Ansible Microshift Role

Overview and scope

The main goal of that project is to deploy the Microshift service by using Ansible tool.

On top of the MicroShift getting started instructions, this role performs the following actions:

• Disable IPv6 as it is a source of problem in cloud environment.
• Give you possibility to disable the swap on the host.
• Can install the Operator SDK framework.
• Create the PV (Persistent Volumes) base on local storage.
• Setup topolvm storage for persistent volume.
• Create an additional user in OpenShift.
• Overwrite the container policy.
• Others.

Role requirements

To run MicroShift, the minimum system requirements are:

• x86_64 or aarch64 CPU architecture
• Red Hat Enterprise Linux 9 with Extended Update Support (9.2 or later)
• 2 CPU cores
• 2GB of RAM
• 2GB of free system root storage for MicroShift and its container images

Besides system requirements, it is necessary to provide a pull-secret.txt content, which can be generated here. and it is configured to your user account. The pull-secret.txt content should be provided as a ansible variable: openshift_pull_secret.

Role Variables

All of the parameters to setup the Ansible role are available in the defaults file.

all:
  vars:
    openshift_pull_secret: |
      < HERE IS pull.secret.txt content >
  hosts:
    microshift.dev:
      ansible_port: 22
      ansible_host: 127.0.0.1
      ansible_user: centos

---
- hosts: microshift.dev
  vars:
    fqdn: microshift.dev

ansible-playbook -i inventory.yaml deploy-microshift.yaml
