argocd version.Describe the bug
The installation fails due to rate limits on Docker Hub:
~
Failed to pull image "argoproj/argocd@sha256:b835999eb5cf75d01a2678cd971095926d9c2566c9ffe746d04b83a6a0a2849f": rpc error: code = Unknown desc = Error reading manifest sha256:b835999eb5cf75d01a2678cd971095926d9c2566c9ffe746d04b83a6a0a2849f in docker.io/argoproj/argocd: toomanyrequests: You have reached your pull rate limit. You may increase the limit by authenticating and upgrading: https://www.docker.com/increase-rate-limit
~
To Reproduce
Pull images.
Expected behavior
It would be great to provide an alternate location of the container images, which doesn't have such tight rate limits.
Screenshots
See above
Version
Paste the output from `argocd version` here.

Agree, this is bad. We are currently evaluating a target registry for migration of the images.

FYI, I just submitted an application to have argoproj exempted from the limit.

@edlee2121 shall we start moving all our images to google container registry and changing default instal manifests to use it?
Another option is github container registry, although it's a bit unproven.
@jessesuen That's not a bad option. Your call. If you decide to move it, please ensure you setup appropriate access controls.
GitHub container repository (https://ghcr.io) works quite well, as does https://quay.io
