Docker template

This template installs Docker Engine and Docker Compose. Ubuntu starts the Docker daemon as a system service when the sandbox boots.

mjs

import { Sandbox, Template } from "@abox-dev/sdk";

const templateName = process.env.TEMPLATE_NAME ?? "docker-runtime";
const template = Template()
  .fromUbuntuImage("24.04")
  .aptInstall(["docker.io", "docker-compose-v2"])
  .runCmd("sudo docker pull alpine:3.22");

await Template.build(template, templateName, {
  cpuCount: 2,
  memoryMB: 2_048,
});

const sandbox = await Sandbox.create(templateName);
try {
  const result = await sandbox.commands.run(
    'sudo docker run --rm --network none alpine:3.22 echo "Hello from Docker" && sudo docker compose version',
  );
  console.log(result.stdout);
} finally {
  await sandbox.kill();
}

The Alpine image is pulled while the template is built. New sandboxes therefore start with the image already available. The example runs a container without a network and then prints the installed Compose version.

Rebuild the template when you need another base image or Docker package version.
