Flex deployment and administration requires a UNIX-compatible system. At present time, officially tested and supported desktop configurations are:

  1. MacOS (with Apple Silicon ARM64 architecture)
  2. Ubuntu Linux LTS 24.04+ (AMD64 and ARM64 architectures).

Installation

Ansible's installation can be done through 2 distinctives way:

  1. Through OpsCtl (recommended procedure).
  2. Through manual installation.

Manual installation on MacOS

Usage

Deployments through Ansible works by concurrently running various tasks over server instances, through SSH remote connection. It is then essential for the host running Ansible to use an SSH private key that is trusted by the server instances to be targeted.
