Rancher Release - v1.2.2

Release v1.2.2


Note: With our new infrastructure services, we no longer launch a network agent and have moved to a specific HAProxy image for load balancers. Therefore, we no longer need rancher/agent-instance.


  • Starting with version 1.2.0, Rancher no longer supports AWS ELBs and only supports AWS ALB (Application Load Balancers). Please update your high availability setups to use ALBs.
  • When upgrading from prior v1.2.x releases, please check your infrastructure stacks to make sure your services are up to date. If an “Upgrade Available” button is shown, please update to the latest service.
  • If you are upgrading from 1.1.x to v1.2.2, please read the v1.2.0 release notes on important notes about the upgrade.
