Reinstall the Helm chart for Python Setup

563

In this article, we will learn how we can simply relaunch our Python setup. In the previous post, when we released the resources while uninstalling the helm chart we kept the PVC storage. To use the same existing storage, we can simply use the same helm chart name and we can connect to the existing PVC.

Steps to follow: 

Check Kubernetes context

We have to use icekube context otherwise we will install the helm chart accidentally on the local environment.

Command to switch from existing context to icekube context with ltu-default namespace

kubectl config set-context icekube --namespace=ltu-default
                   OR
kubectl config use-context icekube 
kubectl config set-context --current --namespace=ltu-default

 

Command to switch from existing context to another remote context with namespace

Command to list the current context used.

kubectl config current-context

Reinstall Helm Chart

Once you are sure that you have switched to icekube context you can proceed to install helm chart. You need to open bash shell and switch to the .helm directory of the extracted project folder.

The complete path of the .helm folder is PYTHON_SETUP_KUBERNETES->repository->.helm

Switch to .helm directory
Switch to .helm directory

Note

To use the existing PVC storage use the same name for the helm chart, you have used sumit36124091

Use the below command along with the unique name and give file path to values_icekube.yaml which is located under the current directory.

helm install --debug sumit36124091  ./ -f ./values_icekube.yaml

You will get a message in the end that Python is installed.

So, finally, you have reinstalled the helm chart with the same name so that you can use your existing PVC storage. In the next post we will discuss how to free the PVC resource as well after you uninstall the helm chart.
