toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading

If you run docker pull on the machine once, on subsequent times your Dockerfile is run, it will use the local copy instead of hitting Docker Hub (and using up your rate limit). So for me, I ran this command one time:

docker pull ubuntu:18.04

… and subsequent times it worked fine.

Alternatively, switching to the AWS public Docker repository by switching my Dockerfile from:

FROM ubuntu:18.04

to

FROM public.ecr.aws/lts/ubuntu:latest

also worked for me.

If Amazon ECR Public Gallery does not offer the desired image copying the image from Docker Hub to a private ECR registry could also be an option.

Skopeo for example can do this. This snippet synchronizes your private registry with Docker Hub:

skopeo sync --dest-creds AWS:$(aws ecr get-login-password --output text) --src docker --dest docker docker.io/library/nginx <YourAWSAccountId>.dkr.ecr.eu-central-1.amazonaws.com/

One solution is that you should login docker hub by below command:

$ sudo docker login --username=yourUsername

More Help About Login Docker

In my case, there was NO issue with Docker login.
I was able to download docker images with docker pull nginx.
However when I was trying to create a k8s pod with the above image, I was getting this error:

you have reached your pull rate limit. You may increase the limit by authenticating and upgrading

This is how I managed to fix this issue by creating a private docker registry :

create and run a private docker registry

docker run -d -p 5000:5000 --restart=always --name registry registry:2

download nginx image from public docker hub

docker pull nginx

create a tag for nginx before pushing it to private registry

docker tag nginx localhost:5000/nginx

Push to registry

docker push localhost:5000/nginx

And finally created a Pod successfully and also got rid of this issue.

If you’re pulling a public image from docker then you can push it to your own public ECR repository too.

1. Create a new public ECR repository.
2. Login to ECR

aws ecr-public get-login-password --region us-east-1 | docker login --username AWS --password-stdin public.ecr.aws

3. Pull docker image e.g., amazoncorretto:11-alpine

docker pull amazoncorretto:11-alpine

4. List docker images

docker images

REPOSITORY                                                         TAG             IMAGE ID       CREATED         SIZE
amazoncorretto                                                     11-alpine       e9ae3c220b23   7 weeks ago     325MB

5. Take IMAGE ID and push the image to ECR

docker tag e9ae3c220b23 public.ecr.aws/registry_alias/my-web-app
docker push public.ecr.aws/registry_alias/my-web-app

6. Then update your Dockerfile to build FROM public.ecr.aws/registry_alias/my-web-app instead of FROM amazoncorretto:11-alpine

You can either pay to get more attempts or you can use other alternatives like quay.io, for example I got this from command below:

$ docker pull minio/console
Using default tag: latest
Error response from daemon: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit

Then I decided to use quay.io and I got my image:

$ docker pull quay.io/minio/console:v0.18.1
v0.18.1: Pulling from minio/console
54e56e6f8572: Pull complete 
4f8ddd7f5a75: Pull complete

Status: Downloaded newer image for quay.io/minio/console:v0.18.1

Why?

You get this error when you try to pull an image from the public Docker Hub repository after you have reached your Docker pull rate limit. Docker Hub uses IP addresses to authenticate the users, and pull rates limits are based on individual IP addresses.

• For anonymous users, the rate limit is set to 100 pulls per 6 hours per IP address.
• For authenticated users with a Docker ID, the pull rate is set to 200 pulls per 6-hour period.
• If your image pull request exceeds these limits, these requests are denied until the six-hour window elapses.

Every docker pull command execution counts against your quota regardless if the requested image is up to date or not. Hitting the request limit is a piece of cake if you deploy your application stack to a cluster.

Solutions:

1. Use Amazon ECR public registry for public container images

You can avoid reaching the Docker Hub’s rate limit by pulling images from the Amazon ECR public registry.
The Amazon ECR public registry contains popular base images, including operating systems, AWS-published image.

For E.g.

FROM public.ecr.aws/lts/ubuntu:latest

2. Subscribe to Docker Hub

This will allow you to increase the pull limit for authenticated users and make it unlimited for anonymous ones. If you are an individual or a small team of 2-10 people who just need a space to store images, then paying $5 to $7/month per user is the simplest solution.

3. Mirror Images to Your Own Registry

Mirroring or copying images from Docker Hub to your own registry might seem like overkill at first glance. However, it has two major benefits for security and governance and is considered a best practice, especially for using containers in an enterprise context.

4. Proxy to Docker Hub

The third option is pretty similar to option #2 but there are no replication rules needed. Yet you get the same benefits of security and governance. In this scenario, you create a so-called proxy cache project that will store your last used images automatically. They can be later pulled from the proxy cache without touching the Docker Hub limit.

Workaround (Worked for me)

5. Copy public images into an Amazon ECR private registry

Create an Amazon Elastic Container Registry (Amazon ECR) repository, and then push the image into this new repository. With this approach, you might avoid exceeding the Docker Hub pull limit by pulling the images from the Amazon ECR repository.

Then, I replaced following line in Dockerfile

FROM python:3.7

with

ARG REPO=655606377847.dkr.ecr.us-west-2.amazonaws.com

FROM ${REPO}/python:3.7

P.S. I tagged python image with 3.7 instead of latest(default)
