#helmfile (2023-02)

Moving towards helmfile v1.0 the --args parameter is going to be removed: https://github.com/helmfile/helmfile/blob/main/docs/proposals/towards-1.0.md Does that mean it’ll be removed from all commands (and for my use case specifically the helmfile template command)? In one of our pipelines we do the following to render one specific template in our Helm chart:

CONFIG_FILES=$(helmfile -l name=heweb template --skip-deps --args '--show-only templates/config-files.yaml')

Then later it extracts files from the expanded template and performs some tests against them (such as linting). There doesn’t seem to be an equivalent --show-only flag for the helmfile template command.

Any source from where I can learn and understand, how to write a good helm charts!?

Hi guys, I am trying to install kubeflow “pipeline” component distributed as Kustomization, like it mentioned in “Advanced features” of helmfile. But as mentioned in kubeflow prerequisites , kustomize 4.5.7 renders manifests in different order than 3.2.0, so I got an error that CRDs should be installed first (I compared outputs of helmfile template and kustomize build - there are really difference in ordering of resources) Is there any way to pass kustomize build --reorder legacy flag in helmfile, when I install kustomizations in helmfile.yaml? Maybe there are any other option to control order or kustomized resources? I am using helmfile v0.149.0 Thanks

So I think I am breaking helmfile in an unexpected way? Trying to release 20-25 charts and getting a timeout error E0225 0050.984329 541 round_tripper.go:63] CancelRequest not implemented by *cli.retryingRoundTripper E0225 0050.984398 541 memcache.go:238] couldn’t get current server API group list: Get “https://rancher-cluster/k8s/clusters/foo-bar/api?timeout=32s”: net/http: request canceled (Client.Timeout exceeded while awaiting headers) Error: UPGRADE FAILED: could not get apiVersions from Kubernetes: could not get apiVersions from Kubernetes: Get “https://rancher-cluster/k8s/clusters/foo-bar/api?timeout=32s”: net/http: request canceled (Client.Timeout exceeded while awaiting headers)

yeah if i reduce the number of releases in the top level helmfile the job succeeds. interesting.

it seems to be caused by latency. i am running helmfile in north america against a k8s cluster in europe.

I am having trouble getting the exec function to work. I am trying to set the value from a yaml file into a values.yaml.gotmpl.

the yaml file:

image:
  registry: some.registry.com
  repository: some-repo
  tag: "0.1.1"
  pullPolicy: "Always"
  pullSecrets:
    - "my-secret"

my current gotmpl attempt:

image: |
  {{ exec  "cat some-file.yaml | yq '.image'" }}

The goal is for the resulting gotmpl will be identical to the yaml file.

It fails with the error

error unmarshaling JSON: while decoding JSON: json: cannot unmarshal string into Go value of type map[string]interface {}

Which likely isn’t a helpful error, as I believe that is coming from helmfile templating the chart after the exec command succeeded. But I can’t get helmfile to show me the yaml it generated.

hmm, seems like kustomize 4 detection isn’t working with the nix package for kustomize. Probably because they are passing some flagst to set the git-commit somehow
