Config Reference

The sake.yaml config is based on the following concepts:

  • servers are servers, local or remote, that have a host
  • tasks are shell commands that you write and then run for selected servers
  • specs are configs that alter task execution and output
  • targets are configs that provide shorthand filtering of servers when executing tasks
  • themes are used to modify the output of sake commands
  • env are environment variables that can be defined globally, per server and per task

Specs, targets and themes come with a default setting that the user can override.

Check the files and environment section to see how the config file is loaded.

Below is a config file detailing all of the available options and their defaults.

Files

When running a command, sake will check the current directory and all parent directories for the following files: sake.yaml, sake.yml, .sake.yaml, .sake.yml .

Additionally, it will import (if found) a config file from:

  • Linux: $XDG_CONFIG_HOME/sake/config.yaml or $HOME/.config/sake/config.yaml if $XDG_CONFIG_HOME is not set.
  • Darwin: $HOME/Library/Application/sake

Both the config and user config can be specified via flags or environments variables.

Environment

SAKE_CONFIG
    Override config file path

SAKE_USER_CONFIG
    Override user config file path

SAKE_SSH_CONFIG
    Override ssh config file path

SAKE_KNOWN_HOSTS_FILE
    Override known_hosts file path

NO_COLOR
    If this env variable is set (regardless of value) then all colors will be disabled
