Deploying VSO + Sidecar on Openshift/K8s

Ensure that the kubernetes cluster has no previos deployments of vault or VSO, including no pods, secrets, clusterroles, clusterrolebindings..etc
Create a kubernetes namespace

kubectl create namespace vso

Create a vault namespace

vault namespace create vso

Export the following

export TF_VAR_vault_namespace="vso";
export TF_VAR_vault_public_address="https://vault.hashicorp.cloud:8200";
export TF_VAR_vault_admin_token="XXXXXXX";
export TF_VAR_kubernetes_endpoint="https://kubernetes.hashicorp.com";
export TF_VAR_kubernetes_namespace="vso"

Ensure your kubeconfig path and context are correct in providers.tf for both the kubernetes and helm providers.
Deploy using terraform

terraform init

terraform apply

Check if deployment is successful

kubectl get pod
