Docker Images

❗For better reliability we release images with stability tags (wodby/php:8-X.X.X) which correspond to git tags. We strongly recommend using images only with stability tags.

About images:

• All images are based on Alpine Linux
• Base image: official php
• GitHub actions builds
• Docker Hub
• Helm chart

Supported tags and respective Dockerfile links:

• 8.5, 8, latest [(8/Dockerfile)]
• 8.4 [(8/Dockerfile)]
• 8.3 [(8/Dockerfile)]
• 8.2 [(8/Dockerfile)]
• 8.5-dev, 8-dev, dev [(8/Dockerfile)]
• 8.4-dev [(8/Dockerfile)]
• 8.3-dev [(8/Dockerfile)]
• 8.2-dev [(8/Dockerfile)]
• 8.5-dev-macos, 8-dev-macos, dev-macos [(8/Dockerfile)]
• 8.4-dev-macos [(8/Dockerfile)]
• 8.3-dev-macos [(8/Dockerfile)]
• 8.2-dev-macos [(8/Dockerfile)]

-dev

Images with -dev tag have a few differences:

• sudo allowed for all commands for wodby user
• PHP source code available under /usr/src/php.tar.xz
• PHP_FPM_CLEAR_ENV is set to no by default
• Additional packages installed: tig, tmux, yarn and npm

-dev-macos

Same as -dev but the default user/group wodby has uid/gid 501/20 to match the macOS default user/group ids.

Supported architectures

All images built for linux/amd64 and linux/arm64
