We need to start Flexmonster data server on ReadOnly RootFileSystem container.

Zvika Kushnirski asked on March 28, 2024

Our security team requires that we launch our containers (AKS PODs) with “ReadOnly RootfileSystem”.
When I configure FlexMonster docker like this, leaving only /tmp and the current Flexmonster server/configuration  directory R/W, FlexMonster-data-server does not run and immediately crashes without any STDERR.
Our docker platform is UBUNTU 20.04  (Dockerfile: "FROM ubuntu:20.04")
 
Question: what additional directories must be writable for the data server to work correctly?

Hello Zvika,

Thank you for reaching out to us.

Kindly note that Flexmonster Data Server needs writable permissions for two directories to work properly:
1. The directory where the executable file is located
2. The directory where the configuration json file is located. It has the default location:

  • On Windows – C:/ProgramData/FlexmonsterDataServer/
  • On macOS and Ubuntu/Linux – ~/.local/share/FlexmonsterDataServer/ (will resolve to /home/[current_user]/.local/share/FlexmonsterDataServer/)

For more details, please visit our docs: https://www.flexmonster.com/doc/getting-started-with-data-server/#package-structure

Please let us know if the Data Server works well after adding the necessary permissions to the two mentioned directories.

Kind regards,
Nadia
