Create a Container Instance using an Image from Docker Hub

Question

Create a Container Instance using an Image from Docker Hub

LIGEngelsen 45

When I try creating a Container Instance using an image from "Other registry", I get the following error message:

An error response is received from the docker registry 'docker.io'. Please retry later.

Others in the Docker community have observed the same outcome:

What do I need to do, to create the container using a DockerHub image?

Hi,

Based on the error you are most likely running into the Docker Hub per IP address per 6 hour limit of 100. Multiple different Azure tenants are using same IP addresses for pulls, so you can see how easy it is to reach 100 and then everyone afterwards is blocked for that IP for the rest of the 6 hour time block. Screenshot from usage limit page:

User's image

You should be able to work around this by authenticating using your Docker account, or failing that, you could do docker pull to your local machine and push it to your Azure Container Registry. Your local PC's public IP address likely hasn't reached the 100 limit so even unauthenticated should work.

In case you aren't already familiar with the process, please see article below for walkthrough of pulling a public image and then pushing it to ACR.

Push your first image to your Azure container registry using the Docker CLI

https://learn.microsoft.com/en-us/azure/container-registry/container-registry-get-started-docker-cli?tabs=azure-cli

Once you have the image in your ACR you can specify that instead of using public Docker Hub. If you run into any issues please add a comment below.

Do you have a resource that explains how to "authenticate using your Docker account" at the time of Container Instance creation?

Here's what I've already tried:

Create a container instance using the azuredocs/aci-helloworld:latest image.

Connect to the container.

Run the docker login -u username_here command

However, but the docker command was not recognized.

I meant by selecting Image type: Private and then filling in your creds on Basics tab:

That worked!

Here are the commands that I needed to run on my local computer:

docker login docker pull logzio/logzio-api-fetcher:latest docker tag logzio-api-fetcher DOCKER_USERNAME_HERE/logzio-api-fetcher docker push DOCKER_USERNAME_HERE/logzio-api-fetcher

When creating the Container Instance (in Azure) I set the "Image Type" to Private.
Image: DOCKER_USERNAME_HERE/logzio-api-fetcher

Image registry login server: index.docker.io

Image registry user name: DOCKER_USERNAME_HERE
Image registry password: READ_ONLY_ACCESS_TOKEN_HERE

Access tokens can be created here: https://app.docker.com/settings/personal-access-tokens
