问题 How can I pass the entire JSON string to a Helm chart value? I have values.yml where the config value should contain entire JSON with a configuration of an application ... config: some JSON here ... and I need to pass this value to a secret template and then mount it as a volume to a Kubernetes pod. {{- $env := default "integration" .Values.env}} apiVersion: v1 kind: Secret metadata: name: {{ .Release.Name }}-{{ $env }} type: Opaque data: config.json: {{ .Values.config | b64enc | quote }}

问题 Using helm for deploying chart on my Kubernetes cluster, since one day, I can't deploy a new one or upgrading one existed. Indeed, each time I am using helm I have an error message telling me that it is not possible to install or upgrade ressources. If I run helm install --name foo . -f values.yaml --namespace foo-namespace I have this output: Error: release foo failed: the server could not find the requested resource If I run helm upgrade --install foo . -f values.yaml --namespace foo

问题 We have a production AKS cluster that has a stable/cert-manager helm chart installed to allow using Let's Encrypt certificates. The current version installed is cert-manager-v0.6.0 in the kube-system namespace. Let's Encrypt is to stop support for traffic from cert-manager pre 8.0 version from 1st of November 2019. I would like to upgrade but the latest available stable chart version is v0.6.7 . Seems like the way to go is to switch to jetstack/cert-manager . How do I best approach this?

问题 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" . }} 回答1: You can use '{{ .Release.Name }}-redis'

I tried listing the repos helm repo list but it is empty. I tried to add the stable repo: helm repo add stable https://github.com/helm/charts/tree/master

问题 Helm charts define helper templates in _helpers.tpl which are used to create normalized names for the services. The standard form of the template for a service (DNS) name is: {{- define "postgresql.fullname" -}} {{- $name := default .Chart.Name .Values.nameOverride -}} {{- printf "%s-%s" .Release.Name $name | trunc 63 | trimSuffix "-" -}} {{- end -}} If using postgresql as a subchart, how are you supposed to use DNS-based service discovery to refer to it? A common pattern seems to be to copy

问题 I’m currently using kubernetes and I came across of helm. Let’s say I don’t like the idea of “infecting” my kubernetes cluster with a process that is not related to my applications but I would gladly accept it if it could be beneficial. So I made some researches but I still can’t find anything I can’t easily do by using my yaml descriptor and kubectl so for now I can’t find an use except,maybe, for the environizing. For example (taking it from guides I read: you can easily install application
