Re: [Haskell-cafe] Deploying Scotty App to AWS

Update: I found out that it works when I use normal scotty, but not when I use scottyTLS. When I use scottyTLS, it prints "starting up", but doesn't get to "getting here". No error messages

Really shooting in the dark here... but could it be a lack of entropy? crypto-random (which scotty-tls depends on) seems to favor /dev/random [1], which can block. Chris [1] http://hackage.haskell.org/package/crypto-random-0.0.8/docs/src/Crypto-Rando...

@Konstantine: Just learned how to do Docker - very cool! Here's my image - it's an ubuntu 14.04. https://registry.hub.docker.com/u/sportanova/starme/

To run, do these commands:

source /root/.profile

/starme/StarMe/dist/dist-sandbox-2c59b82/build/starz/starz "test.key" "test.cert"

@Brandon: I tried running sudo strace <executable>, but I got the error:

trace: test_ptrace_setoptions_followfork: PTRACE_TRACEME doesn't work: Permission denied

strace: test_ptrace_setoptions_followfork: unexpected exit status 1

Thanks Konstantine + Brandon!

Also, just for making this super-clear to reproduce, I would advice to express a problem as a Dockerfile that lets you reproduce the problem in a one command.

Thanks.

I'm having trouble running my Scotty binary on amazon web services...

I'm using Ubuntu 15.04, this gist (https://gist.github.com/yantonov/10083524) to install the haskell platform dependencies, and then I do a git pull to my repo and build my binary.

Everything compiles, but when I do ./cabal-sandbox/bin/app or

./dist/build/app/app, nothing happens. No error messages or anything - the terminal just goes to the next line and hangs (on my Mac development machine the server starts up fine and prints a startup message).

Any ideas or experience with deploying Scotty / Haskell apps would be really appreciated, thanks!
