Setup K8S

Task: set up Canonical k8s substrate

Goal

Install and configure Canonical k8s inside the sandbox VM and register it as a Juju cloud so that a Juju controller can be bootstrapped against it.

Steps

1. Run the setup script:

   $PROJECT_ROOT/development-sandbox/bin/setup-k8s.sh
   

   This is idempotent. Each step checks whether it has already been done. Wait for it to complete before proceeding.

2. Bootstrap a Juju controller. Use a descriptive controller name:

   juju bootstrap local-k8s k8s-ctrl
   

3. Create a working model:

   juju add-model testing
   

4. Verify the substrate is ready:

   juju status -m testing
   

Notes

• kubectl is not available directly; use sudo k8s kubectl instead.
• The kubeconfig is at /home/ubuntu/k8s.yaml. Set KUBECONFIG=/home/ubuntu/k8s.yaml if Juju commands need it explicitly.
• The local-k8s Juju cloud name is used by convention. Use it when bootstrapping.
• k8s bootstrap and wait-ready can take several minutes on first run.
