Talos

To expose cached datasets via Talos APIs, follow the below to use Flash as the source for Talos API.

Pre-requisites¶

Before moving on to the steps, please ensure you meet the following requirements.

Flash set up
Docker initialization

Steps¶

Create a repository, open the repository with a code editor (VS Code), and create a config.yaml manifest file and copy the below code. Update the name, description, version, DataOS context, Flash as source type, and source Flash name.

name: flash
description: A talos-flash app
version: 0.1.6
auth:
  heimdallUrl: https://liberal-donkey.dataos.app/heimdall
logLevel: 'DEBUG'
sources:
  - name: flash # source name
    type: flash
    flashName: 'public:flash-service'

In the same repository, create docker-compose.yaml manifest file, copy the below-provided code, and update the volumes path /home/iamgroot/Desktop/talos-examples/lens with the actual path of your repository, add your DataOS username and DataOS API key in DATAOS_RUN_AS_USER and DATAOS_RUN_AS_APIKEY respectively.

version: "2.2"
services:
  talos:
    image: rubiklabs/talos:0.1.6
    ports:
      - "3000:3000"
    volumes:
      - .:/etc/dataos/work
    environment:
      DATAOS_RUN_AS_USER: ${{iamgroot}}
      DATAOS_RUN_AS_APIKEY: ${{Dyiuyuidy98837686bbdhkjhugIPOPHGgGHTIOnsd68FH=}}
      DATAOS_FQDN: liberal-donkey.dataos.app
    tty: true

Create a folder named apis inside the same repository, inside apis create the files customer.sql which will contain the SQL query, and customer.yaml to define the path to access cached data in your API as shown below.
```
SELECT * FROM mycustomer LIMIT 20
```
```
urlPath: /flash/customers
description: list customers from customer table
source: flash
```
Now apply the Talos service as mentioned here.
