k3s/registry/readme.md

Create a docker registry using helm under the namespace "registry" It should use Longhorn for data storage (which is already set up on cluster) Ingress should be : Traefik ( already set up) Cert-Manager is already set up and should be used. The docker registry should answer to https (443) externally to host: "registry.asterisk.is" docker users should need to login using user:docker pass:dockerpass

Tagging an existing image for private registry upload

docker login docker tag nginx:alpine registry.asterisk.is/nginx:alpine docker push registry.asterisk.is/nginx:alpine

How to use images in Kubernetes

First we need to add secret:

kubectl create secret docker-registry regcred \ --docker-server=registry.asterisk.is \ --docker-username=myuser \ --docker-password=mypassword \ -n registry

Reference it through the pod

spec: imagePullSecrets:

- name: regcred

containers:

- name: myapp
  image: registry.example.com/nginx:alpine
