how we can access the values provided to notes to a hosts

[lexjwa]

We're looping and chaining up hosts for application servers.

It works fine if we knew what label we would like to use when deploying to application servers.

For example

dep deploy deployment_type=production

But we can have other types such as staging, dev or production for label deployment_type

$environment = 'Production'; // @todo this needs to be the value that was passed in as the deployment_type, first letter capitalized to match enum definition
$environmentValue = EnvironmentType::fromKey($environment)->value;
$servers = Server::active()->where('environment', $environmentValue)->with('instances')->get();
foreach($servers as $server) {
   $hostname = $server->uses_private_network ? $server->private_ip : $server->public_ip;
   foreach($server->instances as $instance) {
       if($instance->isActive()) {
           $deployPath = $instance->deploy_path;
           $instanceType = $instance->isWorker() ? 'worker' : 'application';
           $deploymentType = strtolower($server->environment->key); // "dev"|"staging"|"production"
           host($server->name)
               ->set('remote_user', 'remote_user_name')
               ->set('hostname', $hostname)
               ->set('deploy_path', $deployPath)
               ->set('keep_releases', 10)
               ->set('labels', ['deployment_type' => $deploymentType, 'server_type' => $instanceType]);
       }
   }
}

Is there a way that we could know what value was provided to label deployment_type in loops, so command to deploy is easy to use, perhaps something to list hosts and get what those hosts got in.

For example you can use env:

TYPE=Prod dep deploy all

and get env via getenv();

Thanks for this answer, but I'm a bit confused by it. The question is, when we run:

vendor/bin/dep deploy deployment_type=production

Is it possible to get the value that was provided for deployment_type?

Or are you saying instead of using the deployment_type label at all, we should pass "Prod" (or whatever) as a TYPE PHP environment variable, and fetch its value instead?

Something like this I suppose. But looks like people trying to use selector as input params. Maybe it should be allowed.

Selector right now is not an input params. Consider next selectors:

• dep deploy all
• dep deploy role!=prod
• dep deploy stage=prod and region!=us-east1
