Hi...Actually I have made a docker file that runs helmfile apply i want to get the status of 'helmfile apply'.So that my job can fail if helmfile fails.

Can anyone help me debug why

values:
  - runnerRegistrationToken: ""
    installed: true

releases:
  - name: {{ .Environment.Name }}
    namespace: "gitlab"
    labels:
      chart: "gitlab-runner"
      repo: "gitlab"
      namespace: "gitlab"
      vendor: "gitlab"
    chart: "gitlab/gitlab-runner"
    version: "v0.9.0"
    wait: true
    installed: {{ .Values.installed }}
    tillerNamespace: "gitlab"
    values:
      - imagePullPolicy: Always
        gitlabUrl: <http://git.url.com|git.url.com>
        runnerRegistrationToken: {{ .Values.runnerRegistrationToken }}
        runners:
          tags: {{ .Environment.Name }},eks
          serviceAccountName: "admin"
        rbac:
          create: true

bases:
  - defaults.yaml

Results in

releases/gitlab-runner.yaml: error during gitlab-runner.yaml.part.0 parsing: template: stringTemplate:16:25: executing "stringTemplate" at <.Values.installed>: map has no entry for key "installed"

Calling it from my root helmfile like so:


  # Deployment Stack
  - path: releases/gitlab-runner.yaml
    values:
    - installed: {{ .Environment.Values | get "namespaces.installed" true }}
      runnerRegistrationToken: {{ .Environment.Values.gitlab.runnerRegistrationToken }}

I see this happen every now and then and can never figure out what I did to have it render properly

sung kangover 6 years ago(edited)

I believe the states do get merged properly from the debug logs


first-pass produced: &{utility map[installed:false runnerRegistrationToken:foo] map[]}

first-pass rendering result of "gitlab-runner.yaml.part.0": {utility map[installed:false runnerRegistrationToken:foo] map[]}

second-pass rendering failed, input of "gitlab-runner.yaml.part.0":

Hmm very odd, may be a bug. Unless I pass down a nested state value helmfile doesn’t seem to want to render.

Is it possible to have helmfile rollback a deployment if the pods return ErrImagePull?

Nelson Jeppesenover 6 years ago

Have atomic, force and wait set to true but it does not seem to do that

here you see it killing the old working pod with a new pod in ErrImagePull status but reporting a success and not rolling back

Nelson Jeppesenover 6 years ago

I think I've got it figured out, in a way. If I use a replica greater than 1, it works as I'd hope

Hi. I recently started using Helmfile and now try to have 2 environments (clusters) deployed using Jenkins parallel pipeline steps. But one of them results in error because of missing env vars. It works fine if I disable the 'other parallel step'. So... I think under the hood Helmfile does some in place intermediate rendering that doesn't play nice when 2 processes are operating on the same underlying workspace.

Does this look familiar or does anyone have tips on how to debug or where to dig for more information? (Short-term fix will be: No parallelisation)

Hi, anyone able to get --args working? I like helmfile diff --args='--context=2' but it fails when using helmfiles feature. I see this in debug log:

Building dependency release=foo, chart=../foo

exec: helm dependency build ../foo --context=2

Basically, how do I inform it to only use --context=2 when doing helm diff?

Steve Nolenover 6 years ago

potentially a simple (albeit weird) question: Is there a way to inject the value passed to helmfile via --kube-context into a variable of a release?

Steve Nolenover 6 years ago

or potentially less abstractly, I'd like to know if there is a way to inject the name of the current cluster I'm operating on into a variable

hey guys, helmfile newbie here, i’m looking to keep my all charts values in 1 file that defines an environment
ppe.yaml

namespace: ppe-test

nginx:
  replicas: 2
  tag: 1.0.79
  chart: stable/nginx

traefik:
  replicas: 2
  tag: 1.0.79
  chart: stable/traefik

templates.yaml

templates:
  default: &default
    namespace: "{{ .Values.namespace }}"
    missingFileHandler: Error
    chart: "{{ `{{ .Release.Name }}`.chart }}"
    values:
      - envs/{{ .Environment.Name }}.yaml

helmfile.yaml

bases:
  - envs/environments.yaml
---
{{ readFile "templates.yaml" }}

releases:
- name: nginx
  <<: *default

is it possible to access the .Release.Name and to pass it to env values?

Is rollback possible in helmfile...similar to rollback in helm

staretsover 6 years ago

is there some “escape sequence” for variable values containing valid templating expressions, like:


abc: "{{  template "slack.general.text" . }}"

(in my case this value shouldn’t be rendered, but passed as-is)
