Change wp-cli PHP version in devkinsta_fpm container?

[ryanb (Ryan)]

I’m unable to use wp-cli in the devkinsta_fpm docker container because my site requires PHP 8.1 but the default PHP in the container is 7.4.

www-data@f04de6273eca:/www/kinsta/public$ ls -l /etc/alternatives/php
lrwxrwxrwx 1 root root 15 Mar 14  2024 /etc/alternatives/php -> /usr/bin/php7.4

So when I run the wp command it crashes on the website code that requires 8.1. Is there a way to run wp-cli in the container with PHP 8.1?

Hello @ryanb

Thank you for the question above.

In that local docker container , could you please run this command (run as root ):
update-alternatives --config php
it would show you to change the PHP version (7.4) to 8.1 for example, something like this:

once changed to PHP 8.1 , you may want to try to run the WP CLI again with your WP site which requires PHP 8.1 and see if that would work properly as expected?

Best regards,

When I tried that before I got a permission denied error and when I tried with sudo I didn’t know the password. Then when you said (run as root) it occurred to me, I have been going into the container as www-data so that when I created files they would be owned by the web server. I went in again as root and it worked. Thanks!
