helm install airflow-staging airflow-stable/airflow --version “7.14.0” --namespace staging  --set airflow.config.AIRFLOW__KUBERNETES__GIT_BRANCH=master --set dags.git.ref=“https://github.com/pedaling/class101-airflow.git” --values staging-values.yaml

it gives this error --

Error: failed to download "airflow-stable/airflow" at version "“7.14.0”" (hint: running helm repo update may help)

so I type the helm repo update then it return --

Hang tight while we grab the latest from your chart repositories... ...Successfully got an update from the "airflow-stable" chart repository Update Complete. ⎈Happy Helming!⎈

even I typed helm repo update it always return the same error like

Error: failed to download "airflow-stable/airflow" at version "“7.14.0”" (hint: running helm repo update may help)

what can I do?

To install the stable/airflow follow the steps from the repo README: https://github.com/airflow-helm/charts/tree/main/charts/airflow

I have copied the relevant section below.

1 - Add the Repo:

helm repo add airflow-stable https://airflow-helm.github.io/charts
helm repo update

2 - Install the Chart:

⚠️ find values for CHART_VERSION under GitHub Releases

export RELEASE_NAME=my-airflow-cluster # set a name!
export NAMESPACE=my-airflow-namespace # set a namespace!
export CHART_VERSION=8.X.X # set a version!
export VALUES_FILE=./custom-values.yaml # set your values file path!

# Helm 3
helm install \
  $RELEASE_NAME \
  airflow-stable/airflow \
  --namespace $NAMESPACE \
  --version $CHART_VERSION \
  --values $VALUES_FILE

# Helm 2
helm install \
  airflow-stable/airflow \
  --name $RELEASE_NAME \
  --namespace $NAMESPACE \
  --version $CHART_VERSION \
  --values $VALUES_FILE

3 - Access the WebUI

⚠️ browse to http://localhost:8080 after running the following commands

export NAMESPACE=my-airflow-namespace # set a namespace!

export POD_NAME=$(kubectl get pods --namespace $NAMESPACE -l "component=web,app=airflow" -o jsonpath="{.items[0].metadata.name}")
kubectl port-forward --namespace $NAMESPACE $POD_NAME 8080:8080

I don't know the exact reason why that error is generated (maybe to old version) but I experienced the same by running

helm upgrade airflow -f values.yaml airflow-stable/airflow --version airflow-7.16.0

Solution:
Go to GitHub Releases

1. Find your release, mine for example is 7.16.0 and copy link to its .tgz

https://github.com/airflow-helm/charts/releases/download/airflow-7.16.0/airflow-7.16.0.tgz

2. Execute helm pull to your local directory

helm pull https://github.com/airflow-helm/charts/releases/download/airflow-7.16.0/airflow-7.16.0.tgz

3. And finaly upgrade using local chart

helm upgrade airflow -f values.yaml airflow-7.16.0.tgz
