如何在Docker容器上运行Golang Web应用

go build; ./projectName

FROM nginx:latest

WORKDIR static/html/

COPY . /usr/src/app

Then made an image using the Dockerfile, but when I run it on a container and go to localhost:myPort/static/html/page.html it says 404 page not found. My other question is, does docker can only run static pages on a container? cause my site can receive and send data. Thanks

this is my docker file (./todo is my project name and folder name)

this is my terminal ( as you can see the the container exits emmediately)
