Configuration
The configuration controls all aspects of EOS: optimization, prediction, measurement, and energy management.
Storing Configuration
EOS stores configuration data in a nested structure
. Note that configuration changes inside EOS
are updated in memory, meaning all changes will be lost upon restarting the EOS REST server if not
saved to the EOS configuration file
.
Some configuration keys
are read-only and cannot be altered. These keys are either set up by other
means, such as environment variables, or determined from other information.
Several endpoints of the EOS REST server allow for the management and retrieval of configuration data.
Save Configuration File
Use endpoint PUT /v1/config/file
to save the current configuration to the
EOS configuration file
.
Load Configuration File
Use endpoint POST /v1/config/reset
to reset the configuration to the values in the
EOS configuration file
.
Configuration Sources and Priorities
The configuration sources and their priorities are as follows:
Settings
: Provided during runtime by the REST interfaceEnvironment Variables
: Defined at startup of the REST server and during runtimeEOS Configuration File
: Read at startup of the REST server and on requestDefault Values
Runtime Config Updates
The EOS configuration can be updated at runtime. Note that those updates are not persistent
automatically. However it is possible to save the configuration to the EOS configuration file
.
Use the following endpoints to change the current runtime configuration:
PUT /v1/config
: Update the entire or parts of the configuration.
Environment Variables
All configuration keys
can be set by environment variables prefixed with EOS_
and separated by
__
for nested structures. Environment variables are case insensitive.
EOS recognizes the following special environment variables (case sensitive):
EOS_CONFIG_DIR
: The directory to search for an EOS configuration file.EOS_DIR
: The directory used by EOS for data, which will also be searched for an EOS configuration file.
EOS Configuration File
The EOS configuration file provides persistent storage for configuration data. It can be modified directly or through the REST interface.
If you do not have a configuration file, it will be automatically created on the first startup of the REST server in a system-dependent location.
To determine the location of the configuration file used by EOS, ask the REST server. The endpoint
GET /v1/config
provides the general.config_file_path
configuration key.
EOS searches for the configuration file in the following order:
The directory specified by the
EOS_CONFIG_DIR
environment variableThe directory specified by the
EOS_DIR
environment variableA platform-specific default directory for EOS
The current working directory
The first configuration file available in these directories is loaded. If no configuration file is found, a default configuration file is created, and the default settings are written to it. The location of the created configuration file follows the same order in which EOS searches for configuration files, and it depends on whether the relevant environment variables are set.
Use the following endpoints to interact with the configuration file:
PUT /v1/config/file
: Save the current configuration to the configuration file.PUT /v1/config/reset
: Reload the configuration file, all unsaved runtime configuration is reset.
Default Values
Some of the configuration keys
have default values by definition. For most of the
configuration keys
the default value is just None
, which means no default value.
Configuration Table
Settings for common configuration
General configuration to set directories of cache and output files and system location (latitude
and longitude).
Validators ensure each parameter is within a specified range. A computed property, timezone
,
determines the time zone based on latitude and longitude.
Attributes: latitude (Optional[float]): Latitude in degrees, must be between -90 and 90. longitude (Optional[float]): Longitude in degrees, must be between -180 and 180.
Properties: timezone (Optional[str]): Computed time zone string based on the specified latitude and longitude.
Validators:
validate_latitude (float): Ensures latitude
is within the range -90 to 90.
validate_longitude (float): Ensures longitude
is within the range -180 to 180.
