No handler accepted "/"

I’m trying to make ekg accessible out in the open on a server using

forkServer anIpAddress aPort

when visiting that ip address on that port I get No handler accepted "/". Is this expected? If so, how do I use ekg remotely?

It might be better to use fileEmbed so that directories don’t need to be found.

Here’s my story while running into this problem:

I’m using Stack to build a web app (including ekg) that I’m deploying inside a Docker container. In particular, I’m installing my app in a fresh container with no explicit Haskell dependencies (we’ll see how that goes!). JSON API calls to EKG worked but HTML did not.

The problem was indeed that the directory of assets didn’t exist in the runtime container, and ekg could not find it. This directory contains the files needed to provide the HTML interface, and Snap apparently raises this error when a file it’s trying to serve can’t be found (see https://github.com/snapframework/snap/issues/102 ).

The problem Sean mentions in https://github.com/tibbe/ekg/issues/48 bit me hard, since if his path to the assets directory was weird, mine using Stack/Docker is really weird. I don’t know an easy way to magic these files into my Docker installation, so I cheated: I’m pinning the ekg version for now and copying the assets/ directory into my project.

One final note: You’ll see that ekg appends </> assets to your data directory, so make sure you’re not setting your data directory to the assets directory itself! I installed my stuff in /app/ekg-0.4.0.9/assets, and set ENV ekg_datadir=/app/ekg-0.4.0.9 in my Docker container. That was what did the trick.
