imagePullSecrets not working with Kind deployment

9/5/2018

I'm tying to create a deployment with 3 replicas, whcih will pull image from a private registry. I have stored the credentials in a secret and using the imagePullSecrets in the deployment file. Im getting below error in the deploy it.

error: error validating "private-reg-pod.yaml": error validating data: [ValidationError(Deployment.spec): unknown field "containers" in io.k8s.api.apps.v1.DeploymentSpec, ValidationError(Deployment.spec): unknown field "imagePullSecrets" in io.k8s.api.apps.v1.DeploymentSpec, ValidationError(Deployment.spec): missing required field "selector" in io.k8s.api.apps.v1.DeploymentSpec, ValidationError(Deployment.spec): missing required field "template" in io.k8s.api.apps.v1.DeploymentSpec]; if you choose to ignore these errors, turn validation off with --validate=false

Any help on this?

Below is my deployment file :

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: test-pod-deployment
  labels:
    app: test-pod
spec:
  replicas: 3
  selector:
    matchLabels:
      app: test-pod
  template:
    metadata:
      labels:
        app: test-pod
    spec:
      containers:
      - name: test-pod
    image: <private-registry>
  imagePullSecrets:
  - name: regcred

Thanks, Sundar

Please make sure you have created the secret,then please try to make it like the below .

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: test-pod-deployment
  labels:
    app: test-pod
spec:
  replicas: 3
  selector:
    matchLabels:
      app: test-pod
  template:
    metadata:
      labels:
        app: test-pod
    spec:
      containers:
       - name: test-pod
         image: nginx
      imagePullSecrets:

Very common issue with kubernetes Deployment.

The valid format for pulling image from private repository in your Kubernetes Deployment file is:

spec:
  imagePullSecrets:
  - name: <your secret name>    
  containers:
-- itmaven

Image section should be placed in container specification. ImagePullSecret should be placed in spec section so proper yaml file looks like this (please note indent):

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: test-pod-deployment
  labels:
    app: test-pod
spec:
  replicas: 3
  selector:
    matchLabels:
      app: test-pod
  template:
    metadata:
      labels:
        app: test-pod
    spec:
      containers:
       - name: test-pod
         image: <private-registry>
      imagePullSecrets:
       - name: regcred
