As a system administrator I would like to be able to write an automated process for installation to a production server that:
- has access to a remote git repository (say on
git.mycompany.com
) - can get a copy of one branch/label (say
release_20110721_01
) from the repository - will not create a local copy of the entire repository
In other words, have a central repository containing all the revisions, but then install to production servers the specific tag only.
Is there a way of doing this? At least with CVS a working copy of a module with a given tag can be obtained without having to pull a copy of the entire repository.
That is the main difference between a centralised VCS (like CVS) and a DVCS (Distributed): you always clone all the content of a repo, even though you can perform a shallow clone, as Olipro mentions.
Doing a shallow clone of just one branch is possible, but complicated: See "Partial clone with Git and Mercurial".
But I recommend not using Git as a release management / deployment tool: "How to shallow clone a single branch in git?".
I would rather go with
git archive
to zip the right branch/version you need, and then copy that to the appropriate server.sure, make your central repository accessible to the unprovisioned production server, perform a git clone from the server using the
-b
and--depth
options to specify which branch you'd like along with the revision depth you want the server to have available to it.
