Laravel Application Self-Updater

This package provides some basic methods to implement a self updating functionality for your Laravel application.

Supported update provider:

  • GitHub
  • Gitlab
  • Gitea
  • Http-based archives

Usually you need this when distributing a self-hosted Laravel application that needs some updating mechanism without Composer.

Install

To install the latest version from the master using Composer:

$ composer require qopiku/laravel-selfupdater

Configuration

After installing the package you need to publish the configuration file via

$ php artisan vendor:publish --provider="Qopiku\Updater\UpdaterServiceProvider"

Note: Please enter correct value for vendor and repository name in your config/self-updater.php if you want to use Github as source for your updates.

Setting the currently installed version

Before starting an update, make sure to set the version installed correctly. You're responsible to set the current version installed, either in the config file or better via the env variable SELF_UPDATER_VERSION_INSTALLED.

tag-based updates

Set the installed version to one of the tags set for a release.

branch-based updates

Set the installed version to a datetime of one of the latest commits.
A valid version would be: 2020-04-19T22:35:48Z

Running artisan commands

Artisan commands can be run before or after the update process and can be configured in config/self-updater.php:

Example:

'artisan_commands' => [
    'pre_update' => [
        'updater:prepare' => [
            'class' => \App\Console\Commands\PreUpdateTasks::class,
            'params' => []
        ],
    ],
    'post_update' => [
        'postupdate:cleanup' => [
            'class' => \App\Console\Commands\PostUpdateCleanup::class,
            'params' => [
                'log' => 1,
                'reset' => false,
                // etc.
            ]
        ]
    ]
]

Configure the download path

Sometimes your web host does not allow saving files into the /tmp folder of the server. You can change the folder the application is downloaded to by setting the env var SELF_UPDATER_DOWNLOAD_PATH to something different. Just keep in mind, that the folder is not inside the folder your application lives in as it might be overwritten during the update.

Notifications via email

You need to specify a recipient email address and a recipient name to receive update available notifications. You can specify these values by adding SELF_UPDATER_MAILTO_NAME and SELF_UPDATER_MAILTO_ADDRESS to your .env file.

Config name Description
SELF_UPDATER_MAILTO_NAME Name of email recipient
SELF_UPDATER_MAILTO_ADDRESS Address of email recipient
SELF_UPDATER_MAILTO_UPDATE_AVAILABLE_SUBJECT Subject of update available email
SELF_UPDATER_MAILTO_UPDATE_SUCCEEDED_SUBJECT Subject of update succeeded email

Private repositories

Private repositories can be accessed via (Bearer) tokens. Each repository inside the config file should have a private_access_token field, where you can set the token.

ℹ Do not prefix the token with Bearer . This is done automatically.

Usage

To start an update process, i. e. in a controller, just use:

Route::get('/', function (\Qopiku\Updater\UpdaterManager $updater) {
    // Check if new version is available
    if($updater->source()->isNewVersionAvailable()) {
        // Get the current installed version
        echo $updater->source()->getVersionInstalled();

        // Get the new version available
        $versionAvailable = $updater->source()->getVersionAvailable();

        // Create a release
        $release = $updater->source()->fetch($versionAvailable);

        // Run the update process
        $updater->source()->update($release);
    } else {
        echo "No new version available.";
    }
});

Currently, the fetching of the source is a synchronous process. It is not run in background.

Using GitHub

The package comes with a GitHub source repository type to fetch releases from GitHub - basically use GitHub to pull the latest version of your software.

Just make sure you set the proper repository in your config/self-updater.php file.

Tag-based updates

This is the default. Updates will be fetched by using a tagged commit, aka release.

Branch-based updates

Select the branch that should be used via the use_branch setting inside the configuration.

// ...
'repository_types' => [
    'github' => [
        'type' => 'github',
        'repository_vendor' => env('SELF_UPDATER_REPO_VENDOR', ''),
        'repository_name' => env('SELF_UPDATER_REPO_NAME', ''),
        // ...
        'use_branch' => 'v2',
   ],
   // ...
];

Using Gitlab

Configure Gitlab either via the config/self-updater.php or use the appropriate environment variables.

// ...
'repository_types' => [
    'gitlab' => [
            'base_url'             => '',
            'type'                 => 'gitlab',
            'repository_id'        => env('SELF_UPDATER_REPO_URL', ''),
            'download_path'        => env('SELF_UPDATER_DOWNLOAD_PATH', '/tmp'),
            'private_access_token' => env('SELF_UPDATER_GITLAB_PRIVATE_ACCESS_TOKEN', ''),
   ],
   // ...
];

ℹ Although the environment variable is named SELF_UPDATER_REPO_URL, only specify your repository id.

For self-hosted Gitlab instances you can set the base_url variable to a domain where the instance is hosted at, f. ex. http://gitlab.acme.local.

Using HTTP archives

The package comes with an HTTP source repository type to fetch releases from an HTTP directory listing containing zip archives.

To run with HTTP archives, use following settings in your .env file:

Config name Value / Description
SELF_UPDATER_SOURCE http
SELF_UPDATER_REPO_URL Archive URL, e.g. http://archive.webapp/
SELF_UPDATER_PKG_FILENAME_FORMAT Zip package filename format
SELF_UPDATER_DOWNLOAD_PATH Download path on the webapp host server

The archive URL should contain nothing more than a simple directory listing with corresponding zip-Archives.

SELF_UPDATER_PKG_FILENAME_FORMAT contains the filename format for all webapp update packages. I.e. when the update packages listed on the archive URL contain names like webapp-v1.2.0.zip, webapp-v1.3.5.zip, ... then the format should be webapp-v_VERSION_. The _VERSION_ part is used as semantic versionioning variable for MAJOR.MINOR.PATCH versioning. The zip-extension is automatically added.

The target archive files must be zip archives and should contain all files on root level, not within an additional folder named like the archive itself.

Using Gitea

With Gitea you can use your own Gitea-Instance with tag-releases.

To use it, use the following settings in your .env file:

Config name Value / Description
SELF_UPDATER_SOURCE gitea
SELF_UPDATER_GITEA_URL URL of Gitea Server
SELF_UPDATER_REPO_VENDOR Repo Vendor Name
SELF_UPDATER_REPO_NAME Repo Name
SELF_UPDATER_GITEA_PRIVATE_ACCESS_TOKEN Access Token from Gitea
SELF_UPDATER_DOWNLOAD_PATH Download path on the webapp host server
