This broke our builds since we rely on several public Docker images, and by default, Docker uses docker.io.

Thankfully, AWS provides a docker.io mirror for those who can't wait:

  FROM public.ecr.aws/docker/library/{image_name}

In the error logs, the issue was mostly related to the authentication endpoint:

▪ https://auth.docker.io → "No server is available to handle this request"

After switching to the AWS mirror, everything built successfully without any issues.

Mild irony that Docker is down because of the AWS outage, but the AWS mirror repos are still running...

Also, docker.io is rate-limited, so if your organization experiences enough growth you will start seeing build failures on a regular basis.

Also, quay.io - another image hoster, from red hat - has been read-only all day today.

If you're going to have docker/container image dependencies it's best to establish a solid hosting solution instead of riding whatever bus shows up

Rate limits are primarily applied to unauthenticated users, open source projects and business accounts have none/much higher tresholds

based on the solution, it seems like it is quite straightforward to switchover

I wasn't able to get this working, but I was able to use Google's mirror[0] just fine.

Just had to change

    FROM {image_name}

to

    FROM mirror.gcr.io/{image_name} 

Hope this helps!

We tried this initially

  FROM mirror.gcr.io/{image_name}

We received

  failed to resolve source metadata for mirror.gcr.io/

So it looks like these services may not be true mirrors, and just functioning as a library proxy with a cache.

If you're image is not cached on one of these then you may be SOL.

public.ecr.aws was failing for me earlier with 5XX errors due to the AWS outage: https://news.ycombinator.com/item?id=45640754

I manage a large build system and pulling from ECR has been flaking all day
