[BUG] Cannot pull image from local registry while running on Macos

[AyliD]

What did you do

• How was the cluster created?

  • k3d registry create local-registry --port 5050
  • k3d cluster create mycluster --registry-use k3d-local-registry:5050 --config cluster_config.yaml

    
    apiVersion: k3d.io/v1alpha3
    kind: Simple
    name: salut
    servers: 1
    agents: 1
    ports:

  • port: 8000:32080 nodeFilters:
    • server:0:direct
  • port: 8443:32443 nodeFilters:

  • port: 20018:30018 nodeFilters:

    • arg: '--disable=traefik,servicelb' nodeFilters:
      • server:* kubeconfig: updateDefaultKubeconfig: true switchCurrentContext: true

• What did you do afterwards?

  • updated docker engine insecure registries:

    $ cat ~/.docker/daemon.json  | jq -r .
    {
    "experimental": false,
    "debug": true,
    "insecure-registries": [
    "k3d-local-registry:5050",
    "host.k3d.internal:5050",
    "registry.localhost:5050"
    ],
    "registry-mirrors": [
    "https://registry-1.docker.io"
    ]
    }

  • docker push localhost:5050/nginx
  • Was able to curl from some pod the registry via:

    $ kubectl run curl --image=radial/busyboxplus:curl -i --tty --rm
    If you don't see a command prompt, try pressing enter.
    [ root@curl:/ ]$ curl host.k3d.internal:5050/v2/_catalog
    {"repositories":["nginx"]}

Wasnt able to start new pod using image from local registry:

kubectl run mynginx --image=host.k3d.internal:5050/nginx -i --tty --rm

Error:

  Normal   Pulling    13s   kubelet            Pulling image "host.k3d.internal:5050/nginx"
  Warning  Failed     13s   kubelet            Failed to pull image "host.k3d.internal:5050/nginx": rpc error: code = Unknown desc = failed to pull and unpack image "host.k3d.internal:5050/nginx:latest": failed to resolve reference "host.k3d.internal:5050/nginx:latest": failed to do request: Head "https://host.k3d.internal:5050/v2/nginx/manifests/latest": http: server gave HTTP response to HTTPS client

What did you expect to happen

Was hoping image will be pulled properly and pod will be running.

Hi @AyliD , thanks for opening this issue! So you're trying to run the pod with --image=host.k3d.internal:5050/nginx, but you never registered the registry under the name host.k3d.internal... During cluster creation, you configured --registry-use k3d-local-registry:5050 via flag and registry.localhost:5000 via configfile.
