Docker API NodeJS

Since docker-modem is not really useable currently especially with the new cluster volumes, this project aims to integrate all of the features that docker-modem does not.

Usage

Setup

import { Modem } from "docker-api-nodejs";

const modem = new Modem(<path-to-docker-socket>);

Model

The project uses the responses from docker in a handle model. That means that for a basic request such as listing object like volumes you will get the exact same response as you would when you call the socket directly.

If you want to list objects you would call the list function of the corresponding interface.

For example if you want to list all local volumes or clusterVolumes:

const list = await Volumes.list(<modem>, <filterMap>);
const clusterList = await Volumes.listCluster(<modem>, <filterMap>);

The parameter "filterMap" refers to a map object that maps a string key to an array of string values (for more infos see official docker api documentation).

Hoever if you want to get specific information on an object e.g. inspecting its content more closely you can create a handle for that object like so:

Handle for a volume:

const volumeHandle = VolumeHandle.fromVolume(<modem>, <volume-object>);
const clusterVolumeHandle = Volumes.getClusterHandle(<modem>, <name of the clusterVolume>);

const handle = NodeHandle.fromNode(<modem>, <node-object>);
const handle = Nodes.getHandle(<modem>, <node-object-id>)

It may be needed to cast these ids to their respective types.

Create functions always return a handle on that specifc object, for example:

const handle = await Configs.create(<modem>, <configSpec>);

From there on you can (if the object supports it) inspect, remove, update, ...

The parameters for every operation are based on the official docker api documentation

Stacks

Stacks are handled a little different as there is no endpoint in the docker socket to connect to. See here for more details

Testing

Testing assumes a clean docker environment with no objects other than the standard. So if you want to test the project keep that in mind
