Rate limit issue from Docker Hub in "catpipeline" Demo

In this lesson of the demo: https://github.com/acantril/learn-cantrill-io-labs/blob/master/aws-codepipeline-catpipeline/02_LABINSTRUCTIONS/STAGE2-CODEBUILD.md

The docker build fails due to a rate limit on Docker Hub on the Centos base image.

Step 1/7 : FROM centos:7

Fixed by changing the following in the Dockerfile:

FROM centos:7

To

FROM public.ecr.aws/docker/library/centos:7

There already seems to be a pull request open for this but I will leave this here for others.

@ArtistYay it was a while ago now, but I’ll try 😃

So, the error message I included when I raised this issue is (I think) due to DockerHub’s rate limit issue (it used to be free and now it’s not). Centos is also no longer in development/support I believe, so this combined with DockerHub’s rate limit/fees was the cause.

AWS built a public ECR gallery (equivalent to DockHub when it was free) so I used that instead.

Hope this helps.

Yes sir helped a lot! Thank you!
