![logo](./tools/triton-text.png) # node-triton `triton` is a CLI tool for working with the CloudAPI for Joyent's Triton [Public Cloud] (https://docs.joyent.com/public-cloud) and [Private Cloud] (https://docs.joyent.com/private-cloud). CloudAPI is a RESTful API for end users of the cloud to manage their accounts, instances, networks, images, and to inquire other relevant details. CloudAPI provides a single view of docker containers, infrastructure containers and hardware virtual machines available in the Triton solution. There is currently another CLI tool known as [node-smartdc](https://github.com/joyent/node-smartdc) for CloudAPI. `node-smartdc` CLI works off the 32-character object UUID to uniquely identify object instances in API requests, and returns response payload in JSON format. The CLI covers both basic and advanced usage of [CloudAPI](https://apidocs.joyent.com/cloudapi/). As a lightweight programmable interface for CloudAPI, the `triton` CLI supports both name or UUID identification of object instances and the use of short ID, as well as the choice between concise tabular responses and full JSON responses. **The `triton` CLI is currently in beta and will be expanded over time to support all CloudAPI commands, eventually replacing `node-smartdc` as both the API client library for Triton cloud and the command line tool.** ## Setup ### User accounts, authentication, and security Before you can use the CLI you'll need an account on the cloud to which you are connecting and an SSH key uploaded. The SSH key is used to identify and secure SSH access to containers and other resources in Triton. If you do not already have an account on Joyent Public Cloud, sign up [here](https://www.joyent.com/public-cloud). ### API endpoint Each data center has a single CloudAPI endpoint. For Joyent Public Cloud, you can find the list of datacenters [here](https://docs.joyent.com/public-cloud/api-access/cloudapi#datacenter-urls). For private cloud implementations, please consult the private cloud operator for the correct URL. Have the URL handy as you'll need it in the next step. ### Installation 1. Install [node.js](http://nodejs.org/). 2. `npm install -g triton` Verify that it is installed and on your PATH: $ triton --version Triton CLI 1.0.0 Configure the proper environmental variables that correspond to the API endpoint and account, for example: SDC_URL=https://us-east-3b.api.joyent.com SDC_ACCOUNT=dave.eddy@joyent.com SDC_KEY_ID=04:0c:22:25:c9:85:d8:e4:fa:27:0d:67:94:68:9e:e9 ### Bash completion You can quickly source `triton` bash completions in your current shell with: source <(triton completion) For a more permanent installation: triton completion >> ~/.bashrc # Or maybe: triton completion > /usr/local/etc/bash_completion.d/triton ## `triton` CLI Usage ### Create and view instances $ triton instances SHORTID NAME IMG STATE PRIMARYIP AGO We have no instances created yet, so let's create some. In order to create an instance we need to specify two things: an image and a package. An image represents what will be used as the root of the instances filesystem, and the package represents the size of the instance, eg. ram, disk size, cpu shares, etc. More information on images and packages below - for now we'll just use SmartOS 64bit and a small 128M ram package which is a combo available on the Joyent Public Cloud. $ triton create-instance base-64 t4-standard-128M Without a name specified, the container created will have a generated ID. Now to create a container-native Ubuntu 14.04 container with 2GB of ram with the name "server-1" $ triton create-instance --name=server-1 ubuntu-14.04 t4-standard-2G Now list your instances again $ triton instances SHORTID NAME IMG STATE PRIMARYIP AGO 7db6c907 b851ba9 base-64@15.2.0 running 165.225.169.63 9m 9cf1f427 server-1 ubuntu-14.04@20150819 provisioning - 0s Get a quick overview of your account $ triton info login: dave.eddy@joyent.com name: Dave Eddy email: dave.eddy@joyent.com url: https://us-east-3b.api.joyent.com totalDisk: 50.5 GiB totalMemory: 2.0 MiB instances: 2 running: 1 provisioning: 1 To obtain more detailed information of your instance $ triton instance server-1 { "id": "9cf1f427-9a40-c188-ce87-fd0c4a5a2c2c", "name": "251d4fd", "type": "smartmachine", "state": "running", "image": "c8d68a9e-4682-11e5-9450-4f4fadd0936d", "ips": [ "165.225.169.54", "192.168.128.16" ], "memory": 2048, "disk": 51200, "metadata": { "root_authorized_keys": "(...ssh keys...)" }, "tags": {}, "created": "2015-09-08T04:56:27.734Z", "updated": "2015-09-08T04:56:43.000Z", "networks": [ "feb7b2c5-0063-42f0-a4e6-b812917397f7", "726379ac-358b-4fb4-bb7c-8bc4548bac1e" ], "dataset": "c8d68a9e-4682-11e5-9450-4f4fadd0936d", "primaryIp": "165.225.169.54", "firewall_enabled": false, "compute_node": "44454c4c-5400-1034-8053-b5c04f383432", "package": "t4-standard-2G" } ### SSH to an instance Connect to an instance over SSH $ triton ssh b851ba9 Last login: Wed Aug 26 17:59:35 2015 from 208.184.5.170 __ . . _| |_ | .-. . . .-. :--. |- |_ _| ;| || |(.-' | | | |__| `--' `-' `;-| `-' ' ' `-' / ; Instance (base-64 15.2.0) `-' https://docs.joyent.com/images/smartos/base [root@7db6c907-2693-42bc-ea9b-f38678f2554b ~]# uptime 20:08pm up 2:27, 0 users, load average: 0.00, 0.00, 0.01 [root@7db6c907-2693-42bc-ea9b-f38678f2554b ~]# logout Connection to 165.225.169.63 closed. Or non-interactively $ triton ssh b851ba9 uname -v joyent_20150826T120743Z ### Manage an instance Commonly used container operations are supported in the Triton CLI. More operations will be added to the list over time. $ triton help ... instance-audit List instance actions. start-instance (start) Start a single instance. stop-instance (stop) Stop a single instance. reboot-instance (reboot) Reboot a single instance. delete-instance (delete) Delete a single instance. wait-instance (wait) Wait on instances changing state. ... ### View packages and images Package definitions and images available vary between different datacenters and different Triton cloud implementations. To see all the packages offered in the datacenter and specific package information, use $ triton packages $ triton package ID|NAME Similarly, to find out the available images and their details, do $ triton images $ triton image ID|NAME Note that docker images are not shown in `triton images` as they are maintained in Docker Hub and other third-party registries configured to be used with Joyent's Triton clouds. **In general, docker containers should be provisioned and managed with the regular [`docker` CLI](https://docs.docker.com/installation/#installation)** (Triton provides an endpoint that represents the _entire datacenter_ as a single `DOCKER_HOST`. See the [Triton Docker documentation](https://apidocs.joyent.com/docker) for more information.) ## `TritonApi` Module Usage Node-triton can also be used as a node module for your own node.js tooling. A basic example: var triton = require('triton'); // See `createClient` block comment for full usage details: // https://github.com/joyent/node-triton/blob/master/lib/index.js var client = triton.createClient({ profile: { url: URL, account: ACCOUNT, keyId: KEY_ID } }); client.listImages(function (err, images) { client.close(); // Remember to close the client to close TCP conn. if (err) { console.error('listImages err:', err); } else { console.log(JSON.stringify(images, null, 4)); } }); ## Configuration This section defines all the vars in a TritonApi config. The baked in defaults are in "etc/defaults.json" and can be overriden for the CLI in "~/.triton/config.json". | Name | Description | | ---- | ----------- | | profile | The name of the triton profile to use. The default with the CLI is "env", i.e. take config from `SDC_*` envvars. | | cacheDir | The path (relative to the config dir, "~/.triton") where cache data is stored. The default is "cache", i.e. the `triton` CLI caches at "~/.triton/cache". | ## node-triton differences with node-smartdc - There is a single `triton` command instead of a number of `sdc-*` commands. - `TRITON_*` environment variables are preferred to the `SDC_*` environment variables. However the `SDC_*` envvars are still supported. ## cloudapi2.js differences with node-smartdc/lib/cloudapi.js The old node-smartdc module included an lib for talking directly to the SDC Cloud API (node-smartdc/lib/cloudapi.js). Part of this module (node-triton) is a re-write of the Cloud API lib with some backward incompatibilities. The differences and backward incompatibilities are discussed here. - Currently no caching options in cloudapi2.js (this should be re-added in some form). The `noCache` option to many of the cloudapi.js methods will not be re-added, it was a wart. - The leading `account` option to each cloudapi.js method has been dropped. It was redundant for the constructor `account` option. - "account" is now "user" in the CloudAPI constructor. - All (all? at least at the time of this writing) methods in cloudapi2.js have a signature of `function (options, callback)` instead of the sometimes haphazard extra arguments. ## Development Hooks Before commiting be sure to, at least: make check # lint and style checks make test-unit # run unit tests A good way to do that is to install the stock pre-commit hook in your clone via: make git-hooks Also please run the full (longer) test suite (`make test`). See the next section. ## Test suite node-triton has both unit tests (`make test-unit`) and integration tests (`make test-integration`). Integration tests require a config file, by default at "test/config.json". For example: $ cat test/config.json { "profileName": "east3b", "allowWriteActions": true, "image": "minimal-64", "package": "t4-standard-128M" } See "test/config.json.sample" for a description of all config vars. Minimally just a "profileName" or "profile" is required. Run all tests: make test You can use `TRITON_TEST_CONFIG` to override the test file, e.g.: $ cat test/coal.json { "profileName": "coal", "allowWriteActions": true } $ TRITON_TEST_CONFIG=test/coal.json make test where "coal" here refers to a development Triton (a.k.a SDC) ["Cloud On A Laptop"](https://github.com/joyent/sdc#getting-started) standup. ## License MPL 2.0
