We’re thinking how we can use helmfile to add a new object definition to a third-party chart we have no control over. I know that it should be possible, but can’t find any examples. Appreciate any help)
Oblivious option is to use raw chart to deploy raw manifests + helmfile dependencies. But it may not suit your needs. I have some ugly example of strategicMergePatches to patch resulting yaml on the fly:
- name: test0
namespace: test0
createNamespace: true
chart: dysnix/nginx
wait: false
waitForJobs: false
atomic: false
values:
- values/test0.yaml.gotmpl
strategicMergePatches:
- apiVersion: apps/v1
kind: Deployment
metadata:
name: test0-nginx
spec:
template:
spec:
initContainers:
- name: sleep
image: alpine:latest
imagePullPolicy: "IfNotPresent"
command:
- /bin/sh
- -c
- sleep 7200
Yes, I definitely have a raw chart solution in my mind, but thought that maybe there would be a more elegant solution to treat the whole thing as a bundle.
In your example it seems this dysnix/nginx has a Deployment object, right, and you just mutate it? We tried with strategicMergePatches: with a new object and helmfile threw an error: failed to find unique target for patch
yes, strategicMergePatches works w/ existing object only
Yeah, that’s what I thought. It seems the less cryptic way would be, as you mentioned, a new release with an additional object even though I would like to avoid it. Thanx!

Hi All, How can I add an already deployed helm chart to be managed by helmfile? Thank you!
Hi, you may try to write a helmfile release using values from deployed helm chart helm get values <release-name>

Hello everyone, I’m just starting with helmfile and was wandering whether it can sufficiently cover the following use-case: I have multiple micro-services with separated charts - I use single umbrella-chart to install them at once. Everything works fine until I want to install separate chart into an environment where umbrella had already been installed… I came up with a few hacks but this is wrong and against best practices (according to this issue https://github.com/helm/helm/issues/9433) Is it possible to manage charts like that with helmfile without aforementioned issue? I.e. install charts both separately and through helmfile?
Yep, perfectly possible with helmfile.
@steenhoven so I can install my chart (for service A) into the namespace and then install a bundle of charts (service A, B, C etc.) into same namespace through helmfile without problems?
no. But you can create different ‘stacks’ for different environments.

hello again) I think I miss something about Environment values files https://helmfile.readthedocs.io/en/latest/#environment
as per this example I’m able to use separate values from values.yaml in environments section (in the values.yaml.gotmpl)
But is there a way to simply merge the whole values file from environments section?
my helmfile looks like this right now
environments:
default:
values:
- git::<https://gitlab-ci-token>:{{ env "CI_JOB_TOKEN" }}@gitlab
releases:
- name: my_app
namespace: staging
chart: repo/chart
version: 0.5.0
values:
- "values.yaml"
- "values.yaml.gotmpl"
ok, found out that it’s rather easy to control this via go-templating
Does helmfile support helm’s native hooks?
"helm.sh/hook": pre-install,pre-upgrade,post-install,post-upgrade
Helmfile has it’s own hooks https://helmfile.readthedocs.io/en/latest/#hooks
We are using a vendor’s chart which has [helm.sh/hook](http://helm.sh/hook) specified. Do you know if helmfile will execute those?
I’ve found that Kustomize, Spinnaker, Argo, Flux, … will not.
helmfile is just a wrapper for helm, thus the hook should be executed by helm, if not disabled explicitly
