System Requirements

To install and use nevisAdmin 4, respect the following system requirements:

• nevisAdmin 4 runs on
  • nevisAppliance (admin4 image),
  • Docker / Kubernetes, or
  • RHEL 7/8 server.
• nevisAdmin 4 requires between 4 GB and 16 GB of RAM and between 2 and 6 CPU cores.
  • The amount of RAM and cores required for your setup primarily depends on the following factors:
    • Project size: Amount of patterns in the project and total project size in MB, including attachments.
    • Number of projects that are edited/updated concurrently.
    • Number of deployments that are executed concurrently.
    • Number of target systems and instances that are deployed during one deployment.
  • Vertical scaling is supported: You can increase RAM and CPU cores as needed.
    • The Java Virtual Machine (JVM) can pose limitations to the vertical scaling: Adding more RAM or cores does not always increase the performance of Java applications.
  • These numbers apply to production setups. For testing or development, performance may also be acceptable with less RAM or cores.
• The managed target systems (deployment hosts) must run on RHEL 7/8, nevisAppliance or on Kubernetes.
• For supported Kubernetes platforms and versions, see Example Installation on Azure.
• MariaDB 10.3.x is required.
  • You can connect only one nevisAdmin 4 instance (server process) to the same database. Horizontal scaling is not supported on the same database.
• For version control of configuration projects, nevisAdmin 4 relies on a remote Git repository.
  • nevisAdmin 4 has been tested to work together with Atlassian Bitbucket, GitLab, GitHub, and Gitea.
• nevisAdmin 4 requires a recent Java 1.8 version.
• nevisAdmin 4 always runs as nvbuser.
• For the Web GUI, browser support is as follows:
  • Officially supported and tested:
    • Chrome, latest version
  • The following may work, but there is no support:
