This article introduces the relevant knowledge of "what are the new functions of Rainbond v5.2.0-beta1". In the operation of actual cases, many people will encounter such a dilemma. Then let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Version change installation and operation and maintenance

The Rainbond system installation and operation and maintenance management are reconstructed to Operator mode and run within the Kubernetes cluster.

Remove the strong dependence on Kubernetes. Rainbond no longer maintains Kubernetes cluster installation scripts. It is recommended to use easzup.

Rainbond-Operator installation uses Helm package management tools to install.

Rainbond system installation provides UI interface to control the installation progress in real time, and subsequent versions of UI provide system operation and maintenance, upgrade and other functions.

The installation provides a variety of optional configuration parameters, including key configurations such as image warehouse, database, ETCD cluster, and so on.

The life cycle of system components is jointly maintained and managed by Kubernetes and Rainbond-Operator.

In a word, if you have a Kubernetes cluster (1.13 or above), you can try the different experience that Rainbond brings.

Application Stora

Rainbond component storage abstraction supports storage types that can be extended through Kubernetes StorageClass. The storage types supported by Rainbond can be expanded by adding StorageClass in the cluster. Currently, the storage types connected to the test include Ali cloud disk, Ceph block devices and so on.

The component storage model adds capacity and mount state properties.

The appropriate storage type is selected based on the brief algorithm in the use cases such as application sharing installation and cross-cluster migration, and will be selected more intelligently based on the storage characteristics in subsequent versions.

Application gateway

The load balancing mechanism of TCP/UDP access policy is reconstructed. The update mechanism of Upstream is changed from Nginx configuration file generated in the past and modified by Reload to dynamic update controlled by Lua without triggering Reload.

HTTP access policy supports parameters such as X-Forwarded-Proto X-Scheme by default.

Proxies for public network control portals such as Rainbond data center API and console UI are added, and all requests of the cluster are uniformly entered by the gateway component.

Source code construction

The running mode of the refactoring source code build task is changed from the management node to the Kubernetes Job task, which runs on the cluster computing node, and then supports the highly concurrent build task.

Golang language Buildingpack upgrade, adding support for Go mod mode dependency package management, support for Go 1.12 1.13 # 613

Java related language Buildingpack upgrade, supporting JDK 11 12 13, Maven 3.5.4 3.6.2

PHP language Buildingpack upgrade, supporting php version 7.2.26 7.3.13

The two language types of NodeJS/NodeJS front end support UI to set construction parameters

Other changes

All system components support TLS authentication by default when communicating with ETCD.

The grctl command line changes the installation mode and adds functions such as grctl gateway grctl envoy to assist operation and maintenance.

Component supports running # 333 using privileged mode

Remove function

Remove the command line to expand the cluster node function, and easzup expands the Kubernetes cluster automatically after the Rainbond node is expanded.

Remove the automated installation of the "global shared storage" storage type (without permission to manipulate the host) and let the user install it using a simplified command line tool.

The rainbond-ansible project is for V5.1 only.
