Command Reference

We included a few commands in the /usr/local/bin directory to help you with your development experience. These commands are available in the serversideup/php image.

Since our images are unprivileged by default, you'll need to switch to the root user to run these commands. This is a security feature that ensures that your container is as secure as possible.

Official PHP Docker Commands

Since our images are based off the official PHP Docker images, any commands from the Official PHP Docker images are available in our images. You can find the full list of commands on the official PHP Docker images documentation.

docker-php-serversideup-dep-install-alpine

This command will detect the operating system and install packages if it is an Alpine based system. This is helpful if you're building multiple operating systems from the same Dockerfile.

Example - Installing the git package on Alpine
# Usage: docker-php-serversideup-dep-install-alpine [alpine-packages]
docker-php-serversideup-dep-install-alpine git

docker-php-serversideup-dep-install-debian

This command will detect the operating system and install packages if it is a Debian based system. This is helpful if you're building multiple operating systems from the same Dockerfile.

Example - Installing the git package on Debian
# Usage: docker-php-serversideup-dep-install-debian [debian-packages]
docker-php-serversideup-dep-install-debian git

docker-php-serversideup-entrypoint

Our default entrypoint script that is used for all images.

docker-php-serversideup-install-php-ext-installer

This is an internal helper script to shorten up the syntax for the installation of the PHP extension installer.

Example - Installing the PHP extension installer
# Usage: docker-php-serversideup-install-php-ext-installer [version]
docker-php-serversideup-install-php-ext-installer 2.2.0

docker-php-serversideup-set-file-permissions

This command is used to set the file permissions of a service in the container. This is useful for development environments where you want to match the user and group ID of the host machine.

Learn more about working with file permissions →

Example - Setting the file permissions of the NGINX service
# Usage: docker-php-serversideup-set-file-permissions --owner USER:GROUP
docker-php-serversideup-set-file-permissions --owner 1000:1000

The above command will automatically detect the service and update the file permissions accordingly.

docker-php-serversideup-set-id

This command is used to set the user and group ID of the www-data user in the container. This is useful for development environments where you want to match the user and group ID of the host machine.

docker-php-serversideup-s6-init

This command is used to copy our entrypoint scripts into the S6 Overlay scripts directory. This is useful if you're using S6 Overlay and want to ensure your scripts are executed in the correct order.

docker-php-serversideup-s6-install

This is a command used at build time to install a specific version of S6 Overlay.

install-php-extensions

This command is a wrapper around the docker-php-ext-install command that comes with the official PHP Docker images. This command allows you to install PHP extensions with a single command.
