Role Name

This Role enables easy scalable deployment of the Bitflux Memory optimization system.

Requirements

No additional dependencies

Role Variables

Default variables are as follows

• bitflux_deviceIdTemplate: (Defaults to inventory_host_name)should be something that will be unique per machine. Using hostnames, or inventory values works well. Optionally adding a suffix may be helpful.
• bitflux_key: (default is an invalid string, required)This is the token or key used to enable bitflux to run, found on cloud.bitflux.ai under credentials, noted as APIToken
• bitflux_enableKernel: (default false) setting this field to true, replaces the default kernel with a patched version of the same, enabling proactive memory management. kernel patch details can be found at https://github.com/resurgentech/bitflux_patch

This naming may change for clarification They are named this way to avoid confusion, and allow overriding of individual variables.

Dependencies

There are no other dependencies.

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

Minimal example - no Kernel

- hosts: servers
  roles:
     - { role: peterjweir.bitflux, bitflux_key: "{{mykeyvar}}"}

Minimal example - enable Proactive Reclaim Kernel

- hosts: servers
  roles:
     - { role: peterjweir.bitflux, bitflux_key: "{{mykeyvar}}", bitflux_enableKernel: true}

Override Device Id Template

- hosts: servers
  roles:
     - { role: peterjweir.bitflux, bitflux_key: "{{mykeyvar}}", bitflux_deviceIdTemplate: "{{inventory_hostname_short}}-mysql" }

Enable Kernel Reclaim

- hosts: servers
  roles:
     - { role: peterjweir.bitflux, bitflux_enableKernel: true, bitflux_key: "{{mykeyvar}}", bitflux_deviceIdTemplate: "{{inventory_hostname_short}}-mysql" }
