I am creating a deployment in circlci that deploys my containerized application to a k3s server I have set up. I have set up a secret using the commands found here.

The secret is created using the command:

kubectl create secret docker-registry regkeyname --docker-server=https://index.docker.io/v1/ \
 --docker-username=username  \
 --docker-password=password  \
 --docker-email=my@email.com \
 --namespace=external

My secret is as follows when running kubectl get secret regkeyname --namespace=external --output=yaml:

apiVersion: v1
data:
  .dockerconfigjson: secretbase64stuff
kind: Secret
metadata:
  creationTimestamp: "2020-11-24T13:11:07Z"
  managedFields:
    - apiVersion: v1
      fieldsType: FieldsV1
      fieldsV1:
        f:data:
          .: {}
          f:.dockerconfigjson: {}
        f:type: {}
      manager: kubectl
      operation: Update
      time: "2020-11-24T13:11:07Z"
  name: regkeyname
  namespace: external
  resourceVersion: "16929381"
  selfLink: /api/v1/namespaces/external/secrets/regkeyname
  uid: 51b87508-9cf2-490b-b871-0b5a342ab64c
type: kubernetes.io/dockerconfigjson

I'm using helm to deploy my application and the Deployment looks like this:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: {{ .Values.labels.app }}
  labels:
    app: {{ .Values.labels.app }}
spec:
  selector:
    matchLabels:
      app: {{ .Values.labels.app }}
  replicas: 3
  strategy:
    type: RollingUpdate
    rollingUpdate:
      maxSurge: 1
      maxUnavailable: 1
  template:
    metadata:
      labels:
        app: {{ .Values.labels.app }}
        env: {{ .Values.labels.env }}
    spec:
      imagePullSecrets:
        - name: regkeyname
      containers:
        - name: my-service
          image: {{ .Values.image.repository }}:{{ .Values.image.tag }}
          imagePullPolicy: {{ .Values.image.imagePullPolicy }}
          readinessProbe:
            httpGet:
              path: /health
              port: 8080
            initialDelaySeconds: 10
            periodSeconds: 10
            failureThreshold: 5
            successThreshold: 1

after deploying however, the images fail to pull and it appears that my secret "regkeyname" is not used/mounted in the pods. the result is as follows:

I had this working when running locally with kubernetes so I am assuming the issue must have something to do either with k3s or the fact that now the server is remote rather than local. Any insight would be greatly appreciated. Thanks in advance!
