# Guide to upgrading dependencies
|
|
|
|
Upgrading Go or Node.js requires making changes in many different files. Refer to the following list for more information.
|
|
|
|
## Go
|
|
|
|
- Drone
|
|
- `grafana/build-container`
|
|
- Appveyor
|
|
- Dockerfile
|
|
|
|
## Node.js
|
|
|
|
- Drone
|
|
- `grafana/build-container`
|
|
- Appveyor
|
|
- Dockerfile
|
|
- `.github/workflows/publish.yml`
|
|
|
|
## Go dependencies
|
|
|
|
The Grafana project uses [Go modules](https://golang.org/cmd/go/#hdr-Modules__module_versions__and_more) to manage dependencies on external packages. This requires a working Go environment with version 1.11 or later installed.
|
|
|
|
To add or update a new dependency, use the `go get` command:
|
|
|
|
```bash
|
|
go get example.com/some/module/pkg
|
|
|
|
# Pick a specific version.
|
|
go get example.com/some/module/pkg@vX.Y.Z
|
|
```
|
|
|
|
Tidy up the `go.mod` and `go.sum` files:
|
|
|
|
```bash
|
|
go mod tidy
|
|
```
|
|
|
|
You have to commit the changes to `go.mod` and `go.sum` before you submit the pull request.
|
|
|
|
To understand what the actual dependencies of `grafana-server` are, you can run it with the `-vv` flag. Note that this command might produce an output different from `go.mod` contents, and `-vv` option is the source of truth here. The output lists the modules _compiled_ into the executable, whereas `go.mod` lists also test and weak transitive dependencies (that is, modules, used in some packages, which aren't in use by itself). If you're interested in reporting a vulnerability in a dependency module, consult the `-vv` output, maybe the "dependency" isn't actually a dependency as such.
|
|
|
|
### Upgrading dependencies
|
|
|
|
If you need to upgrade a direct or indirect dependency, you can do it like so, where _`MODULE`_ is the dependency in question: `go get -u <MODULE>`. The corresponding entry in `go.mod` should then have the version you specified. If it's an indirect dependency, the entry should have the `// indirect` comment.
|
|
|
|
To do so, execute `go mod tidy` to ensure that `go.mod` and `go.sum` are updated. If the indirect dependency turns out to not be used (transitively) by any of our packages, `go mod tidy` actually strips it from `go.mod`. In that case, you can just ignore it because ultimately it isn't used.

## Node.js dependencies
|
|
|
|
Updated using `yarn`:
|
|
|
|
- `package.json`
|
|
|
|
## Where to make changes
|
|
|
|
### Drone
|
|
|
|
Our CI builds run on Drone.
|
|
|
|
#### Files
|
|
|
|
- `.circleci/config.yml`.
|
|
|
|
#### Dependencies
|
|
|
|
- Node.js
|
|
- Go
|
|
- `grafana/build-container` (our custom Docker build container)
|
|
|
|
### grafana/build-container
|
|
|
|
The main build steps (in Drone) happen using a custom Docker image that comes pre-baked with some of the necessary dependencies.
|
|
|
|
Link: [`grafana/build-container`](https://github.com/grafana/grafana/tree/main/scripts/build/ci-build)
|
|
|
|
#### Dependencies
|
|
|
|
- fpm
|
|
- Node.js
|
|
- Go
|
|
- cross-compiling (several compilers)
|
|
|
|
### Appveyor
|
|
|
|
Main and release builds trigger test runs on the 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
|
|
|
|
It is a good practice to 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.
