Installing helm Redash on Minikube return Error(redash-scheduler container redis connection error)

Question

I tried to set up Redash on a local environment using Minikube and Helm, but encountered an Two errors.

• The Minikube cluster is configured with 4 CPUs and 8GB of memory.
• The Helm Redash URL used is https://github.com/getredash/contrib-helm-chart.
• Two errors occurred during this process.
  • OSError: [Errno 99] cannot assign requested address
  • redis.exceptions.ConnectionError

---

During the process of creating the Redash environment, an access denied error occurred when executing mkdir command in redis and postgresql Pod, so I solved the problem by creating local-path storgae instead of using standard storage.

---

After that, when we create Redash with Helm, problems occur in two pods, as shown in the second screenshot.

• Some pods that create redash-server containers and redash-scheduler containers have problems. Especially, an error similar to the first screenshot continues to occur in Redash-scheduler.

To reproduce, you can simply enter the following command.

• labtop & OS version : m1 mac Monterey 12.1
• minikube version : v1.30.1
• kubectl version : 1.27.1
• helm version : v3.8.2
• helm redash version : 3.0.0(latest)

# minikube start
$ minikube start --nodes 3 --driver=docker

# default addson turn-off
$ minikube addons disable storage-provisioner

# setting local-path-storge by rancher and change default storage
$ kubectl apply -f https://raw.githubusercontent.com/rancher/local-path-provisioner/v0.0.20/deploy/local-path-storage.yaml
$ kubectl patch storageclass local-path  -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
