Kubernetes PropertySource order

What is the order of Kubernetes PropertySource with respect to the application's application.yml/bootstrap.yml files and config service? This should be documented in the README.

Add a more real Test case to demonstrate/test configMap

Add a Java Junit Test case containing a SpringBoot application exposing a HTTP APi where the message is found from the Kubernetes ConfigMap deployed within a KubernetesMock Server

Use auto-configuration in discovery

In combination with KubernetesDiscoveryClientConfiguration to allow use of @ConditionalOn*Bean

See spring-cloud/spring-cloud-netflix@5b25c9a

Too many hibernate debug messages are logged

When the Arquillian Integration Test is executed, hundred of lines are reported with DEBUG level about Hibernate Validator

mvn clean install -Pintegration

This problem can be solved by adding within the logback.xml file the info level for hibernate validator

remove fabric8 references

This error occurs both locally and on kubernetes.

How does the PropertySource reload work for HA config server?

Reference to https://github.com/spring-cloud-incubator/spring-cloud-kubernetes#propertysource-reload

Git can send notification to a URL but we want to have multiple config servers for high-availability. One option is to put them in a K8S service but then we need to build something in K8S to send notifications to all pods in the service.

Standardize on commons logging interfaces

Spring standard

Update to spring cloud style documentation

move config to separate module

Update to Dalston

from Brixton

Setup mvnw for building

Update to spring style version numbers

Start with 0.2.0 since original was 0.1

Move to 1.0.0 when the project graduates from spring-cloud-incubator

Setup KubernetesMockServer before to bootstrap springboot test

I have developed a test case in order to check if the key to be used to populate the response message of the rest controller is coming from a Kubernetes ConfigMap which has been created using a MockServer

Here is the code of the class : https://github.com/cmoulliard/spring-cloud-kubernetes/blob/java-testcase/spring-cloud-kubernetes-config/src/test/java/org/springframework/cloud/kubernetes/config/ConfigMapsSpringBootTest.java

Is there a trick that I could use to bootStrap the SpringBoot application after the MockServer has been created & configMap populated ? Otherwise, the test will continue to validate the by default value of the Greeting class which is Hello, World! and not Hello ConfigMap, World!

Add origination of code

We should give mention of where this came from and give credit where credit is due.

Use NodePort instead of ClusterIP

Use NodePort instead of ClusterIP to allow to access from the host the service running within the pod

With this change, we can access the service using IP address returned by this command to make a curl request

minikube service kubernetes-hello-world

Use circle CI for PR builds

Add .editorconfig

This will help having a consistent format, effortless for all IDEs.
It will also help reviewing too.

remove InetUtils class

and the whole spring-cloud-kubernetes-compat module

Make java 7 compatible

Update to spring cloud depencencies model

Create a spring-cloud-kubernetes-dependencies module

Remove com.google.guava if possible

Move from @Value for properties defaults to allow relaxed binding for defaults

@value("${spring.application.name:unknown}")

Upgrade to Camden dependencies

Since this is the current release, we could release 0.X.X releases against the camden dependencies.

See #18

Don't reference the release train directly

When the project joins the train, that would be a circular dependency.

Purpose of the README

Support Updating Metadata in KubernetesServiceInstance

Currently getMetadata() in KubernetesServiceInstance returns

Collections.EMPTY_MAP

But other libraries like the axon-distributed-commandbus-springcloud use Metadata to store information like load factor. (SpringCloudCommandRouter.java)

It would be great if there would be some kind of support for those use cases.

References to the "iPaas Quickstarts - Spring Boot - Ribbon" project should be updated

The links to the iPaas Quickstarts - Spring Boot - Ribbon are invalid now.
They should be updated to the fabric8-quickstarts/spring-boot-ribbon project I believe.

Add to spring jenkins for CI and snapshot publishing

publish to repo.spring.io

Make spring-boot-actuator optional

Update parent to spring-cloud-build

move off of fabric8-maven-plugin

Service name is too long for the Spring Cloud Kubernetes Reload example

When the Service resource yaml is generated for the Spring Cloud Kubernetes Reload example using f-m-p and deployed on Kubernetes (using minikube)

mvn clean package fabric8:deploy -Pkubernetes -Dfabric8.generator.from=fabric8/java-alpine-openjdk8-jdk:1.2.3
...

This error is reported

[ERROR] Failed to execute goal io.fabric8:fabric8-maven-plugin:3.2.28:deploy (default-cli) on project spring-cloud-kubernetes-reload: Failed to create Service from kubernetes.yml. io.fabric8.kubernetes.client.KubernetesClientException: Failure executing: POST at: https://192.168.99.100:8443/api/v1/namespaces/default/services. Message: Service "spring-cloud-kubernetes-" is invalid: metadata.name: Invalid value: "spring-cloud-kubernetes-": must match the regex [a-z]([-a-z0-9]*[a-z0-9])? (e.g. 'my-name' or 'abc-123').

as the Service name has been truncated by fmp as it is longer as 24 chars

The workaround is to define a shorter name and pass it within the tag of the fmp configuration

<configuration>
              <enricher>
                <config>
                  <fmp-service>

                </config>
              </enricher>
</configuration>

Such a modification must be done for the Deployment resource too

message: Deployment.extensions "spring-cloud-kubernetes-" is invalid: metadata.name: Invalid value: "spring-cloud-kubernetes-": must match the regex [a-z0-9]([-a-z0-9]*[a-z0-9])?(\.[a-z0-9]([-a-z0-9]*[a-z0-9])?)* (e.g. 'example.com').

Check if we want to keep sundrio for generating the bom

Add K8S Discovery watch

There is a gap with spring-cloud-consul-discovery regarding refresh feature. Spring Cloud Consul Discovery is providing a CatalogWatchDog which is firing HeartBeatEvent instances so listeners can refresh the list of services in case it has been changed.

Use kubernetes, why still need spring cloud?

I hope everyone give me your suggestion, thank you.

Document relationship between s-c-kubernetes, kubernetes client, kubenetes model & API

As spring-cloud-kubernetesuses librairies released by the Fabric8 project, that should be great to include within the documentation a table describing How this project is aligned with the Kubernetes API (1.3, 1.4, 1.5, ...) through the Fabric8 Kubernetes Client (= 1.x or 2.x) and Fabric8 Kubernetes Model (= 1.0.x)

Describe how to do integration tests with Kubernetes

/cc @iocanel

Perform a 0.2.0.RELEASE

Hi,

Sorry if I miss it, but I want to use Spring cloud Kubernetes and I didn't find any information on how to integrate it.

The doc said to add it as dependency to my pom.xml, but the code example use a variable as version ${latest.version (with a missing bracket).
I don't find it in maven central or mvn repository. I only have the old one under the groupId io.fabric8

I will use the io.fabric8 version 0.1.4 as a fallback but I would like to switch to this version 😄

Thanks
