This guide will help you use the official Great Expectations Docker images. This is useful if you wish to have a fully portable Great Expectations runtime that can be used locally or deployed on the cloud.
Prerequisites: This how-to guide assumes you have:
- Completed the Getting Started Tutorial
- Have a working installation of Great Expectations
- Installed Docker on your machine
First, choose which image you'd like to use by browsing the offical Great Expectations Docker image registry.
Note: We do not use the
:latest tag, so you will need to specify an exact tag.
docker pull greatexpectations/great_expectations:python-3.7-buster-ge-0.12.0
Next, we assume you have a Great Expectations project deployed at
/full/path/to/your/project/great_expectations. You need to mount the local
great_expectations directory into the container at
/usr/app/great_expectations, and from there you can run all non-interactice commands, such as running checkpoints and listing items:
docker run \-v /full/path/to/your/project/great_expectations:/usr/app/great_expectations \greatexpectations/great_expectations:python-3.7-buster-ge-0.12.0 \datasource list
If you need to run interactive
great_expectations commands, you can simply add the
-it flags for interactive mode.
docker run -it \-v /full/path/to/your/project/great_expectations:/usr/app/great_expectations \greatexpectations/great_expectations:python-3.7-buster-ge-0.12.0
