Contemplate

Contemplate is a template rendering tool designed to render configuration templates. While it takes inspiration from configuration management systems such as ansible's template action, it is specifically not designed to be a full configuration management system. Furthermore, it's designed to be run on the target system, and ships as a single static binary.

Features

• Template language based on jinja2
• Layered data sources: File, Environment Variables, Kubernetes ConfigMaps and Secrets
• Live re-rendering of templates when data changes
• Notification of configuration changes for downstream daemons
• Builds as a static binary for use in distroless or scratch containers

Usage in Containers

To add Contemplate to a container build, add the following build step to your Dockerfile:

COPY --from=ghcr.io/infrarun/contemplate:latest /contemplate /contemplate
