问题
I have installed SCDF in a microk8s cluster. Ubuntu runs in VirtualBox.
Now I'm trying to register a custom app in SCDF.
My app is build as a Docker image (myorg/myapp:latest) and registered in a private local registry (localhost:5000).
I followed the microk8s documentation here https://microk8s.io/docs/registry-private
and add my Docker registry in the containerd-template.toml file :
[plugins.cri.registry.mirrors."myorg"]
endpoint = ["http://localhost:5000"]
But now I can't figure out how to register my app in SCDF.
When I try to register my app with "docker:myorg/myapp:latest" and then deploy it, I have an error in microk8s :
Failed to pull image "myorg/myapp:latest": rpc error: code = Unknown desc = failed to resolve image "docker.io/myorg/myapp:latest": no available registry endpoint: pull access denied, repository does not exist or may require authorization: server message: insufficient_scope: authorization failed
It's like microk8s is not looking in my Docker local registry.
Thanks for any help

There's support to resolve Docker images from the private Docker registry. You'd either have to configure the setting as a global property in SCDF or it can be supplied as part of the individual stream deployment.
See: SCDF + Private Docker Regisrty
Nothing changes in your registration command, however. With the imagePullSecret passed correctly, the image should then resolve after a successful negotiation.
