LFS via ssh

[Rudy Holtkamp]

Hi there,

For security reasons we have disabled https cloning from our Bitbucket instance. (Admin > Server Settings > HTTP(S) SCM hosting > HTTP(S) enabled > off)

Is it possible to use LFS via ssh? And if so, how can we do this?

Regards

Rudy

This is not currently possible - the git-lfs extension is built around HTTP.

Reference:

The Git LFS client uses an HTTPS server to coordinate fetching and storing large binary objects separately from a Git server.

(from https://github.com/git-lfs/git-lfs/tree/master/docs/api)

Sorry I was not completely clear, we use Bitbucket server, not Cloud.

I'm getting the following error message:

>git push
Git LFS: (0 of 1 files) 0 B / 128.45 KB
batch response: Unable to parse HTTP response for POST https://mybitbucket/scm/project/test-lfs.git/info/lfs/objects/batch: invalid character '\n' in string literal
error: failed to push some refs to 'ssh://git@mybitbucket:7999/project/test-lfs.git'

When I enable https on the server, it does work. But for security reasons we may only interact with git with ssh

Please check the git remote url. Is it pointing to HTTPS?

I clone with ssh, so no my remote is pointing to ssh.

Here are my settings:

>git remote -vv
origin ssh://git@mybitbucket:7999/project/test-lfs.git (fetch)
origin ssh://git@mybitbucket:7999/project/test-lfs.git (push)

>git lfs env

The Git LFS  uses HTTP Basic Authentication to authorize requests.

Hi Rudy,

Yes, it is possible. After SSH keys have been setup.

git clone git@bitbucket.org:test/repo.git

git lfs clone git@bitbucket.org:test/repo.git

Correct. For anyone looking at this for information, git lfs does now support authentication over ssh.
