Configuration¶

Cluster¶

Operational Environment¶

Operational Environment configuration file named ops-env-cfg.yaml, should be placed next to the cluster's installation files.

Example operational environment configuration file:

# Copyright (c) 2024, Onteon Tech and/or its affiliates.
# All rights reserved.
# Use is subject to license terms.

---
operationsEnvironment:
  ssh:
    user: "user"
    keyPath: "~/.ssh/id_rsa"
    port: 22
  roles:
    clusterManagers:
      primary:
        ip: "10.10.10.1"
      secondary:
        ip: "10.10.10.2"
    workers:
      - "10.10.10.3"
      - "10.10.10.4"
  requirements:
    cpu: 4
    mem: 8
    cpuExtensions:
      - "avx"
    distro:
      name: "ubuntu"
      version: "20.04"
  drbd:
    disk: "vdb"

ssh.user¶

SSH user account to use for authentication.

ssh.keyPath¶

SSH keys enable noninteractive login but when they are used they have to either:

• have empty password
• be added to a SSH key agent on the machine that creates the SSH connections.

ssh.port¶

SSH port to use for authentication.

roles.clusterManagers.primary.ip¶

IP address that is associated with the primary cluster manager.

roles.clusterManagers.secondary.ip¶

IP address that is associated with the secondary cluster manager.

roles.workers¶

IP addresses that are associated with worker nodes.

requirements.cpu¶

This value should not be changed

Number of required CPU cores.

requirements.mem¶

This value should not be changed

Size of required system memory.

requirements.cpuExtensions¶

This value should not be changed

Required CPU extensions (for example vector extension).

requirements.distro.name¶

This value should not be changed

Required operating system distribution name.

requirements.distro.version¶

This value should not be changed

Required operating system distribution version.

drbd.disk¶

Physical disk to be used for populating as a DRBD resource for replication.

Application Environment¶

Application Environment configuration file named app-env-cfg.yaml, should be placed next to the cluster's installation files.

Example application environment configuration file:

# Copyright (c) 2024, Onteon Tech and/or its affiliates.
# All rights reserved.
