Top-like interface for container metrics

ctop provides a concise and condensed overview of real-time metrics for multiple containers:

as well as a single container view for inspecting a specific container.

ctop comes with built-in support for Docker and runC; connectors for other container and cluster systems are planned for future releases.

Usage

ctop requires no arguments and uses Docker host variables by default. See connectors for further configuration options.

Config file

While running, use S to save the current filters, sort field, and other options to a default config path (~/.config/ctop/config on XDG systems, else ~/.ctop).

Config file values will be loaded and applied the next time ctop is started.
