create an alias to multiple hosts

[shopapps]

Hi Superbrains out there...

The scenario:

let's say I have 6 staging and 6 production web servers behind a loadbalancer. Each one is individually accessible via

• production1.mywebsite.co.uk
• production2.mywebsite.co.uk
  ...
  or...
• staging1.mywebsite.co.uk
• staging2.mywebsite.co.uk
  ...

The deploy command I would like

What I am trying to achieve (and just can't get my head around how to do it without an interim bash script) is to have a simple deploy command for my devs to use, so they don't cock things up during deployment... :-)

# To deploy the develop branch to multiple staging servers
dep deploy staging

# To deploy a specific branch to multiple  staging servers
dep deploy staging --branch="feature/xyz"

I would like this to then deploy to all of our staging servers the same code

then for production we would like to do:

# To deploy the master branch to multiple production servers
dep deploy production

# To deploy a specific branch to multiple production servers
dep deploy production --branch="hotfix/xyz"

then the equivalent for rollback

dep rollback staging
dep rollback production

currently, it seems like we would have to run multiple commands to achieve this:

dep deploy production1.mywebsite.co.uk --branch="master"
dep deploy production2.mywebsite.co.uk --branch="master"
dep deploy production3.mywebsite.co.uk --branch="master"
dep deploy production4.mywebsite.co.uk --branch="master"
dep deploy production5.mywebsite.co.uk --branch="master"
dep deploy production6.mywebsite.co.uk --branch="master"

Does anyone out there have a small snippet of their deploy.php file they can share to give me some hints on how to achieve this?

as a start point I tried this in my deploy.php
(yes I'm using forge, and no I don't want to use the built-in forge deployment script as it's a pain when you have lots of different frontend and backend production servers to deploy to at the same time - lol ):

set('application', 'mywebsite');
set('root_dir', '/home/forge/deploy');

host('production1.mywebsite.co.uk', 'production2.mywebsite.co.uk')
    ->set('alias', 'production')
    ->setHostname('mywebsite.co.uk')
    ->setRemoteUser('forge')
    ->setIdentityFile( '~/.ssh/id_rsa')
    ->set('stage', function () {
        return (input()->hasOption('stage')) ? input()->getOption('stage') : 'production';
    })
    ->set('branch', function () {
        return (input()->hasOption('branch')) ? input()->getOption('branch') : 'master';
    })
    ->setDeployPath('{{root_dir}}/{{application}}/{{stage}}')
    ->set('labels', [
        'type' => 'laravel',
        'env' => 'production',
    ])
;

but this triggers an error:

 Can not update alias of the host.
  This will change only host own alias,
  but not the key it is stored in HostCollection.

how to test it

To test I would like to be able to do this:

in deploy.php

task('test', function () {
    writeln('The {{alias}} is {{hostname}}');
    run('whoami');
});

then run

dep test production

expected behaviour
multiple responses from lots of servers.

current behaviour

dep test production
task test
  ⠏ 
In HostCollection.php line 21:
                                
  Host "production" not found.

host('production1.mywebsite.co.uk', 'production2.mywebsite.co.uk')
-   ->set('alias', 'production')
    ->setHostname('mywebsite.co.uk')
    ->setRemoteUser('forge')
    ->setIdentityFile( '~/.ssh/id_rsa')
-   ->set('stage', function () {
-        return (input()->hasOption('stage')) ? input()->getOption('stage') : 'production';
-    })
+   ->set('stage', 'production')
    ->set('branch', function () {
        return (input()->hasOption('branch')) ? input()->getOption('branch') : 'master';
    })
    ->setDeployPath('{{root_dir}}/{{application}}/{{stage}}')
    ->set('labels', [
        'type' => 'laravel',
        'env' => 'production',
    ])
;

Deploy with:

dep deploy env=production

Thanks Anton, I thinks that's minimal enough that they are unlikely to make mistakes.

much appreciated 😎
