I to linked 3 separate containers together:
my goal is to run wp-cli installation before the source code being copy into the nginx container.
issues:
- trying to run installation script of wp-cli from Dockerfile (my-nginx image) works fine, but when i try running any wp-cli commands it returns error:
env: can't execute 'php': No such file or directory - wp-cli installation script (with the right dependencis) works also on dockerfile.php-fpm (my-php image), it returns an error as well :
Error: YIKES! It looks like you're running this as root. You probably meant to run this as the user that your WordPress install exists under.and offers me to run this command with the flag --allow-root, wich is bad in this case becuase i want to use wp user permissions. or to run this command as another user.
core configuretions

wp-cli integration is cloned from : https://github.com/conetix/docker-wordpress-wp-cli

general questions:
- what is the best practice for users premissions inside dockers?
- wp-cli integration from https://github.com/conetix/docker-wordpress-wp-cli/blob/master/wp-su.sh uses www-data user - should i add this user to my docker, and if so - to wich one? ngnix or php-fpm and why.
- running wp donlowd core from php-fpm container appaers as if it download the files but when i try to exec when its running, none of this files shown at /var/www/html . is there a certain way to order images file mounting?
- why does 'php' isn't available command from my-nginx if i volume
my-php image? i must install php also on this image?
