Build Status NPM Downloads NPM Version Issues License

Docker Hub API is an API library written for NodeJS to access the official Docker Hub/Registry.

Install

To install this package into your project simply run the following:

npm install --save docker-hub-api

Once installed you can start to use this package by requiring the module:

let dockerHubAPI = require('docker-hub-api');

Caching

This package will be default cache all calls to the same resource for 5 minutes so that calls to the same resource returning the same data will not re query the Docker Hub API.

This can be turned off or the expire time adjusted by adding the following code:

let dockerHubAPI = require('docker-hub-api');
dockerHubAPI.setCacheOptions({enabled: true, time: 60}); // This will enable the cache and cache things for 60 seconds

Logging In

In order to access authenticated routes of the API you must login.

There are 2 methods available to do that.

login(username, password)

This method logs in via the API and gets a login token for your account.

For security purposes you should make sure to never commit any code with login details. Using environment variables is one way to get around that:

let dockerHubAPI = require('docker-hub-api');
dockerHubAPI.login(process.env.DOCKER_HUB_USERNAME, process.env.DOCKER_HUB_PASSWORD);

The login method also returns the response from Docker Hub which includes the login token if you wish to get that token:

let dockerHubAPI = require('docker-hub-api');
dockerHubAPI.login(process.env.DOCKER_HUB_USERNAME, process.env.DOCKER_HUB_PASSWORD).then(function(info) {
    console.log(`My Docker Hub login token is '${info.token}'!`);
});

setLoginToken(token)

This works similar to above, but uses an existing login token so that you don't need to make a login request.

Again like above, you should move this off to an environment variable and never expose it:

let dockerHubAPI = require('docker-hub-api');
dockerHubAPI.setLoginToken(process.env.DOCKER_HUB_LOGIN_TOKEN);

Usage

This is a complete list of methods available from this package. All methods return ES6 promises.

There are 2 types of requests. Authenticated requests and non authenticated requests. As the names suggest, authenticated requests require you to have authenticated/logged in with Docker Hub.

Non Authenticated Requests

These requests require no authentication and can be made right away with no issues.

comments(username, repository, options)

This gets the comments for a given repository/user combination. As per the repository method above, if the username is left out, it will query the official repository.

You can also pass in options to limit the number of results per page and the page to go to like so:

{
    perPage: 10,
    page: 4
}

Below is an example of what's returned:

    }
}

buildHistory(username, repository, options)

This gets the build history for a given repository/user combination.

You can also pass in options to limit the number of results per page and the page to go to like so:

{
    perPage: 10,
    page: 4
}

Below is an example of what's returned:

[
    {
        "id": 3333420,
        "status": 10,
        "created_date": "2016-01-28T09:44:47.667135Z",
        "last_updated": "2016-01-28T09:55:56.381992Z",
        "build_code": "bhgpwqvc69xxhqnqnxukurq",
        "dockertag_name": "latest",
        "cause": null
    },
    {
        "id": 3333355,
        "status": -1,
        "created_date": "2016-01-28T09:39:11.261907Z",
        "last_updated": "2016-01-28T09:43:27.832295Z",

        "dockertag_name": "latest",
        "cause": null
    }
]

The status refers to the outcome of the build where:

  • -1 means it failed
  • 10 means it succeeded

There may be other status codes but those are the ones I'm aware of.

I'm unaware of any cases where cause doesn't equal null.

buildLinks(username, repository)

This gets the build links for a given repository/user combination.

Below is an example of what's returned:

[
    {
        "id": 12959,

        "to_repo": "maven"
    }
]

buildSettings(username, repository)

This gets the build settings for a given repository/user combination. This doesn't include links or build triggers.

Below is an example of what's returned:

{
    "repository": 501609,
    "build_name": "RyanTheAllmighty/docker-maven-custom",
    "provider": "github",
    "source_url": "https://github.com/RyanTheAllmighty/docker-maven-custom.git",
    "docker_url": "ryantheallmighty/maven-custom",

        {
            "id": 213846,
            "name": "{sourceref}",
            "dockerfile_location": "/",
            "source_name": "/^([^m]|.[^a]|..[^s]|...[^t]|....[^e]|.....[^r]|.{0,5}$|.{7,})/",
            "source_type": "Branch"
        },

    "token": "UUID-HERE",
    "active": true,
    "trigger_url": "https://registry.hub.docker.com/u/ryantheallmighty/maven-custom/trigger/UUID-HERE/"
}

buildTriggerHistory(username, repository)

This gets the build triggers for a given repository/user combination.

Below is an example of what's returned:

[
    {
        "ip_address": "203.219.62.185                         ",
        "result": "triggered",
        "result_desc": "Build Triggered",
        "user_agent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/48.0.2564.109 Safari/537.36",
        "request_body": null,

        "build_code": "bqxx7gwbqgbn9pvs72vthnz"
    }
]

In my testing the ip_address filed contained a large amount of whitespace after the actual IP address. I've left this in as Docker Hub returns it, so you may wish to do your own trimming.

collaborators(username, repository)

This gets the collaborators for a given repository/user combination.

Below is an example of what's returned:

[
    {
        "user": "ryantheallmighty"
    }
]

createBuildLink(username, repository, to_repo)

This creates a build link to a given repository to the given to_repo which should be in format 'username/repository' or just 'repository' for official repositories.

Below is an example of what's returned:

{
    "id": 13924,
    "from_repo": "ryantheallmighty/maven-custom",
    "to_repo": "debian"
}

createBuildTag(username, repository, details)

This creates a build tag to a given repository.

Passing in an object with the details:

{
    dockerfile_location: '/'
    name: 'tag-name'
    source_name: 'master'
    source_type: 'Branch'
}

You may leave out the dockerfile_location and it will default to '/' and the same for name which will default to 'latest'.

source_type is either Branch or Tag and source_name should be the name of the tag or branch to build from. source_type will default to 'Branch' if left out.

Below is an example of what's returned:

{
    "id": 228073,
    "name": "tag-name",
    "dockerfile_location": "/",
    "source_name": "master",
    "source_type": "Branch"
}

            "source_type": "Branch",
            "source_name": "master",
            "dockerfile_location": "/"
        },
        {
            "name": "test",
            "source_type": "Branch",
            "source_name": "test",
            "dockerfile_location": "/"

            "dockerfile_location": "/",
            "source_name": "test",
            "source_type": "Branch"
        },
        {

You may leave out the dockerfile_location and it will default to '/'.

source_type is either Branch or Tag and source_name should be the name of the tag or branch to build from. source_name will default to 'master' and source_type will default to 'Branch' if left out.

Below is an example of what's returned:

{
    "id": 213845,
    "name": "latest",
    "dockerfile_location": "/",
    "source_name": "master",
    "source_type": "Branch"
}

Please note that trying to trigger a build with details which don't match any of the repositories build tags will have no effect and will return an empty array.

setRepositoryDescription(username, name, descriptions)

This sets one or both of the descriptions for a repository you own.

Passing in an object with the short, full, or both descriptions:

{
    short: "A short description",
    full: "A full description"
}

This returns the same information as repository(username, name).

starRepository(username, name)

This stars a given repository.

This method returns nothing on success, but an error in the .catch() block of the promise indicates an error there.

triggerBuild(username, repository, details)

This triggers a build of the repository.

Passing in an object with the details:

{
    dockerfile_location: '/'
    source_name: 'master'
    source_type: 'Branch'
}

You may leave out the dockerfile_location and it will default to '/'.

source_type is either Branch or Tag and source_name should be the name of the tag or branch to build from. source_name will default to 'master' and source_type will default to 'Branch' if left out.

Below is an example of what's returned:

[
    {
        "source_type": "Branch",
        "source_name": "test",
        "evaluated_tag_name": "latest",
        "build_code": "bpzaqzu4nxpypzjren5vapt",
        "msg": "Build submitted",
        "queued_for_retry": false
    }
]

Please note that trying to trigger a build with details which don't match any of the repositories build tags will have no effect and will return an empty array.

unstarRepository(username, name)

This unstars a given repository.

This method returns nothing on success, but an error in the .catch() block of the promise indicates an error there.

webhooks(username, name, options)

This gets the webhooks for a repository you own.

You can also pass in options to limit the number of results per page and the page to go to like so:

{
    perPage: 10,
    page: 4
}

Below is an example of what's returned:

[
    {
        "id": 8550,
        "name": "Test",
        "active": true,
        "expect_final_callback": true,
        "creator": "ryantheallmighty",
        "last_updated": "2015-12-12T11:19:08.163295Z",
        "last_updater": "ryantheallmighty",
        "hooks": [
            {
                "id": 10014,
                "creator": "ryantheallmighty",
                "last_updater": "ryantheallmighty",
                "hook_url": "https://www.example.com",
                "date_added": "2015-12-12T11:19:08.474922Z",
                "last_updated": "2015-12-12T11:19:08.477809Z",
                "active": true
            }
        ]
    }
]

Testing & Linting

To run this applications tests and linter, simply install Gulp globally with the below command:

npm install -g gulp

Then run the following command in the directory this repository was cloned into:

gulp

The gulpfile gives access to a few methods shown below:

  • jscs: Runs the JSCS tool to check JS code.
  • jshint: Runs the JSHint tool to check JS code.
  • test: Runs the mocha tests.
  • style: Runs the jscs and jshint tasks to check JS code.
  • watch: Runs all 3 main tasks and then watches for file changes to rerun those tasks constantly as files are changed.

By default Gulp is set to run the jscs, jshint and test tasks when no arguments are provided to it.

Note about authentication

The tests will test authenticated routes which require access to three environment variables to work correctly:

  • DOCKER_HUB_USERNAME
  • DOCKER_HUB_PASSWORD
  • DOCKER_HUB_LOGIN_TOKEN

The values for these should be pretty straight forward besides the DOCKER_HUB_LOGIN_TOKEN which is a JWT token sent by Docker HUB after a login.

The best way to retrieve it is to check your browsers cookies for 'https://hub.docker.com' and copy the contents of the cookie named 'jwt'.
