Tooling and scripts for git push based deployment at 4teamwork.

Project description


ftw.deploy provides opinionated tooling for git-push based deployment setups. The tool helps installing hooks and deployment scripts.


ftw.deploy simply provides a deploy command as console script. It requires Python 3!

The package can be installed with pip in combination with your favorite way of isolation / virtual-env.


$ python3 -m venv ftw.deploy
$ cd ftw.deploy
$ source bin/activate
$ ./bin/pip install ftw.deploy

# sym-link the deploy script into your PATH
$ ln -s `pwd`/bin/deploy ~/bin
$ deploy --help


After installation, should have a deploy command available. The most recent documentation is available with deploy help.

Initialize deploy scripts

The first step in a fresh project is to initialize the deployment scripts. This can be done with deploy init plone. This will create scripts in the folders deploy and scripts.

Installing deployment and configuring the remote

Next, install the deployment on the server by cloning the repository and performing installation steps. Then adapt scripts/setup-git-remotes with the deployment location and execute it.

Setup hook

For installing the post-receive hook and configuring the repository execute the deploy setup [remote] command.

Update scripts

You can update existing scripts in a project with deploy update.

Installing an update

When all is set up, you can simply push on the master-branch of the remote in order to install an update. Examples:

git push prod master
git push test my-branch:master
git push prod test/master:master

Rerun a deployment

If you need to rerun a deployment, simply use deploy rerun [remote].

Connect to the deployment with ssh

ftw.deploy provides a shortcut for connecting with ssh and cd’ing into the deployment directory deploy ssh [remote].



The plone template contains push deployment scripts which are optimized for use in combination with ftw.buildouts.

Custom update script

The deploy/after_push script can be configured to run another script than deploy/update_plone.

For example you could add a scripts/nightly-reinstall and then add to your nightly buildout configuration file:

deployment-update-plone-script = scripts/nightly-reinstall

Be aware that this must be in the buildout.cfg of the deployment (which may be a symlink), but it can not be extended since the buildout config file is not parsed recursively for this option.

Advanced Usage

VPN without SSH

When the deployment is in a VPN without SSH access, we cannot push to the deployment. In this situation the deploy/pull script can be used for simulating a push. It pulls from the upstream (the branch must have an upstream defined) and runs the deployment scripts.

Zero Downtime

When upgrades need to be installed, the script normally takes the site offline in order to prevent conflicting writes to the database while the upgrades run.

When having a zero downtime environment, such as when only a publihser writes the database (which is stopped while running upgrades), it is safe to keep the site running for anonymous users.

In order to enable this behavior you must set the deployment-zero-downtime option in the buildout configurations which should be upgraded in zero downtime mode.

WARNING: The deployment-zero-downtime must be in the buildout.cfg file of the deployment. It does not work when using extend for this option since the option is directly read from buildout.cfg.


extends =

deployment-zero-downtime = true

Deploy one commit with zero downtime

When deploying a commit with upgrade steps, the site will be taken offline unless zero downtime is configured. But sometimes we want to deploy a commit with (fast) upgrades to a non-zero-downtime deployment, but without downtime. For marking a commit as “zero-downtime proof”, you can push it to the branch zero-downtime on the deployment remote, before doing a regular deployment.

$ git push testing master:zero-downtime
$ git push testing master

Activate zero downtime by environment variable

When using deploy/pull, we can activate the zero downtime strategy with an environment variable:


$ ZERO_DOWNTIME=true deploy/pull


In order to develop ftw.deploy, you need to install pipenv and follow these instructions:

$ git clone
$ cd ftw.deploy
$ pipenv install --dev
$ pipenv shell
$ deploy --help
$ pytest
