* Cilium v1.14 seems to have problems reliably accessing the apiserver via default in-cluster service discovery (relies on kube-proxy instead of DNS) after some time * Configure Cilium agents to use the DNS name resolving to the cluster's load balanced apiserver and port. Regrettably, this relies on external DNS rather than being self-contained, but its what Cilium pushes users towards
terraform-render-bootstrap
terraform-render-bootstrap is a Terraform module that renders TLS certificates, static pods, and manifests for bootstrapping a Kubernetes cluster.
Audience
terraform-render-bootstrap is a low-level component of the Typhoon Kubernetes distribution. Use Typhoon modules to create and manage Kubernetes clusters across supported platforms. Use the bootstrap module if you'd like to customize a Kubernetes control plane or build your own distribution.
Usage
Use the module to declare bootstrap assets. Check variables.tf for options and terraform.tfvars.example for examples.
module "bootstrap" {
source = "git::https://github.com/poseidon/terraform-render-bootstrap.git?ref=SHA"
cluster_name = "example"
api_servers = ["node1.example.com"]
etcd_servers = ["node1.example.com"]
}
Generate assets in Terraform state.
terraform init
terraform plan
terraform apply
To inspect and write assets locally (e.g. debugging) use the assets_dist Terraform output.
resource local_file "assets" {
for_each = module.bootstrap.assets_dist
filename = "some-assets/${each.key}"
content = each.value
}
