Hello Nginx#

First, let's remove all container.

docker rm -v -f $(docker ps -qa)

Second, run a nginx image, forward to port 8080 on local machine, and mount a volume.

docker run --name web -p 8080:80  -v ./html/:/usr/share/nginx/html:ro -d public.ecr.aws/nginx/nginx:1.27-alpine3.19-slim

Third, let's exec in to a running container.

docker exec -it web /bin/sh

And check the web server is running on port 80.

wget -O- http://localhost

Finally, in vscode forward port 8080 and open browser on port 8080 to see the index.html.
