Handling private packages with Satis

Satis can be used to host the metadata of your company's private packages, or your own. It basically acts as a micro-packagist. You can get it from GitHub or install via CLI: composer.phar create-project composer/satis.

Setup

For example let's assume you have a few packages you want to reuse across your company but don't really want to open-source. You would first define a Satis configuration file, which is basically a stripped-down version of a composer.json file. It contains a few repositories, and then you use the require key to say which packages it should dump in the static repository it creates, or use require-all to select all of them.

Here is an example configuration, you see that it holds a few VCS repositories, but those could be any types of repositories. Then it uses "require-all": true which selects all versions of all packages in the repositories you defined.

{
    "repositories": [
        { "type": "vcs", "url": "http://github.com/mycompany/privaterepo" },
        { "type": "vcs", "url": "http://svn.example.org/private/repo" },
        { "type": "vcs", "url": "http://github.com/mycompany/privaterepo2" }
    ],
    "require-all": true
}

If you want to cherry pick which packages you want, you can list all the packages you want to have in your satis repository inside the classic composer require key, using a "*" constraint to make sure all versions are selected, or another constraint if you want really specific versions.

{
    "repositories": [
        { "type": "vcs", "url": "http://github.com/mycompany/privaterepo" },
        { "type": "vcs", "url": "http://svn.example.org/private/repo" },
        { "type": "vcs", "url": "http://github.com/mycompany/privaterepo2" }
    ],
    "require": {
        "company/package": "*",
        "company/package2": "*",
        "company/package3": "2.0.0"
    }
}

Once you did this, you just run php bin/satis build <configuration file> <build dir>. For example php bin/satis build config.json web/ would read the config.json file and build a static repository inside the web/ directory.

When you ironed out that process, what you would typically do is run this command as a cron job on a server. It would then update all your package info much like Packagist does.

Note that if your private packages are hosted on GitHub, your server should have an ssh key that gives it access to those packages, and then you should add the --no-interaction (or -n) flag to the command to make sure it falls back to ssh key authentication instead of prompting for a password. This is also a good trick for continuous integration servers.

Set up a virtual-host that points to that web/ directory, let's say it is packages.example.org.

Usage

In your projects all you need to add now is your own composer repository using the packages.example.org as URL, then you can require your private packages and everything should work smoothly. You don't need to copy all your repositories in every project anymore. Only that one unique repository that will update itself.

{
    "repositories": [ { "type": "composer", "url": "http://packages.example.org/" } ],
    "require": {
        "company/package": "1.2.0",
        "company/package2": "1.5.2",
        "company/package3": "dev-master"
    }
}
