I have a helm chart that requires stable/redis as a child chart. The parent chart needs to expose the redis service as an environment variable. The redis chart includes a template called redis.fullname . How can I refer to this in my parent chart? I.e. I want something like this in my parent deployment but it doesn't work: kind: Deployment spec: template: containers: env: - name: REDIS_CLUSTER_SERVICE_HOST value: {{ template "redis.fullname" . }} You can use '{{ .Release.Name }}-redis' in your parent chart. I had same requirement. This is my example in case you want to take a look -> https:/

I’m trying to change the value of a variable if another variable it set by combining the two with a dash in the middle, I’m not sure of the syntax to do this, I’m thinking of somethings like: {{- $serviceNamespace := .Values.serviceNamespace -}} {{- $serviceTag := .Values.serviceTag -}} {{- if $serviceTag}} {{- $serviceNamespace := .Values.serviceNamespace "-" .Values.serviceTag -}} {{- end}} Is this correct? if serviceNamespace was hello and serviceTag was 1.0.0 would I end up with serviceNamespace being hello-1.0.0 ? For concatenation just use printf: {{- $serviceNamespace := printf "%s-%s"

I've by mistake installed an unsecured configuration of tiller. I've tried helm reset but something must have corrupted because now when I try to install helm: $HELM_HOME has been configured at /home/chris/.helm. Warning: Tiller is already installed in the cluster. (Use --client-only to suppress this message, or --upgrade to upgrade Tiller to the current version.) Happy Helming! However if I try helm ls I get: Error: could not find tiller . So because helm reset is insufficient, or there is some bugs, which resources do I need to delete in order to be able to reinstall helm correctly ( helm

I want to use the postgresql chart as a requirements for my Helm chart. My requirements.yaml file hence looks like this: dependencies: - name: "postgresql" version: "3.10.0" repository: "@stable" In the postgreSQL Helm chart I now want to set the username with the property postgresqlUsername (see https://github.com/helm/charts/tree/master/stable/postgresql for all properties). Where do I have to specify this property in my project so that it gets propagated to the postgreSQL dependency? This topic is very clearly described here: https://helm.sh/docs/developing_charts/#using-the-child-parent
