# triton-go
|
||
|
|
||
|
`go-triton` is an idiomatic library exposing a client SDK for Go applications using the Joyent Triton API.
|
||
|
|
||
|
## Usage
|
||
|
|
||
|
Triton uses [HTTP Signature][4] to sign the Date header in each HTTP request made to the Triton API. Currently, requests can be signed using either a private key file loaded from disk (using an [`authentication.PrivateKeySigner`][5]), or using a key stored with the local SSH Agent (using an [`SSHAgentSigner`][6].
|
||
|
|
||
|
To construct a Signer, use the `New*` range of methods in the `authentication` package. In the case of `authentication.NewSSHAgentSigner`, the parameters are the fingerprint of the key with which to sign, and the account name (normally stored in the `SDC_ACCOUNT` environment variable). For example:
|
||
|
|
||
|
```
|
||
|
const fingerprint := "a4:c6:f3:75:80:27:e0:03:a9:98:79:ef:c5:0a:06:11"
|
||
|
sshKeySigner, err := authentication.NewSSHAgentSigner(fingerprint, "AccountName")
|
||
|
if err != nil {
|
||
|
log.Fatalf("NewSSHAgentSigner: %s", err)
|
||
|
}
|
||
|
```
|
||
|
|
||
|
An appropriate key fingerprint can be generated using `ssh-keygen`:
|
||
|
|
||
|
```
|
||
|
ssh-keygen -Emd5 -lf ~/.ssh/id_rsa.pub | cut -d " " -f 2 | sed 's/MD5://'
|
||
|
```
|
||
|
|
||
|
To construct a Client, use the `NewClient` function, passing in the endpoint, account name and constructed signer:
|
||
|
|
||
|
```go
|
||
|
client, err := triton.NewClient("https://us-sw-1.api.joyent.com/", "AccountName", sshKeySigner)
|
||
|
if err != nil {
|
||
|
log.Fatalf("NewClient: %s", err)
|
||
|
}
|
||
|
```
|
||
|
|
||
|
Having constructed a `triton.Client`, use the methods available to access functionality by functional grouping. For example, for access to operations on SSH keys, use the `Keys()` method to obtain a client which has access to the `CreateKey`, `ListKeys` and `DeleteKey` operations. For access to operations on Machines, use the `Machines()` method to obtain a client which has access to the `RenameMachine`, `GetMachineMetadata`, `GetMachineTag`, and other operations.
|
||
|
|
||
|
Operation methods take their formal parameters via a struct named `OperationInput` - for example when creating an SSH key, the `CreateKeyInput` struct is used with the `func CreateKey(*CreateKeyInput) (*Key, error)` method. This allows specification of named parameters:
|
||
|
|
||
|
```
|
||
|
client := state.Client().Keys()
|
||
|
|
||
|
key, err := client.CreateKey(&CreateKeyInput{
|
||
|
Name: "tempKey",
|
||
|
Key: "ssh-rsa .....",
|
||
|
})
|
||
|
if err != nil {
|
||
|
panic(err)
|
||
|
}
|
||
|
|
||
|
// Key contains the return value.
|
||
|
```
|
||
|
|
||
|
## Error Handling
|
||
|
|
||
|
If an error is returned by the HTTP API, the `error` returned from the function will contain an instance of `triton.TritonError` in the chain. Error wrapping is performed using the [errwrap][7] library from HashiCorp.
|
||
|
|
||
|

## Running Acceptance Tests
|
||
|
|
||
|
Acceptance Tests run directly against the Triton API, so you will need either a local installation or Triton or an account with Joyent in order to run them. The tests create real resources (and thus cost real money!)
|
||
|
|
||
|
In order to run acceptance tests, the following environment variables must be set:
|
||
|
|
||
|
- `TRITON_TEST` - must be set to any value in order to indicate desire to create resources
|
||
|
- `SDC_URL` - the base endpoint for the Triton API
|
||
|
- `SDC_ACCOUNT` - the account name for the Triton API
|
||
|
- `SDC_KEY_ID` - the fingerprint of the SSH key identifying the key
|
||
|
|
||
|
Additionally, you may set `SDC_KEY_MATERIAL` to the contents of an unencrypted private key. If this is set, the PrivateKeySigner (see above) will be used - if not the SSHAgentSigner will be used.
|
||
|
|
||
|
