Dynamic hosts

[jackd248]

Hej there,

i'm working on a workflow to implement some kind of a feature branch deployment. Therefore I want to create a dynamic host based on a existing "meta" host on runtime regarding CLI arguments, so running for example the following command:

vendor/bin/dep deploy stage --feature=custom-feature-branch-name

With this, for example the deploy path has to be changed to get('deploy_path') . input()->getOption('feature').

I know, I can handle this by my own using a init task for extending the deployment process:

before('deploy', 'deploy:init');

But this seems to become tricky, when running single commands, e.g. vendor/bin/dep deploy:unlock stage --feature=custom-feature-branch-name.

Is there a possibility to hook in the host definition to handle them globally?

Thanks so far, keep up the good work.

As recipes are just simple PHP code you can do anything.

if (getenv('FEATURE_HOST')) {
    host(getenv('FEATURE_HOST'))
        ->setDeployPath('~/path/' . getenv('FEATURE_HOST'))
...
}

Interesting, so what would be the best way to copy the configuration from an existing host?

$baseHost = Deployer::get()->hosts->get('stage');
$baseHost->setDeployPath($baseHost->getDeployPath() . getenv('FEATURE_HOST'));

Deployer::get()->hosts->set(getenv('FEATURE_HOST'), $baseHost);

And calling them like this:

FEATURE_HOST=custom-feature-branch-name vendor/bin/dep deploy custom-feature-branch-name

Just put configuration not in the host but at top level of the recipe. It will be inherited. https://deployer.org/docs/7.x/basics
