unable to provide the crypt key when using the existing database

[venkateshjiva]

Hi Support,

I am creating the local instance with docker setup and used the database entry point to use the existing database for the application, when running the deploy command throwing the error like Missing Crypt key for upgrading magento, can you suggest how we can provide crypt key on docker configuration?

Hello fellow Coder!
Sadly it's not specified during the local docker installations but you need to have an existing mageroot/app/etc/env.php during the installation process. There you should add a crypt key.

    echo "<?php return array('cache'=> array ('frontend' => array ('default' => array ('backend' => 'Cm_Cache_Backend_Redis','backend_options' => array ('server' => 'redis','port' => '6379','database' => 1,),),'page_cache' => array ('backend' => 'Cm_Cache_Backend_Redis','backend_options' => array ('server' => 'redis','port' => '6379','database' => 2,),),),),'MAGE_MODE' => 'production','cron' => array ('enabled' => 0,),'crypt' =>array ('key' => '0000athirtytwocharacterstring000',),);" >> app/etc/env.php

here is a command to generate the env.php with crypt key, don't forget to use a different crypt key on you public store
