Playbooks and Templates to deploy resorces in my home lab

Ansible

Ansible directory and file structure follows the recommendations here: (Best Practices)[https://docs.ansible.com/ansible/2.8/user_guide/playbooks_best_practices.html]

Deploy all playbooks

ansible-playbook -K -i hosts --extra-vars "proxy_admin_username= proxy_admin_password= vm_root_pass=" site.yml

Tagged Deployments

DHCPD Deployment

ansible-playbook -K -i hosts --tags dhcpd site.yml

VIRT Deployment

ansible-playbook -K -i hosts --extra-vars vm_root_pass="" --tags virt site.yml

BIND Deployment

ansible-playbook -K -i hosts --tags bind site.yml

NFS Deployment

ansible-playbook -K -i hosts --tags nfs site.yml

Kubernetes Cluster Deployment

1 - Generate base kubernetes node image with latest kubelet/kubeadm and other required packages.

cd homelab/image-builder-blueprints

# Modiffy and push the blueprint
composer-cli blueprints push kubernetes_node.toml

# Check blueprint
composer-cli blueprints list
composer-cli blueprints show kubernetes_node
composer-cli blueprints depsolve kubernetes_node

# Build image
composer-cli compose start kubernetes_node qcow2
# Check status
composer-cli compose status
# Download image by UUID
composer-cli compose image UUID

2 - Deploy the virtual machines using Terraform

cd homelab/terraform/cluster_deploy

TF_VAR_redhat_email=<ReplaceWithRedHatEmail> TF_VAR_redhat_password='<ReplaceWithRealPassword>' TF_VAR_ssh_public_key=$(cat ~/.ssh/id_rsa.pub) TF_VAR_base_image=<base image path> terraform apply -var-file=homelab.tfvars

3 - Install kubernetes and configure cluster using ansible

cd homelab/ansible

ANSIBLE_HOST_KEY_CHECKING=False ansible-playbook --private-key=/home/erik/.ssh/id_rsa -i hosts k8s_cluster.yml -K

4 - Install rbac roles, service mesh, and other cluster applications

These terraform configs will install essential configurations / applications such as:

• Service Mesh
• Certificate Manager
• NFS Storage Class
• OpenID Connect (OIDC) Authentication
• Roles & RoleBindings

cd homelab/terraform/cluster_config

terraform apply -var-file=variable.tfvars
