In your favorite text editor create a file called Dockerfile in the same directory you used in step 1. No extension, just Dockerfile. Paste in this code and save the file:
This tells Docker to use the same nginx base image, and create a layer that adds in the HTML you created in the last step. Instead of creating a volume that accesses the file directly from the host you are running on, it adds the file to the image. To build the image, in your terminal, type:
Two things, first replace <YourDockerID> with your Docker ID. Also notice the “.” at the end of the line. That tells Docker to build in the context of this directory. So when it looks to COPY the file to /usr/share/nginx/html it will use the file from this directory.
You can run it:
And go to http://localhost:8080 to see the page.
Next login to Docker Hub. You can do this directly from Docker Desktop. Or you can do it from the command line by typing.
