Docker如何在ngnix中使用dockerfile构建映像？

问题描述

我想构建映像，并且已经构建了Dockerfile。我已经有了容器，但是该映像对我来说很难，这是Dockerfile的代码：

FROM nginx:alpine
COPY . /usr/share/nginx/html

但是问题是，我试图使用此命令在终端（我正在使用MacBook Terminal）上运行它。这段代码是我在终端中写的：

Build an image from a Dockerfile
tiadem_tatie@SIT-SMBP1606 ~ % docker run -p 80:80 countly_new
Unable to find image 'countly_new:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers).
See 'docker run --help'.
tiadem_tatie@SIT-SMBP1606 ~ % docker build -t Countly_new .

tiadem_tatie@SIT-SMBP1606 ~ % docker build -t countlynew path

tiadem_tatie@SIT-SMBP1606 ~ % docker build -t image-name path

tiadem_tatie@SIT-SMBP1606 ~ % docker build -t image-name path
unable to prepare context: path "path" not found
tiadem_tatie@SIT-SMBP1606 ~ % docker run --help

文档Dockerfile在我的下载文件夹中。我可以在那里有命令吗，如果可以的话，我需要有关如何构建mongoDB和Backend的帮助。然后，我想将两者连接在一起。 谢谢你

解决方法

为什么要将项目文件保存在Downloads文件夹中？这听起来像一个可怕的主意。

仍然，假设您的Dockerfile和网站文件都位于该位置，请运行以下命令来构建映像：

docker build -t countly_new:latest ~/Downloads
