distribworks / dkron-helm Goto Github PK

I noticed that persistence.size exists in values.yaml.
But the helm tempaltes not including a pvc yaml.

If we can create a pvc and locate at /dkron to replace empty volume ?

Hi Team,

I was trying to use the dkron helm chart to install in my local k8s cluster. However I am encountering the following error while trying to add the repo:

helm repo add dkron https://github.com/distribworks/dkron-helm/dkron
Error: looks like "https://github.com/distribworks/dkron-helm/dkron" is not a valid chart repository or cannot be reached: failed to fetch https://github.com/distribworks/dkron-helm/dkron/index.yaml : 404 Not Found

Can someone please help how do I use the dkron-helm to install dkron in my K8s cluster?

Thanks.

I installed a dkron using helm in kubernetes, no configuration has been made, only add toleration in values.
But when I checked the UI, there's no leader, could you help me about this ?

Is there anything that I need to be set to run a Dkron in kubernetes ?

When using the Helm chart, we cannot specify more than 3 server.replicas for server nodes or the cluster will not bootstrap (I've tried multiple times).

The workaround is to install the cluster:

helm install --name dkron ./dkron-helm

When the cluster is formed, bring up additional server nodes one at a time:

kubectl scale deployment dkron-server --replicas=4
# Watch logs to make sure they come online
kubectl scale deployment dkron-server --replicas=5
# Watch again.
