I'm using Helm v3 with AWS ECR on a Kubernetes cluster that was creating using Kops. I have checked and the role kops assigned to the nodes does have ECR permissions. When I deploy my helm chart I just get imagepullbackoff when doing kubectl get pods in the correct namespace.
Below is some of my helm chart code, I hope this is everything that's needed to debug this issue. BTW I have looked around on SO and google, both come up short on ECR with Helm and nothing for Helm 3 - was released recently.
Inside my values.yaml
image: repository: <number>.dkr.ecr.us-east-1.amazonaws.com/apigw # tag: latest tag: ef86dfe0b703 pullPolicy: IfNotPresent Note that the tag there is a git commit ID and spinnaker will change that on each deployment so here being static is just to test.
I was following this guide and as a result changed some things that might have effected it.

Main one I think that makes a difference is
imagePullPolicy: "{{ .Values.image.pullPolicy }}:{{ .Values.image.tag}}" to
imagePullPolicy: {{ .Values.image.pullPolicy }} However... If I change it back I get this error when trying to apply the helm chart
Error: Deployment.apps "apigw" is invalid: spec.template.spec.containers[0].imagePullPolicy: Unsupported value: "IfNotPresent:ef86dfe0b703": supported values: "Always", "IfNotPresent", "Never" 
imagePullSecrets, see kubernetes.io/docs/tasks/configure-pod-container/…
