Destroy everything

WARNING: Following this guide will completely remove your infrastructure from your Exoscale account. There is no way to rollback (even if you have backups, and you rebuild the infrastructure, you will loose your ingress pool public IP addresses).

Destroying the Kubernetes cluster

1. Edit the terraform-kubernetes/main.tf file: Search for the exoscale_nlb.ingress resource definition:

resource "exoscale_nlb" "ingress" {
  for_each = local.platform_components.kubernetes.ingresses

  zone        = local.platform_zone
  name        = "${local.platform_name}-ingress-${each.key}"
  description = "Ingress load balancer (${each.key})"

  lifecycle {
    prevent_destroy = true
  }
}

2. Comment the lifecycle block:

resource "exoscale_nlb" "ingress" {
  for_each = local.platform_components.kubernetes.ingresses

  zone        = local.platform_zone
  name        = "${local.platform_name}-ingress-${each.key}"
  description = "Ingress load balancer (${each.key})"

  # lifecycle {
  #   prevent_destroy = true
  # }
}

3. Then save the file with the commented block, and destroy the Kubernetes infrastructure: from the terraform-kubernetes sub-directory, run terraform destroy.
4. Undo the change made at step 1.
5. If applicable, fom the terraform-cloudflare sub-directory, run terraform destroy.

Destroying the Base configuration

1. From the terraform-base-configuration sub-directory, run terraform destroy.

Destroying the Base infrastructure

1. Remove everything from the etcd and vault snapshost buckets (using the CLI, s3cmd, Web UI, etc.).
2. From the terraform-base sub-directory, run terraform destroy.

Manual tasks

1. Delete templates from your Exoscale account:
   • Etcd x.y.z
   • Kubernetes x.y control plane
   • Kubernetes x.y node
   • Vault x.y.z
2. Cleanup artifacts (files in the artifacts sub-directory):
   • *.json
   • *.txt
