Additional installation notes

Soon, we will explore the WordPress application that we just installed. First, there are several areas of consideration that should be mentioned before leaving behind the topic of installation.

The -n flag

The -n flag can be used instead of the --namespace flag to reduce the typing effort when entering commands.

Let's look at how we can set this environment variable on various operating systems:

• You can set the variable on macOS and Linux as follows:

  $ export HELM_NAMESPACE=chapter3

• Windows users can set this environment variable by running this command in PowerShell:

  > $env:HELM_NAMESPACE...
