OOD RStudio-serve app for Analysis Environment (Beta)
--server-data-dir "${TMPDIR}" redirects output of PIDs from /var/run/rstudio-rsession to ${TMPDIR}.
--secure-cookie-key-file "${TMPDIR}/rstudio-server/secure-cookie-key" redirects output of secure-cookie-key from /tmp/rstudio-server to $TMPDIR. Necessary to avoid conflict where multiple RStudio Server instances are running and generate same hard-coded file.
--database-config-file "${DBCONF}" sets the path for a new database config requirement in 1.4.1717.
Your $TMPDIR location needs to be unique for this to work. We use our queueing system to set a unique $TMPDIR per job. You can also use export TMPDIR="$(mktemp -d)" within template/script.sh.erb.
