Environment Values

This example loads a small YAML document into memory and uses it in a service environment variable.

log_level: info

loads:
  - name: app_values
    statics:
      - content:
          name: app_values
          content: |
            test:
              message: hello world

print: 'config file: {{ env "CONFIG_FILE" }}'

services:
  - name: show-env
    path: .
    command: env
    inherit_env: true
    env:
      TEST: "1"
      TEST_MESSAGE: "{{ .app_values.test.message }}"
      HOSTTYPE: '{{ env "HOSTTYPE" }}'
    filters:
      - SECRET

inherit_env copies the current process environment first, then env overrides or adds values.

Even with inherit_env: false (the default), a minimal baseline such as PATH, HOME, TMPDIR, USER, LANG is always inherited from the parent process so commands keep working; set them explicitly in env to override.
