title: Gitlab CI Pipeline: Cannot create pods in the namespace
body: <p>I have a kubernetes cluster (rancherOS &amp; RKE) that has a running gitlab runner pod.
  Connection to my GitLab instance works fine.</p>
  
  <p>If I activate the pipeline, it directly fails with this error:</p>
  
  <pre><code>Running with gitlab-runner 11.4.2 (cf91d5e1)
    on Kubernetes Runner e5e25776
  Using Kubernetes namespace: gitlab-managed-apps
  Using Kubernetes executor with image ubuntu:latest ...
  ERROR: Job failed (system failure): pods is forbidden: User "system:serviceaccount:gitlab-managed-apps:default" cannot create pods in the namespace "gitlab-managed-apps"
  </code></pre>
  
  <p>This here is my gitlab-runner deployment yaml:</p>
  
  <pre><code>apiVersion: extensions/v1beta1
  kind: Deployment
  metadata:
    name: gitlab-runner
    namespace: gitlab-managed-apps
  spec:
    replicas: 1
    selector:
      matchLabels:
        name: gitlab-runner
    template:
      metadata:
        labels:
          name: gitlab-runner
      spec:
        containers:
        - args:
          - run
          image: gitlab/gitlab-runner:latest
          imagePullPolicy: Always
          name: gitlab-runner
          securityContext:
            privileged: true
          volumeMounts:
          - mountPath: /etc/gitlab-runner
            name: config
          - mountPath: /etc/ssl/certs
            name: cacerts
            readOnly: true
        restartPolicy: Always
        volumes:
        - configMap:
            name: gitlab-runner
          name: config
        - hostPath:
            path: /usr/share/ca-certificates/mozilla
          name: cacerts
        hostNetwork: true
  </code></pre>
  
  <p>I tried to add a security context with the parameter "privileged: true" but that does not help..</p>
  
  <p>Has anyone an idea on how to grant the gitlab-runner deployment the right permission to create other pods in the namespace "gitlab-managed-apps"?</p>
  
  <p>Thanks a lot :)</p>
