# * default user is superuser (root), so allow them
# * put cache directory in a readable/writable location
# _Note_: When running `composer` in container, use `--no-cache` option

# Install dependencies:
# * bash: for shell access and scripting
# * curl: for downloading build tools (box, micro.sfx)
# * libzip-dev: for composer packages that use ZIP archives
# _Note (Alpine)_: `--no-cache` includes `--update` and keeps image size minimal
#
# Then install PHP extensions

# _Note (Hadolint)_: No version locking, since Alpine only ever provides one version
