Set up development environment

The create-plugin tool includes a development environment featuring Docker. It allows you to start an instance of the Grafana application for plugin developers against which you can code.

info

It's not necessary to sign a plugin during development. The Docker development environment that is scaffolded with @grafana/create-plugin will load the plugin without a signature. This is because it is configured by default to run in development mode.

Why use the Docker environment

We have chosen to use Docker because it simplifies the process of creating, deploying, and running applications. It allows you to create consistent and isolated environments for your plugin. This makes it easy to manage dependencies and ensure that the plugin runs the same way across different machines.

With the create-plugin tool, the Docker container is configured with the necessary variables to allow easy access to Grafana and to load plugins without the need for them to be signed. The plugin tool also adds a live reload feature that allows you to make your frontend code changes to trigger refreshes in the browser.

Get started with Docker

To start your plugin development project, run the following commands in the order listed:

  1. npm install: Installs frontend dependencies.
  2. npm run dev: Builds and watches the plugin frontend code.
  3. mage -v build:linux: Builds the plugin backend code. Rerun this command every time that you edit your backend files.
  4. npm run server: Starts a Grafana development server running on http://localhost:3000. Restart this command each time you run mage to run your new backend code.

Configure the Grafana version

To test a plugin across different versions of Grafana, set an environment variable. Use GRAFANA_VERSION to set the Grafana version:

GRAFANA_VERSION=10.0.0 npm run server

Configure the Grafana image

The default Docker image in the plugin tool is grafana-enterprise. If you want to override this image, alter the docker-compose.yaml by changing the grafana_image build argument like so:

docker-compose.yaml
version: '3.7'

services:
grafana:
container_name: 'myorg-basic-app'
build:
context: ./.config
args:
grafana_version: ${GRAFANA_VERSION:-9.1.2}
grafana_image: ${GRAFANA_IMAGE:-grafana}

This example assigns the environment variable GRAFANA_IMAGE to the build arg grafana_image with a default value of grafana. This gives you the option to set the value when running docker-compose commands.
