selecting an AMI for deploying a haskell app?

Question

I'm working on a haskell web app using yesod that I eventually want to deploy to EC2, can someone recommend an AMI that has a recent haskell platform and a git client install-able from the repositories?

Answer 1

If you look at Michael Snoyman's setup script here, it contains the steps he used to get an EC2 instance going on a Ubuntu AMI.

https://github.com/yesodweb/benchmarks/blob/master/setup.sh

I also have Yesod running from source on Amazon Linux. It takes a few hours to build everything but I think any of the standard boxes with at least 8G of memory should do it (otherwise GHC can't link). This is how I did it:

# install what packages are available
sudo yum --enablerepo=epel install haskell-platform git make ncurses-devel patch

# make and install ghc
wget http://www.haskell.org/ghc/dist/7.0.4/ghc-7.0.4-src.tar.bz2
tar jxf ghc-7.0.4-src.tar.bz2
rm ghc-7.0.4-src.tar.bz2
cd ghc-7.0.4
./configure
make -j 4
# wait a few hours
sudo make install
cd
rm -rf ghc-7.0.4

# make and install haskell-platform
wget http://lambda.haskell.org/platform/download/2011.4.0.0/haskell-platform-2011.4.0.0.tar.gz
tar zxf haskell-platform-2011.4.0.0.tar.gz
cd haskell-platform-2011.4.0.0
./configure
make -j 4
sudo make install
cd
rm -rf haskell-platform-2011.4.0.0

Answer 2

You shouldn't compile on an EC2 instance. Choose a generic AMI like Ubuntu, and perform the compile on a local computer, then upload the static binary to EC2.
