## Installation
Head to [docs.grafana.org](http://docs.grafana.org/installation/) and [download](https://grafana.com/get)
the latest release.

If you have any problems please read the [troubleshooting guide](http://docs.grafana.org/installation/troubleshooting/).

## Documentation & Support
Be sure to read the [getting started guide](http://docs.grafana.org/guides/gettingstarted/) 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](https://grafana.com/grafana/download)

### Dependencies

- Go (Latest Stable)
- Node.js LTS

### Building the backend
```bash
go get github.com/grafana/grafana
cd $GOPATH/src/github.com/grafana/grafana
go run build.go setup
go run build.go build
```

### Building frontend assets

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

To build the assets, rebuild on file change, and serve them by Grafana's webserver (http://localhost:3000):
```bash
npm install -g yarn
yarn install --pure-lockfile
yarn watch
```

Build the assets, rebuild on file change with Hot Module Replacement (HMR), and serve them by webpack-dev-server (http://localhost:3333):
```bash
yarn start
# OR set a theme
env GRAFANA_THEME=light yarn start
```
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
```bash
yarn jest
```

### Recompile backend on source change

To rebuild on source change.
```bash
go get github.com/Unknwon/bra
bra run
```

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

### Building a Docker image

There are two different ways to build a Grafana docker image. If you're 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 let limit of Memory bigger than 2 GiB (at docker -> Preferences -> Advanced), otherwize you may faild at `grunt build`

### 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
1. custom.ini

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

### Running tests

#### Frontend
Execute all frontend tests
```bash
yarn test
```

Writing & watching frontend tests

- Start watcher: `yarn jest`
- Jest will run all test files that end with the name ".test.ts"

#### Backend
```bash
# Run Golang tests using sqlite3 as database (default)
go test ./pkg/...

# Run Golang tests using mysql as database - convenient to use /docker/blocks/mysql_tests
GRAFANA_TEST_DB=mysql go test ./pkg/...

# Run Golang tests using postgres as database - convenient to use /docker/blocks/postgres_tests
GRAFANA_TEST_DB=postgres go test ./pkg/...
```
