Helm chart doesn't install the agent anymore? about helm-charts

[ahmed-mez]

Hey @jeremyd thanks for opening the issue and sorry for the trouble!

Could you please make sure you use the latest chart version?

helm repo add datadog https://helm.datadoghq.com
helm repo update

Just to confirm, you shared in the description the content of datadog-values.yaml but in the helm install command you pass datadog_new_values.yaml as argument, could you share the content of datadog_new_values.yaml ?

It could also be interesting to run helm template datadog-agent datadog/datadog -f <your values file> and see whether the Daemonset manifest is present.

If these steps couldn't help you identify and fix the issue, please don't hesitate to contact or solutions team.

Thanks!

Hi @ahmed-mez

Yes I'm using the latest helm chart v2.6.7 from the helm.datadoghq.com repo.

The values are the same, I'm using datadog-values.yaml after confirming that using the stock values.yaml with the modifications from the stripped down version has the same result.

When I run 'helm template datadog-agent datadog/datadog -f ' it shows a DaemonSet. However, when I run helm install --debug, it does not show a DaemonSet. When I run helm upgrade or install it shows 10 resources:

history.go:53: [debug] getting history for release datadog-agent
upgrade.go:121: [debug] preparing upgrade for datadog-agent

Ok, I just tested with an older helm version and it works. So this must be a bug in either helm or the chart with newer helm.

helm version (silently does not create daemonset)
version.BuildInfo{Version:"v3.4.2", GitCommit:"23dd3af5e19a02d4f4baa5b2f242645a1a3af629", GitTreeState:"clean", GoVersion:"go1.14.13"}

helm version (works)
version.BuildInfo{Version:"v3.3.4", GitCommit:"a61ce5633af99708171414353ed49547cf05013d", GitTreeState:"clean", GoVersion:"go1.14.9"}

EDIT: this had nothing to do with version but when I run it in a docker container (with a fresh helm environment) it works. Something must be wrong in my local machine helm settings although I'm not sure what it could be, I deleted any extra repos and refreshed. Now looking for any types of local helm config that may be causing a problem... (is there a dependency cache somewhere or anything from a previous helm install of this chart?)

Thanks @jeremyd for the additional information

is there a dependency cache somewhere or anything from a previous helm install of this chart?

The only dependencies we have are datadog-crds and kube-state-metrics as mentioned here, I don't see how this could affect the DaemonSet installation though.

I wiped all my configs and uninstalled all my plugins (like the secrets plugin). Then I re-added the repos and it works again. Not sure why, thanks for the help.
