Configuration¶
Command Line Configuration¶
habitat daemons takes zero or one command line arguments: an optional filename specifying the configuration to use, or ”./habitat.yml” by default:
./bin/parser
# or
./bin/parser /path/to/config.yml
Configuration File¶
The configuration file is written in YAML as several key: value pairs. Various habitat components may require certain pieces of configuration; where possible these are all documented here.
habitat-wide Configuration¶
couch_uri: "http://localhost:5984"
couch_db: habitat
log_stderr_level: DEBUG
log_file_level: INFO
couch_uri and couch_db specify how to connect to the CouchDB database. The URI may contain authentication details if required.
log_stderr_level and log_file_level set the log levels for a log file and the stderr output and may be “NONE”, “ERROR”, “WARN”, “INFO” or “DEBUG”.
parser configuration¶
parser:
certs_dir: "/path/to/certs"
modules:
- name: "UKHAS"
class: "habitat.parser_modules.ukhas_parser.UKHASParser"
parserdaemon:
log_file: "/path/to/parser/log"
Inside the parser and parserdaemon objects:
- certs_dir specifies where the habitat certificates (used for code signing) are kept
- log_file specifies where the parser daemon should write its log file to
- modules gives a list of all the parser modules that should be loaded, with a name (that must match names used in flight documents) and the Python path to load.
This configuration is used by habitat.parser and habitat.parser_daemon.
loadable_manager configuration¶
loadables:
- name: "sensors.base"
class: "habitat.sensors.base"
- name: "sensors.stdtelem"
class: "habitat.sensors.stdtelem"
- name: "filters.common"
class: "habitat.filters"
Inside the loadables object is a list of modules to load and the short name they should be loaded against. This is used by habitat.loadable_manager.
