- Appveyor
- Dockerfile

## Node.js

- CircleCI
- `grafana/build-container`
- Appveyor
- Dockerfile

## Where to make changes

### CircleCI

Our builds run on CircleCI through our build script.

#### Files

- `.circleci/config.yml`.

#### Dependencies

- nodejs
- golang
- grafana/build-container (our custom docker build container)

### grafana/build-container

The main build step (in CircleCI) is built using a custom build container that comes pre-baked with some of the necessary dependencies.

Link: [grafana-build-container](https://github.com/grafana/grafana-build-container)

#### Dependencies

- fpm
- nodejs
- golang
- crosscompiling (several compilers)

### Appveyor

Master and release builds trigger test runs on Appveyors build environment so that tests will run on Windows.

#### Files:

- `appveyor.yml`

#### Dependencies

- nodejs
- golang

### Dockerfile

There is a Docker build for Grafana in the root of the project that allows anyone to build Grafana just using Docker.

#### Files

- `Dockerfile`

#### Dependencies

- nodejs
- golang

### Local developer environments

Please send out a notice in the grafana-dev slack channel when updating Go or Node.js to make it easier for everyone to update their local developer environments.
