Based on the information provided in the extracts, you can use the following commands to run your setup: First, you need to pull the Ory Keto Docker image:

bash docker pull oryd/keto:<version-you-want>

Then, you can run the Ory Keto Docker image:

bash docker run --rm -it oryd/keto:<version-you-want> help

To start the example using

docker-compose

, you can use the following command:

bash docker-compose -f docker-compose-postgres.yml up

Please replace

<version-you-want>

with the version of Ory Keto you want to use. However, the extracts do not provide specific information on how to use a

keto.yaml

file which contains the namespaces in a Docker command. For more detailed instructions, you may want to refer to the [Ory Keto documentation](https://www.ory.sh/docs/keto/).

I'm sorry, but the provided extracts do not contain information about the latest version of Ory Keto. You can check the latest version by visiting the [Ory Keto GitHub repository](https://github.com/ory/keto) or the [Ory documentation](https://www.ory.sh/docs/keto/).

I'm sorry, but the provided extracts do not contain information about the latest stable version of Ory Keto for self-hosting. You can check the latest stable version by visiting the [Ory Keto GitHub repository](https://github.com/ory/keto) or the [Ory documentation](https://www.ory.sh/docs/keto/).

In Ory Keto, namespaces are defined as TypeScript classes in the Ory Permission Language. The name of the namespace should be in upper camel case, for example:

User

,

Document

,

Folder

,

AccessKey

. Here is an example of how you might define namespaces in a TypeScript file:

typescript import { Namespace, Context } from "@ory/keto-namespace-types"      class User implements Namespace {}   class Document implements Namespace {}   class Folder implements Namespace {}

In this case, if you want to name your file as

namespace.keto.ts

, you can do so. The important part is the content of the file, where you define your namespaces. Source: [Ory Keto - Concepts - Namespaces](https://www.ory.sh/docs/keto/concepts/namespaces)

In the

keto.yaml

configuration file, namespaces are defined under the

namespaces

key. Each namespace is represented as an object with an

id

and a

name

. The

name

is the name of the namespace. Here is an example of how you might define namespaces in a

keto.yaml

file:

yaml namespaces:    - id: 0      name: groups    - id: 1      name: reports

In this example, two namespaces are defined:

groups

and

reports
