We're happy to announce the release of Lokomotive v0.8.0 (Hogwarts Express).

Changes in v0.8.0

Kubernetes updates

  • Update AKS to 1.18.17 (#1466).

Component updates

  • Update prometheus-operator to 0.46.0 (#1440).
  • Update contour to v1.13.1 (#1450).
  • Update calico to v3.18.1 (#1453).

Terraform provider updates

  • Update Terraform providers to their latest versions (#1451).

Features

  • Add a certificate rotation command: lokoctl cluster certificate rotate (#1435).
  • Add reclaim_policy field to components rook-ceph, openebs-storage-class and aws-ebs-csi-driver. Change the default behaviour of the default storage class to Retain from Delete (#1369).

Deprecation and Removal

  • Remove the webhook field from the cert-manager component (#1413).

Updating from v0.7.0

Configuration syntax changes

Reclaim Policy

This is an optional step and only applies if you use any of these storage components: rook-ceph, openebs-storage-class or aws-ebs-csi-driver.

If you are relying on the default values for the PersistentVolumes to have a reclaim policy as Delete, then please add the following field explicitly now:

reclaim_policy = "Delete"

Cluster update steps

NOTE: Updating multiple Lokomotive versions at a time is not supported. If your cluster is running a version older than v0.7.0, update to v0.7.0 first and only then proceed with the update to v0.8.0.

Execute the following steps in your cluster configuration directory:

  1. Download and install the lokoctl binary by following the v0.8.0 installation guide and verify the version using lokoctl version:
v0.8.0
  1. Download the release bundle:
curl -LO https://github.com/kinvolk/lokomotive/archive/v0.8.0.tar.gz
tar -xvzf v0.8.0.tar.gz
  1. On all platforms except AKS, update Calico CRDs:
kubectl apply -f ./lokomotive-0.8.0/assets/charts/control-plane/calico/crds/
  1. Update the control-plane:
lokoctl cluster apply -v

NOTE: If the update process gets interrupted, rerun the above command.

NOTE: If your cluster is running self-hosted kubelets, append --upgrade-kubelets to the above command.

NOTE: The command updates the cluster as well as any Lokomotive components
applied to it. Append --skip-components to the above command to avoid updating
the components. Components can then be updated individually using lokoctl component apply.

The update process typically takes about 10 minutes.
After the update, running lokoctl health should result in an output similar to the following:

Node                     Ready    Reason          Message

lokomotive-controller-0  True     KubeletReady    kubelet is posting ready status
lokomotive-1-worker-0    True     KubeletReady    kubelet is posting ready status
lokomotive-1-worker-1    True     KubeletReady    kubelet is posting ready status
lokomotive-1-worker-2    True     KubeletReady    kubelet is posting ready status
Name      Status    Message              Error

etcd-0    True      {"health":"true"}

Updating Contour

Manually update the CRDs before updating the component contour:

kubectl apply -f https://raw.githubusercontent.com/projectcontour/contour/release-1.13/examples/contour/01-crds.yaml

Update the component:

lokoctl component apply contour

Updating Prometheus Operator

Manually update the CRDs before updating the component prometheus-operator:

kubectl apply -f ./lokomotive-0.8.0/assets/charts/components/prometheus-operator/crds/

Update the component:

lokoctl component apply prometheus-operator
