Buildahcker

Buildahcker is a node.js library to create and run commands in OCI (Open Container Initiative) container images (or docker images), based on Buildah and a hash-based cache. It also contains utilities to easily create a partitioned bootable disk image of a Linux system.

Have a look to the API documentation here.

Installation

npm install buildahcker --save-dev

Usage

Here is a basic sample:

import {
  defaultContainerCache,
  ImageBuilder,
  run,
  addFiles,
  MemFile,
  DiskLocation,
} from "buildahcker";

const createImage = async () => {
  const builder = await ImageBuilder.from("alpine:latest", {
    logger: process.stdout,
    containerCache: defaultContainerCache(),
  });
  await builder.executeStep([
    run(["apk", "add", "--no-cache", "nginx"]),
    addFiles({
      "etc/issue": new MemFile({
        content: "Hello",
      }),
      app: new DiskLocation("./app", {
        overrideAttributes: { uid: 1, gid: 2 },
      }),
    }),
  ]);
  console.log("Created image: ", builder.imageId);
};

createImage();
