Conform
+ DRY, hygienic, fast builds.
+
+ 
+ 
+
+
+ 
+ 
+ 
+
+
+ 
+ 
+
+
+
+---
+
+**Conform** is a tool for building projects in a flexible and reliabale manner.
+
+The key features of Conform are:
+- **DRY**: Templatized multi-stage Docker builds.
+- **Hygienic**: Builds run in Docker.
+- **Fast**: Leverages Docker caching, building only what has changed.
+
+Getting Started
+---------------
+Create a file named `conform.yaml` with the following contents:
+```yaml
+metadata:
+ repository: example
+scripts:
+ init : |
+ #!/bin/bash
+
+ set -e
+
+ echo "Hello, world!"
+templates:
+ build: |
+ FROM alpine:latest as build
+ RUN echo "Run your build here!"
+ RUN touch artifact
+ test: |
+ FROM alpine:latest as test
+ COPY --from=build artifact .
+ RUN echo "Run your tests here!"
+ image: |
+ FROM scratch as image
+ RUN echo "Deply your image here!"
+ COPY --from=build artifact .
+rules:
+ all:
+ templates:
+ - build
+ - test
+ - image
+
+```
+
+In the same directory, run:
+```
+$ conform enforce all
+```
+> **Note:** Conform is still under design. The YAML layout is subject to change.
