Grafana Circle CI Go Report Card

Website | Twitter | Community & Forum

Grafana is an open source, feature rich metrics dashboard and graph editor for Graphite, Elasticsearch, OpenTSDB, Prometheus and InfluxDB.

Installation

Head to docs.grafana.org for documentation or grafana.com/get to download the latest release.

Documentation & Support

Be sure to read the Getting Started guide and the other feature guides.

Run from master

If you want to build a package yourself, or contribute - here is a guide for how to do that. You can always find the latest master builds here.

Dependencies

  • Go (Latest Stable)
  • Node.js LTS
    • yarn [npm install -g yarn]

Get the project

The project located in the go-path will be your working directory.

go get github.com/grafana/grafana
cd $GOPATH/src/github.com/grafana/grafana

Run and rebuild on source change

Backend

To run the backend and rebuild on source change:

make run

Frontend

Install front-end dependencies first:

yarn install --pure-lockfile

Rebuild on file change, and serve them by Grafana's webserver (http://localhost:3000):

yarn start

Build the assets, rebuild on file change with Hot Module Replacement (HMR), and serve them by webpack-dev-server (http://localhost:3333):

yarn start:hot
# OR set a theme
env GRAFANA_THEME=light yarn start:hot

Note: HMR for Angular is not supported. If you edit files in the Angular part of the app, the whole page will reload.

Run tests and rebuild on source change:

yarn jest

Open grafana in your browser (default: e.g. http://localhost:3000) and login with admin user (default: user/pass = admin/admin).

Building

The backend

go run build.go setup
go run build.go build

Frontend assets

For this you need Node.js (LTS version).

yarn install --pure-lockfile

Building a Docker image

There are two different ways to build a Grafana docker image. If your machine is setup for Grafana development and you run linux/amd64 you can build just the image. Otherwise, there is the option to build Grafana completely within Docker.

Run the image you have built using: docker run --rm -p 3000:3000 grafana/grafana:dev

Building on linux/amd64 (fast)

  1. Build the frontend go run build.go build-frontend.
  2. Build the docker image make build-docker-dev.

The resulting image will be tagged as grafana/grafana:dev.

Building anywhere (slower)

Choose this option to build on platforms other than linux/amd64 and/or not have to setup the Grafana development environment.

  1. make build-docker-full or docker build -t grafana/grafana:dev.

The resulting image will be tagged as grafana/grafana:dev.

Notice: If you are using Docker for MacOS, be sure to set the memory limit to be larger than 2 GiB (at docker -> Preferences -> Advanced), otherwise grunt build may fail.

Development

Dev config

Create a custom.ini in the conf directory to override default configuration options. You only need to add the options you want to override. Config files are applied in the order of:

  1. grafana.ini
  2. custom.ini

In your custom.ini uncomment (remove the leading ;) sign. And set app_mode = development.

Running tests

Frontend

Execute all frontend tests:

yarn test

Write and watch frontend tests:

  • Start watcher: yarn jest.
  • Jest runs all test files that end with the name ".test.ts".

Backend

# Run Golang tests using sqlite3 as database (default)
go test ./pkg/...
Running the MySQL or Postgres backend tests:

Run these by setting GRAFANA_TEST_DB in your environment.

  • GRAFANA_TEST_DB=mysql to test MySQL
  • GRAFANA_TEST_DB=postgres to test Postgres

Follow the instructions in ./devenv to spin up test containers running the appropriate databases with docker-compose

  • Use docker/blocks/mysql_tests or docker/blocks/postgres_tests as appropriate.
# MySQL
# Tests can only be ran in one Go package at a time due to clashing db queries. To run MySQL tests for the "pkg/services/sqlstore" package, run:
GRAFANA_TEST_DB=mysql go test ./pkg/services/sqlstore/...

# Or run all the packages using the circle CI scripts. This method will be slower as the scripts will run all the tests, including the integration tests.
./scripts/circle-test-mysql.sh
# Postgres
# Tests can only be ran in one Go package at a time due to clashing db queries. To run Postgres tests for the "pkg/services/sqlstore" package, run:
GRAFANA_TEST_DB=postgres go test ./pkg/services/sqlstore/...

# Or run all the packages using the circle CI scripts. This method will be slower as the scripts will run all the tests, including the integration tests.
./scripts/circle-test-postgres.sh

End-to-end

Execute all end-to-end tests:

yarn e2e-tests

Execute all end-to-end tests using using a specific url:

ENV BASE_URL=http://localhost:3333 yarn e2e-tests

Debugging all end-to-end tests (BROWSER=1 starts the browser and SLOWMO=1 delays each puppeteer operation by 100ms):

ENV BROWSER=1 SLOWMO=1 yarn e2e-tests

Data source and dashboard provisioning

Here you can find helpful scripts and docker-compose setup that will populate your dev environment for quicker testing and experimenting.
