英文:
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:latestWORKDIR /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=> => transferring context: 2B 0.0sfailed 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：

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 160drwxrwxr-x@ 9 maheenk staff 288 Apr 24 13:03 .drwxrwxrwx@ 111 maheenk staff 3552 Apr 24 12:43 ..-rw-r--r--@ 1 maheenk staff 6148 Apr 24 13:03 .DS_Store-rw-r--r--@ 1 maheenk staff 513 Apr 24 13:06 .Dockerfiledrwxr-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:1FROM golang:latestWORKDIR /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<details><summary>英文:</summary>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 versionFROM golang:latestWORKDIR /app#Download necessary Go modulesCOPY go.mod ./COPY go.sum ./RUN go mod download#copies source code onto imageCOPY *.go ./#static application in rootfilesystemRUN docker build -t internhw:latest -f .Dockerfile .EXPOSE 8080#command to execute when image is used to start a containerCMD [ "internhw"]

I added a .Dockerfile to the folder(basically a copy of the dockerfile that i renamed by putting a period in front of)

UPDATED VERSION:
redid the run line in docker as suggested
#syntax=docker/dockerfile:1FROM golang:latestWORKDIR /app# Download necessary Go modulesCOPY go.mod ./COPY go.sum ./RUN go mod download#copies source code onto imageCOPY *.go ./#static application in rootfilesystemRUN build -t internhw:latest .Dockerfile .EXPOSE 8080#command to execute when image is used to start a containerCMD [ "internhw" ] ```
when i run in terminal docker build -t internhw:latest .Dockerfile .
"docker build" requires exactly 1 argument.See 'docker build --help'.Usage: docker build [OPTIONS] PATH | URL | -Build an image from a Dockerfile</details># 答案1**得分**: 1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]。[1]: https://docs.docker.com/develop/develop-images/multistage-build/<details><summary>英文:</summary>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].[1]: https://docs.docker.com/develop/develop-images/multistage-build/</details>
