# node-triton
|
|
|
|
This repository is part of the Joyent Triton project. See the [contribution
|
|
guidelines](https://github.com/joyent/triton/blob/master/CONTRIBUTING.md) --
|
|
*Triton does not use GitHub PRs* -- and general documentation at the main
|
|
[Triton project](https://github.com/joyent/triton) page.
|
|
|
|
`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/).
|
|
|
|
**The `triton` CLI is currently in beta (effectively because it does not yet
|
|
have *complete* coverage of all commands from node-smartdc) 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 data centers [here](https://docs.joyent.com/public-cloud/data-centers).
|
|
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
|
|
|
|
Install Bash completion with
|
|
|
|
```bash
|
|
triton completion > /usr/local/etc/bash_completion.d/triton # Mac
|
|
triton completion > /etc/bash_completion.d/triton # Linux
|
|
```
|
|
|
|
Alternatively, if you don't have or don't want to use a "bash\_completion.d"
|
|
dir, then something like this would work:
|
|
|
|
```bash
|
|
triton completion > ~/.triton.completion
|
|
echo "source ~/.triton.completion" >> ~/.bashrc
|
|
```
|
|
|
|
Then open a new shell or manually `source FILE` that completion file, and
|
|
play with the bash completions:
|
|
|
|
triton <TAB>
|
|
|
|
|
|
## `triton` CLI Usage
|
|
|
|
### Create and view instances
|
|
|
|
$ triton instance list
|
|
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 instance create 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 instance create --name=server-1 ubuntu-14.04 t4-standard-2G
|
|
|
|
Now list your instances again
|
|
|
|
$ triton instance list
|
|
SHORTID NAME IMG STATE PRIMARYIP AGO
|
|

|
### Manage an instance
|
|
|
|
Commonly used container operations are supported in the Triton CLI:
|
|
|
|
$ triton help instance
|
|
...
|
|
list (ls) List instances.
|
|
get Get an instance.
|
|
create Create a new instance.
|
|
delete (rm) Delete one or more instances.
|
|
|
|
start Start one or more instances.
|
|
stop Stop one or more instances.
|
|
reboot Reboot one or more instances.
|
|
|
|
ssh SSH to the primary IP of an instance
|
|
wait Wait on instances changing state.
|
|
audit List instance actions.
|
|
|
|
### View packages and images
|
|
|
|
Package definitions and images available vary between different data centers
|
|
and different Triton cloud implementations.
|
|
|
|
To see all the packages offered in the data center and specific package
|
|
information, use
|
|
|
|
$ triton package list
|
|
$ triton package get ID|NAME
|
|
|
|
Similarly, to find out the available images and their details, do
|
|
|
|
$ triton image list
|
|
$ triton images 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" (on Windows: "%APPDATA%/Joyent/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.
|
|
- Node-smartdc still has more complete coverage of the Triton
|
|
[CloudAPI](https://apidocs.joyent.com/cloudapi/). However, `triton` is
|
|
catching up and is much more friendly to use.
|
|
|
|
|
|
## 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.
|
|
|
|
*Warning:* Running the *integration* tests will create resources and could
|
|
incur costs if running against a public cloud.
|
|
|
|
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.
