Create data-container

Overview

In order to Spawn a database to work against, you'll need to create a Data Container. A Data Container is created from a Data Image.

Command

$ spawnctl create data-container --image <ImageName[:Tag]_Or_ImageID>

Tutorial

In this tutorial we will create a Data Image and then use it to create a Data Container.

As a prerequisite you should've followed the instructions to install spawnctl

Create a file development.yaml with your Data Image specifications.
```
sourceType: empty
name: dev
engine: postgresql
```
In this case we want to create a PostgreSQL Data Image that is completely empty and is named dev.

Run the following command to create a Data Image.

$ spawnctl create data-image -f ./development.yaml
Data image 'dev' created!

You can verify your Data Image by running the following command.

$ spawnctl get data-images
NAME  IMAGE ID  ENGINE      STATUS  MESSAGE  CREATED
dev   10001     PostgreSQL  2       Created  2 minutes ago

Create a Data Container from the newly created Data Image.

$ spawnctl create data-container --image dev
Data container 'dev-rambbomj' created!
-> Host=instances.spawn.cc;Port=53223;User ID=<some_user_id>;Password=<some_password>;

You can verify your Data Container was properly created by running the following command.

$ spawnctl get data-containers
NAME          CONTAINER ID  REVISION  STATUS  MESSAGE  ENGINE      CREATED
dev-cp5rye3n  10001         rev.0     2       Running  PostgreSQL  1 minute ago

You should now be able to connect to your database and execute queries.

In this example we connect to the PostgreSQL Data Container (database) using psql.

$ psql -h instances.spawn.cc -p 53223 -U <some_user_id>
Password for user <some_user_id>:
psql (10.5, server 11.0 (Debian 11.0-1.pgdg90+2))
