Configuration files¶
This section presents some configuration files that can be used in the installation steps of datacube-ows.
ows_cfg.py¶
The ows_cfg.py file was created in order to give configuration flexibility to users of ODC-OWS services. With this file, all styles, metadata of the OGC services, and pre-processing applied to the data can be described through a Python dictionary. There are many options available for use. An example of this file created for BDC consumption is available in the BDC-ODC repository.
Note
To learn about all the available parameters, consult the official documentation of the ODC-OWS.
.env¶
The .env file, available at the root of the datacube-ows project, helps in the configuration of the services. This file specifies environment variables to be used by the service for connection to the database, recovery from the ows_cfg.py configuration file, and several other options such as permission to recover data from AWS. An example of this file is presented below.
# Set some default vars, you can overwrite these by creating env vars
AWS_REGION=ap-southeast-2
DB_HOSTNAME=postgres
DB_PORT=5432
DB_USERNAME=opendatacubeusername
DB_PASSWORD=opendatacubepassword
DB_DATABASE=opendatacube
OWS_CFG_FILE=./ows_test_cfg.py
AWS_NO_SIGN_REQUEST=yes
# If you want to use pydev for interactive debugging
PYDEV_DEBUG=
# Will not work with pydev
FLASK_ENV=development
prometheus_multiproc_dir=/tmp
Warning
It should be noted that the variable OWS_CFG_FILE indicates where the configuration file ows_cfg.py is located. It is recommended to keep it inside the project directory because it will be copied into the container during the build
