmin login session in a web browser

Cockpit is a service for Linux that provides a web-based interface for managing and monitoring hosts.

Cockpit makes Linux discoverable, allowing sysadmins to easily perform tasks such as starting containers, storage administration, network configuration, inspecting logs and so on.

Jumping between the terminal and the web tool is no problem. A service started via Cockpit can be stopped via the terminal. Likewise, if an error occurs in the terminal, it can be seen in the Cockpit journal interface.

You can also easily add other machines that have Cockpit installed and are accessible via SSH and jump between these hosts.

Cockpit is free and open source software.

Features include:

  • Graphical and interface designers are involved in the project.
  • Modular and can be extended by installing extra modules. You can also develop your own modules.
  • Supports multiple servers from a single dashboard.
  • Unobtrusive –  works alongside other management tools without causing issues.
  • Uses a systemd socket, and doesn’t use memory when not in use.
  • Builds upon existing functionality; it doesn’t require a configuration by default.
  • Doesn’t store the state or data of servers anywhere. It uses the same API command-line tools use.
  • No special privileges and doesn’t run as root. It creates a session as the logged in user and has the same permissions as that user. So, to perform administrative tasks, the user needs permission to use sudo or PolicyKit to escalate privileges.
  • Supports the following tasks (and more):
    • Inspect and change network settings.
    • Configure a firewall.
    • Manage storage (including RAID and LUKS partitions).
    • Create and manage virtual machines.
    • Download and run containers.
    • Browse and search system logs.
    • Inspect a system’s hardware.
    • Upgrade software.
    • Keep tabs on performance.
    • Manage user accounts.
    • Inspect and interact with systemd-based services.
    • Use a terminal on a remote server in your local web browser.
    • Switch between multiple Cockpit servers.
    • Extend Cockpit’s functionality by installing a growing list of apps and add-ons.
