# 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=
# Control whether abiword will be installed, enabling exports to DOC/PDF/ODT formats.
# By default, it is not installed.
# If given any value, abiword will be installed.
#
# EXAMPLE:
# INSTALL_ABIWORD=true
ARG INSTALL_ABIWORD=
# Control whether libreoffice will be installed, enabling exports to DOC/PDF/ODT formats.
# By default, it is not installed.
# If given any value, libreoffice will be installed.
#
# EXAMPLE:
# INSTALL_LIBREOFFICE=true
ARG INSTALL_SOFFICE=
# 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.
#
# If any of the following args are set to the empty string, default
# values will be chosen.

# Plugins must be installed before installing Etherpad's dependencies, otherwise
# npm will try to hoist common dependencies by removing them from
# src/node_modules and installing them in the top-level node_modules. As of
# v6.14.10, npm's hoist logic appears to be buggy, because it sometimes removes
# dependencies from src/node_modules but fails to add them to the top-level
# node_modules. Even if npm correctly hoists the dependencies, the hoisting
# seems to confuse tools such as `npm outdated`, `npm update`, and some ESLint
# rules.
