Opinionated dev environment

The environment folder has an opinionated dev environment, with a range of antimeridian dataset indexing examples. All examples can be indexed, but fail when loading.

To get the environment set up, you need to have installed Docker as well as some Python libraries:

pip install odc-apps-dc-tools datacube

Export some environment variables:

export ODC_DEFAULT_DB_HOSTNAME=localhost
export ODC_DEFAULT_DB_USERNAME=dearth
export ODC_DEFAULT_DB_PASSWORD=dearthdbpassword
export ODC_DEFAULT_DB_DATABASE=dearth
export ODC_DEFAULT_INDEX_DRIVER=postgis

Then use Make to set things up:

• make up do this in its own tab, runs PostGIS
• make init initialises the database
• make product sets up Datacube product definitions
• make index indexes examples for three products.
