New subject: Deploy Haskell application

11 Jun 2014


      Hi,
it seems that 'cabal configure' fails if some dependencies are missing.
Then cabal copy complains that I should run 'cabal configure' first...

Hi Corentin,
I think you're searching for `cabal configure && cabal copy`. It will
still have an exit code of 1 if you don't compile anything but it will copy
the files from data-files (and alike).
On my machine, it copies share/index.html into
.cabal-sandbox/share/x86_64-openbsd-ghc-7.6.3/dummy-0.1.0.0/share/index.html.

In the .cabal file you can put a directive "data-files" and they will be
deployed in ~/.cabal/share...
I want to trigger only this.

Not sure what you mean - cabal doesn't do any deployment, or at least I
have not found a useful way of making it do so. In our case the deployment
is done by running apt-get update && apt-get install on the server.

Thanks for your response!
Is there a way to ask Cabal to just deploy the resources and not
compile everything?

We package up the executables and other files into a Debain .deb
package using fpm after running cabal. Here is an example Makefile which
runs cabal, creates the debian package and adds it to our apt server:
https://github.com/openbrainsrc/debcd/blob/master/Makefile
This is run by our CI server after every commit to GitHub.

Hi,
These days, an increasingly popular solution to package an application
with its dependencies is to use Docker. You can build the Docker image
locally and push it to a Docker registry and retrieve it on your
remote machine, or you can dump it as a tarball and load it on your
remote machine.
You have different ways to create the Docker image, one of which would
be similar to pushing your Haskell binary to your remote machine. That
way is simply to compile your exectuable locally, and copy it to the
remote machine with is assets if any (you might even move it to a
.cabal directory as if it was installed through `cabal install`). By
default your executable will be statically linked, except for libgmp
that you have to install on the remote machine.
I recommand you look into Docker. You will be able to e-use its
knowledge to package increasingly complex applications (that might
have more numerous dependencies that you wouldn't have to manage on
the host).
