Deployment is fails to create Pods

[gkarthiks]

Deployment is failing to create Containers / Pods.

I am trying to deploy the kafka and kubeless into our cluster. All other objects posted to k8s are created successfully, but Deployment config alone is not completing successfully. Instead it is creating an empty deployment and no containers or pods are created via Deployment.

In the Web Console I could see the following.

But under the deployments,

If I execute the oc get deploy command,

NAME	DESIRED	CURRENT	UP-TO-DATE	AVAILABLE	AGE
kafka-trigger-controller	1	0	0	0	25m
kubeless-controller-manager	1	0	0	0	28m

Version

oc version command result,

oc v1.5.1+7b451fc
 kubernetes v1.5.2+43a9be4
 features: Basic-Auth

 Server <Internal-Cluster>
 openshift v3.7.9
 kubernetes v1.7.6

Steps To Reproduce

1. Deploy kubeless v0.5.0 via oc create -f https://github.com/kubeless/kubeless/releases/download/v0.5.0/kubeless-openshift-v0.5.0.yaml
   or
   Deploy kafka via oc create -f https://github.com/kubeless/kubeless/releases/download/v0.5.0/kafka-zookeeper-v0.5.0.yaml

Current Result

No containers are created from the deployment object.

Expected Result

Deployment should create the containers/pods defined in the Deployment config.

Additional Information

@gkarthiks please provide also the output of oc get deploy,rs,po -o yaml and oc get events -o yaml

@tnozicka Have attached the results of the deployments and events.
FYI, I tried to redeploying just the kafka and zookeeper sts again by deleting it. Still no good.

In the dump you have sent all seems fine:

- apiVersion: extensions/v1beta1
  kind: Deployment
  metadata:
    name: kubeless-controller-manager
    namespace: kubeless
  spec:
    replicas: 1
  status:
    availableReplicas: 1
    readyReplicas: 1
    replicas: 1
    updatedReplicas: 1

apiVersion: v1
items:
- apiVersion: extensions/v1beta1
  kind: Deployment
  metadata:
    name: kafka-trigger-controller
    namespace: kubeless

    replicas: 1
  status:
    availableReplicas: 1
    observedGeneration: 1
    readyReplicas: 1
    replicas: 1
    updatedReplicas: 1

I even see the RS and Pods running for those Deployments. The old events are already gone.
