Implement host selector

[antonmedv]

I'm looking for somebody to develop "host selector" feature.

Idea:

• A host can have few labels: ['stage' => 'prod', 'role' => 'db', 'tier' => 'df.2']
• User "selects" on which hosts to run a deploy: dep deploy 'stage=prod'
• Or can define custom selectors in code selector('prod', 'stage=prod AND (role=db OR role=app)') dep deploy prod
• Also default selector can be defined.
• Selector features: label=value, and/or, brackets (...). Maybe also regexp label~=^v.+?

Code points:

• https://github.com/deployphp/deployer/blob/master/src/Selector/Selector.php#L41-L56

It works well when there are few different application servers to deploy to. In my case I first build on the build server using

//To build on the build server

localhost('local')
    ->set('deploy_path', __DIR__ . '/.build')
    ->set('keep_releases', 10)
    ->set('stage', 'local');

I can run vendor/bin/dep build local and once build is done on the build server. It is time to deploy to 10+ application servers.

When I run vendor/bin/dep deploy all it upload the target directory to the 10+ application servers but it also build on the build server which I do not need to when deploying to application servers.

Do we have option to exclude localhost() when we use special selector all ? selector all

I tried to use stage with vendor/bin/dep deploy production all but it does not work with that as well.

host($serve_name)
              ->set('remote_user', 'forge')
              ->set('hostname', $public_ip)
              ->set('deploy_path', $deploy_path)
              ->set('stage', 'production');

No, but you can set a label on every server like this:
host()->set('label', ['servier_type' => 'app']) and then dep deploy server_type=app

@Schrank thank you for your reply.

I added label to hosts and tried this command.

vendor/bin/dep deploy server_type=production

It gives me error
No host selected. Please, check your selector:
server_type=production

This is how I am chaining hosts.
if(count($servers) > 0){
    foreach ($servers as $s_key => $server)
    {
        $public_ip = $server->public_ip;
        $serve_name = $server->name;
        foreach ($server->instances as $i_key => $instance)
        {
            $deploy_path = $instance->deploy_path;
            host($serve_name)
                ->set('remote_user', 'forge')
                ->set('hostname', $public_ip)
                ->set('deploy_path', $deploy_path)
                ->set('stage', 'production')
                ->set('label', ['server_type' => 'production']);
        }
    }
}

To select host then I use
vendor/bin/dep deploy all server_type=production
or
vendor/bin/dep deploy server_type=production all
And the problem is still there.

Note:
If I run vendor/bin/dep deploy it gives me list to select hosts to deploy to (comma separated) I can use 1,2,3,4.. excluding the localhost. It works fine this way. But I want to exclude the need to select hosts like this.

[antonmedv]

It’s labels with s. Not label.

[antonmedv]

In process of writing docs on it.

[lexjwa]

@antonmedv Thank you.

vendor/bin/dep deploy server_type=production works like a charm.

and thank you for putting the docs together for v7.

Was this error worked upon .. i cant seem to find a solution for the deployer
host('example.com')
->setHostname('127.0.123.23')
->setRemoteUser('root')
->set('stage','production')
->setDeployPath( '/var/www/html/yotta-api');

Hi @CodeNinjaUG, thanks for your comment! But unfortuantely I have no clue what you are talking about 🙈

• What did you try?
• What did you expect?
• What happened instead?

Happy to help! Maybe it makes sense to open another issue!
