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:

Supported tags and respective Dockerfile links:

-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: yarn

-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

Tools

Composer latest latest latest

Xdebug

By default, xdebug mode set to off, which has close to 0 overhead. If you want to disable the extension completely set PHP_EXTENSIONS_DISABLE=xdebug.

Changelog

Changes per stability tag reflected in git tags description under releases.

Crond

You can run Crond with this image changing the command to sudo -E crond -f -d 0 and mounting a crontab file to ./crontab:/etc/crontabs/www-data. Example crontab file contents:

# min	hour	day	month	weekday	command
*/1	*	*	*	*	echo "test" > /mnt/files/cron

SSHD

You can run SSHD with this image by changing the command to sudo /usr/sbin/sshd -De and mounting authorized public keys to /home/wodby/.ssh/authorized_keys

Adding SSH key

You can add a private SSH key to the container by mounting it to /home/wodby/.ssh/id_rsa

Users and permissions

Default container user is wodby:wodby (UID/GID 1000). PHP-FPM runs from www-data:www-data user (UID/GID 82) by default. User wodby is a part of www-data group.

Codebase volume $APP_ROOT (/var/www/html) owned by wodby:wodby. Files volume $FILES_DIR (/mnt/files) owned by www-data:www-data with 775 mode.

See wodby#22 for more details.

Helper scripts

  • files_chmod – in case you need write access for wodby user to a file/dir generated by www-data on this volume run sudo files_chmod [FILEPATH] script (FILEPATH must be under /mnt/files), it will recursively change the mode to ug=rwX,o=rX

  • files_chown – in case you manually uploaded files under wodby user to files volume and want to change the ownership of those files to www-data run sudo files_chown [FILEPATH] script (FILEPATH must be under /mnt/files), it will recursively change ownership to www-data:www-data
