For Linux deployments, 64-bit Linux-based OS is required. The following table shows the Linux distributions supported along with the corresponding minimum supported version. Composer Server also uses Java and PostgreSQL. Ensure that the appropriate version of these tools are used in the deployment of Composer in your operating environment.
|Red Hat||7 & 8|
|Java||11.0.5 (or later)|
|Windows Server||2012 R2, 2016, 2019|
Important CentOS 8 Information
CentOS 8 is no longer supported by Red Hat Linux (RHEL). Use CentOS 7 instead.
Important Ubuntu Information
Ubuntu users who have Composer or Zoomdata versions earlier than 5.8 installed must first remove the legacy repository before upgrading Composer 5.8 or later. Use this command:
sudo rm -f /etc/apt/sources.list.d/saltstack.list
For RPM and Ubuntu installations, the following server specifications are recommended:
- 64 GB RAM (minimum is 16 GB)
- 500 GB disk space
- 16 cores

Composer uses a packaged PostgreSQL v12 database instance to store its metadata and strongly recommends using this instance due to the specific configuration and version employed. If you would like to use another PostgreSQL instance, contact Technical Support for further guidance.
