`triton` is a CLI tool for Joyent's Triton (a.k.a. SmartDataCenter), either for
|
||||
on-premises installations of Triton or Joyent's Public Cloud
|
||||
(<https://my.joyent.com>, <http://www.joyent.com/products/compute-service>).
|
||||
`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.
|
||||
|
||||
**This project aims to replace
|
||||
[node-smartdc](https://github.com/joyent/node-smartdc) as both the API
|
||||
client library for triton ([cloudapi](https://apidocs.joyent.com/cloudapi/))
|
||||
and the command line tool**
|
||||
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/).
|
||||
|
||||
## Installation
|
||||
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 git://github.com/joyent/node-triton`
|
||||
|
||||
Verify it installed and is on your PATH:
|
||||
Verify that it is installed and on your PATH:
|
||||
|
||||
$ triton --version
|
||||
joyent-triton 1.0.0
|
||||
Triton CLI 1.0.0
|
||||
|
||||
## Setup
|
||||
|
||||
Before you can use the CLI you'll need a Joyent account, an SSH key uploaded
|
||||
and `triton` configured with those account details.
|
||||
|
||||
1. Create a Joyent Public Cloud account here https://www.joyent.com/public-cloud
|
||||
2. Upload an SSH key (instructions on the site above)
|
||||
3. Set the proper environmental variables (instructions also above)
|
||||
|
||||
Example environmental variables
|
||||
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

and different Triton cloud implementation.

|

# Or maybe:
|
||||
triton completion > /usr/local/etc/bash_completion.d/triton
|
||||
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.)

## node-triton differences with node-smartdc
|
||||
|
||||
- There is a single `triton` command instead of a number of `sdc-*` commands.
|

- The `SDC_USER` envvar is accepted in preference to `SDC_ACCOUNT`.
