如何将grafana仪表板json复制到EC2实例？

In my use case I am using influxdb and grafana for monitoring. When I launch the new instance I want the dashbboard to setup programmatically. I mean copying the exported json to some location.

I am not sure where to copy the dashboard json file after installing grafana.

Or do I need to make an api call with the json. I am using golang in the backend. So I can do that through an API call.

I am fairly new to grafana. Could someone help me with this?

You have to do it through the API. The documentation for the dashboard can be found here. To get started you will probably need to create an API token, see here for more details.

In your case, you just need to import a json file. Here is an example with curl:

curl -H "Content-Type: application/json" -H "Authorization: Bearer <your API Token>" -X POST --data '{
  "dashboard": {
    "id": null,
    "title": "Production Overview",
    "tags": [ "templated" ],
    "timezone": "browser",
    "rows": [
      {
      }
    ],
    "schemaVersion": 6,
    "version": 0
  },
  "overwrite": false
}' http://localhost:3000/api/dashboards/db
