Release v1.6.4

Note: This release addresses two bugs found in v1.6.3. Those fixes are available in v1.6.3 by upgrading the appropriate infrastructure stacks (Rancher Scheduler and Rancher Container Crontab). This release is primarily for users in air-gapped networks that cannot dynamically update their catalogs and must rely on the catalogs packaged in the server image.

Rancher Server Tags

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

  • rancher/server: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/server:stable tag will be our latest stable release builds. This tag is the version that we recommend for production.

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

Beta - v1.6.4 - rancher/server:latest

Stable - v1.6.4 - rancher/server:stable

Important - Upgrade

  • In this release, we will automatically upgrade the network-services infrastructure stack as without this upgrade, your release will not work.
    • Upgrading from versions prior to Rancher v1.5.0 will trigger an automatic upgrade.
    • Upgrading from versions Rancher v1.5.0+ will not trigger an automatic upgrade.
  • In this release, if you make any changes to the default Rancher library setting for your catalogs and then roll back, you will need to reset the branch used for the default Rancher library under Admin -> Settings -> Catalog.

Known Major Issues

  • Kubernetes 1.6 does not work with the native Docker version (v1.12.6) installed on RHEL. If you are running RHEL, please download upstream Docker version (v1.12.6). A fix will be made with Kubernetes 1.7, which will be released at end of July. [#9304]
  • If you are running Rancher without internet access or behind a proxy, catalog-service will panic and you will be logged out and unable to log in and default environment templates may not be present. #9378]

Major Bug Fixes since v1.6.3

  • Fixed an issue where the Rancher scheduler microservice was not closing TCP connections and consuming excessive resources [#9332] [#9306]
  • Fixed an issue where Rancher Container Crontab does not respect cron rules [#8979]
