Push docker image to registry installed using microk8s addon

After you enable registry on the microk8s, run this script

kubectl get svc -n container-registry

you can see that microk8s has redirect registry service's port 32000 to 5000, then I use ingress to expose via https.

First, you have to enable ingress on microk8s:

microk8s.enable ingress

then, you have to create a tls sceret if you want to use https :

openssl genrsa -aes128 -out server.key 2048openssl req -newkey rsa:2048 -nodes -keyout server.key -x509 -days 3650 -out server.crtkubectl create secret tls registry-secret-tls --cert=server.crt --key=server.key -n container-registry

then use kubectl apply -f to create an ingress for revese proxy of registry service.

apiVersion: extensions/v1beta1kind: Ingressmetadata:  name: registry  namespace: container-registry  annotations:    nginx.ingress.kubernetes.io/ingress.class: nginx    nginx.ingress.kubernetes.io/proxy-body-size: "500m"    nginx.ingress.kubernetes.io/proxy-pass-headers: "Location"spec:  tls:  - hosts:    - ingress.local    secretName: registry-secret-tls  rules:  - host: ingress.local    http:      paths:      - path: /        backend:          serviceName: registry          servicePort: 5000

then, add 127.0.0.1 ingress.local to /etc/hosts file. At last, use buildah push docker images to ingress.local.

buildah push --tls-verify=false 44c92e82c220 docker://ingress.local/datacenter-school

This time, it looks everything is ok. But when I try list images in microk8s, I can't find the image that I just pushed.

microk8s.ctr images ls -q |grep datacenter-school

That's quiet weird!
