Jenkins X Passing value of custom variable into helm Values

Question

Summary I have custom variable in Values.yaml file of helm, i need to assign the value of this variable during build release stage. ... clientname: XYZ ...

Steps to reproduce the behavior I tried to use eskaffold to send the vaule through setEnv

apiVersion: skaffold/v1beta2
kind: Config
build:
  artifacts:
  - image: 'myimagename'
    context: .
    docker: {}
  tagPolicy:
    envTemplate:
      template: '{{.DOCKER_REGISTRY}}/{{.IMAGE_NAME}}/{{.CLIENT_NAME}}:{{.VERSION}}'
  local: {}
deploy:
  kubectl: {}
profiles:
- name: dev
  build:
    tagPolicy:
      envTemplate:
        template: '{{.DOCKER_REGISTRY}}/{{.IMAGE_NAME}}/{{.CLIENT_NAME}}:{{.DIGEST_HEX}}'
    local: {}
  deploy:
    helm:
      releases:
      - name: '{{.CLIENT_NAME}}'
        chartPath: charts/'{{.CLIENT_NAME}}'
        setValueTemplates:
          image.repository: '{{.DOCKER_REGISTRY}}/{{.IMAGE_NAME}}/{{.CLIENT_NAME}}'
          image.tag: '{{.DIGEST_HEX}}'
          clientname: 'myclientname'

Expected behavior the value of client name Values.yaml set to myclientname

Actual behavior the value in Values.yaml not changed

@AlejandroTeixeiraMuñoz [Jenkins X](https://jenkins-x.io) (new generation) has little to nothing to do with [Jenkins](https://jenkins.io). — masseyb, Jan 08 '20 at 16:36

As far as I know skaffold is no longer used by the pipeline. They have switched the builder to google kaniko. The best way to insert values into your template is via charts/myapp/templates/deployment.yaml and charts/myapp/values.yaml.

Try adding the following to values.yaml

env:
   clientname: myclientname

Update deployment.yaml template to substitute value (other vars can be used than env, this was just shown for the purposes of demoing the substitution)

# ...
spec:
      containers:
        env:
        - name: clientname
          value: {{ .Values.env.clientname }}
# ...

I use skaffold with the [kaniko](https://skaffold.dev/docs/pipeline-stages/builders/docker/#dockerfile-in-cluster-with-kaniko) builder, they’re not mutually exclusive. — masseyb, Jan 08 '20 at 09:12
