Additional context

grafana/grafana#27677

[cgill27]

Google has a pull through caching mirror of dockerhub, use it instead of dockerhub when trying to get around dockerhub rate limits (if not paying for dockerhub account): mirror.gcr.io

[onedr0p]

@cgill27 that doesn't seem to work, it only supports "special" dockerhub images. What "special" means is unclear but maybe only :latest tags.

I had this problem for all of my promtail instances and updates
I've created a docker.io/registry container that act as a proxy registry for all my docker hub images, it works great !

Hi! This issue has been automatically marked as stale because it has not had any
activity in the past 30 days.

We use a stalebot among other tools to help manage the state of issues in this project.
A stalebot can be very useful in closing issues in a number of cases; the most common
is closing issues or PRs where the original reporter has not responded.

Stalebots are also emotionless and cruel and can close issues which are still very relevant.

If this issue is important to you, please add a comment to keep it open. More importantly, please add a thumbs-up to the original issue entry.

We regularly sort for closed issues which have a stale label sorted by thumbs up.

We may also:

• Mark issues as revivable if we think it's a valid issue but isn't something we are likely
  to prioritize in the future (the issue will still remain closed).
• Add a keepalive label to silence the stalebot if the issue is very common/popular/important.

We are doing our best to respond, organize, and prioritize all issues but it can be a challenging task,
our sincere apologies if you find yourself at the mercy of the stalebot.

Still interested in this becoming a reality, thanks!

Not stale

[MatteoJoliveau]

Definitely an issue for us as well, especially when running on AWS spot instances (which get frequently rotated, causing re-pulling). GitHub has a free container registry that is available automatically on all public repositories, it should be easy to integrate in your CI workflow.

[onedr0p]

Given the recent dockerhub announcement of removing free team orgs, I'm wondering if the current grafana org will be affected? And if so perhaps this could finally have a high priority?

[remram44]

It looks like the grafana account is a "verified publisher", which should make it exempt from rate limits.

Removal of rate limiting for developers

Do the rate limits not apply for downloads of the images, or does the wording imply that developers of the verified publisher's org are not subject to rate limits?

[remram44]

Anyone can download from verified publishers without limit.

For some reason that doesn't apply to "official images", only images from "verified publishers". It's weird but seems reliable for now.

Any news on this?

Even if, the Loki helm chart uses 3rd-party software too.
