The following column will introduce you to Nacos’s method of solving laravel configuration switching in multiple environments from the Laravel Tutorial column. I hope it will be helpful to friends in need!
For the environment in which the application runs, it is often useful to have different configurations for different environments. For example, you may want to use a different cache driver locally than the one used by the production server.
.env The configuration cannot distinguish between multiple environments (development, testing, production).env Configuration sharing is too troublesome (team LAN environment)Configuration cannot be managed in real time, configuration additions, deletions and modifications
Automated deployment configuration The .env file is too cumbersome
Nacos is Alibaba’s latest open source project. Its core positioning is “an easier-to-use Help build a dynamic service discovery, configuration and service management platform for cloud native applications", project address: nacos.io/zh-cn/
Mainly used here The configuration management of Nacos is done, and functions such as dynamic services are not used. The principle is also very simple, directly modify the .env file through the interface. The Nacos service can be directly used using the Application Configuration Management provided by Alibaba Cloud, without installation. The link is as follows: acmnext.console.aliyun.com/

.env.example Forgetting to add configuration items, shared configuration is not a trouble, and automatic deployment is not Frequent configuration changes are required.
