Release v2.1.3

Important

This release updates to the latest Kubernetes versions (i.e. v1.10.11, v1.11.5, v1.12.3) for clusters launched by Rancher to address Kubernetes CVE-2018-1002105. We recommend upgrading your Kubernetes clusters to these versions.

With this release, the following versions are now latest and stable:

Type Rancher Version Docker Tag Helm Repo Helm Chart Version
Latest v2.1.3 rancher/rancher:latest server-charts/latest 2018.12.1
Stable v2.1.3 rancher/rancher:stable server-charts/stable 2018.12.1

Known Major Issues

  • Clusters created through Rancher can sometimes get stuck in provisioning [#15970] [#15969] [#15695]
  • The upgrade for Rancher node-agent daemonset can sometimes get stuck due to pod removal failure on a Kubernetes side [#16722]

Major Bug Fixes since v2.1.2

Tools

Upgrades and Rollbacks

Rancher supports both upgrade and rollback starting with v2.0.2. Please note the version you would like to upgrade or rollback to change the Rancher version.

Due to the HA improvements introduced in the v2.1.0 release, the Rancher helm chart is the only supported method for installing or upgrading Rancher. Please use the Rancher helm chart to install HA Rancher. For details, see the HA Install - Installation Outline.

If you are currently using the RKE add-on install method, see Migrating from a RKE add-on install for details on how to move to using a helm chart.

Any upgrade from a version prior to v2.0.3, when scaling up workloads, new pods will be created [#14136] - In order to update scheduling rules for workloads [#13527], a new field was added to all workloads on update, which will cause any pods in workloads from previous versions to re-create.

Note: When rolling back, we are expecting you to rollback to the state at the time of your upgrade. Any changes post upgrade would not be reflected. In the case of rolling back using a Rancher single-node install, you must specify the exact version you want to change the Rancher version to, rather than using the default :latest tag.

Note: If you had the helm stable catalog enabled in v2.0.0, we’ve updated the catalog to start pointing directly to the Kubernetes helm repo instead of an internal repo. Please delete the custom catalog that is now showing up and re-enable the helm stable. [#13582]
