Asked by Tom Brouwer
Hi,
I did setup FluxCD.io in Kubernetes. It is to automate deployments. It reads the tags from a registry to look if there are new images, if there are, it will deploy them. I use the dockerconfig json to get the images. Flux tells me it using the same credentials to get the list of tags. But it get a unauthenticated error. I try to get the list of tags myself from the same link Flux uses, but I dont know how to authenticate.
How can I authenticate on this url: https://registry.digitalocean.com/v2/registry.digitalocean.com/{reponame}/{imagename}/tags/list
Thanks in advance!

Hi I can not test it right now, I did setup it with Terraform, but cause a lot of work this week I disabled it. But I think I found the problem. It tries to get de tags list of: https://registry.digitalocean.com/v2/registry.digitalocean.com/{reponame}/{imagename}/tags/list
It got a 401. If I try to get the list manually with the same ImagePullSecrets it is also unauthenticated. But when I use the url:
https://registry.digitalocean.com/v2/{reponame}/{imagename}/tags/list
I can authenticate, I do not know the reason exactly anymore why I was using the registry URL in the Flux manifest before the repo name. So this weekend I will apply the cluster with Terraform and try it without the registry as prefix.
Also good to know (I didnt know) the ‘WWW-Authenticate’ header will give more info about auth errors.
