Hi! I am new to k3d. I tried to create a cluster, but in my environment i can not reach ghcr.io and docker.io, only over a nexus which proxy to this repos. I tried to set my nexus repo in registries.yaml, but nothing changed when i create a cluster with --registry-config. Its always try to connect to ghcr.io and docker.io. Can somebody help me on this? Thanks!

So are you behind some kind of corporate proxy? Are there some logs you can provide?

Generally if you're behind a proxy you should use

k3d cluster create --config cluster-config.yaml

# cluster-config.yaml
apiVersion: <http://k3d.io/v1alpha4|k3d.io/v1alpha4>
kind: Simple
metadata:
  name: my-cluster
env:
  - envVar: all_proxy=${all_proxy}
    nodeFilters:
      - server:*
  - envVar: ALL_PROXY=${ALL_PROXY}
    nodeFilters:
      - server:*
  - envVar: http_proxy=${http_proxy}
    nodeFilters:
      - server:*
  - envVar: HTTP_PROXY=${HTTP_PROXY}
    nodeFilters:
      - server:*
  - envVar: https_proxy=${https_proxy}
    nodeFilters:
      - server:*
  - envVar: HTTPS_PROXY=${HTTPS_PROXY}
    nodeFilters:
      - server:*
  - envVar: no_proxy=${no_proxy}
    nodeFilters:
      - server:*
  - envVar: NO_PROXY=${NO_PROXY}
    nodeFilters:
      - server:*

or if you don't want to create a config file

k3d cluster create -e "HTTPS_PROXY=${HTTPS_PROXY}@server:*" -e "HTTP_PROXY=${HTTPS_PROX}@server:*" ...

Thanks for the reply. I need to use the nexus repository for this, so not the proxy. So i want to see in the logs this: Trying to pull repository myownnexus/k3d-io/k3d-tools:5.4.9 instead of this: try to pull repository ghcr.io/k3d-io/k3dtools:5.4.9

for this the config should look a bit like this:

# cluster-config.yaml
apiVersion: <http://k3d.io/v1alpha4|k3d.io/v1alpha4>
kind: Simple
metadata:
  name: my-cluster
registries:
  config: |
    mirrors:
      <http://ghcr.io|ghcr.io>:
        endpoint:
          - <https://myownnexus>

note that I'm assuming

myownnexus

is a domain without a path If you do need to change the path you will need to use "rewrites" which are not supported in

k3d

right now (pending PR)
