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 - v1.6.0 - rancher/server:latest

Stable - v1.5.9 - rancher/server:stable


  • HAProxy support for loading SSL certs via a data volume [#7520] - Rancher now supports the ability to the configuration of a data volume into the HAProxy LB Service where SSL certs can be read from. This is an alternative method for uploading certs into HAProxy where the certs could be constantly changing or to support multiple cert configurations.
  • Support for multiple group based searching in LDAP/AD [#8157, #8122] - Rancher now supports the ability to configure LDAP to search users and groups via different search bases.
  • Rancher EBS volume support [#8295, #8618, #7599] - Rancher EBS volume is now GA. Rancher scheduling has been enhanced to be availability zone aware so containers can be moved into hosts that are within the same availability zones. EBS has also been enabled with support for additional options such as volumetype, ios, encrypted, ksmKeyId, and snapshotId.
  • Rancher Secrets support in Compose [#8016, #8025] - Rancher now supports being able to create secrets using compose files with Rancher CLI. Please note that this feature does not exist in the older rancher-compose CLI. All new features will only be developed on the new Rancher CLI tool.
