Upgrading to 0.8.x

This guide explains how to upgrade from 0.7.x to 0.8.x.

Before you begin

Before you begin the upgrade process, ensure that you have a backup of your data.

The upgrade process will not touch the actual backup data, but will change the resource definitions and recreate the Deployments of backups.

Checklist

Follow the steps in this checklist to upgrade to 0.8.x.

Pause backups

Pause all backups to prevent any changes to the backup data by setting the .spec.enabled field to false.

Shell
Fish

#!/usr/bin/sh
for backup_name in $(kubectl get backups -n [NAMESPACE] -o custom-columns='NAME:.metadata.name' --no-headers)
do
  kubectl patch --type merge backup -n [NAMESPACE] "$backup_name" -p '{"spec":{"enabled": false}}'
done

#!/usr/bin/fish
for backup_name in (kubectl get backups -n [NAMESPACE] -o custom-columns='NAME:.metadata.name' --no-headers)
  kubectl patch --type merge backup -n [NAMESPACE] $backup_name -p '{"spec":{"enabled": false}}'
end

Replace [NAMESPACE] with the namespace where the backups are located.

Pause existing operator

Pause the existing operator by setting the .spec.replicas field to 0.

$ kubectl scale deployment kannika-operator -n kannika-system --replicas=0

This will ensure no changes are made to the existing resources while the upgrade is in progress.

Upgrade CRDs

Install the new Custom Resource Definitions (CRDs) for 0.8.x.:

Using kubectl

$ kubectl apply -f https://docs.kannika.io/refs/0.8.0/crd/kannika-crd-v1alpha.yml

Using Helm

$ helm install kannika-crd oci://quay.io/kannika/charts/kannika-crd \
  --version 0.8.0

Install application with updated Helm values

The new version of Kannika Armory adds the following options to the installation process:

API URL
API storage
OIDC authentication
Event Gateway configuration (see Backup Metrics and Restore Metrics)

Example Helm chart values that you can add to your values.yaml file:

api:
  # Add a persistent volume for the API
  storage:
    persistentVolume:
      enabled: true
      size: 10Gi
      storageClass: "default"

  # Add OIDC to the API
22 collapsed lines
  config:
    security:
      enabled: true
      oidc:
        issuerUri: "https://my-issuer-uri"
        audience: "my-audience"

console:
  config:
    apiUrl: "https://api.kannika.my-domain.com"
    security:
      # Log users out after 15 minutes of inactivity
      userInactivityTimeoutSeconds: 900
      # Add OIDC to the console
      oidc:
        enabled: true
        clientId: "my-client-id"
        audience: "my-audience"
        scope: "openid profile email"
        authEndpoint: "https://my-auth-endpoint"
        tokenEndpoint: "https://my-token-endpoint"
        logoutEndpoint: "https://my-logout-endpoint"

Install the new version of Kannika Armory using Helm:

$ helm upgrade --install kannika oci://quay.io/kannika/charts/kannika \
  --create-namespace \
  --namespace kannika-system \
  --version 0.8.0 \
  --values values.yaml

For more installation options, see Installation.

Enable backups again

Once you have completed the upgrade process, enable backups again by setting the .spec.enabled field to true.

Shell
Fish

#!/usr/bin/sh
for backup_name in $(kubectl get backups -n [NAMESPACE] -o custom-columns='NAME:.metadata.name' --no-headers)
do
  kubectl patch --type merge backup -n [NAMESPACE] "$backup_name" -p '{"spec":{"enabled": true}}'
done

#!/usr/bin/fish
for backup_name in (kubectl get backups -n [NAMESPACE] -o custom-columns='NAME:.metadata.name' --no-headers)
  kubectl patch --type merge backup -n [NAMESPACE] $backup_name -p '{"spec":{"enabled": true}}'
end

Replace [NAMESPACE] with the namespace where the backups are located.

Verify the installation

Verify that the upgrade was successful by checking the logs of the Kannika Armory components:

$ kubectl logs -n kannika-system -l app.kubernetes.io/name=kannika-operator
$ kubectl logs -n kannika-system -l app.kubernetes.io/name=kannika-api
$ kubectl logs -n kannika-system -l app.kubernetes.io/name=kannika-console

Verify that the backups are running as expected:

$ kubectl get backups -n [NAMESPACE]
