How to ask Spring Cloud Config server to checkout configuration from specific branch?
提问by agpt
I have following Spring cloud config application.yml:
我有以下 Spring 云配置 application.yml：
spring:
application:
name: configserver
cloud:
config:
server:
git:
uri: https://[email protected]/xyz/microservices-configs.git
username: xyz
password: xyz
basedir: target/configs
server:
port: 8881
Following is my bootstrap.ymlof user microservice:
以下是我bootstrap.yml的用户微服务：
spring:
application:
name: userservice
cloud:
config:
uri: http://localhost:8881/
Scenario - 1
When I hit config server in browser like this:http://localhost:8881/development/userservice-development.yml
It serves file properly. and when I look at basediri.e. target/config, I see:
场景 - 1
当我像这样在浏览器中点击配置服务器时：http://localhost:8881/development/userservice-development.yml
它正确地提供文件。当我查看basedirie 目标/配置时，我看到：
- userservice.yml
- gateway.yml
Exactly what I wanted, Since I added this two files only in development branch.
正是我想要的，因为我只在 development 分支中添加了这两个文件。
Scenario - 2
When I run my userservice microservice project using following command:mvn clean spring-boot:run -Dspring.profiles.active=development
场景 - 2
当我使用以下命令运行我的 userservice 微服务项目时：mvn clean spring-boot:run -Dspring.profiles.active=development
It fetches the right file from git, but it checkout from master branch !but not from the development branchas I am expecting. am I expecting right ? (FYI I have both development and production yml in master branch)
它从 git 获取正确的文件，但它从 master 分支检出！但不是像我期望的那样来自开发分支。我期待对吗？（仅供参考，我在主分支中有开发和生产 yml）
So the question is, how do we go for using config server ? Is there any configuration which we can set to fetch yml from that particular branch only ? I believe we need to set some label, because as per documentation, default label is master. Can anyone let me know how do we go for setting label in above scenario ?
所以问题是，我们如何使用 config server ？是否有任何配置可以设置为仅从该特定分支获取 yml？我相信我们需要设置一些标签，因为根据文档，默认标签是 master。谁能让我知道我们如何在上述情况下设置标签？

According to the documentation, the configuration you want to set in your config client is:
根据文档，您要在配置客户端中设置的配置是：
spring.cloud.config.label=mybranch
Where mybranchis an existing branch in your git repo.
mybranch您的 git 存储库中的现有分支在哪里。

You can specify the default branch (more generally, Git label) that a config server uses if a client does not specify the label, via property spring.cloud.config.server.git.default-label, perhaps this is what you are after? Certainly solves the issue for me!
如果客户端未指定标签，spring.cloud.config.server.git.default-label您可以通过 property 指定配置服务器使用的默认分支（更一般地说，Git 标签），也许这就是您所追求的？当然可以为我解决问题！

Config server designed to use profile to separate environment. Example:
配置服务器旨在使用配置文件来分离环境。例子：
/{application}/{profile}[/{label}]
/{application}-{profile}.yml
/{label}/{application}-{profile}.yml
/{application}-{profile}.properties
/{label}/{application}-{profile}.properties
The branching make configuration inconsistency.
分支使配置不一致。
Concept of config server is based on 12-factor config (http://12factor.net/config) .
配置服务器的概念基于 12-factor config ( http://12factor.net/config)。
Check it out for detail reason.

If only use the branch in a yml file just configure:
如果只使用 yml 文件中的分支，只需配置：
spring:
cloud:
config:
server:
git:
uri: https://gitlab.com/somerepo.git
username: someuser
password: somepass
default-label: branchname
