A dockerode example using ES7 features. The script creates and starts a MongoDB container, then waits for 10 seconds and finally stops and deletes the container.

dockerode-example.js

const Docker = require('dockerode');

const localDocker = new Docker();

async function setup(hostPort) {
	const mongoContainer = await localDocker.createContainer({
		Image: 'mongo:4.0.0',
		Hostconfig: {
			PortBindings: {
				'27017/tcp': [{
					HostPort: hostPort,
				}],
			},
		},
		AttachStdin: false,
		AttachStdout: true,
		AttachStderr: true,
		Tty: true,
		OpenStdin: false,
		StdinOnce: false
	});
	return mongoContainer;
}

// Important: port MUST BE a string (Error: json: cannot unmarshal number into Go struct field PortBinding.HostPort of type string)
setup('12345')
	.then(container => container.start())
	.then((container) => {
		return new Promise(resolve => setTimeout(() => resolve(container), 10 * 1000));
	})
	.then(container => container.stop())
	.then(container => container.remove())
	.catch(err => console.error(err));

setup()
	.then(container => container.start())
	...
	.catch(err => console.error(err));

is needed since as of version 10.9.0 Node doesn't support aync/await syntax at the top level code block. 😄
