#17 how to access git projects?

[Lee Worden]

I tried uploading some code to github and pointing PE at it using a pe-git: uri, but it didn't work because I would have to set up a keypair for the apache user and I'm wary. So then I cloned the repo to a directory in my home directory - first of all pe-git:/home/wonder/net-dyn-github doesn't work - I think it tries to use /home/wonder/.git - then pe-git:/home/wonder/net-dyn-github/ looks for the right thing but can't access it - because apache can't execute /home/wonder?
Finally I moved it to pe-git:/usr/local/src/net-dyn-github/ and this seems to work.

I need to clarify what are workable ways to access external repositories.

ok, I got this working now, by doing the following:

wonder$ sudo -u apache -i
apache$ ssh-keygen -t rsa -C "projectengine"  # create an RSA keypair for SSH to use
# save the keypair as ~/.ssh/projectengine_rsa, not the default id_rsa.
# this is so it won't be used by default if ever ssh is invoked as apache, only for github.
apache$ ssh-keygen -p
# set the projectengine keypair to have no passphrase

# now go onto http://github.com, create an account for "projectengine-at-yushan-mcmaster-ca"
# and associate the public key in projectengine_rsa.pub with this account
# I gave it an email address connected to my gmail account, and an easy password which I will
# record at the lab wiki, just in case.

apache$ vi ~/.ssh/config # and enter the following lines:
Host *github.com
IdentityFile ~/.ssh/projectengine_rsa

# this tells it to use the projectengine keypair only when contacting sites in the github.com domain.

apache$ ssh git@github.com # test that it recognizes us

# now copy apache's .ssh/ directory to all the cluster nodes.

# this actually works!  PE is able to pull directly from pe-git:git@github.com:worden-lee/net-dyn.git
# into a project directory.
# I hope it isn't a terrible security flaw.

I have now done this for lalashan as well. Details are on the main page of the lab wiki.
