# Automated Installation

Tomcat, InfluxDB, and Database Schemas are installed and upgraded automatically with this tool. This is the easiest way to install or upgrade FlexDeploy. This is supported only on Linux vms and hosts. It works for installs and upgrades of the FlexDeploy Production Docker image, but not the image for POCs. It is not compatible with Kubernetes or Helm Charts. In those cases, a Manual installation below is advisable.
