Guide to Upgrading Dependencies

Upgrading Go or Node.js requires making changes in many different files. See below for a list and explanation for each.

Go

• CircleCi
• grafana/build-container
• Appveyor
• Dockerfile

Node.js

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

Go Dependencies

The Grafana project uses Go modules to manage dependencies on external packages. This requires a working Go environment with version 1.11 or greater installed.

All dependencies are vendored in the vendor/ directory.

Note: Since most developers of Grafana still use the GOPATH we need to specify GO111MODULE=on to make go mod and got get work as intended. If you have setup Grafana outside of the GOPATH on your machine you can skip GO111MODULE=on when running the commands below.

To add or update a new dependency, use the go get command:

# The GO111MODULE variable can be omitted when the code isn't located in GOPATH.
# Pick the latest tagged release.
GO111MODULE=on go get example.com/some/module/pkg

# Pick a specific version.
GO111MODULE=on go get example.com/some/module/pkg@vX.Y.Z

Tidy up the go.mod and go.sum files and copy the new/updated dependency to the vendor/ directory:

# The GO111MODULE variable can be omitted when the code isn't located in GOPATH.
GO111MODULE=on go mod tidy

GO111MODULE=on go mod vendor

You have to commit the changes to go.mod, go.sum and the vendor/ directory before submitting the pull request.

Node.js Dependencies

Updated using yarn.

• package.json

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

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.
