* git-lfs: The url provided to initremote/enableremote will now be stored in the git-annex branch, allowing enableremote to be used without an url. initremote --sameas can be used to add additional urls. * git-lfs: When there's a git remote with an url that's known to be used for git-lfs, automatically enable the special remote.

git-annex can store data in [git-lfs](https://git-lfs.github.com/)
|
|
repositories, using the [[git-lfs special remote|special_remotes/git-lfs]].
|
|
|
|
You do not need the git-lfs program installed to use it, just a recent
|
|
enough version of git-annex.
|
|
|
|
## getting started
|
|
|
|
Here's how to initialize a git-lfs special remote on Github.
|
|
|
|
git annex initremote lfs type=git-lfs encryption=none url=https://github.com/yourname/yourrepo
|
|
|
|
In this example, the remote will not be encrypted, so anyone who can access
|
|
it can see its contents. It is possible to encrypt everything stored in a
|
|
git-lfs remote, see [[fully_encrypted_git_repositories_with_gcrypt]].
|
|
|
|
Once the git-lfs remote is set up, git-annex can store and retrieve
|
|
content in the usual ways:
|
|
|
|
git annex copy * --to lfs
|
|
git annex get --from lfs
|
|
|
|
But, git-annex **cannot delete anything** from a git-lfs special remote,
|
|
because the protocol does not support deletion.
|
|
|
|
A git-lfs special remote also functions as a regular git remote. You can
|
|
use things like `git push` and `git pull` with it.
|
|
|
|
## enabling existing git-lfs special remotes
|
|
|
|
There are two different ways to enable a git-lfs special
|
|
remote in another clone of the repository.
|
|
|
|
Of course, you can use `git annex enableremote` to enable a git-lfs special
|
|
remote, the same as you would enable any other special remote.
|
|
Eg, for the "lfs" remote initialized above:
|
|
|
|
git annex enableremote lfs
|
|
|
|
But perhaps more simply, if git-annex sees a git remote that matches
|
|
the url that was provided to initremote earlier, it will *automatically*
|
|
enable that git remote as a git-lfs special remote.
|
|
|
|
So you can just git clone from the url, and the "origin" remote will be
|
|
automatically used as a git-lfs special remote.
|
|
|
|
git clone https://github.com/yourname/yourrepo
|
|
cd yourrepo
|
|
git-annex get --from origin
|
|
|
|
Nice and simple, and much the same as git-annex handles its regular
|
|
remotes.
|
|
|
|
(Note that git-annex versions 7.20191115 and older didn't remember the url
|
|
privided to initremote, so you'll need to pass the url= parameter
|
|
to enableremote in that case. Newer versions of git-annex will then
|
|
remember the url.)
|
|
|
|
## multiple urls
|
|
|
|
Often there are multiple urls that can access the same git repository.
|
|
You can set up git-lfs remotes for each url. For example,
|
|
to add a remote accessing the github repository over ssh:
|
|
|
|
git annex initremote lfs-http --sameas=lfs url=git@github.com:yourname/yourrepo.git
|
|
|
|
The `--sameas` parameter tells git-annex that this is the same as the "lfs"
|
|
repository, so it will understand that anything it stores in one remote can
|
|
be accessed also with the other remote.
