CockroachDB doesnt start and init doesnt seem to launch

[DelaunayAntoine]

Hello everyone,

I would like to deploy cockroachDB using helm but the problem is that the cluster can't start and I get this error that keeps appearing: Error I240718 13:09:06.023104 191 server/init.go:405 ⋮ [T1,Vsystem,n?] 37 ‹cockroachdb-1.cockroachdb.cockroachdb.svc.cluster.local:26257› is itself waiting for init, will retry

Can you help me by giving me some hints on how to fix the problem?

Here's the entire log file and the values.yaml file db.txt values-cockroach.txt

I'm using cockroach version 24.1.1 The chart 13.0.1

What do you expect to see ?

The cockroach cluster launching just fine

What happened

Error I240718 13:09:06.023104 191 server/init.go:405 ⋮ [T1,Vsystem,n?] 37 ‹cockroachdb-1.cockroachdb.cockroachdb.svc.cluster.local:26257› is itself waiting for init, will retry

I'm seeing this as well. Did you figure it out?

I see this in the log, it looks like its trying the wrong url to the pods:

W240826 16:03:30.251454 142 server/init.go:407 ⋮ [T1,Vsystem,n?] 37  outgoing join rpc to ‹keycloak-cockroachdb-1.keycloak-cockroachdb.keycloak.svc.cluster.local:26257› unsuccessful: ‹rpc error: code = Unavailable desc = connection error: desc = "transport: error while dialing: dial tcp: lookup keycloak-cockroachdb-1.keycloak-cockroachdb.keycloak.svc.cluster.local: no such host"›
I240826 16:03:30.258373 142 server/init.go:405 ⋮ [T1,Vsystem,n?] 38  ‹keycloak-cockroachdb-2.keycloak-cockroachdb.keycloak.svc.cluster.local:26257› is itself waiting for init, will retr

In my case its adding in 'keycloak-cockroachdb.' and in your case its adding in 'cockroachdb.', which it looks like it shouldn't be.

I've got the same problem with the latest 14.0.3 chart. I suppose that the reason is in helm hooks annotations of init job template. https://github.com/cockroachdb/helm-charts/blob/master/cockroachdb/templates/job.init.yaml#L22 Post-install hook can't be triggered because the stateful set is not ready. As a workaround you may deploy the init job manifest from the template manually.

Are either of you able to share your values file? A redacted version is likely fine, just to see what overrides you have set. I have. not ben able to reproduce this with the default values.

@udnay , here ya go:

$ cat Chart.yaml 
apiVersion: v2
name: jellyfin
description: A Helm chart for Kubernetes

# A chart can be either an 'application' or a 'library' chart.
#
# Application charts are a collection of templates that can be packaged into versioned archives
# to be deployed.
#
# Library charts provide useful utilities or functions for the chart developer. They're included as
# a dependency of application charts to inject those utilities and functions into the rendering
# pipeline. Library charts do not define any templates and therefore cannot be deployed.
type: application

# This is the chart version. This version number should be incremented each time you make changes
# to the chart and its templates, including the app version.
# Versions are expected to follow Semantic Versioning (https://semver.org/)
version: 0.1.0

# This is the version number of the application being deployed. This version number should be
# incremented each time you make changes to the application. Versions are not expected to
# follow Semantic Versioning. They should reflect the version the application is using.
