Build failed: groovy.lang.MissingPropertyException: No such property:
PHPIZE_DEPS. This whole file is rendered through
constructTemplate.groovy's SimpleTemplateEngine before it ever becomes
a real Dockerfile — bare $IDENTIFIER is Groovy GString interpolation
syntax, same as ${IDENTIFIER}, so it tried resolving PHPIZE_DEPS
against the render binding (which only has `version`) instead of
leaving it as literal shell syntax for docker-php-ext-install to
expand at RUN time. \$ is the correct escape for a literal dollar sign
in SimpleTemplateEngine output.
