Spring Config Server - No such label: master

Question

I have a simple Spring Cloud Config Server which consume configuration from git server.

ConfigServer bootstrap.yml :

spring:
  application:
    name: config-service
  cloud:
    config:
      server:
        git:
          uri: ssh://git@mydomain:myport/myrepo.git
          searchPaths: "configurations/{application}/{profile}"
server:
  port: 8888

When I deploy ConfigServer on local, I can retrieve configuration from http://localhost:8888/myapp/test. But when I deploy ConfigServer on test server, it throws No such label: master when I hit http://testserverip:8888/myapp/test.

Any help would be most appreciated!

Answer 1

I know that I'm posting this answer very very late. But, still posting it so that other folks can find this helpful. Now a days, default branch name of GitHub is "main", but Spring Cloud Config still looks for "master" as a label name. So, if you want to change the default behavior, you can always change the label name look up using below property in application.yml or application.properties:

spring.cloud.config.server.git.default-label=main

This worked very well for me. I'm using Spring Boot 2.3.6.RELEASE

Answer 2

GitHub created default branch "main" , however Spring cloud Config was looking for "master branch". I have created a "master" branch and it worked!

Answer 3

This happens when your service cannot access to Git repository. Since you can start your application, I assume test server can reach to Git. You should set up SSH authentication to your Git server. You can check this site for SSH configuration.

Answer 4

I faced this same annoying scenario.

I'll first state how I solved this scenario and will later emphasize my mistakes which I did in my previous approaches. In my context, I'm using application.properties

My application overview looks like below: I have a config-server which is centralized & provides the respective configuration data to the respective micro-services.

For instance, a micro-service 'limits-service', requires some configuration data, it gets it from the central configuration server('spring-cloud-config-server'). Hence to achieve this, 'limits-service' queries the central config server which in-turn fetches the requested data from a remote git branch('spring-cloud-samples').

                            ┌---------------------- <--> [currency-exchange-service]
    [git] <--> [spring-cloud-config-server] ------- <--> [limits-service] 
                            └---------------------- <--> [currency-conversion-service]

Solution:

I simply created a new Git Repository (spring-cloud-samples) for all the configuration files which would be consumed by several micro-services through a central configuration server.

In the application.properties file of central configuration server('spring-cloud-config-server'), I have provided a property as:

spring.cloud.config.server.git.uri=https://github.com/{username}/{git-reponame.git}

which might look like

spring.cloud.config.server.git.uri=https://github.com/alice123/spring-cloud-samples.git That's it!

On starting my central-config-server & observe the log which is as follows:

2020-02-17 05:25:07.867  INFO 15000 --- [nio-8888-exec-9] o.s.c.c.s.e.NativeEnvironmentRepository  : Adding property source: file:/D:/Users/{userName}/AppData/Local/Temp/config-repo-3453413414/limits-service.properties

Moreover, I also consumed the config-data through my 'limits-service' & it worked like a charm!

I tried the following things that resulted in failures and a lot of screaming & yelling. XD

I'm posting it, just so that someone who's trying this same concept might save a night's work or maybe less :p

1) Initially, I was using my Git Repositories SSH URL in my application.properties file of central-config-server like follows:

[email protected]:alice123/spring-cloud-samples.git
spring.cloud.config.server.git.username=alice123
spring.cloud.config.server.git.password=alice123Pwd

which resulted in the following error:

2020-02-17 05:22:45.091  WARN 15000 --- [nio-8888-exec-1] .c.s.e.MultipleJGitEnvironmentRepository : Error occured cloning to base directory.
org.eclipse.jgit.api.errors.TransportException: [email protected]:aniketrb-github/spring-cloud-samples.git: Auth fail

2) Later, I tried to read the config data from a native/local git directory, which was pointing to my Git remote branch(spring-cloud-samples) Then I provided the following in my application.properties file:

spring.cloud.config.server.git.uri=file://D:\aniket-workspace\github-ws\microservices\udemy-microservices\git-localconfig-repo

This crashed with:

java.lang.IllegalStateException: Failed to load property source from location 'classpath:/application.properties'

3) Later after enough googling, I changed the above property to below which worked!!:

spring.cloud.config.server.git.uri=D:\\\\alice-workspace\\\\github-ws\\\\microservices\\\\git-localconfig-repo

The 'limits-service' eventually failed while it tried to get the config-data from 'spring.cloud.config.server' with following error:

404: Not Found - "org.springframework.cloud.config.server.environment.NoSuchLabelException: No such label: master"

The solution I've stated worked for me due to all the failures I came across which I mentioned above. Please correct me if I'm wrong & improvise if necessary. I hope this helps and saves some crucial time.

Answer 5

In my case nothing of given answers worked. only thing that worked is setting default-label to master

spring.cloud.config.server.git.default-label=master

Answer 6

When you create a new repository, nowdays git makes "main" as the default branch instead of master. This issue is all about this.

Create "master" branch manually. It will solve all these issues.

Answer 7

for me this caused due to my default branch 'main'. whenever you create a new branch the default branch is 'main' not 'master' anymore. but spring server config look for master branch. the quick solution is to checkout a new branch called 'master' from 'main' branch. and try from spring config server. thats it.

to create a new branch from main branch. first point to main branch and from there

git checkout -b master git push --set-upstream origin master

restart your config server and test
