deno-boxes

A small DSL for building Dockerfiles or Docker compose files.

Usage

Imports are available from:

deno.land: https://deno.land/x/boxes
nest.land: https://nest.land/package/boxes

Examples

Dockerfile

import * as c from "../containers/core.ts";

const base = new c.Base("hayd/alpine-deno", "1.8.1");

const container = new c.Container(base);

container.port(1993)
    .workdir("/app")
    .user("deno")
    .copy("example.js", ".")
    .run("deno cache example.js")
    .add(".", ".")
    .run("deno cache example.js")
    .cmd("run", "-A", "--unstable", "example.js");

console.log(container.render());

FROM hayd/alpine-deno:1.8.1
EXPOSE 1993
WORKDIR /app
USER deno
COPY example.js .
RUN deno cache example.js
ADD . .
RUN deno cache example.js
CMD ["run", "-A", "--unstable", "example.js"]

Composer file

import {Base, Container} from "../containers/core.ts";
import {Composer, Service} from "../containers/compose.ts";

const KAFKA_TAG = "0.19.0-kafka-2.5.0"
const KAKFA_FROM = "strimzi/kafka"
const KAKFA_BASE = new Base(KAKFA_FROM, KAFKA_TAG)

const zookeeper = new Container(KAKFA_BASE)
zookeeper.cmd("sh", "-c", "bin/zookeeper-server-start.sh config/zookeeper.properties")
    .port(2181)

const zkService = new Service("zookeeper", zookeeper)
zkService.env("LOG_DIR", "/tmp/")

const kafka = new Container(KAKFA_BASE)
kafka.cmd(
    "sh", "-c",
    "bin/kafka-server-start.sh config/server.properties --override listeners=$${KAFKA_LISTENERS} --override advertised.listeners=$${KAFKA_ADVERTISED_LISTENERS} --override zookeeper.connect=$${KAFKA_ZOOKEEPER_CONNECT}")
kafka.port(9092)
const kafkaService = new Service("kafka", kafka)

const ksEnv = {
    LOG_DIR: "/tmp/logs",
    KAFKA_ADVERTISED_LISTENERS: "PLAINTEXT://0.0.0.0:9092",
    KAFKA_LISTENERS: "PLAINTEXT://0.0.0.0:9092",
    KAFKA_ZOOKEEPER_CONNECT: "zookeeper:2181"
}

kafkaService.envs(ksEnv).depends_on(zkService)

const composer = new Composer()

composer.add(zkService).add(kafkaService)

console.log(composer.render())
