Introduction

These are production-oriented PHP container images built on Alpine Linux and published to Docker Hub under adamrollogi/. They are built for linux/amd64 and linux/arm64, so the same tag runs on Intel servers, Graviton instances and Apple Silicon laptops.

The design goals are simple:

• Predictable. The exact PHP release in every tag is pinned and verified at build time. A tag never silently changes its PHP version underneath you.
• Secure by default. Containers run as an unprivileged user, carry no setuid binaries, keep their configuration root-owned, and are scanned before any tag is published.
• Configurable without rebuilding. Everything from memory_limit to TLS ciphers is an environment variable, and any php.ini or PHP-FPM setting can be set directly.
• Observable. Every log line is tagged with the service that wrote it, with a JSON mode for log shippers.

Image hierarchy

alpine:3.24
  └── adamrollogi/base            tini, Supervisor, bash, curl, git, logging helpers
        └── adamrollogi/php       PHP CLI, Composer, extensions
              └── adamrollogi/php-nginx      Nginx, PHP-FPM, HTTPS, health endpoint
                    └── adamrollogi/php-nginx-dev   Xdebug, dev defaults

Each image inherits everything from its parent, including environment variables, entrypoint behaviour and the logging layout, so a setting you learn on one image works the same on the others.

Supported PHP versions

PHP 8.6 is published while it is still a release candidate. Treat it as a preview until 8.6.0 ships; its exact tag follows Alpine's spelling, for example 8.6.0_rc3. See Tags and versions for how tags are named and how new releases arrive.
