# Install runtime dependencies.
# - curl for healthchecks
# - gettext for `manage.py compilemessages` (run here to avoid busting build-container cache layers)
# - postgresql-client for `manage.py dbshell`
# - mime-support for `uwsgi --http`
# - libxml for lxml
# - libpng, freetype, libtiff and jpeg2000 support for Pillow
# - skipped libjpeg62-turbo, as mozjpeg is used instead.
# Performing dist-upgrade in case base image is outdated.
