Default Domino Environment Variables Glossary - Domino

Domino automatically injects the following environment variables whenever it runs your code as part of the context of your run. Using these variables, you can create artifacts or results, such as a report mentioning the run number. Default variables are not available to use in the Model Manager.

`AWS_SHARED_CREDENTIALS_FILE`	Path to your AWS credential file to connect to additional AWS resources (for example, S3, Redshift). See AWS credential propagation.
`DOMINO_API_HOST`	Use this to use the Domino API to access another project.
`DOMINO_ARTIFACTS_DIR`	Directory where Artifacts files system is accessed.
`DOMINO_DATASETS_DIR`	Directory where Datasets are accessed.
`DOMINO_GROUP`	Value of the default Linux group name in the container, that is `ubuntu`.
`DOMINO_GROUP_ID`	Value of default Linux group ID in the container, that is `12574`.
`DOMINO_HARDWARE_TIER_ID`	Hardware tier the current run is executing on (new in 1.42).
`DOMINO_IMPORTED_ARTIFACTS_DIR`	Directory where imported Artifacts file systems are accessed.
`DOMINO_IMPORTED_CODE_DIR`	Directory where imported code repositories are accessed.
`DOMINO_IMPORTED_DATA_DIR`	Directory where imported Datasets are accessed.
`DOMINO_IS_GIT_BASED`	Boolean value indicating if the Project is Git-based.
`DOMINO_IS_LOCAL_DATA_PLANE`	Boolean value indicating if Datasets are associated with a local data plane.
`DOMINO_IS_WORKFLOW_JOB`	Boolean value indicating if the job was orchestrated via a Flow.

`DOMINO_TRAINING_SET_PATH`	Directory where Domino Model Monitoring training sets are accessed.
`DOMINO_USER`	Value of the default Linux username in the container, that is `ubuntu`.
`DOMINO_USER_API_KEY`	This variable is sunsetting; use the API Proxy for Domino API authentication instead.
`DOMINO_USER_ID`	Value of the default Linux user ID in the container, that is `12674`.
