Deployer 7+ functionality used by Unleashed Technologies

0.5.0 2022-10-25 18:14 UTC


Latest Version Software License Build Status

This package uses Deployer 7, which supports recipes defined by YAML or PHP.

Deployer will import the recipes in a linear fashion. Placeholders will be replaced with actual values as late as possible. Deployer looks for deploy.php or deploy.yaml when run.


All recipe paths have been adjusted to use the files in the vendor directory and thus should be installed with composer:

composer require unleashedtech/deployer-recipes


Recipes have been organized to easily support any version of any software. They make several assumptions about git repository settings, deployment locations & host settings. These assumed default values are only applied if you haven't already defined them. Please choose a platform below for more.

Please note that tasks assume databases on relevant stages have already been configured. If you need to skip all database operations, you can set skip_db_ops to true via the command line.

Run vendor/bin/deployer.phar tree deploy to view the deploy recipe tree.

Run vendor/bin/deployer.phar deploy to deploy.

Run vendor/bin/deployer.phar to review available recipes.

Before/After Hooks

Deployer supports running tasks before or after other defined tasks. Defining custom tasks to trigger before & after other defined tasks is trivial. Such functionality can be added to the end of deploy.yaml, as shown below:

            - "echo 'foo'"
            - "echo 'bar'"

    deploy:symlink: foo

    deploy:unlock: bar

SSH Hosts

This package will dynamically define hosts based on global configuration values. It loops over a CSV list of environments in the environments variable, defining 0 or more hosts for each environment. By default, production, staging & dev environments are defined. For each environment, the package defines a number of hosts based on the integer value of the matching {environment}_webservers variable (e.g. two hosts defined for production based on the production_webservers variable value). These hosts will be linked together by their environment name (or stage, in Deployer parlance). When you want to deploy to production, you would probably run a command similar to dep deploy stage=production. This package assumes there are 2 production webservers, by default.

    production_domain: "production1.example"
    production_webservers: 3

Configuring SSH

The hosts defined by Deployer are merely aliases. During execution, Deployer will assume hosts defined internally are available via SSH. You can add hosts to your ~/.ssh/config file, or you can add Include directive(s) which will load config provided by other files into your main SSH config. Such definitions can occur immediately before an automated deployment.

Each project can provide its own SSH config. Consider creating an .ssh folder in your project root & creating a config file within.

You can manually include config for specific projects:

Include ~/projects/foo/.ssh/config

You can also use a pattern to auto-include project config from many folders:

Include ~/projects/*/.ssh/config
