Interpolation

Introduction

Oftentimes, you will need to define variables whose values depend on other variables.
To do this, you can use Value interpolation.

Starting with some examples always works best in these cases.

Some Examples

• An environment variable identifier containing a complete identifier for your Bunnyshell environment.
  {{ project.name }} : {{ org.name }} : {{ env.name }}

• A variable that is using the identifier variable to create a logging content prefix.
  {{ "now"|date("m/d/Y") }} {{ env.var.identifier|lower }}

• A variable that interpolates a conditional value
  {% if env.type == 'ephemeral' %}true{% else %}false{% endif %}

Where to use value interpolation

• Variables (at Project, Environment, or Component level)
• Docker-compose Components or DockerImage Components
  • Build arguments
  • Build context
  • Build Dockerfile
  • Build target
• Helm Charts
  • Values
• Terraform
  • Input variables
  • Configuration variables
  • Environment variables
• Static applications build command

Available interpolation values

• Organization variables
  • org.name
  • org.unique
• Project variables
  • project.name
• Environment variables
  • env.unique
  • env.name
  • env.type - primary / ephemeral
  • env.k8s.namespace
  • env.vars.NAME
• Components variables
  • components.COMPONENT_NAME.gitBranch
  • components.COMPONENT_NAME.ingress.hosts[*]
  • components.COMPONENT_NAME.vars.NAME
