Kyma 1.23 Dhahran

Klaudia Grzondziel, Technical Writer @Kyma on June 2, 2021

Marhaba! مرحبا ! While we're staying in the Middle East, we are still moving forward, this time having a short stop in Dhahran, Saudi Arabia. With our eyes set on the horizon and focused on delivering Kyma 2.0, we still keep providing regular improvements, this time for Serverless, Loki, and Service Mesh. So imagine you're with us in Dhahran, sitting under one of the palm trees, and read on to learn more about the recent changes.

CAUTION: In this release, the Loki volume size was increased. Before upgrading to 1.23, read the Migration Guide for details about the upgrade process.

See the overview of all changes in this release:

As we announced some time ago, we removed Node.js 10 from the list of supported runtimes for Functions. At the same time, we introduced a new runtime, Node.js 14, and set it as the default one. From now on, you can create Functions using:

  • Node.js 12
  • Node.js 14
  • Python 3.8

We also updated Kyma CLI to reflect the new runtime changes. Kyma CLI 1.23 now sets Node.js 14 as the default runtime for your Functions. If you update Kyma CLI without updating Kyma, you will face an incompatibility when initiating Functions with Kyma CLI. To resolve it, override the runtime version with the --runtime flag.

We increased the persistence for Loki from 1 to 5 days. To accommodate this change, we also increased the default volume size of PersistentVolumeClaim for Loki from 10Gi to 30Gi. Read the Migration Guide to learn more about the upgrade process.

With this release, we upgraded Istio to version 1.9.5. This upgrade fixes several security vulnerabilities and a few minor issues. See Istio 1.9.5 release announcements for more information.

We decided to deprecate Service Catalog and all the related components, and in the nearest future, we are going to completely remove them. The main reason for this decision is the fact that hyperscale cloud providers no longer support the Open Service Broker API for service provisioning. Instead, they switched to operators, and we will also follow this approach in Kyma Service Management. Here you can learn more about operators for three main cloud providers:

Furthermore, the following components have been impacted by this decision and are therefore deprecated together with Service Catalog:

  • Helm Broker
  • Application Broker
  • Service Binding Usage Controller
  • Rafter

The details and the migration guides related to the deprecation will be announced later.

The ipaddress module of the Python standard library suffers from the IP address validation vulnerability (CVE-2021-29921). Up to the date of Kyma 1.23 release, there is no security patch for Python 3.8.x. We will track the vulnerability and issue a patch release for Kyma as soon as the fix is available.

It is rather uncommon to pass IPv4 addresses with leading zeros, but if you want to tolerate leading zeros in your Serverless Python-based Functions, you can pre-process your inputs as described in the workaround.
