A simple library for building Dockerfile pre-processors.
Dockerfile pre-processors aim to make extending Dockerfile with new domain-specific instructions easy. Simply build your own pre-processor and pipe Dockerfiles in on stdin.
Here is a simple hello world usage of the API:
package main
import (
"github.com/garethr/dockerfilepp"
)
func main() {
replacements := map[string]string{
"CUSTOM_INSTALL": "RUN apt-get install thing",
"CUSTOM_ECHO": "RUN echo hello",
}
dockerfilepp.Process(replacements, "include comprehensive help text here")
}
As a example implementation see dockerfilepp-puppet which uses local files compiled into the binary rather than hard coded variables.
