# plugins to install while building the container. By default no plugins are

# 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

# Control whether libreoffice will be installed, enabling exports to DOC/PDF/ODT formats.
# By default, it is not installed.

# EXAMPLE:
#   INSTALL_LIBREOFFICE=true

# 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).

# Running as non-root enables running this image in platforms like OpenShift
# that do not allow images running as root.
