Configuration files used in http://blog.kubernetes.io/2016/12/cluster-federation-in-kubernetes-1.5.html blog post.

Before you start update scripts/0-settings.sh with your project name, domain. Then run:

. scripts/0-settings.sh

You can skip this step. Images are already deployed to Docker Hub repository

make push

1. make sure you have gcloud utility

2. create cluster

   . scripts/1-create.sh
   

3. make sure kubefed and kubectl are in $PATH

4. initialize kubectl config

   . scripts/2-getcredentials.sh
   

5. initialize federation

   . scripts/3-initfed.sh
   

6. join clusters to federation plane

   . scripts/4-joinfed.sh
   

7. create an SSL certificate for your ingress host (foo.bar.com is fine for this example)

   openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout /tmp/tls.key -out /tmp/tls.crt -subj "/CN=foo.bar.com"
   

8. deploy secret, service, ingress and replica set

   kubectl --context=federation create secret tls ing-secret --key /tmp/tls.key --cert /tmp/tls.crt
   kubectl --context=federation create -f services/k8shserver.yaml
   kubectl --context=federation create -f ingress/k8shserver.yaml
   kubectl --context=federation create -f rs/k8shserver.yaml
   

9. query the service. It may take a few minutes for ingress to allocate the IP.

   kubectl --context=federation get ing
   NAME         HOSTS     ADDRESS         PORTS     AGE
   k8shserver   *         130.211.19.38   80, 443   1m
