Shulou(Shulou.com)06/01 Report--

At the beginning of the first sentence, I am deeply sorry for the jumping ticket of Rancher v1.2 (bow). The way we compensate is to prove to you that Rancher v1.2 is worth the wait with the new features on this day and at this moment. Rancher, as always, adheres to the concept of 100% open source, no matter how many flattering adjectives are not as good as your download experience.

Rancher is unreserved and only wants to be used by you.

Support for Kubernetes 1.4.6

In addition to adding support for the latest upstream distribution of k8s, Rancher now provides the following support:

In addition to the default Rancher option, users can now choose AWS as the cloud provider

Added support for kubectl exec, logs, and attach

Added support for k8s node tags

Support for petset stateful application deployment

Support for upgrading k8s clusters in the environment

K8s exists as an independent Stack in Rancher UI, and Stack can be upgraded or deleted like ordinary applications.

Deployments and ReplicaSet is supported on UI

Support for Docker 1.12.x

In addition to supporting Docker 1.12.x, Rancher v1.2 has some enhancements:

Support for Docker Swarm mode,Swarm mode can now be used as an option for orchestration framework when creating an environment

Cattle now supports all Docker running options for Docker 1.12.3

Enhancement of network support: introduction of CNI

Rancher can now manage network plug-ins that meet the CNI standard

The current Rancher IPSec management network option has been completely rewritten as a CNI plug-in and can be used for Cattle and K8 orchestration frameworks

Rancher also provides VXLAN CNI plug-in, which can be used as a managed network. VXLAN network has no encryption process in cross-host communication, so its performance has been greatly improved.

Enhancements supported by Load Balancer v2

Rancher LB Service rewrites and upgrades to v2, which supports the following features:

Support SNI (Server Name Indication) routing

Support for HAProxy log viewing

Users can customize the frontend and backend configuration of HAProxy

Users can add routing rules by selecting hostname

Users can define more flexible service port mappings

Users can customize LB service instead of HAProxy

Improvements in storage support

Rancher can now manage both K8s flexvolume standard plug-ins and Docker native volume plug-ins

Cattle still supports the NFS volume plug-in. It should be noted that the new version of RancherNFS is already based on NFS Docker plugin, and the original Convoy-NFS will not be available in 1.2and will not support it after 1.3,

Rancher now supports EBS and EFS

The improvement of authentication mode

The authentication framework has been rewritten, making it more flexible to add new authentication / authorization services to Rancher

A new authentication method, Shibboleth v3, has been added to support SAML 2.0 Rancher

Improvement of general performance and scalability

The new version adds various enhancements to improve the general performance and scalability of Rancher:

The UI infrastructure view has changed to accommodate more hosts and containers in each environment

Container deployment performance has been greatly improved by improving scheduling and allowing containers to be started in parallel

Rancher CLI

Rancher now ships with a new Rancher CLI with the following support:

Interaction between native Docker CLI and managed host

Environment management

Stack management

Service management

Host management

SSH accesses your managed host

Resource scheduling

Cattle now supports scheduling based on CPU and MEM resource constraints. Admin users can set resource limits for each Host.

Environment template

Users can choose different infrastructure services to form Environment templates:

At the same time, Rancher also has a default main template, and users can quickly create Environment.

Users can also put community projects into templates to manage and deploy

HA enhancement

Rancher HA has greatly simplified management and configuration, and Redis and Zookeeper have been removed in multi-node Rancher Server deployments.

More new features, waiting for you to experience.

Rancher supports admin users to set whitelist access to Docker registries

Rancher allows administrators to set the default Docker registry

Catalog supports setting up branches of a remote git repository

Rancher agent has been rewritten based on Golang

The DockerMachine version is updated and a new Azure driver is provided.

Rancher supports deployment on RancherOS 0.6.0 +

Service Log journaling is supported, and users can better view service logs

There are many new features of Rancher v1.2, and we will continue to bring you an analysis of the overall architecture of the infrastructure engine, support for Kubernetes and Swarmkit, custom rancher-lb, support for vxlan, integration of various CNI plug-ins and practical instructions for various storage access, and so on.

Please stay tuned and join Rancher on the road to a bright container.
