Uninstall via Helm chart

Finally, let’s utilize one last command to uninstall objects.

Prerequisites:

• Completion of the previous lessons.

In this lesson, you will:

• Uninstall objects using helm uninstall qotd-system.

If you haven’t already, run the following command:

helm list

You will see your Helm-installed packages listed, such as this:

helm list
NAME            NAMESPACE                       REVISION        UPDATED                                 STATUS          CHART                   APP VERSION
qotd-system     rhn-engineering-dsch-dev        2               2024-08-29 16:21:51.6124129 -0400 EDT   deployed        qotd-system-0.2.0       1.0.0

Now comes the easy part: deleting all that you did. Use one simple command:

helm uninstall qotd-system

You have uninstalled your system by using a Helm command.

Conclusion

We have walked you through an example that shows the power and simplicity of Helm charts. While not always for use in every situation, they have their place in the quiver of OpenShift tools. With this very basic start, you are able to use Helm charts while learning more about their power and ease of use.
