## 实践优化

### 1.版本号内置在程序里面，运行和部署程序的时候，可以用来知晓当前发布和部署的程序是什么版本
#### 1.1 入口 main.go
```go
package main

import (
	"flag"
	"fmt"
)

var (
	GitTag    = "2000.01.01.release"
	BuildTime = "2000-01-01T00:00:00+0800"
)

func main() {
	version := flag.Bool("v", false, "version")
	flag.Parse()

	if *version {
		fmt.Println("Git Tag: " + GitTag)
		fmt.Println("Build Time: " + BuildTime)
	}
}
```
#### 1.2 Makefile
```makefile
# This is how we want to name the binary output
OUTPUT=main

# These are the values we want to pass for Version and BuildTime
GITTAG=`git describe --tags`
BUILD_TIME=`date +%FT%T%z`

# Setup the -ldflags option for go build here, interpolate the variable values
LDFLAGS=-ldflags "-X main.GitTag=${GITTAG} -X main.BuildTime=${BUILD_TIME}"

all:
    go build ${LDFLAGS} -o ${OUTPUT} main.go
```
#### 1.3 程序部署的时候，通过git tag取代码，直接 make all就可以了。
