Rancher Release - v2.0.7


#1

Release v2.0.7

Important

The default network selected when creating a Kubernetes cluster has been updated to canal with no network policies. With this change in default behavior, there are no network policy enforcements between projects, which means there is inter-project communication.

If you want to turn on network policies, which was the previous default behavior, then you would need to edit your cluster options to enable these network policies when deploying a cluster.

Versions

NOTE - Image Name Changes: Please note that as of v2.0.0, our images will be rancher/rancher and rancher/rancher-agent. If you are using v1.6, please continue to use rancher/server and rancher/agent.

  • rancher/rancher:v2.0.7
  • rancher/rancher-agent:v2.0.7

Rancher Server Tags

Rancher server has 2 different tags. For each major release tag, we will provide documentation for the specific version.

  • rancher/rancher:latest tag will be our latest development builds. These builds will have been validated through our CI automation framework. These releases are not meant for deployment in production.
  • rancher/rancher:stable tag will be our latest stable release builds. This tag is the version that we recommend for production.

Please do not use releases with a rc{n} suffix. These rc builds are meant for the Rancher team to test builds.

Latest - v2.0.7 - rancher/rancher:latest

Stable - v2.0.6 - rancher/rancher:stable

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.

Any upgrade after 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]
