Sure, shouldn’t be anything too tricky but I have to guess on a few things.
Build It:
cd ~/path/to/codebase
docker build -t mycoolimage:latest .
Run It:
docker run --rm -it -p 8080:8080 mycoolimage:latest
# Then head to http://localhost:8080 in your browser
I’m assuming port 8080 is listening for connections in the container. In other words, whatever is running in the container - your app - is setup to listen for HTTP connections on port 8080 - it might not be!
If you want to share your Dockerfile and fly.toml (redact anything sensitive) - that will help.
