Bare and Non bare repository
Git is a very powerful version control system to maintain our code. We can share and keep history of our code so effectively.
We have a remote repository which is actually called
bare repository and the local one called
non bare repository.
So Git bare repository is a shared repository where we push our code.
It does not have files and directories like
non bare repository and not even
.git so its not for development or to work on.
And also you cannot run
git status/pull/push/fetch commands in bare repository.
A remote repository should always be a bare repository.
You can clone your remote repository with
git clone --bare [your remote repositry url]
Here you will see that there are no files and directories as we have in our development or working repository.
Lets try it out on your local system.
Create a Git bare repository
mkdir test_bare cd test_bare_repo git init --bare
When we do
ls -lart you will see something like
Now create a non bare repository and add bare repository as origin
mkdir test_non_bare cd test_non_bare git init git remote add origin /Users/raysrashmi/crap/test_bare_repo [path of bare repo created above]
Or you can clone bare repository
git clone /Users/raysrashmi/crap/test_bare_repo test_non_bare
Now add README file here
touch README git push origin master
As you see we can write code here and push to remote repository which is bare.
Now clone your development repository 'test_non_bare'
mkdir git clone /Users/raysrashmi/crap/test_non_bare test_clone cd test_clone
If we update README file, commit and then try to push we can't because we are pushing to non bare repository.
Migrating a Git repository
Sometime we require to migrate our Git repository to another location. we have to use
Run following commands for migrating repository
git clone --bare email@example.com:username/old-repo.git cd old-repo.git git push --mirror firstname.lastname@example.org:username/new-repo.git
Mirroring from bare repository will keep all you history every brach and tag of you remote repository. and will not push any local branch or changes to new repository
