Build info

A package for getting application build metadata information from multiple sources

Usage

go get -u github.com/robotomize/buildinfo

Example

logger, _ := zap.NewProduction()
sugar := logger.Sugar()

lg := sugar.With(
zap.String("build_tag", buildinfo.Tag()), zap.String("build_time", buildinfo.Time()),
zap.String("build_sha", buildinfo.SHA()),
)

Use flags

./exampleapp -buildtag=$(git describe --tags --abbrev=0) -buildtime=$(date -u '+%Y-%m-%d-%H:%M') -buildsha=$(git rev-parse HEAD)

Use buildinfo ldflags

go build -ldflags "-X github.com/robotomize/buildinfo.BuildTag=v0.4.0 \
-X github.com/robotomize/buildinfo.BuildTime=2022-05-27 \
-X github.com/robotomize/buildinfo.BuildSHA=e4601a766ce364b65427cbcfd3f0cbfe233725af"

fmt.Println(buildinfo.Tag(),buildinfo.Time(),buildinfo.SHA())

Use ldflags and Set method

go build -ldflags "-X main.BuildTag=v0.4.0 -X main.BuildTime=2022-05-27 -X main.BuildSHA=e4601a766ce364b65427cbcfd3f0cbfe233725af"

var (
    	BuildTag string
	BuildTime string
	BuildSHA string
)

buildinfo.Set(&BuildTag, &BuildTime, &BuildSHA)
fmt.Println(buildinfo.Tag(),buildinfo.Time(),buildinfo.SHA())

Order

• Set method
• build flags
• ldflags
• -buildvcs=true
