#15556 We will need to pay attention when releasing fleet (the github actions were modified to use the local file now). Should be reviewed by commits (first commit is the actual adding of the `version.go` file) - [X] Manual QA for all new/changed functionality Manually tested the following: - `Settings -> My account` on the UI and checked the `/version` endpoint response. (Or also visiting https://localhost:8080/version on a browser). - Ran `make fleetctl fleet`, `./build/fleetctl --version` and `./build/fleet version`.

|
Package version provides utilities for displaying version information about a Go application.
|
|
|
|
To use this package, a program would set the package variables at build time, using the
|
|
-ldflags go build flag.
|
|
|
|
Example:
|
|
|
|
go build -ldflags "-X github.com/fleetdm/fleet/v4/server/version.version=1.0.0"
|
|
|
|
Available values and defaults to use with ldflags:
|
|
|
|
version = "unknown"
|
|
branch = "unknown"
|
|
revision = "unknown"
|
|
goVersion = "unknown"
|
|
buildDate = "unknown"
|
|
buildUser = "unknown"
|
|
appName = "unknown"
|
|
|
