The ACF PRO agency license key is used at least two times in a Trellis site vault, once for composer auth for installing by the now official ACF PRO installer method and another time for setting an environment variable that is set as PHP constant in the Bedrock site configs for automatically activating ACF PRO after plugin installation.
In order to avoid duplication and cluttering, the ACF PRO agency key should be set only once in the vault configuration and then re-used for the aforementioned composer authentication and environment variable addition.
However, while the variable interpolation in composer authentication works fine, it does not for the environment variables, the placeholder is not interpolated to the variable value, hence the ACF PRO activation does not work.
group_vars/production/vault.yml:
# ACF PRO agency license (used by all sites on server and by composer auth)
acf_pro_agency_key: "[...]"
# vault config shared by all sites
vault_wordpress_env_defaults:
# environment variable for setting PHP constant for automatically activating ACF PRO (after installation)
ACF_PRO_LICENSE: "{{ acf_pro_agency_key }}"
composer_authentications:
# Advanced Custom Fields (ACF) PRO plugin
- {
hostname: "connect.advancedcustomfields.com",
username: "{{ acf_pro_agency_key }}",
password: "https://www.website-agency.example.com" # some default (ACF PRO Agency license for unlimited sites)
}
Would this be a candidate for a feature request/bug issue for Trellis implementing variable interpolation for environment variables also?
