Run Unbound environment in local K8S

This is a setup for running the Unbound environment in K8S using KinD

Prerequisites

Tools

KinD
kubectl
Buildtools
Lastpass CLI
GNU Base64
Bash 4.4+
direnv to manage environment variables per directory

Setup

Create a Gitlab Personal Access Token with (at least) read_registry access and set it as environment variable GITLAB_TOKEN. Can be done with a .envrc-file in a parent directory:

source_up .envrc
export GITLAB_TOKEN=<xyz>

Create a .buildtools.yaml-file in the parent directory with the following content:

targets:
  local:
    context: kind-unbound
    namespace: default
  staging:
    context: k8s.unbound.se
    namespace: staging
  prod:
    context: k8s.unbound.se
    namespace: default

Creating the cluster

Just run the following:

./setup

Wait for the cluster to be ready. The K8S context should be set automatically. Check what's been deployed by running:

kubectl get pod -A

Stopping/starting the cluster

If you need to stop the cluster to be able to use the exposed ports for other things, run:

docker stop unbound-control-plane

To start it again:

docker start unbound-control-plane

Removing the cluster

To remove the cluster completely, run:

kind delete cluster --name unbound

Cleaning up retained data

The setup stores data for containers in the data-directory. To start from scratch, stop the cluster, empty the directory and start the cluster again.
