Redis Backend

Spring Cloud Config Server supports Redis as a backend for configuration properties. You can enable this feature by adding a dependency to Spring Data Redis.

pom.xml

<dependencies>
	<dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-data-redis</artifactId>
	</dependency>
</dependencies>

The following configuration uses Spring Data RedisTemplate to access a Redis. We can use spring.redis.* properties to override default connection settings.

spring:
  profiles:
    active: redis
  redis:
    host: redis
    port: 16379

The properties should be stored as fields in a hash. The name of hash should be the same as spring.application.name property or conjunction of spring.application.name and spring.profiles.active[n].

HMSET sample-app server.port "8100" sample.topic.name "test" test.property1 "property1"

After running the command visible above a hash should contain the following keys with values:

HGETALL sample-app
{
  "server.port": "8100",
  "sample.topic.name": "test",
  "test.property1": "property1"
}

When no profile is specified default will be used.
