The hcloud CLI tool can be configured using following methods:
- Configuration file
- Environment variables
- Command line flags
A higher number means a higher priority. For example, a command line flag will always override an environment variable.
The configuration file is located at ~/.config/hcloud/cli.toml by default
(On Windows: %APPDATA%\hcloud\cli.toml). You can change the location by setting
the HCLOUD_CONFIG environment variable or the --config flag. The configuration file
stores global preferences, the currently active context, all contexts and
context-specific preferences. Contexts always store a token and can optionally have
additional preferences which take precedence over the globally set preferences.
However, a config file is not required. If no config file is found, the CLI will
use the default configuration. Overriding options using environment variables allows the
hcloud CLI to function in a stateless way. For example, setting HCLOUD_TOKEN is
already enough in many cases.
You can use the hcloud config command to manage your configuration, for example
to get, list, set and unset configuration options and preferences. You can view a list
of all available options and preferences here.
