@cuongdnv Thanks for the question! We are investigating and will update you shortly.

@cuongdnv We can achieve this using 2 ways.

• You can give access to AKS to pull images from the ACI. Once thats done, Then in helm chart you need to provide only the ACR image url. Authentication is taken care by the role assignment.
• You need to create a secret as described here. With that secret, kubernetes will download the images. Example for creating a pull secret in helm chart is here.

You can also use azure Devops to streamline all continuous integration and deployment processes. Azure devops doc for deploying into kubernetes is here.

try this out and let me know

@cuongdnv you need to create a new helm chart for your application.
I suggest you to go through this document for more information about charts.

I am giving quick info here.
To create a chart from command line use helm create <chart name>
It will create a chart with default templates(One deployment, service and one ingress). By default that ingress will be in disabled state.

You can find many files in the chart directory. In that pick values.yaml. You need to give your image details there as shown below.
Part of the values.yaml file is here

image:
  repository: <acr name>.azurecr.io/<your repo name>
  tag: <tag name>
  pullPolicy: IfNotPresent

After adding these details, You will be able to deploy that image from ACR to AKS.
If suggest you to go through the helm quick start guide where we will be using the pre-created charts.
Once that is done then we can go for Chart creation(for advanced users).

i have trouble with helm .
yesterday i installed helm and run successfully helm chart .
But today when i back to work i can't see tiller on the server .
some command i tried
$helm version
Client: &version.Version{SemVer:"v2.14.1", GitCommit:"5270352a09c7e8b6e8c9593002a73535276507c0", GitTreeState:"clean"}
Error: could not find a ready tiller pod
then i tried to upgrade tiller:
$helm init --service-account tiller --history-max 200 --wait --upgrade
$HELM_HOME has been configured at /home/cuongndv/.helm.
Error: tiller was not found. polling deadline exceeded

I switch to another cluster and then reinstalled Helm but i can't fix it.
