从 v2.5 版本开始，为提高命令解耦性，gf docker 命令默认不再执行二进制编译。推荐使用 Makefile 构建脚本组合 gf build、gf gen enums、gf docker 等命令（工程项目中提供了 make build、make enums、make docker 命令），这种方式更灵活且易于维护。

使用方式
$ gf docker -h
USAGE
gf docker [MAIN] [OPTION]
ARGUMENT
MAIN main file path for "gf build", it's "main.go" in default. empty string for no binary build
OPTION
-f, --file file path of the Dockerfile. it's "manifest/docker/Dockerfile" in default
-s, --shell path of the shell file which is executed before docker build
-b, --build binary build options before docker image build, it's "-a amd64 -s linux" in default
-tn, --tagName tag name for this docker, pattern like "image:tag". this option is required with TagPrefixes
-tp, --tagPrefixes tag prefixes for this docker, which are used for docker push. this option is required with
TagName
-p, --push auto push the docker image to docker registry if "-t" option passed
-e, --extra extra build options passed to "docker image"
-h, --help more information about this command
EXAMPLE
gf docker
gf docker -t hub.docker.com/john/image:tag
gf docker -p -t hub.docker.com/john/image:tag
gf docker main.go
gf docker main.go -t hub.docker.com/john/image:tag
gf docker main.go -t hub.docker.com/john/image:tag
gf docker main.go -p -t hub.docker.com/john/image:tag
DESCRIPTION
The "docker" command builds the GF project to a docker images.
It runs "gf build" firstly to compile the project to binary file.
It then runs "docker build" command automatically to generate the docker image.
You should have docker installed, and there must be a Dockerfile in the root of the project.自动编译并生成 Docker 镜像。MAIN 参数为可选的编译文件路径，默认为 main.go。OPTIONS 参数为可选的 docker build 命令参数及选项。
该命令会自动完成以下流程：
- 执行
gf build编译项目为二进制文件 - 执行
docker build生成镜像 - 可选执行
docker push推送镜像到仓库
前提条件：
- 系统已安装 Docker
- 项目根目录存在 Dockerfile 文件
使用示例
$ gf docker main.go -p -tn loads/gf-demos:test

2020-12-31 00:47:28.207 go build -o ./bin/linux_amd64/main main.go

...配置文件示例
推荐使用配置文件管理工具配置，在 hack/config.yaml 文件中维护。docker 命令配置示例：
gfcli:
docker:
build: "-a amd64 -s linux -p temp -ew"
tagPrefixes:
