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

For our images that DO NOT use S6 Overlay, this is our default entrypoint script.

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.

docker-php-serversideup-install-php-ext-installer 2.2.0

docker-php-serversideup-set-file-permissions

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.
