`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

Commonly used container operations are supported in the Triton CLI.
More operations will be added to the list over time.
source <(triton completion)

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.
...
For a more permanent installation:
### View packages and images
triton completion >> ~/.bashrc
Packages definitions and images available vary between different datacenters
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`.
- The `SDC_USER` env variable is accepted in preference to `SDC_ACCOUNT`.
