# plugins to install while building the container. By default no plugins are
# installed.
# If given a value, it has to be a space-separated, quoted list of plugin names.

# EXAMPLE:
#   ETHERPAD_PLUGINS="ep_codepad ep_author_neat"
ARG ETHERPAD_PLUGINS="ep_adminpads"

# By default, Etherpad container is built and run in "production" mode. This is
# leaner (development dependencies are not installed) and runs faster (among
# other things, assets are minified & compressed).
ENV NODE_ENV=production

# Follow the principle of least privilege: run as unprivileged user.
#
# Running as non-root enables running this image in platforms like OpenShift
# that do not allow images running as root.
# Also fix issue that would arise when installing libreoffice
