Description Michael Nguyen 2016-03-31 18:04:33 UTC 
Document
------------------- 
Name: RED HAT ENTERPRISE LINUX ATOMIC HOST 7 GETTING STARTED WITH CONTAINERS
URL: https://access.redhat.com/documentation/en/red-hat-enterprise-linux-atomic-host/version-7/getting-started-with-containers/

The kubernetes db-service is unable to find the pods deployed by the replication controller because the db-service.yaml file has an incorrect selector.  The selector should be "app: db" instead of "name: db" (see below for the correct file content)

db-service.yaml 
-------------------

apiVersion: v1
kind: Service
metadata:
  labels:
    name: db
  name: db-service
  namespace: default
spec:
  ports:
  - port: 3306
  selector:
    app: db


db-service.yaml is referenced in section "2.3.3 Launching container pods with Kubernetes" and "3.7. LAUNCHING SERVICES, REPLICATION CONTROLLERS, AND CONTAINER PODS WITH KUBERNETES".  It is also included in kube_files.tar which is linked on the site.

There are inconsistencies between the contents of the yaml files displayed in the documentation and kube_files.tar.  They should be identical.

I changed name: db to app: db in the document, as described earlier.  Once published, the fix can be found here: https://access.redhat.com/documentation/en/red-hat-enterprise-linux-atomic-host/version-7/getting-started-with-containers/#get_started_orchestrating_containers_with_kubernetes
Comment 3 Vikram Goyal 2016-06-09 07:03:19 UTC 
Thanks Chris. This fix can be verified in section 3.3.3 here [1].

Moving this bug to CLOSED-->CURRENTRELEASE.
