Goal

Allow a consultant to access the source-code of a specific project for a limited time.

Background

Many consultants are hardware gurus or software gurus, but don't necessarily have proficiency with Linux, git, etc.

Pre-Requisites

• Ubunut Server 9.04+
• gitosis (see previous article)

Informing the consultant

Tom,

I'm giving you access to our codebase directly so that you can make changes and we can get frequent updates and review the changes (and see the comments).

I need you to e-mail me your public ssh key in order to give you access. You can find that in ~/.ssh/id_rsa.pub (or create it using ssh-keygen).

Alternatively, you can place the attached id_rsa in ~/.ssh/ and start right away.

Once we have the ssh keys you can access the repository like so:

sudo apt-get install git-core
cd ~/
git clone ssh://gitosis@git.example.com:22/project-name.git

That will create the project-name folder in your home directory.

Once you make changes you will need to need to add, commit, and then push them back to us.

git stat
git add file1 file2 file3
git commit -m "some helpful message"
git push origin master

You can make as many commits before the push as you'd like. The comments will help us as we look it over and test against it.

Thanks for you help on the project!

Authorizing the consultant

Create a new private/public key pair from a guest-ish account and e-mail the pair to the consultant

ssh-keygen
cp ~/.ssh/id_rsa.pub /tmp/

Add the consultant to gitosis

git clone ssh://gitosis@git.example.com:22/gitosis-admin.git
cd gitosis-admin
KEY=/tmp/id_rsa.pub
KEYNAME=`cat ${KEY} | cut -d'=' -f3 | cut -d' ' -f2`
echo ${KEYNAME}
mv ${KEY} keydir/${KEYNAME}.pub
vim gitosis.conf

Add the consultant to the particular projects

[group project-name-team]
writable = project-module-1 project-module-2
members = keyname-existing-1 keyname-existing-2 consultant-new-1

Then commit the change and the consultant has access

git add gitosis.conf keydir
git commit -m "added tom as consultant on project-name"
git push origin master

Mark your calendar to delete this key after the contract period.
