如何在Docker容器上运行Golang Web应用

Question

I have a web app that uses go language as it's back end. When I run my website I just do go build; ./projectName then it will run on local server port 8000. How do I run this web app on a container? I can run sample images like nginx on a container, but how do I create my own images for my projects. I created a Dockerfile inside my project folder with the following codes:

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)

Answer 1

I guess you are not exposing the Docker Port outside the container. That's why you are not able to see any output rather than just being specific to GO Program. Try adding the below lines to your docker compose File

EXPOSE 80(whichever port you want it to be)
EXPOSE 443
EXPOSE 3306

This will make the container be accessed from outside
