failed to read Dockerfile MacOS GoLang; Trying to create an image
问题
我在最后一行遇到了这个错误，并尝试将Dockerfile放在tmp文件夹中，但仍然得到相同的错误；我甚至尝试将Dockerfile的文件名改为大写和小写，但问题没有解决。
我的文件路径是Users/maheenk/Desktop/infra
我的Dockerfile：
#syntax=docker/dockerfile:1
#使用最新版本
FROM golang:latest
WORKDIR /app
#下载必要的Go模块
COPY go.mod ./
COPY go.sum ./
RUN go mod download
#将源代码复制到镜像中
COPY *.go ./
#在根文件系统中创建静态应用程序
RUN docker build -t internhw:latest -f .Dockerfile .
EXPOSE 8080
#当镜像用于启动容器时执行的命令
CMD ["internhw"]
我在终端中运行的命令：
docker build -t internhw:latest -f .Dockerfile .
终端的输出是：
[+] Building 0.1s (2/2) FINISHED
=> [internal] load build definition from .Dockerfile 0.1s
=> => transferring dockerfile: 2B 0.0s
=> [internal] load .dockerignore 0.0s

failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount200403056/.Dockerfile: no such file or directory
终端中运行命令ls -al的输出：

-rw-r--r-- 1 maheenk staff 2126 Apr 23 16:09 main.go
我在文件夹中添加了一个.Dockerfile（实际上是将Dockerfile复制并重命名为前面加了一个点）：
total 160
drwxrwxr-x@ 9 maheenk staff 288 Apr 24 13:03 .
drwxrwxrwx@ 111 maheenk staff 3552 Apr 24 12:43 ..

-rw-r--r--@ 1 maheenk staff 513 Apr 24 13:06 .Dockerfile
drwxr-xr-x 14 maheenk staff 448 Apr 24 13:00 .git
-rw-r--r--@ 1 maheenk staff 523 Apr 24 10:54 Dockerfile
-rw-r--r-- 1 maheenk staff 669 Apr 23 16:26 go.mod
-rw-r--r-- 1 maheenk staff 56262 Apr 23 16:26 go.sum
-rw-r--r-- 1 maheenk staff 2126 Apr 23 16:09 main.go
更新后的版本：
按照建议，我重新修改了Docker中的运行行：
#syntax=docker/dockerfile:1
FROM golang:latest
WORKDIR /app
#下载必要的Go模块
COPY go.mod ./
COPY go.sum ./
RUN go mod download
#将源代码复制到镜像中
COPY *.go ./
#在根文件系统中创建静态应用程序
RUN build -t internhw:latest .Dockerfile .
EXPOSE 8080
#当镜像用于启动容器时执行的命令
CMD ["internhw"]
当我在终端中运行docker build -t internhw:latest .Dockerfile .时，输出是：
"docker build"需要正好1个参数。
请参阅'docker build --help'。
用法：docker build [OPTIONS] PATH | URL | -
从Dockerfile构建镜像

I keep running into that error on the last line and have tried putting the dockerfile in the tmp folder but still get the same error; I even tried upper casing and lowercasing the docker file name, it didn't resolve the issue.
my file path is `Users/maheenk/Desktop/infra`
my docker file :
```sh
#syntax=docker/dockerfile:1
#using latest version
FROM golang:latest
WORKDIR /app
#Download necessary Go modules
COPY go.mod ./
COPY go.sum ./
RUN go mod download
#copies source code onto image
COPY *.go ./
#static application in rootfilesystem
RUN docker build -t internhw:latest -f .Dockerfile .
EXPOSE 8080
#command to execute when image is used to start a container
CMD [ "internhw"]
the command I run in terminal:
docker build -t internhw:latest -f .Dockerfile .
what the output is in terminal:
[+] Building 0.1s (2/2) FINISHED
=> [internal] load build definition from .Dockerfile 0.1s
=> => transferring dockerfile: 2B 0.0s
=> [internal] load .dockerignore 0.0s

-rw-r--r-- 1 maheenk staff 2126 Apr 23 16:09 main.go
I added a .Dockerfile to the folder(basically a copy of the dockerfile that i renamed by putting a period in front of)
drwxrwxr-x@ 9 maheenk staff 288 Apr 24 13:03 .
drwxrwxrwx@ 111 maheenk staff 3552 Apr 24 12:43 ..

-rw-r--r-- 1 maheenk staff 2126 Apr 23 16:09 main.go```
UPDATED VERSION:
redid the run line in docker as suggested
#syntax=docker/dockerfile:1
FROM golang:latest
WORKDIR /app
# Download necessary Go modules
COPY go.mod ./
COPY go.sum ./
RUN go mod download
#copies source code onto image
COPY *.go ./
#static application in rootfilesystem
RUN build -t internhw:latest .Dockerfile .
EXPOSE 8080
#command to execute when image is used to start a container
CMD [ "internhw" ] ```
when i run in terminal docker build -t internhw:latest .Dockerfile .
"docker build" requires exactly 1 argument.
See 'docker build --help'.

在Dockerfile中执行`docker build`确实没有太多意义，因为Dockerfile本身就是通过'docker build'构建的。
如果你需要向现有镜像添加资源，可以在你的Dockerfile中使用COPY或ADD命令。
如果你需要编译某些内容并将结果放入现有镜像中，可以使用多阶段构建。你可以参考[多阶段构建文档][1]。

It does make little sense to do a `docker build` inside a Dockerfile which is itself... 'docker built'.
If you need to add resources to an existing image, you can use COPY or ADD inside your `Dockerfile`.
If you need to compile something and put the result in an existing image, you can use a [multi-stage build][1].
