Configuration of the Cockpit Dogu

Prerequisite

Configuration options

The Cockpit Dogu is configured via the registry. There are several ways to configure values in the registry. In short, you can:

  1. Configure a dogu with kubectl edit -n ecosystem configmap cockpit-config (recommended)
  2. Update the configuration values using a blueprint

  • Content: Limits the memory (RAM) of the Docker container for Cockpit
  • Data type: Binary memory specification
  • Valid values: Integer followed by [b,k,m,g] (byte, kibibyte, mebibyte, gibibyte)
  • Example: 1750m = 1750 MebiByte
Physical swap limit
  • Configuration key path: container_config/swap_limit
  • Content: Limits the swap of the Docker container for Cockpit
  • Data type: Binary memory specification
  • Valid values: Integer followed by [b,k,m,g] (byte, kibibyte, mebibyte, gibibyte)

Global proxy usage

Cockpit uses the global CES proxy configuration from config/_global/proxy for outbound HTTP requests from the newsfeed widget.

The following global keys are evaluated during startup:

  • proxy/enabled
  • proxy/server
  • proxy/port
  • proxy/username (optional)
  • proxy/password (optional)
  • proxy/no_proxy_hosts (optional but highly recommended if proxy/enabled=true)

If the proxy is enabled, Cockpit exports the standard environment variables HTTP_PROXY, HTTPS_PROXY, http_proxy, https_proxy, NO_PROXY, and no_proxy for the Node.js process.
