I'm trying to follow either of the following instructions:
https://istio.io/docs/setup/kubernetes/helm-install/
https://github.com/istio/istio/tree/master/install/kubernetes/helm/istio
~ helm repo add istio.io https://storage.googleapis.com/istio-prerelease/daily-build/master-latest-daily/charts
~ helm repo list
NAME URL
stable https://kubernetes-charts.storage.googleapis.com
local http://127.0.0.1:8879/charts
istio.io https://storage.googleapis.com/istio-prerelease/daily-build/master-latest-daily/charts
~ helm repo update
~ helm install install/kubernetes/helm/istio --name istio --namespace istio-system
Error: failed to download "install/kubernetes/helm/istio" (hint: running `helm repo update` may help)
~ helm dependency update install/kubernetes/helm/istio
Error: could not find <current directory>/install/kubernetes/helm/istio: stat
<current directory>/install/kubernetes/helm/istio: no such file or directory
To answer my own question for anyone else with the same issue:
Don't use the public helm repo.
Download a release archive from:
https://github.com/istio/istio/releases
Unpack it, navigate into the istio root directory, then you can successfully do:
Helm 2.x syntax:
helm install install/kubernetes/helm/istio --name istio --namespace istio-system
Helm 3.x syntax:
helm install istio install/kubernetes/helm/istio --namespace istio-system

I'm unable to install the nginx ingress controller on AKS.Since I'm using userDefinedRouting as outboundType for egress when running
helm install nginx-ingress nginx-stable/nginx-ingress -n ingress --set controller.service.annotations."service\.beta\.kubernetes\.io/azure-load-balancer-internal"='"true"' --set controller.service.annotations."service\.beta\.kubernetes\.io/azure-load-balancer-internal-subnet"=x-x-x-aks-ingress-sub01 --set controller.service.loadBalancerIP="10.240.137.40" i can see that it failed to download the image because the root CA is not on the worker node and hence is unable to verify the SSL certificate. This is actually good and I've uploaded the nginx image to my ACR:
docker pull nginx docker tag nginx/nginx-ingress:2.2.2 nameofacr.azurecr.io/hub/nginx/nginx-ingress:2.2.2 and docker push nameofacr.azurecr.io/hub/nginx/nginx-ingress:2.2.2. If it look in the values.yaml file I see this:
values.yaml I've followed how to - helm install using private registry and think that I've added the tag as required but I can't figure out how to run the command now so that it will pull the image from my ACR.
What I've tried:
helm install nginx-ingress nameofacr.azurecr.io/hub/nginx/nginx-ingress -n ingress --set controller.service.annotations."service\.beta\ .kubernetes\.io/azure-load-balancer-internal"='"true"' --set controller.service.annotations."service\.beta\.kubernetes\.io/azure-load-balancer-internal-subnet"=x-x-x-x-aks-ingress-sub01 --set contro ller.service.loadBalancerIP="10.240.137.40"
failed with Error: INSTALLATION FAILED: failed to download "nameofacr.azurecr.io/hub/nginx/nginx-ingress"
or
helm install nginx-ingress --set Image=nameofacr.azurecr.io nginx/nginx-ingress -n ingress --set controller.service.annotations."servi ce\.beta\.kubernetes\.io/azure-load-balancer-internal"='"true"' --set controller.service.annotations."service\.beta\.kubernetes\.io/azure-load-balancer-internal-subnet"=x-x-x-x-aks-ingress-sub01 --s et controller.service.loadBalancerIP="10.240.137.40" resulted in Error: INSTALLATION FAILED: failed to download "nginx/nginx-ingress"
I can't get this to work. Any help please?
Use this chart : ingress-nginx/ingress-nginx. You have an official documentation that explain how to import images to private ACR.
You can use this commands to import images :
az acr import --name nameofacr --source k8s.gcr.io/ingress-nginx/controller:v1.2.1 --force
az acr import --name nameofacr --source k8s.gcr.io/ingress-nginx/kube-webhook-certgen:v1.1.1 --force
Also try to fix the helm chart version helm install nginx-ingress ingress-nginx/ingress-nginx --version 4.1.3, to be sure you use the images related to a specific values.yaml.
This chart is deprecated
Error: INSTALLATION FAILED: failed to install CRD crds/crd-alertmanager.yaml: unable to recognize "": no matches for kind "CustomResourceDefinition" in version "apiextensions.k8s.io/v1beta1"
helm install prometheus monitor/prometheus-operator --namespace prometheus
The chart prometheus-operator is deprecated!
Deprecation message:
DEPRECATED
This chart will be renamed, but first must be deprecated before the prometheus-community/helm-charts repo is indexed, so that it won't be listed in the hubs. See [this prometheus-community issue](https://github.com/prometheus-community/community/issues/28#issuecomment-670406329) for reasoning and next steps.
Try the latest one:
$ helm repo add prometheus-community https://prometheus-community.github.io/helm-charts
$ helm repo update
$ helm install kube-prometheus-stack prometheus-community/kube-prometheus-stack --namespace prometheus
N.B.: The apiVersion for custom resource definitions (CRD) is apiextensions.k8s.io/v1 now.
I have downloaded the latest stable release of istio i.e.1.11.4 and am executing the below command inside the root of the istio release folder:
helm install istio install/kubernetes/helm/istio --namespace istio-system --set grafana.enabled=True --set kiali.enabled=True
When I do, I get the error:
Error: INSTALLATION FAILED: failed to download "install/kubernetes/helm/istio"
My helm version: version.BuildInfo{Version:"v3.7.1"
How can I resolve this error?
You are using some old command to install Istio.
Check out the latest installation docs: https://istio.io/latest/docs/setup/install/helm/#installation-steps
Additionally, the addons (grafana, kiali, or prometheus) are not part of Istio anymore and need to be installed separately as shown here:
Prometheus:
https://istio.io/latest/docs/ops/integrations/prometheus/
Grafana: https://istio.io/latest/docs/ops/integrations/grafana/
Kiali: https://istio.io/latest/docs/ops/integrations/kiali/
Following the install instructions I can not install "ingress-merge".
I first tried :
helm install --namespace kube-system --name ingress-merge ./helm
That gave me the error - "Error: unknown flag: --name"
I searched that issue up and found out that the --name flag is no longer needed.
I next tried the following:
helm install ingress-merge --namespace kube-system ./helm
That gave me the error - Error: path "./helm" not found
I then took out the ./helm:
helm install ingress-merge --namespace kube-system
That gave me the error - Error: must either provide a name or specify --generate-name
What is the correct command structure?
Here is the link with the install instructions:
https://github.com/jakubkulhan/ingress-merge
First clone the git repo
git clone https://github.com/jakubkulhan/ingress-merge.git
Then use below command with helm 3. Notice --name is not needed with helm 3
helm install --namespace kube-system ingress-merge ingress-merge/helm
or below command with helm 2
helm install --namespace kube-system --name ingress-merge ingress-merge/helm
I am trying to install Grafana via helm and have added both the bitnami and stable repo.
from bitnami
helm install bitnami/grafana grafana --set persistence.enabled=true --set persistence.accessModes={ReadWriteOnce} --set persistence.size=8Gi --namespace monitoring
stable
grafana $ helm install stable/grafana grafana --set persistence.enabled=true --set persistence.accessModes={ReadWriteOnce} --set persistence.size=8Gi --namespace monitoring
However, I get the following error:
helm install stable/grafana grafana --set persistence.enabled=true
--set persistence.accessModes={ReadWriteOnce} --set persistence.size=8Gi --namespace monitoring Error: failed to download
"grafana" (hint: running helm repo update may help)
I have tried helm repo update but it doesn't help.
I will appreciate some guidance on this.
Syntax is helm install [NAME] [CHART] [flags]
helm install grafana stable/grafana xxxxx should work
You just put the chart name in the wrong position
Need to search grafana in hub using Helm
helm search hub grafana
helm repo add grafana https://grafana.github.io/helm-charts
helm repo update
helm install my-release grafana/grafana
And for particular namespace:
helm install my-release grafana/grafana -n test-namespace
You can below command:
helm install my-grafana-board grafana/grafana
