This is a dynamic configuration client for Go-Chassis which helps in configuration
management for micro-services developed using Go-Chassis sdk. The main objective of
this client is to pull or sync the configuration from config-sources for a particular
micro-service.
This Go-Archaius client supports multiple sources for the configuration.
-
Command Line Sources - You can give the configurations key and values in the command lines arguments while starting the microservice.
-
Environment Variable Sources - You can specify the sources of conifguration in Environment variable.
-
External Sources - You can also specify the configuration sources to be some external config server from where the client can pull the configuration.
-
Files Sources - You can specify some specific files from where client can read the configuration for the microservices.
You can also specify multiple sources at a same time. Go-Archaius client keeps all the sources marked with their precendence, in case if two sources have same config then source with higher precendence will be selected.
Go-Archaius client support 2 types of refresh mechanism:
- Web-Socket Based - In this client makes an web socket connection with the config server and keeps getting an events whenever any data changes.
refreshMode: 0
- Pull Configuration - In this type client keeps polling the configuration from the config server at regular intervals.
refreshMode: 1
You can configure the client to pull the configuration from external config server, the server ip address and basic parameters can be added in chassis.yaml
config:
client:
serverUri: http://XX:YYY #Config Server IP
tenantName: default #This configuration is for local environment, for paas platform there is a auth plugin for authentication. If dont provide the tenant name it will take default values.
refreshMode: 1 # 配置动态刷新模式，0为configcenter在发生变化时主动推送，1为client端周期拉取，其他值均为非法，不会去连配置中心
refreshInterval: 30 #refreshMode配置为1时，client端主动从配置中心拉取配置的周期，单位秒
autodiscovery: false
