Tuffenuff 1.0.1

Tuffenuff

Simple F# DSL for generating dockerfiles.

Why?

1. To work with more flexing scripts and ability to reuse Dockerfile code.
2. Becouse I can.

Usage

Hello, World!

#r "nuget: Tuffenuff"

open System.IO
open Tuffenuff

df [
    !/ "Simple Hello World dockerfile"
    from "alpine:3.18"
    cmd [| "echo" ; "'Hello world'" |]
]
|> render
|> toFile (Path.Combine(__SOURCE_DIRECTORY__, "Dockerfile"))

will create Dockerfile with following content:

# Simple Hello World dockerfile
FROM alpine:3.18

CMD [ "echo", "'Hello world'" ]

More complex example

foo.fsx

#r "nuget: Tuffenuff"

open Tuffenuff
open Tuffenuff.DSL

let echoMaessage () =
    df [
        !/ "this is from 'foo.fsx'"
        !> """echo 'echo "Shalom!"' > /etc/profile.d/welcome.sh"""
    ]

Dockerfile.part

# this is from 'Dockerfile.part'
ENTRYPOINT [ "/bin/bash", "-l" ]

bar.fsx

#r "nuget: Tuffenuff"
#load "foo.fsx"

open System.IO
open Tuffenuff
open Tuffenuff.DSL
open foo

let part1 = echoMaessage ()

let part2 =
    Dockerfile.fromFile (Path.Combine (__SOURCE_DIRECTORY__, "Dockerfile.part"))

df [
    !/ "Partial dockerfile"
    from "ubuntu:latest"
    !&part1
    !&part2
]
|> Dockerfile.render
|> Dockerfile.toFile (Path.Combine (__SOURCE_DIRECTORY__, "Dockerfile.Partial"))

will create Dockerfile with following content:

# Partial dockerfile
FROM ubuntu:latest

# this is from 'foo.fsx'
RUN \
    echo 'echo "Shalom!"' > /etc/profile.d/welcome.sh

# this is from 'Dockerfile.part'
ENTRYPOINT [ "/bin/bash", "-l" ]
