I needed PHP version 8.1 for my CLI in DevKinsta Docker, but it was 7.4. So I found this quick way to change to version 8.1.
Login as super user
$ docker exec -u 0 -it devkinsta_fpm bash
Change PHP version CLI
$ sudo update-alternatives –set php /usr/bin/php8.1
Login as www-data user
$ docker exec -u www-data -it devkinsta_fpm bash
Move to WordPress project
$ cd /public/projectname
Run WP CLI commands
$ wp —info
