/*
* Core `TritonApi` client class. A TritonApi client object is a wrapper around
* a lower-level `CloudApi` client that makes raw calls to
* [Cloud API](https://apidocs.joyent.com/cloudapi/). The wrapper provides
* some conveniences, for example:
* - referring to resources by "shortId" (8-char UUID prefixes) or "name"
* (e.g. an VM instance has a unique name for an account, but the raw
* Cloud API only supports lookup by full UUID);
* - filling in of image details for instances which only have an "image_uuid"
* in Cloud API responses;
* - support for waiting for async operations to complete via "wait" parameters;
* - profile handling.
*
*
* Preparing a TritonApi is a three-step process. (Note: Some users might
* prefer to use the `createClient` convenience function in "index.js" that
* wraps up all three steps into a single call.)
*
* 1. Create the client object.
* 2. Initialize it (mainly involves finding the SSH key identified by the
* `keyId`).
* 3. Optionally, unlock the SSH key (if it is passphrase-protected and not in
* an ssh-agent). If you know that your key is not passphrase-protected
* or is an ssh-agent, then you can skip this step. The failure mode for
* a locked key looks like this:
* SigningError: error signing request: SSH private key id_rsa is locked (encrypted/password-protected). It must be unlocked before use.
* at SigningError._TritonBaseVError (/Users/trentm/tmp/node-triton/lib/errors.js:55:12)
* at new SigningError (/Users/trentm/tmp/node-triton/lib/errors.js:173:23)
* at CloudApi._getAuthHeaders (/Users/trentm/tmp/node-triton/lib/cloudapi2.js:185:22)
*
* # Usage
*
* var mod_triton = require('triton');
*
* // 1. Create the TritonApi instance.
* var client = mod_triton.createTritonApiClient({
* log: log,
* profile: profile, // See mod_triton.loadProfile
* config: config // See mod_triton.loadConfig
* });
*
* // 2. Call `init` to setup the profile. This involves finding the SSH
* // key identified by the profile's keyId.
* client.init(function (initErr) {
* if (initErr) boom(initErr);
*
* // 3. Unlock the SSH key, if necessary. Possibilities are:
* // (a) Skip this step. If the key is locked, you will get a
* // "SigningError" at first attempt to sign. See example above.
* // (b) The key is not locked.
* // `client.keyPair.isLocked() === false`
* // (c) You have a passphrase for the key:
* if (client.keyPair.isLocked()) {
* // This throws if the passphrase is incorrect.
* client.keyPair.unlock(passphrase);
* }
*
* // (d) Or you use a function that will prompt for a passphrase
* // and unlock with that. E.g., `promptPassphraseUnlockKey`
* // is one provided by this package that with prompt on stdin.
* mod_triton.promptPassphraseUnlockKey({
* tritonapi: client
* }, function (unlockErr) {
* if (unlockErr) boom(unlockErr);
2014-02-07 23:21:24 +02:00
*
* // 4. Now you can finally make an API call. For example:
* client.listImages(function (err, imgs) {
* // ...
* });
* });
* });
*
*
* # TritonApi method callback patterns
*
* Guidelines for the `cb` callback form for TritonApi methods are as follows:
*
* - Methods that delete a resource (i.e. call DELETE endpoints on cloudapi)
* should have a callback of one of the following forms:
* function (err)
* function (err, res) # if 'res' is useful to caller
* where `res` is the response object. The latter form is used if there
* is a reasonable use case for a caller needing it.
*
* - Other methods should have a callback of one of the following forms:
* function (err, theThing)
* function (err, theThing, res)
* function (err, _, res) # no meaningful body; useful 'res'
* function (err)
* `res` is the response object (from the original cloudapi request, in
* the case of methods that make an async request, and then poll waiting
* for completion). `theThing` is an endpoint-specific object. Typically it
* is the parsed JSON body from the cloudapi response. In some cases there
* is no meaningful response body (e.g. for RenameMachine), but the res can
* be useful. Here we use `_` to put a placeholder for the body, and keep
* `res` in the third position.
