Containerzied React 应用程序和 NGINX 不在我想要的本地主机端口上提供服务

Question

I have a containerized React app that I'm trying to test out building with webpack and serving the static generated files with the NGINX image, but it's not being displayed on the port I want locally. My WebPack file is outputting files in to a directory called dist so as you can see in my Dockerfile I'm going in to that directory and copying my files to the usr/share/nginx/html directory. Is there something else I'm missing in this file?

Nginx 在端口 80 上提供服务，因此当您运行容器时，您需要在docker run命令中将该端口映射到端口 3000：

docker run -d -p 3000:80 app-image
