+## Spring Cloud Kubernetes Config Server
+
+The Spring Cloud Kubernetes Config Server, is based on https://spring.io/projects/spring-cloud-config[Spring Cloud Config Server] and adds an https://docs.spring.io/spring-cloud-config/docs/current/reference/html/#_environment_repository[environment repository] for Kubernetes
+https://kubernetes.io/docs/concepts/configuration/configmap/[Config Maps] and https://kubernetes.io/docs/concepts/configuration/secret/[Secrets].
+
+This is component is completely optional.  However, it allows you to continue to leverage configuration
+you may have stored in existing environment repositories (Git, SVN, Vault, etc) with applications that you are running on Kubernetes.
+
+A default image is located on Docker Hub which will allow you to easily get a Config Server deployed on Kubernetes without building
+the code and image yourself.  However, if you need to customize the config server behavior you can easily build your own
+image from the source code on GitHub and use that.
+
+### Configuration
+
+#### Enabling The Kubernetes Environment Repository
+To enable the Kubernetes environment repository the `kubernetes` profile must be included in the list of active profiles.
+You may activate other profiles as well to use other environment repository implementations.
+
+#### Config Map and Secret PropertySources
+By default, only Config Map data will be fetched.  To enable Secrets as well you will need to set `spring.cloud.kubernetes.secrets.enableApi=true`.
+You can disable the Config Map `PropertySource` by setting `spring.cloud.kubernetes.config.enableApi=false`.
+
+#### Fetching Config Map and Secret Data From Additional Namespaces
+By default, the Kubernetes environment repository will only fetch Config Map and Secrets from the namespace in which it is deployed.
+If you want to include data from other namespaces you can set `spring.cloud.kubernetes.configserver.config-map-namespaces` and/or `spring.cloud.kubernetes.configserver.secrets-namespaces` to a comma separated
+list of namespace values.
+
+NOTE: If you set `spring.cloud.kubernetes.configserver.config-map-namespaces` and/or `spring.cloud.kubernetes.configserver.secrets-namespaces`
+you will need to include the namespace in which the Config Server is deployed in order to continue to fetch Config Map and Secret data from that namespace.
+
+#### Kubernetes Access Controls
+The Kubernetes Config Server uses the Kubernetes API server to fetch Config Map and Secret data.  In order for it to do that
+it needs ability to `get` and `list` Config Map and Secrets (depending on what you enable/disable).
+
+### Deployment Yaml
+
+Below is a sample deployment, service and permissions configuration you can use to deploy a basic Config Server to Kubernetes.
