New local multisite install doesnt update application.php

[codecowboy]

On a fresh vagrant trellis multisite install (ubuntu 18.04 host), multisite isn’t actually enabled and I don’t see a networks menu item in the WordPress admin panel.

I tried manually adding the following in application.php as per the docs:

```
/* Multisite */
Config::define('WP_ALLOW_MULTISITE', true);
Config::define('MULTISITE', true);
Config::define('SUBDOMAIN_INSTALL', true); // Set to true if using subdomains
Config::define('DOMAIN_CURRENT_SITE', env('DOMAIN_CURRENT_SITE'));
Config::define('PATH_CURRENT_SITE', env('PATH_CURRENT_SITE') ?: '/');
Config::define('SITE_ID_CURRENT_SITE', env('SITE_ID_CURRENT_SITE') ?: 1);
Config::define('BLOG_ID_CURRENT_SITE', env('BLOG_ID_CURRENT_SITE') ?: 1);
```

wordpress_sites.yml

wordpress_sites:
  multisite.local:
    site_hosts:
      - canonical: multisite.local
        redirects:
          - www.multisite.local
    local_path: ../site # path targeting local Bedrock site directory (relative to Ansible root)
    admin_email: admin@example.test
    multisite:
      enabled: true
      subdomains: true
    ssl:
      enabled: false
    cache:
      enabled: false
    env:
      domain_current_site: multisite.local

A few questions:

Shouldn’t this be automatically added to application.php just by setting multisite to true in wordpress_sites.yml?

Are any other steps required? Do I need to re provision? I have followed the multisite section in the trellis docs but maybe I missed something. It’s also been 3+ years since I used WordPress so maybe multisite settings have moved in the dashboard?
