Configure credentials for AWS Elastic Container Registry using registry-creds addon
The minikube registry-creds addon enables developers to setup credentials for pulling images from AWS ECR from inside their minikube cluster.
The addon automagically refreshes the service account token for the
default service account in the
- a working minikube cluster
- a container image in AWS ECR that you would like to use
- AWS access keys that can be used to pull the above image
- AWS account number of the account hosting the registry
Configuring and enabling the registry-creds addon
Configure the registry-creds addon
Configure the minikube registry-creds addon with the following command:
Note: In this tutorial, we will focus only on the AWS ECR.
minikube addons configure registry-creds
Follow the prompt and enter
y for AWS ECR. Provide the requested information. It should look like this -
$ minikube addons configure registry-creds Do you want to enable AWS Elastic Container Registry? [y/n]: y -- Enter AWS Access Key ID: <put_access_key_here> -- Enter AWS Secret Access Key: <put_secret_access_key_here> -- (Optional) Enter AWS Session Token: -- Enter AWS Region: us-west-2 -- Enter 12 digit AWS Account ID (Comma separated list): <account_number> -- (Optional) Enter ARN of AWS role to assume: Do you want to enable Google Container Registry? [y/n]: n Do you want to enable Docker Registry? [y/n]: n Do you want to enable Azure Container Registry? [y/n]: n ✅ registry-creds was successfully configured
Enable the registry-creds addon
Enable the minikube registry-creds addon with the following command:
minikube addons enable registry-creds
Create a deployment that uses an image in AWS ECR
This tutorial will use a vanilla alpine image that has been already uploaded into a repository in AWS ECR.
Let’s use this alpine deployment that is setup to use the alpine image from ECR. Make sure you update the
image field with a valid URI.
apiVersion: apps/v1 kind: Deployment metadata: name: alpine-deployment labels: app: alpine spec: replicas: 1 selector: matchLabels: app: alpine template: metadata: labels: app: alpine spec: containers: - name: alpine image: <<aws_account_number>>.dkr.ecr.<<aws_region>>.amazonaws.com/alpine:latest command: ['sh', '-c', 'echo Container is Running ; sleep 3600']
Create a file called
alpine-deployment.yaml and paste the contents above. Be sure to replace «aws_account_number» and «aws_region» with your actual account number and aws region. Then create the alpine deployment with the following command:
kubectl apply -f alpine-deployment.yaml
Test your deployment
Describe the pod and verify the image pull was successful:
kubectl describe pods << alpine-deployment-pod-name >>
You should see an event like this:
Successfully pulled image "<<account_number>>.dkr.ecr.<<aws_region>>.amazonaws.com/alpine:latest"
If you do not see that event, look at the troubleshooting section.
In the above tutorial, we configured the
registry-creds addon to refresh the credentials for AWS ECR so that we could pull private container images onto our minikube cluster. We ultimately created a deployment that used an image in a private AWS ECR repository.
- Check if you have a secret called
defaultnamespace by running
kubectl get secrets.
- Check if the image path is valid.
- Check if the registry-creds addon is enabled by using
minikube addons list.
The service account token for the
default service account in the
default namespace is kept updated by the addon. If you create your deployment in a different namespace, the image pull will not work.
