In order for Spawn to create a database to work against, you'll first need to create a data image.
For more information about data images please see data image concepts
You can specify a lifetime for a data image via the
lifetime flag. This will automatically delete your data image after the time specified, in time duration format (number followed by a unit suffix. Valid units are "h", "m", "s").
If no value is provided, your data image will have an unlimited lifetime, and will only be deleted if you explicitly request it.
If there are data containers running for the expired data image, the data image will not be removed
You can update data images after creation to alter their lifetime
To override any Tags specified in the
yaml file, use the
To override the name specified in the
.yaml file, use the
To create a data-image with a
lifetime define it in the
.yaml file or use
In this tutorial we will create a data image.
As a prerequisite you should've followed the instructions to install spawnctl
Create a file
development.yamlwith your data image specifications.sourceType: emptyname: devengine: postgresqlversion: 11.0
In this case we want to create a PostgreSQL data image that is completely empty and is named

Run the following command to create a data image.$ spawnctl create data-image -f ./development.yamlData image 'dev' (10001) created!
You can verify your data image by running the following command.$ spawnctl get data-imagesNAME IMAGE ID ENGINE STATUS MESSAGE CREATEDdev 10001 PostgreSQL 2 Created 2 minutes ago
