Is it expected that helmfile ignores kubeContext if it doesn’t exist? I just noticed that behaviour, haven’t doublechecked it though.

mumoshualmost 7 years ago

not expected. helmfile just passes it to helm commands so I’d expect helm should fail if the kubeContext you’ve provided and then passed by helmfile doesn’t exist!

Andrew Nazarovalmost 7 years ago

I’m using helm tiller plugin, btw. Well, I’ll check it out again and create an issue.

Andrew Nazarovalmost 7 years ago

Can variables taken from environments like {{ .Environment.Values.imageTag }} be rendered from helmfile.yaml? For some reason it always shows me <no value>. Am I missing something? From the docs it should work, but…

Andrew Nazarovalmost 7 years ago

However {{ .Environment.Name }} is rendered correctly.

Andrew Nazarovalmost 7 years ago

It seems it doesn’t work when I have bases: defined. Probably I’ve read about that in some thread or issue….

mumoshualmost 7 years ago

The “remote helmfiles” feature is coming! I’d appreciate it if you could test it out: https://github.com/roboll/helmfile/pull/648

mumoshualmost 7 years ago

especially @Erik Osterman (Cloud Posse) 😃

Andrew Nazarovalmost 7 years ago

Does helmfile has some sort of global timeout somewhere?

I’ve got “ERROR: Job failed: execution took longer than 1h0m0s seconds”. As for helm operations the timeout is set to 1200 sec via helmDefaults. The execution of tillerless approach is much longer especially when we have failing releases.

Erik Forsbergalmost 7 years ago

Hi! The example helmfile refers to a helm-git plugin. I can only find a helm-git plugin that takes github/gitlab URLs, not git+https - so a link to this plugin would be appreciated.

Erik Forsbergalmost 7 years ago

Another question: The docs says I need to disable concurrency if I run with tillerless. Is there a way to do this from configuration file, (i.e. the helmfile.yaml), or only from commandline?

Andrew Nazarovalmost 7 years ago

A bit more about concurrency. It would be great to have --concurrency flag defined in docs and in help output of helmfile.

SeBalmost 7 years ago

Hi guys,
I have a template issue, I’d like to have in a release the “chart: ” value to be computed according to the version set in environment so that when :
• the version has some value like “0.1.3" the chart definition is chart: myregistry/mychart
• the version is empty or not set the chart def is a local chart chart: ../mychart
I thought that the following would work

environments:
  dev:
    values:
      - tpsvc-configVersion: ""
  prod:
    values:
      - tpsvc-configVersion: 1.0


templates:
  chart: &chart
    {{- $versionKey := printf "%sVersion" `{{.Release.Name}}` }}
    chart: {{ .Environment.Values | get ($versionKey) "" | eq "" | ternary "../.." "talend" }}/{{`{{.Release.Name}}`}}
    version: {{.Environment.Values | get ($versionKey) ""}}

releases:
- name: tpsvc-config
  <<: *chart

But it does not

SeBalmost 7 years ago

Do you have any idea to solve this, if it is even possible.

Andrew Nazarovalmost 7 years ago

During the aforementioned conversation I thought about the following.
I was wondering if something like this is possible with helmfile (forgive me for the syntax I don’t know how to show embedded part):
{{ .Environment.Values.{{ .Release.Name }}.version }}?

Is there any chance to have that sort of templating? Or it just makes no sense?

SeBalmost 7 years ago(edited)

I don’t understand why when I do this the rendering fails

releases:
- name: tpsvc-config
  chart: {{ `{{ .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" | eq "" | ternary "../.." "talend" }}` }}/{{`{{.Release.Name}}`}}

SeBalmost 7 years ago

with an error err: failed to read helmfile.config.yaml: reading document at index 1: yaml: line 15: did not find expected key

SeBalmost 7 years ago(edited)

but when I do this

releases:
- name: tpsvc-config
  chart: ../{{`{{.Release.Name}}`}}

This renders properly‹

Andrew Nazarovalmost 7 years ago

What if you try without get? The same pipeline but with .Environment.Values.tpsvc-configVersion? Sorry for interfering again, I just find your approach useful for one of my use cases.

SeBalmost 7 years ago

I’ll try but this should not be any different.

SeBalmost 7 years ago

and also this will fail cause value resolution does not support a dash in the values 😞

mumoshualmost 7 years ago

Not sure what’s causing your confusion exactly, but try:


releases:
- name: tpsvc-config
  chart: |
    {{`{{ .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" | eq "" | ternary "../.." "talend" }}` }}/{{`{{.Release.Name}}`}}

SeBalmost 7 years ago

Hi @mumoshu thanks a lot ! this is working but I have another issue though. The version of a release seem not to accept templatization

releases:
- name: tpsvc-config
  chart: |
    {{ `{{  .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" | eq "" | ternary "../.." "talend" }}` }}/{{`{{.Release.Name}}`}}
  version: |
    {{` {{ .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" }}` }}

SeBalmost 7 years ago

it is failing with :

  Error: chart "tpsvc-config" matching {{ .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" }} not found in talend index. (try 'helm repo update'). improper constraint: {{ .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" }}

mumoshualmost 7 years ago

Ah, that sounds like not implemented!

mumoshualmost 7 years ago

// hold on..

SeBalmost 7 years ago

yep

SeBalmost 7 years ago

it seems that the version is missing here 🙂

mumoshualmost 7 years ago

You found it!

SeBalmost 7 years ago

Do you want me to create an issue ?

mumoshualmost 7 years ago

Please do so! It’s even nicer if you directly create a PR to add it 🙂

SeBalmost 7 years ago

yep I know 🙂

SeBalmost 7 years ago

I’ll try to find some time tonight

SeBalmost 7 years ago

thank anyway for the “|” tip, yaml is always a mystery for me.

Andrew Nazarovalmost 7 years ago

Wow, it’s great to know about “I”.

SeBalmost 7 years ago

@mumoshu can you explain why the | is required for this scalar, why the initial string does not work. is it because the the ” inside the string ?

SeBalmost 7 years ago

I have made it work using the simple quote to surround the string like

  chart: '{{ `{{  .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" | eq "" | ternary "../.." "talend" }}`'

SeBalmost 7 years ago

it fails using the double quote even with the inside double quote escaped ?

mumoshualmost 7 years ago

@SeB That’s basically due to that {{ whatever }}//{{ whatever }} isn’t a valid yaml string

mumoshualmost 7 years ago


chart: {{` {{  .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" | eq "" | ternary "../.." "talend" }} ``}

evaluates to


chart: {{  .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" | eq "" | ternary "../.." "talend" }}

which looks chart: {{ whatever }}//{{ whatever }} for the yaml parser

mumoshualmost 7 years ago


chart: '{{ `{{  .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" | eq "" | ternary "../.." "talend" }}`}}'

this works cuz it evaluates to:


chart: '{{  .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" | eq "" | ternary "../.." "talend" }}'

which looks chart: 'str' to the yaml parser

SeBalmost 7 years ago

ok thanks a lot for the explanation

mumoshualmost 7 years ago


chart: "{{` {{  .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" | eq "" | ternary "../.." "talend" }} `}}"

and this is close but doesn’t work in your case as you have " in release tempaltes

mumoshualmost 7 years ago(edited)

it evaluates to


chart: "{{  .Environment.Values | get (printf "%sVersion" "tpsvc-config") "" | eq "" | ternary "../.." "talend" }}"

and it looks chart: "{{ .Enviro...ersion" "tpsvc-config") "" | eq "" ..... to the yaml parser

) and | eq should look like stray terms to the yaml parser

and probably chart: "{{ .Enviro...ersion" "tpsvc-config" is chart: "str1" "str2" which isn’t valid as well

SeBalmost 7 years ago

ha ok.

mumoshualmost 7 years ago

my understanding may be incomplete but that’s probably it 🙂

: | should always work

Andrew Nazarovalmost 7 years ago

Probably it would be useful to mention this trick somewhere in the docs. It’s not that obvious at first.

Justice Londonover 6 years ago

Howdy. Not sure if this question has been asked before... but how do you get selectors when specifying an environment to work? I get an error if I use something like:


helmfiles:
   - path: environments/coreserv/production/helmfile.yaml

---
releases:
  - name: mycoolrelease
    labels:
       team: coreserv

---
`helmfile -e production -l team=coreserv diff`

Justice Londonover 6 years ago

If I don't use an environment it is able to find the helmfile releases defined there.

mumoshuover 6 years ago

@Justice London Just replied in the thread

SeBover 6 years ago(edited)

Hello @mumoshu
Is it on purpose that there is no documentation on the new state value introduced here :
https://github.com/roboll/helmfile/pull/647

Cedric Meuryover 6 years ago

Yo fellow Helmfile freaks 😆

mumoshuover 6 years ago

Hey! 👋

timduhenchanterover 6 years ago(edited)

Is it possible to get helmfile template to only spit out YAML within the executable? Right now I’m just nuking all the lines before the first --- match but I’m not familiar enough with helmfile yet to know that this will resolve all cases of non-templated output

mumoshuover 6 years ago

Yeah! I thought I've changed all the logs to go stderr and made stdout dedicated to actual template output.
But that's not the case, right? If you could comment on the relevant github issue about redundant lines you saw, it would help me fixing it

Ryan Richardsover 6 years ago

Really like the content you guys publish. Also am enjoying helmfile.

Ryan Richardsover 6 years ago

Im using terraform to build the cluster and would like to use helmfile for configuring all the post-installation tasks.

Erik Osterman (Cloud Posse)over 6 years ago

if only we had a terraform-helmfile-provider 😃

Alexisover 6 years ago

hey guys, just want to know if it's possible to use reuse-values in helmfile?

Erik Osterman (Cloud Posse)over 6 years ago

helmfile supports YAML anchors

Erik Osterman (Cloud Posse)over 6 years ago

might that help?

Erik Osterman (Cloud Posse)over 6 years ago

we also use environment variables to do this

mumoshuover 6 years ago

And helmfile has never intended to support helm’s --reuset-values because it defeats the one of purposes of helmfile - reproducible deployments!
But I may be missing something - what’s your goal for --reuset-values @Alexis?

mumoshuover 6 years ago

We now have a Kubernetes operator for helmfile

https://github.com/roboll/helmfile/issues/153
https://github.com/mumoshu/helmfile-operator

I’m trying to build something that complements weaveworks/flux, argo-cd, brigadecore/brigade…

Erik Osterman (Cloud Posse)over 6 years ago

Amazing!

Erik Osterman (Cloud Posse)over 6 years ago

excited to take a look

mumoshuover 6 years ago

Ask me anything! I’m not yet sure how to best describe it myself

mumoshuover 6 years ago

one of limitations of flux, argo-cd is that it’s inability to run helmfile apply on git commit.. it works by sourcing k8s manfiests generated by helmfile template(both of em allows you to run helmfile template automatically on git commit btw)

mumoshuover 6 years ago

normally it makes many useful helm commands unusable. helm test, helm status, helm list, and so on.

mumoshuover 6 years ago(edited)

with helmfile-operator you can manage Helmfile custom resources in git, so that argo-cd or flux can reconcile helmfile crs on git commit, and then the operator runs helmfile commands

mumoshuover 6 years ago

brigade is basically a ci/cd system that takes JavaScript code as a pipeline definition. so just run helmfile apply from js that is triggered via git commit

mumoshuover 6 years ago

or create Helmfile custom resources from the pipeline and the rest is the same as argo-cd and flux.

Andrew Nazarovover 6 years ago

Man, I’ve been waiting for something like helmfile operator. Even thought about trying to write it by myself, but 🍾🍾 - it’s here. I’ll definitely take a look.

Andrew Nazarovover 6 years ago

Really great news!

Erik Osterman (Cloud Posse)over 6 years ago

how are errors handled? e.g. a bad helmfile rollout?

Erik Osterman (Cloud Posse)over 6 years ago(edited)

i imagine helmfile diff is not really suitable for this workflow?

Andrew Nazarovover 6 years ago

What I find tricky in Argo and Flux is how they handle multi-cluster setup. I think it should be easier to do with helmfile-operator.

mumoshuover 6 years ago

// Just recalled that I was in the process of renaming the project from appliance-operator to helmfile-operator.. Hold on

Erik Osterman (Cloud Posse)over 6 years ago

aha, that is more clear to me

Erik Forsbergover 6 years ago

Is there any variable I can use from within a hook to anchor my paths to the directory of the helmfile?

The use case is that I'm modifying a namespace via an kubectl apply -f <file>, and right now I must be in the same directory as the helmfile, i.e I can't use --file to point at the helmfile, or the <file> won't be found. So if there is a variable, and hook arguments are templated, then.. I could.

Sean Turnerover 6 years ago(edited)

Does helmfile ever get locked out? I've been trying to install a couple of deploys, a service, ingress, service-account, cluster-role-binding, and configmap, and I started getting the following error (after many helmfile applys). However, I switched clusters, and stopped getting the error...

jqjqover 6 years ago

Is there a way to run a custom script everytime a helmfile command is run? One usecase is that when I run a helmfile -e ENV … I want to run a script to check my KUBECONFIG is pointing to the right cluster for the environment. I can do it as a release hook, but the release hook declaration has to be duplicated for every release. It’d be nice if I can define a hook globally.

hi @mumoshu can I add repositories.yaml file to bases? it contains repositories spec

yeah it should work

mumoshuover 6 years ago

could you try moving base dir out of helmfile.d?

Ribhararnus Pracutiarover 6 years ago

yes, I have tried that too

mumoshuover 6 years ago

hmm, could you add --log-level=debug like helmfile --log-level=debug to hopefully see at which point helmfile is failing?

actually my original helmfile is complicated and debugging for hours, I don't know what's happening, until I am surprised that the repositories base part causes the error a while ago

Ribhararnus Pracutiarover 6 years ago

anyway, Thank you very much for your support @mumoshu

mumoshuover 6 years ago(edited)

@Ribhararnus Pracutiar according to the logs your issue isn’t resolved yet, right? I’ll take a look and try to see what can go wrong tonight 🙂 thanks for reporting!

Ribhararnus Pracutiarover 6 years ago(edited)

No worries buddy. Right still not resolved, maybe I wanna use repositories in every file, violate DRY till the issue resolved 😁

Hmm.. Does a non-default environment inherit values from the default environment? I.e, values not defined under "production", will they inherit value defined under "default"?

@mumoshu just to let you know I had a good time contributing to the helmfile project but I will certainly not contribute anymore. We have decided to leverage the ansible scripts we are using for production deployment also for the developer workflow. I believe it is too big a machinery compared to helmfile but this is a pragmatical decision for now to not multiply our tools.

This project is awesome and will keep an eye on it.

How do I make helmfile stop if there's trouble with one of the charts? I.e, I don't want it to continue setting up chart B if chart A had any kind of trouble. Is that the wait parameter? I'm already running with concurrency 1 since I use tillerless.

I'm confused to to best use readFile with .gotmpl when pulling in a non-yaml file

I have this in a values .gotmpl file, and it works

extraConfigMaps:
  output.conf: |-
    <match **>
      @id elasticsearch
      @type elasticsearch
...

I'd like to use this, so I can pull out that large xml into it's own file fluentd-elasticsearch.xml

extraConfigMaps:
    output.conf: |-
    {{ readFile "fluentd-elasticsearch.xml" | indent 2 }}

but I keep getting error converting YAML to JSON: yaml: line 35: could not find expected ':'

mumoshuover 6 years ago

Hey! Try this:


extraConfigMaps:
    output.conf: |-
{{ readFile "fluentd-elasticsearch.xml" | indent 6 }}

mumoshuover 6 years ago(edited)

not sure why you have 4 spaces before output.conf but you can also try:


extraConfigMaps:
  output.conf: |-
{{ readFile "fluentd-elasticsearch.xml" | indent 4 }}

mumoshuover 6 years ago(edited)


extraConfigMaps:
    output.conf: |-
    {{ readFile "fluentd-elasticsearch.xml" | indent 2 }}

this won’t work cuz we get


extraConfigMaps:
  output.conf: |-
    <match **>
  @id elasticsearch
  @type elasticsearch
...

Can I update the requirment version of a helm chart that I am using ?
So in this case I am using stable/prometheus-operator and would like to update the grafana version to 3.5 instead of 3.3

Ribhararnus Pracutiarover 6 years ago

hi @mumoshu is yesterday issue not resolved yet?

Ribhararnus Pracutiarover 6 years ago

anyway, I want to ask question here regarding multi-line string

Ribhararnus Pracutiarover 6 years ago

local.yaml:


config: |
  test: a
  yes: true

in helmfile chart, template/configmap.yaml


default.yaml: |
  {{ tpl .Values.config . }}

Ribhararnus Pracutiarover 6 years ago

but after deployment, or sync, I only have


default.yaml:
  test: a

not including yes: true

Ribhararnus Pracutiarover 6 years ago

is it true?

mumoshuover 6 years ago

@Ribhararnus Pracutiar Regarding the issue you had yesterday, yeah, I think I got it.

Try adding the below to repositories.yaml:


environments:
  local: {}
  development: {}
  staging: {}
  production: {}

Ribhararnus Pracutiarover 6 years ago

ok thanks, maybe later I comeback with the issue, as for now, I use repositories in every single helmfile

Ribhararnus Pracutiarover 6 years ago

what about above issue?

Ribhararnus Pracutiarover 6 years ago

ah Im sorry, you replied on my message, wait

Nelson Jeppesenover 6 years ago(edited)

What's the appropriate way to run a post deploy task?

I'm spinning up an elasticsearch cluster, but after i do I want helm to run a few curl commands. I'm thinking about creating a chart with a cronjob,but is there a better way?

I know about post hooks, but that runs locally where the helmfile is run, right? Id rather run this once in a pod on the k8s cluster.

Can I access the name of the current release in some variable, inside a values template file?

Erik Forsbergover 6 years ago

I.e, I have two nginx-ingress releases, ingress-test and ingress-production, and I want to set antiaffinity based on the release name, from a values template.

Ryan Richardsover 6 years ago

What is the recommended approach for converting a standard helm chart into a helmfile? if there is documentation on this i apologize.

Erik Osterman (Cloud Posse)over 6 years ago

@Ryan Richards is there a helm chart in particular? we might have an example of it.

Erik Osterman (Cloud Posse)over 6 years ago(edited)

See https://github.com/cloudposse/helmfiles/tree/master/releases

Andrew Nazarovover 6 years ago

I wouldn’t call it a conversion, wrapping maybe 😉 But it doesn’t really matter. Yes, cloudposse has a lot of great examples. Thank you for this, btw!

Ryan Richardsover 6 years ago

If you wanted to run a simple script that, lets say creates a few namespaces, could you do this somewhere with helmfiles? I found that working with terraform null resource didn't work as i expected. If there is a best-practice for running these kind of configuration processes i would love to hear about it 🙂

Erik Osterman (Cloud Posse)over 6 years ago

Helm will by default create the namespace for you. No need to do anything fancy.

Ryan Richardsover 6 years ago

@Erik Osterman (Cloud Posse) thanks, i was using that as an example. We have several post-setup configuration steps that need to occur once our terraform is finished with the basic cluster setup in gke. These include things like setting default limits.

Ryan Richardsover 6 years ago

Most of these tasks are installing prometheus, grafana etc. Im working now to create helmfiles for these but there are a few that to be repeatable would need to be run as scripts or something

Ryan Richardsover 6 years ago

hopefully my statement made sense 🙂 Im simply trying to find the best manner to apply configuration changes that dont involve installing or deploying. Running gcloud commands to obtain connectivity to a specific cluster would be another example.

Erik Osterman (Cloud Posse)over 6 years ago

you can trigger commands as part of hooks
