I’ve created helm chart which is working as expected, however I want to change the names of the deployed application currently for each deployment I got different (random) name and I want it to be a fixed name, how can I do that?
This is the helper
{{/* vim: set filetype=mustache: */}}
{{/*
Expand the name of the chart.
*/}}
{{- define "unleash.name" -}}
{{- default .Chart.Name .Values.nameOverride | trunc 63 | trimSuffix "-" -}}
{{- end -}}
{{/*
Create a default fully qualified app name.
We truncate at 63 chars because some K8S name fields are limited to this (by the DNS naming spec).
*/}}
{{- define "unleash.fullname" -}}
{{- $name := default .Chart.Name .Values.nameOverride -}}
{{- printf "%s-%s" .Release.Name $name | trunc 63 | trimSuffix "-" -}}
{{- end -}}
This is the outcome of the name after deployment
crabby-ibex-postgresql-0 0/1 Pending 0 1s
crabby-ibex-unleash-86775cdffd-xt575 0/1 ContainerCreating 0 1s
This is the names from the values yaml
replicaCount: 1
namespace: unleash
restartPolicy: Never
name: a-unleash
nameOverride: unleash
e.g. I want it instead of
crabby-ibex-unleash-86775cdffd-xt575
to be like
unleash-service
uleash-postgressql
update
I've added the following to the _helper.tpl
{{- if .Values.fullnameOverride -}}
{{- .Values.fullnameOverride | trunc 26 | trimSuffix "-" -}}
{{- end -}}
and put the following in the values.yml
fullnameOverride: apps
i expect that the artifacts will start with apps
and it doesnt work
I don't know, why nobody posted it yet. You can pass the name of the Helm release to the helm install
command:
helm install <your_Chart.yaml_directory> -n <release_name>
Based of name crabby-ibex-unleash-86775cdffd-xt575
I guess you are using kind: Deployment
for this application, if you change kind
to StatefulSet
in you yaml you will end up with pod named uleash-postgressql-0
, but because of helm you have additional prefix, you could use --name=you_relese_name
which will create pod you_relese_name-uleash-postgressql-0
.
If you really want to get rid of helm chart prefix you have to set fullnameOverride
for every chart you are deploying.
EDIT: To make use of fullnameOverride
you have to define it in your _helpers.tpl
file.
{{/* vim: set filetype=mustache: */}}
{{/*
Expand the name of the chart.
*/}}
{{- define "unleash.name" -}}
{{- default .Chart.Name .Values.nameOverride | trunc 63 | trimSuffix "-" -}}
{{- end -}}
{{/*
Create a default fully qualified app name.
We truncate at 63 chars because some K8S name fields are limited to this (by the DNS naming spec).
*/}}
{{- define "unleash.fullname" -}}
{{- if .Values.fullnameOverride -}}
{{- .Values.fullnameOverride | trunc 26 | trimSuffix "-" -}}
{{- else -}}
{{- $name := default .Chart.Name .Values.nameOverride -}}
{{- printf "%s-%s" .Release.Name $name | trunc 63 | trimSuffix "-" -}}
{{- end -}}
