Deployment code for Openshift 4.

ironicbadger/ocp4

This repo contains code to deploy Openshift 4 for my homelab. It focuses on UPI with vSphere 6.7u3.

Oct 20th 2020 - The code here is working against 4.6. This version of OCP uses Ignition v3 so is incompatible with prior releases of RHCOS.

Usage

Code for each OCP release lives on a numbered branch. The master branch represents the latest stable iteration and will likely be behind branches. In otherwords, check the number branches first before looking at master.

• This repo requires Terraform 0.13
• Install oc tools with ./install-oc-tools.sh --latest 4.6
• This code use yamldecode - details here https://blog.ktz.me/store-terraform-secrets-in-yaml-files-with-yamldecode/

0. Create ~/.config/ocp/vsphere.yaml for yamldecode use, sample content:

alex@mooncake ~ % cat .config/ocp/vsphere.yaml
vsphere-user: administrator@vsphere.lan
vsphere-password: "123!"
vsphere-server: 192.168.1.240
vsphere-dc: ktzdc
vsphere-cluster: ktzcluster

1. Configure DNS - https://blog.ktz.me/configure-unbound-dns-for-openshift-4/
2. Create install-config.yaml

apiVersion: v1
baseDomain: ktz.lan
compute:
- hyperthreading: Enabled
  name: worker
  replicas: 0
controlPlane:
  hyperthreading: Enabled
  name: master
  replicas: 3
metadata:
  name: ocp4
platform:
  vsphere:
    vcenter: 192.168.1.240
    username: administrator@vsphere.lan
    password: supersecretpassword
    datacenter: ktzdc
    defaultDatastore: nvme
fips: false 
pullSecret: 'YOUR_PULL_SECRET'
sshKey: 'YOUR_SSH_PUBKEY'

3. Customize clusters/4.6-staticIPs/terraform.tfvars, clusters/4.6-staticIPs/main.tf, and clusters/4.6-staticIPs/variables.tf with the relevant information. This repo assume you are doing mac address based DHCP reservations.
4. Configure folder on Vmware using the output name from jq -r .infraID <installation_directory>/metadata.json
5. Run make tfinit to initialise Terraform modules
6. Run make create to create the VMs and generate/install ignition configs
7. Monitor install progress with make wait-for-bootstrap
8. Check and approve pending CSRs with make get-csr and make approve-csr
9. Run make bootstrap-complete to destroy the bootstrap VM
10. Run make wait-for-install and wait for the cluster install to complete
11. Enjoy!
