Cockpit

A remote manager for GNU/Linux servers

  • Cockpit is a server manager that makes it easy to administer your GNU/Linux servers via a web browser.

  • Cockpit makes it easy for any sysadmin to perform simple tasks, such as administering storage, inspecting journals and starting and stopping services.

  • 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 monitor and administer several servers at the same time. Just add them with a single click and your machines will look after its buddies.

  • Adjust resources available to containers
    • Resource limits enforced by the CGroup subsystem in the Linux kernel
    • Adjust CPU shares
    • Assign memory limits
    • More CGroup policy controls to come
  • Stop, Start, Delete and Commit container instances
  • Run and Delete container images

Cockpit is in beta/preview at this time, but you can still try it out and help test! For more information, see the Cockpit project page.

  1. After starting your atomic host, you need to run the cockpit container:
    • `$ sudo atomic run cockpit/ws
  2. You can now use the cockpit management interface at http://yourhost:9090
