It is considered good (almost mandatory) practice to set defaults with `default` for any object that originates from `.Values`. (In some places, an `if` conditional guard may be better suited. We'll see those in the next section.)
In an actual chart, all static default values should live in the values.yaml, and should not be repeated using the `default` command (otherwise they would be redundant). However, the `default` command is perfect for computed values, which can not be declared inside values.yaml. For example:
In some places, an `if` conditional guard may be better suited than `default`. We'll see those in the next section.
Template functions and pipelines are a powerful way to transform information and then insert it into your YAML. But sometimes it's necessary to add some template logic that is a little more sophisticated than just inserting a string. In the next section we will look at the control structures provided by the template language.
