Unable to update docker install to 4.8.0

Hi all,

I have a server running Matomo 4.7.1 with docker (docker-compose) with image matomo:fpm-alpine.

I want to upgrade to 4.8.0.

I have done docker-compose pull and the new image has been downloaded. When I do docker inspect on this image, I can see "MATOMO_VERSION=4.8.0" that lets me think that this is the good last image.

But after restarting all the docker compose stack, the web page still displaying 4.7.1…

What is the problem, and solution ?
