Automatic deployment using Travis CI

Tired of deploying manually with couscous deploy? You can set up Travis so that it will deploy automatically for you on each push to master.

To set this up, please follow all the steps below.

1. Create a GitHub token

In order to push to your repository from Travis, you need to authorize Travis. You do so by creating a GitHub token and then encrypting it to store it in .travis.yml.

from your GitHub account, go in Settings > Personal access tokens
create a new Personal Access Token and give it the public_repo permission (if the repository is public)
install the Travis command line tool

gem install travis
run travis login in the repository directory
encrypt the token:

travis encrypt GH_TOKEN=YOUR_TOKEN_HERE --add

The --add flag will automatically write the encrypted string to your .travis.yml file.

your .travis.yml should now contain a new secure line looking like this:

env:
  global:
    - secure: aeuwi73FIpzkIuk0XkbxiYb5M+HzTIKJy/eiBa5gWhSWq6FlI1fysDGvDcExnKyNH0z9sud0sNPBbi5O5z/uiqupoxoBLuFHfLG3NnLrvjQ2SAmrsIBWtsU737Vo5klbfJp2oJ0hrQCIlczwkfK5j+HbQmGUoS5w81pr3kPxnst=

2. Install Couscous

Couscous must be installed to be used in Travis. If you have been using the Phar, you should install Couscous using Composer instead:

$ composer require couscous/couscous

This will update your composer.json.

3. Update `.travis.yml`

Here is an example of what your .travis.yml might look like. This assumes you use Travis to run PHPUnit tests. If not, look at the next section.

language: php
php:
  - 7.3
env:
  global:
    - GIT_NAME: "'Couscous auto deploy'"
    - GIT_EMAIL: couscous@couscous.io
    - GH_REF: github.com/CouscousPHP/Couscous
    - secure: ...
before_script:
  - composer install --no-progress
script:
  - phpunit
after_success:
  - vendor/bin/couscous travis-auto-deploy

As you can see above, you need to set up:

GIT_NAME and GIT_EMAIL
GH_REF is the GitHUb repository URL
composer install is necessary to install Couscous
vendor/bin/couscous travis-auto-deploy

Without PHPUnit

If you use Travis only to update the website, then use script: instead of after_success:

language: php
php:
  - 5.4
env:
  ...
before_script:
  - composer install --no-progress
script:
  - vendor/bin/couscous travis-auto-deploy

Options

If you run your tests against multiple PHP versions, you want to deploy the website only once (i.e. not for all PHP versions). To do this, travis-auto-deploy will deploy only when the PHP version is 5.4.

You can customize this using the --php-version option:

language: php
php:
  - 5.5
...
after_success:
  - vendor/bin/couscous travis-auto-deploy --php-version=5.5
