Starting from version 1.9.8.2.10, DMS utilizes an external worker container to generate previews and parse emails.

This container requires a minimum of 4GB of free RAM in addition to the necessary overhead for Docker and other applications. Please ensure that your system meets these requirements.

The procedure:

• Pull latest version of config repository
• Pull latest version of deploy_script repository

• Update the commands.conf file by adding the following code block after the add_variable "ES_JAVA_OPTS" "-Xms${ES_XMS} -Xmx${ES_XMX}" line, if it does not already exist:

  elif [ ${1} = "WORKER" ] then add_volume ${NUXEO_TEMPDIR} "/tmp" add_volume ${NUXEO_WINFONTDIR} "/usr/share/fonts/custom-fonts" add_volume ${NUXEO_WINFONTDIR} "/root/.windows_fonts" add_volume ${NUXEO_LOGDIR} "/var/log/worker"

• Configure the nuxeo and cb images to use version 1.9.8.2.10.
• Perform a proper system redeployment.

Troubleshooting:

If the worker container constantly restarts, it may be due to an outdated Docker version.

To resolve this issue, execute a yum update. If the Docker service does not start, you may need to create or update the /etc/docker/daemon.json file with the following content:

{
"storage-driver": "devicemapper"
}
