Platform Templates

Output templates for generating configuration files in different formats.

Template Subdirectories

Configs (configs/)

Configuration file format templates:

• toml.j2 - TOML format output
• yaml.j2 - YAML format output
• json.j2 - JSON format output

These templates convert Nickel configuration objects to format-specific files.

Kubernetes (kubernetes/)

Kubernetes manifest templates:

• deployment.yaml.j2 - Deployment manifests
• configmap.yaml.j2 - ConfigMap for configuration
• service.yaml.j2 - Service definitions
• ingress.yaml.j2 - Ingress routing

Docker Compose (docker-compose/)

Docker Compose templates:

• docker-compose.yaml.j2 - Complete docker-compose.yml

Template Usage

Templates use Jinja2 syntax for variable substitution:

# Example: toml.j2
[backend]
host = "{{ backend.host }}"
port = {{ backend.port }}
workers = {{ backend.workers }}

[database]
url = "{{ database.url }}"
pool_size = {{ database.pool_size }}

Generate output:

# Render TOML template with Nickel data
nickel export vapora.solo.ncl | \
  jinja2 templates/configs/toml.j2 > vapora.solo.toml
