• Set the vCenter variables

  1. IP/Host Name of vCenter
  2. vCenter Network
  3. Datastore name
  4. Datacenter name
  5. username and passwords of vCenter Account
  6. Absoluate folder path - e.g /DataCenter/vm/Folder/
  7. VM Power state after being deployed

• Configure your Fedora CoreOS URL and govc version.

  1. Set the Fedora CoreOS stream version. stable is the default

• Configure your CoreDNS VM Settings

  1. VM and Host Name
  2. IP Addr, Gateway, Net Mask, DNS
  3. Number of CPUs
  4. Amount of Memory in MB
  5. Size of the HDD in GBs

• Configure your A Records

  1. Ex: - { name: "server1", ipaddr: "10.0.0.1" }

• Configure your CNAME Records if required

  1. Ex: - { name: "www", alias: "server1" }

Infrastructure Prerequisites

1. vSphere ESXi and vCenter 6.7 or 7.0 installed.
2. A datacenter created with a vSphere host added to it and a datastore exists that has adequate capacity.
3. Ansible (preferably latest) on the machine where this repo is cloned.
   1. Before you install Ansible, install the epel-release, run yum -y install epel-release

USAGE

Run Deploy Playbook

# Deploy the Lab and all components
ansible-playbook deploy-coredns.yml

deploy-aio-lab.yml Extra Variables

skip_ova=true - Skips downloading and deploying the OVA if previous deployed to vCenter. redeploy=true - Deletes existing CoreDNS vm

Expected Outcome

1. Necessary Linux packages installed for the installation
2. Necessary folders [bin, downloads] created
3. govc downloaded and extracted
4. FCOS ova downloaded to the downloads folder
5. CoreDNS VM is created in the designated folder and (in state of) poweredon
