Network Policy usage is inverted.

It's easier to list the services that you want to connect to, but Network Policy forces you to list all clients that can connect to your pod.

How would you even know that another team plans to connect your apps?

But if Network Policy is not the right tool, then what should you use?

In this KubeFM podcast, you will explore:

- How Network Policies are not as bad as you might think, but they are low-level APIs that are not always practical to use directly.
- Intent-based Access Control (IBAC) as a higher-level abstraction to describe your network segmentation requirements.
- How you can use IBAC to generate Network Policies, Istio Authorization Policies, AWS IAM & Roles, and more.

Helm is a popular tool for templating and packaging Kubernetes resources, but does it mean it's the best?

In this episode of KubeFM, Jacco draws a parallel between Helm and PHP and the similarity in which both tools became a success despite their focus on templating strings.

You will also learn:

- Helm's flaws and how you can avoid them.
- Alternative tools that can (partially) replace Helm.
- How to manage third-party packages and templating internal YAML resources.

Jacco shared several examples demonstrating duplication in Helm charts and a lack of structured typing.
