NOTES:
1. Get the application URL by running these commands:
  export POD_NAME=$(kubectl get pods --namespace default -l "app=verdaccio,release=vested-lobster" -o jsonpath="{.items[0].metadata.name}")
  kubectl port-forward $POD_NAME 8080:4873
  echo "Visit http://127.0.0.1:8080 to use your application"

alt verdaccio

Then, follow the notes.

We export the application

export POD_NAME=$(kubectl get pods --namespace default -l "app=verdaccio,release=veering-gorilla" -o jsonpath="{.items[0].metadata.name}")

and we expose the port

➜ kubectl port-forward $POD_NAME 8080:4873
Forwarding from 127.0.0.1:8080 -> 4873
Forwarding from [::1]:8080 -> 4873

Verdaccio is up and running.

http://127.0.0.1:8080/#/

Publishing a Package

Let's log in.

➜ npm adduser --registry  http://127.0.0.1:8080
Username: user
Password: ***
Email: (this IS public) user@domain.com
Logged in as user on http://127.0.0.1:8080/.

and now we can publish

➜ npm publish --registry http://127.0.0.1:8080
+ @kubernetes/hellonode-example@1.0.0

Scale

Check the pod name (if you do not include --name) on install helm, kubernetes generate a random name.

➜ kubectl get pods
NAME                                         READY     STATUS    RESTARTS   AGE
veering-gorilla-verdaccio-666d9488bc-n9p27   1/1       Running   0          11m

Let's scale

➜ kubectl scale deployment veering-gorilla-verdaccio --replicas=3
deployment.extensions "veering-gorilla-verdaccio" scaled

Problems

I had this issue trying to install verdaccio helm, to solve it I just run a command and all works perfectly.

Registered user can't login

If you are facing this issue please read the following link https://github.com/verdaccio/verdaccio/issues/943#issuecomment-427670085

Connection refused

➜ helm install stable/verdaccio
Error: Get http://localhost:8080/api/v1/namespaces/kube-system/configmaps?labelSelector=OWNER%!D(MISSING)TILLER: dial tcp 127.0.0.1:8080: connect: connection refused

Run the following script to solve it.

kubectl -n kube-system patch deployment tiller-deploy -p '{"spec": {"template": {"spec": {"automountServiceAccountToken": true}}}}'

Tiller pod is missing

➜ helm install stable/verdaccio
Error: could not find a ready tiller pod

Run this to fix it.

helm init --upgrade
