This article mainly introduces how to add custom nodes in Rancher 2.0. it is very detailed and has a certain reference value. Friends who are interested must read it!

Rancher is an open source full-stack enterprise container management platform. Users can complete the docking and deployment of all container infrastructure (network, storage, load balancing, etc.) with one click on the Rancher visual interface, ensuring that containers run seamlessly on any infrastructure (public or private cloud, virtual machine, physical machine, etc.). All the work of using containers in the production environment can be done by simple and intuitive operation.

Starting with Rancher 2.0, each cluster in Rancher will be based on Kubernetes. Users can take full advantage of the powerful performance of Kubernetes and its fast-growing ecosystem, and Rancher 2.0 will accelerate the popularity of Kubernetes in the enterprise through the simple and intuitive user experience based on Kubernetes on the Rancher platform.

Rancher Labs released the first technical preview version of Rancher 2.0 at Container Day, the annual user conference of Rancher China, on September 27th, 2017, and received a great positive response from a large number of enterprise customers and countless users in the open source community. Over the past quarter, the Rancher Labs R & D team has continuously updated and optimized the architecture and functionality of Rancher 2.0 based on a large amount of feedback, and officially released the technical preview version of Rancher 2.0 II on January 24th. Today, Rancher 2.0 is a milestone update, and users can add custom nodes when creating RKE clusters!

1. Unified management of K8s clusters from different infrastructures as more and more cloud service providers begin to provide K8s cluster services, it is no longer necessary for users to create their own clusters. Rancher 2.0 enables users to uniformly manage existing K8s clusters from across infrastructures, whether from a cloud service provider (such as Google GKE) or a local data center.

2. Multi-cluster management

Rancher 2.0 provides centralized management of user authentication, monitoring, and health checks, and IT administrators have greater visibility and control. Rancher 2.0 makes full use of the complex role-based access control (RBAC) function of K8s to provide users with shared cluster and host access.

3. Excellent user experience

Rancher's already excellent user experience has been significantly improved again, making the Kubernetes experience on the Rancher platform as simple as the Docker command line and as elegant as Docker Compose, solving the historical problem of poor ease of use of Kubernetes native UI.

4. Rich application directory

Rancher's Enterprise Application Service Catalog (Catalog) has been expanded to support Docker Compose, Kubernetes templates, and Helm charts, allowing users to access more containerized applications.

5. Milestone update: support adding custom nodes

The previous version of this update only supports DigitalOcean and AWS, but in the latest version, users can add custom nodes when creating a RKE cluster. Custom nodes can be added through SSH / IP or docker run:

● uses SSH / IP: the user provides the node's IP and SSH keys, and Rancher uses the SSH key to create a secure SSH tunnel for the node's docker daemon. After a successful connection, Rancher installs the corresponding K8s components for the node in the manner indicated by the user-specified role.

● will generate docker run commands that can be executed on each node through docker run:Rancher, and will install the corresponding K8s components according to the role you choose for the node.

The simple and intuitive interface style and operation experience of Rancher 2.0 solves the long-standing problems of poor ease of use of Kubernetes native UI and steep learning curve. The creative multi-Kubernetes cluster management function of Rancher 2.0 also perfectly solves the different infrastructure dilemmas that enterprise users may face in the production environment. At the same time, Rancher 2.0 also brings a series of extended functions. It can be said that Rancher 2.0 provides a more convenient way for enterprises to land Kubernetes in the production environment and to build a new generation of Container as a Service.
