Creating config

Developing a DipDup indexer begins with creating a YAML config file. You can find a minimal example to start indexing on the Quickstart page.

General structure

DipDup configuration is stored in YAML files of a specific format. By default, DipDup searches for dipdup.yml file in the current working directory, but you can provide any path with a -c CLI option.

DipDup config file consists of several logical blocks:

Headerspec_version*14.15. spec_version
package*14.12. package
Inventorydatabase14.5. database
contracts14.3. contracts
datasources14.6. datasources
custom14.4. custom
Index definitionsindexes14.9. indexes
templates14.16. templates
Hook definitionshooks14.8. hooks
jobs14.10. jobs
Integrationshasura14.7. hasura
sentry14.14. sentry
prometheus14.13. prometheus
Tunablesadvanced14.2. advanced
logging14.11. logging

Header contains two required fields, package and spec_version. They are used to identify the project and the version of the DipDup specification. All other fields in the config are optional.

Inventory specifies contracts that need to be indexed, datasources to fetch data from and the database to store data in.

Index definitions define the index templates that will be used to index the contract data.

Hook definitions define callback functions that will be called manually or on schedule.

Integrations are used to integrate with third-party services.

Tunables affect the behavior of the whole framework.

Merging config files

DipDup allows you to customize the configuration for a specific environment or a workflow. It works similar to docker-compose, but only for top-level sections. If you want to override a nested property, you need to recreate a whole top-level section. To merge several DipDup config files, provide the -c command-line option multiple times:

dipdup -c dipdup.yml -c dipdup.prod.yml run

Run config export command if unsure about the final config used by DipDup.
