How to use the Great Expectation Docker images¶
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:
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.
Pull the Docker image down, e.g.:
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_expectationsdirectory 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
