Conditionally enable apps

[EmandM]

Currently the enable flag just takes a straight boolean as to whether the chart is enabled or not. It would be nice to have a conditional option, based on a runtime argument the app will be conditionally enabled or disabled.

There is something that will do such job just fine: env vars in DSF

An example:

---
apps:
  my-app:
    enabled: $MY_APP_ENABLED
    secretsFiles:
      - "../values/[...].yaml"

MY_APP_ENABLED=(true|false) helmsman -spec [...]

It's up to you wether it's true or false in the end, so that is the place where you can use your conditions. Sounds enough?

It would be preferable to have something similar to Helm's feature to conditionally enable sub-charts. Linking to a variable in the values.yaml or something similar. Specifically I'm looking for something that would allow us to enable different charts based on environment.

Helm's solution looks like this

apiVersion: v2
name: myapplication
description: A Helm chart for Kubernetes
type: application

dependencies:
  - name: apidocs
    condition: apidocs.enabled

So I'd be looking for something like this

apps:
  my-app:
    enabled: myapp.enabled
    valuesFiles:
      - "../values/[...].yaml"

[EmandM]

Though I am aware that the structure of helmsman might make this unfeasible

As Mateusz mentioned, you can use env variables for this. Another alternative, you can use YAML anchors, something like this:

apps:
  my-app:
    enabled: &myappEnabled true
    secretsFiles:
      - "../values/[...].yaml"
  otherapp:
    enabled: *myappEnabled
    secretsFiles:
      - "../values/[...].yaml"

with way whenever you disable my-app the otherapp will also be disabled.
