By default, Symfony Docker uses Debian-based FrankenPHP Docker images. This is the recommended solution.
Alternatively, it's possible to use Alpine-based images, which are smaller but are known to be slower, and have several known issues.
To switch to Alpine-based images, apply the following changes to the Dockerfile:
-FROM dunglas/frankenphp:1-php8.3 AS frankenphp_upstream
+FROM dunglas/frankenphp:1-php8.3-alpine AS frankenphp_upstream
-# hadolint ignore=DL3008
-RUN apt-get update && apt-get install -y --no-install-recommends \
- acl \
- file \
- gettext \
- git \
- && rm -rf /var/lib/apt/lists/*
+# hadolint ignore=DL3018
+RUN apk add --no-cache \
+ acl \
+ file \
+ gettext \
+ git \
+ ;
