Specifying relative paths to the values within the parameters?

[narun4sk]

Given the following:

parameters:
  elasticsearch:
    image: "quay.io/pires/docker-elasticsearch-kubernetes:5.5.0"
    java_opts: "-Xms512m -Xmx512m"
    replicas: 1
    masters: 1
    roles:
      master:
        image: ${elasticsearch:image}

Instead of specifying ${elasticsearch:image} I would like to be able to use a relative path, something similar to ${...:image}.

Hence:

• ${.:key_name} - looks up key_name in the local context (here all keys within master)
• ${..:key_name} - looks up key_name in the context one level up (here all keys within roles)
• etc...
