Rancher v1.2, the latest version of Rancher, has been fully released, and in addition to the necessary support for the latest versions of Kubernetes, Docker and Docker Compose, this upgrade includes major feature enhancements to the Rancher container management platform itself.

Rancher v1.2 fully supports the latest storage and networking plug-in frameworks (described in more detail below) and provides new simplified HA settings, a more flexible Rancher HAProxy Load Balancer, and a new Rancher CLI. We've also added SAML 2.0 support, resource scheduling, and many improvements for performance and scalability. Rancher v1.2 is a big upgrade, and the new features are listed in Release Note, but there are some that we especially want to highlight for you.

Full support for container networking and storage plug-in frameworks

Last year Docker introduced Docker Volume plugins and libnetwork, while Kubernetes opted for Container Network Interface (CNI) and FlexVolume frameworks. Since then, we've seen an explosion of container ecosystems, all of which allow users to take advantage of today's storage and networking solutions.

One of the highlights of Rancher is that it allows users to freely choose which tools to use in different infrastructures. With the release of v1.2, Rancher fully supports CNI, allowing users to use CNI network plug-ins from any vendor in cross-host networks, as well as our own rewritten IPSec and VXLAN solutions. Users can also create volumes using any Docker Volume plug-in for containers, stacks, or environments. Rancher v1.2 comes with plug-ins that support NFS (which replaces Convoy NFS), AWS EFS, and AWS EBS overrides.

Modular, button, container-ready environment

In addition to providing distribution and lifecycle management capabilities for storage and network plug-ins, we introduced the concept of custom environment templates in Rancher v1.2. Network and storage plug-ins can now be combined as options in customizable templates, which also include options for orchestration engines, external DNS, and health checks. This enables users to better organize and manage services and provides direct, consistent, and repeatable deployment of infrastructure services. In the future, we want to expand the scope of the environment template to include additional Infrastructure services such as logging, monitoring, and databases.

Faster and more frequent new releases

When Rancher launched v1.0 earlier this year, our goal was to deliver stable releases every quarter, with biweekly pre-release snapshots for the Rancher open source community that wanted to experience the latest features. However, key components in Docker and Kubernetes adhere to different release schedules, and our open source community needs more frequent and stable releases. So we decided to start with v1.3 and we will release stable versions of Rancher monthly.

This means that we will no longer release pre-releases as we have done before, but release candidates will still be available for download and testing. We hope that this new release schedule will increase our flexibility to release new features, keep up with Docker and Kubernetes updates, and shorten the time between stable releases for Rancher users who want to experience new features and bug fixes quickly.
