How to create an Azure Container Instance using Docker image

Question

Good morning,

I want to know how to create an Azure Container Instance using a custom template that use a docker repository.

Since yesterday I have created ACI using a public repository but now I need to create again this ACI and I encounter this error: An error response is received from the docker registry 'index.docker.io'. Please retry later.

How could I solve this problem?

Thanks in advance

Hi nicola,

Welcome to the Microsoft Q&A Platform! Thank you for asking your question here.The error might be a temporary issue with Docker Hub, waiting a few minutes and retrying might resolve it. please retry once again.Please verify that the repository name is correct and accessible publicly.

The most common cause of the error is rate limiting by Docker Hub. Ensure that you're not hitting the rate limit for unauthenticated requests. You can refer to this document for more information regarding rate limits and how to check it https://docs.docker.com/docker-hub/download-rate-limit/

If you're using a custom template, ensure its correctly structured for a public Docker repository and deploy the template via CLI: For example

resources:
- name: myaci
  type: Microsoft.ContainerInstance/containerGroups
  apiVersion: '2021-07-01'
  location: <location>
  properties:
    containers:
    - name: nginx
      properties:
        image: nginx:latest
        resources:
          requests:
            cpu: 1
            memoryInGB: 1.5
        ports:
        - port: 80
    osType: Linux
    ipAddress:
      type: Public
      ports:
      - protocol: tcp
        port: 80
