git-deploy ↑

Description ↑

git-deploy is a deployment tool to allow for quick and easy deployments based on the changes in a git repository.

It was originally used to update multiple WordPress installations on shared hosting environments. Ideally Capistrano would have been the perfect tool, but generally shared hosting environments only allow for FTP access, which Capistrano does not support. Likewise rather than using a standard FTP program, when doing a deployment, I only need to upload the files that have been changed. This saves me both time and bandwidth.

I needed something like Capistrano, but simpler.

git-deploy supports deployment over SSH and FTP.

Installation ↑

git-deploy requires the Ruby gems net-ssh, net-sftp, net-scp.

You can install them like so:

sudo gem install net-ssh net-sftp net-scp

Usage ↑

In the root directory of your source code, create a deploy.yml file.

Here is a sample code:

'settings':
  ignore_if_same_revision: true

'ftp://example:[email protected]:21/path/to/installation':
  skip: false

You use the URI scheme to define the location of your installation. If you do not want to use the URI scheme, and instead use another identifier. Feel free to do so. Just enter the settings for the host like so:

'example':
  skip: false
  scheme: ftp
  user: example
  password: password
  host: example.com
  port: 21
  path: /path/to/installation

Note: The port field is optional in both the URI scheme and the broken down options

Once you have done creating the deploy.yml, upload to your server a file called REVISION with the revision string for the current revision residing on the server

After you have commited your code to the repository. You can run

git deploy

You will also need to upload a REVISION file to your server inside the installation path, ie “/path/to/installation”

To create a REVISION file for HEAD, exexcute:

git rev-parse HEAD > REVISION

This will create a REVISION file which you will need to upload to your server

Additional Keys ↑

The configuration for a site has additional and optional options:

  • skip: true or false (default). Whether to skip the configuration

  • debug_mode: true or false (default). For FTP only. Outputs debugging information

  • passive: true or false (default). For FTP only. Enable passive connection.

  • local_path: string. Only consider files to upload in a particular local path.

How It Works ↑

git-deploy stores file called REVISION on your server inside the root path to your application. This file stores the current revision of your application residing on your server.

When you run a git deploy, git-deploy downloads the REVISION file, and checks to see what files are different between revisions and either upload the changed files or deletes them from the server.

TODO ↑

  • Create a Ruby gem for the script. Sadly gem-deploy was taken.
