homelab/step-by-step.md

Almost automated step by step walkthrough of full lab deployment

This is will be the complete walkthrough of the deployment of my homelab.

This repo is a mono-repo that is broken up into three sections:

• infra-config
• cluster-config
• apps

Getting Started

• On a PC/laptop, clone this git repo

  (Ansibilze this process (below) )

• Create your vault file for secrets (and store somewhere safe)

  echo 'master-ansible-password' > ~/.vault_pass.txt
  chmod 644 ~/.vault_pass.txt
  

• Add "export ANSIBLE_VAULT_PASSWORD_FILE=~/.vault_pass.txt" to your shell profile.

• Create vault file

  cd homelab/group_vars/all
  ansible-vault create vault
  

• Modify ansible variables for your environment

• From laptop run ansible playbook to:

  cd homelab/infra-config
  ansible-playbook -i inventory.yml 03-infra01-server/install.yml
  

  • Install ansible-core
  • Copy .vault_pass.txt from laptop and set env variable
  • Clone git repo
  • Install ansible required packages

  scp ~/.vault_pass.txt infra01:.
  ssh infra01
  
  cd homelab
  ansible-galaxy collection install -r requirements.yml
  ansible-playbook -i inventory.yml 10-sno-hub-cluster/install.yml

Hub Cluster In Progress

• Prepare matchbox to install hub cluster

  Running this playbook will configure Matchbox to wait for the sno-cluster to boot via iPXE and will install Single Node OpenShift. All configuration files are built from templates driven from Ansible variables.

  cd homelab
  ansible-playbook -i inventory.yml 10-sno-hub-cluster/install.yml
  

• PXE boot the SNO host

  Boot host to boot options menu:

  • <F12> for Dell 7050

  Select NIC with matching MAC to boot from

• Monitor installation process

  openshift-install --dir homelab/10-sno-hub-cluster/03-openshift-image agent wait-for bootstrap-complete --log-level=debug
  

• Admin password and kubeconfig are in the homelab/10-sno-hub-cluster/03-openshift-image/auth directory

• Bootstrap ACM

  From laptop/infra server:

  cd homelab
  oc apply -k hub-cluster-bootstrap
  oc apply -f ~/ocp/doppler-token.yaml
  oc apply -k hub-cluster-bootstrap
