Lyrics

[Verse 1]
Start with templates directory, that's where magic lives
Values dot yaml holds the keys, configuration it gives
Chart dot yaml is metadata, defines what you deploy
Helpers dot tpl functions there, for logic you employ

[Chorus]
Helm Charts Template, Values interpolate
Double curly braces, variables translate
Package and release, versions orchestrate
Kubernetes made simple, applications we create

[Verse 2]
Values files cascade down, defaults at the base
Override with dash dash set, environment-specific space
Dot notation paths the way, to nested config trees
Required function validates, ensures no missing keys

[Chorus]
Helm Charts Template, Values interpolate
Double curly braces, variables translate
Package and release, versions orchestrate
Kubernetes made simple, applications we create

[Bridge]
Range loops through arrays clean
If statements guard the scene
Include brings templates in
Named templates share and win
With blocks scope the flow
Pipe functions data flow

[Verse 3]
Dependencies in Chart yaml, sub-charts you define
Hooks run at lifecycle points, pre-install by design
Release object gives you context, namespace name and more
Capabilities tell you features, what your cluster has in store

[Chorus]
Helm Charts Template, Values interpolate
Double curly braces, variables translate
Package and release, versions orchestrate
Kubernetes made simple, applications we create

[Outro]
Template render test it first
Dry run shows what's parsed
Helm the package manager
For Kubernetes deployment star
