I had following terminal output "zsh: command not found: aws" after the installation of the AWS CLI on macOS, because AWS CLI uses python and you need to ensure you did configure python right. That make it a little-bit more tricky for me to install that CLI on my machine, compared for example to the IBM Cloud CLI.
Bash scripting to ensure Kubernetes resources are deleted in synchronization
Sometimes we need to ensure that resources in Kubernetes are fully deleted before we setup other resources. In Kubernetes the timing and the synchronization can be very import and relevant.
