How to use Git with a Divio application

Your Divio application is a Git repository, offering several advantages to the developer - fine-grained revision control, excellent collaboration options, easy export and replication.

We provide Git hosting by default. Our server is You can also use an external Git provider.

By default, we use the branch develop, but you can specify the Git branches to be used by each environment.

You will need to set up your public key on our Control Panel if you use our Git server.

Important limitations

Git repository contents

Certain conditions can cause deployment errors when the Control Panel tries to read the Git repository. These will typically appear in the deployment log with an exception from pygit2, such as:

Traceback (most recent call last):
File "/usr/local/lib/python3.6/site-packages/pygit2/", line 131, in __getitem__
raise KeyError(key)
KeyError: abaddeed2d00ad47a9bb82db969707a21dead81ed

This can be caused by:

  • an empty directory committed to the repository (remove it or add a file to it)
  • a Git submodule included in the repository (remove it)
  • files containing mixed line endings, if the .gitattributes configuration includes an instruction to resolve them (remove * text=auto if it appears in .gitattributes).

Git repository size

We don't impose limits on the size of your application's Git repository. However, as its size increases, both our infrastructure and Git itself have to work harder to manage it.

Above 100MB for its Git repository, we cannot guarantee that an application will function smoothly, especially when our platform is under heavy load. It can cause:

  • slower deployments
  • deployment timeouts
  • long backup times

If your application's Git repository, including its history, exceeds 800 MB you are likely to run into persistent deployment problems.

If you need to store large amounts of data, use the application's media storage rather than Git.

Basic Git operations

It's beyond the scope of this documentation to provide a guide to Git, but to get you started, the basic operations you will need are described here.

Push your changes to the Cloud

If you have made some local changes and want to push (i.e. upload) them to the Cloud, the basic steps you need are:

  • git status to see the changed files
  • git add <file1> <file2> (etc) to stage the changes (alternatively, you can do git add . to stage everything)
  • git status to make sure everything has been staged
  • git commit -m "<your commit message>" to commit the changes (provide a meaningful message for your own benefit)
  • git push origin develop to push your local changes to the origin (i.e. our server)

Pull changes from the Cloud

  • git pull will pull fetch and merge any changes that have been made on the Cloud
