Configuration can be provided to Agent via the following methods:
- Reading from environment variables
- Reading from a YAML configuration file
When a configuration option is specified through both methods, environment variables take precedence over the config file.
Internally, Optimizely Agent uses the Viper library's support for configuration files and environment variables.
The default location of the config file is
config.yaml in the root directory. If you want to specify another location, use the
OPTIMIZELY_CONFIG_FILENAME environment variable:
OPTIMIZELY_CONFIG_FILENAME=/path/to/other_config_file.yaml make run
When setting the value of "nested" configuration options using environment variables, underscores denote deeper access. The following examples are equivalent ways of setting the client polling interval.
Set the polling interval in YAML:
# Setting a nested value in a .yaml file: client: pollingInterval: 120s
Set the polling interval with a shell script:
# Set environment variable for pollingInterval, nested inside client export OPTIMIZELY_CLIENT_POLLINGINTERVAL=120s
Some options can only be set via config file, and not environment variable (for details on these options, see the Configuration Options table in the main README:
