# Tips
## Implementing default logging and re-authentication attempts
You can implement custom logging and/or limit re-auth attempts by creating a custom HTTP client
like the following and setting it as the provider client's HTTP Client (via the
`gophercloud.ProviderClient.HTTPClient` field):
```go
//...
// LogRoundTripper satisfies the http.RoundTripper interface and is used to
// customize the default Gophercloud RoundTripper to allow for logging.
type LogRoundTripper struct {
rt http.RoundTripper
numReauthAttempts int
}
// newHTTPClient return a custom HTTP client that allows for logging relevant
// information before and after the HTTP request.
func newHTTPClient() http.Client {
return http.Client{
Transport: &LogRoundTripper{
rt: http.DefaultTransport,
},
}
}
// RoundTrip performs a round-trip HTTP request and logs relevant information about it.
func (lrt *LogRoundTripper) RoundTrip(request *http.Request) (*http.Response, error) {
glog.Infof("Request URL: %s\n", request.URL)
response, err := lrt.rt.RoundTrip(request)
if response == nil {
return nil, err
}
if response.StatusCode == http.StatusUnauthorized {
if lrt.numReauthAttempts == 3 {
return response, fmt.Errorf("Tried to re-authenticate 3 times with no success.")
}
lrt.numReauthAttempts++
}
glog.Debugf("Response Status: %s\n", response.Status)
return response, nil
}
endpoint := "https://127.0.0.1/auth"
pc := openstack.NewClient(endpoint)
pc.HTTPClient = newHTTPClient()
//...
```
## Implementing custom objects
OpenStack request/response objects may differ among variable names or types.
### Custom request objects
To pass custom options to a request, implement the desired `<ACTION>OptsBuilder` interface. For
example, to pass in
```go
type MyCreateServerOpts struct {
Name string
Size int
}
```
to `servers.Create`, simply implement the `servers.CreateOptsBuilder` interface:
```go
func (o MyCreateServeropts) ToServerCreateMap() (map[string]interface{}, error) {
return map[string]interface{}{
"name": o.Name,
"size": o.Size,
}, nil
}
```
create an instance of your custom options object, and pass it to `servers.Create`:
```go
// ...
myOpts := MyCreateServerOpts{
Name: "s1",
Size: "100",
}
server, err := servers.Create(computeClient, myOpts).Extract()
// ...
```
### Custom response objects
Some OpenStack services have extensions. Extensions that are supported in Gophercloud can be
combined to create a custom object:
```go
// ...
type MyVolume struct {
volumes.Volume
tenantattr.VolumeExt
}
var v struct {
MyVolume `json:"volume"`
}
err := volumes.Get(client, volID).ExtractInto(&v)
// ...
```
## Overriding default `UnmarshalJSON` method
For some response objects, a field may be a custom type or may be allowed to take on
different types. In these cases, overriding the default `UnmarshalJSON` method may be
necessary. To do this, declare the JSON `struct` field tag as "-" and create an `UnmarshalJSON`
method on the type:
```go
// ...
type MyVolume struct {
ID string `json: "id"`
TimeCreated time.Time `json: "-"`
}
func (r *MyVolume) UnmarshalJSON(b []byte) error {
type tmp MyVolume
var s struct {
tmp
TimeCreated gophercloud.JSONRFC3339MilliNoZ `json:"created_at"`
}
err := json.Unmarshal(b, &s)
if err != nil {
return err
}
*r = Volume(s.tmp)
r.TimeCreated = time.Time(s.CreatedAt)
return err
}
// ...
```

# Gophercloud: an OpenStack SDK for Go
[![Build Status](https://travis-ci.org/gophercloud/gophercloud.svg?branch=master)](https://travis-ci.org/gophercloud/gophercloud)
[![Coverage Status](https://coveralls.io/repos/github/gophercloud/gophercloud/badge.svg?branch=master)](https://coveralls.io/github/gophercloud/gophercloud?branch=master)
Gophercloud is an OpenStack Go SDK.
## Useful links
* [Reference documentation](http://godoc.org/github.com/gophercloud/gophercloud)
* [Effective Go](https://golang.org/doc/effective_go.html)
## How to install
Before installing, you need to ensure that your [GOPATH environment variable](https://golang.org/doc/code.html#GOPATH)
is pointing to an appropriate directory where you want to install Gophercloud:
```bash
mkdir $HOME/go
export GOPATH=$HOME/go
```
To protect yourself against changes in your dependencies, we highly recommend choosing a
[dependency management solution](https://github.com/golang/go/wiki/PackageManagementTools) for
your projects, such as [godep](https://github.com/tools/godep). Once this is set up, you can install
Gophercloud as a dependency like so:
```bash
go get github.com/gophercloud/gophercloud
# Edit your code to import relevant packages from "github.com/gophercloud/gophercloud"
godep save ./...
```
This will install all the source files you need into a `Godeps/_workspace` directory, which is
referenceable from your own source files when you use the `godep go` command.
## Getting started
### Credentials
Because you'll be hitting an API, you will need to retrieve your OpenStack
credentials and either store them as environment variables or in your local Go
files. The first method is recommended because it decouples credential
information from source code, allowing you to push the latter to your version
control system without any security risk.
You will need to retrieve the following:
* username
* password
* a valid Keystone identity URL
For users that have the OpenStack dashboard installed, there's a shortcut. If
you visit the `project/access_and_security` path in Horizon and click on the
"Download OpenStack RC File" button at the top right hand corner, you will
download a bash file that exports all of your access details to environment
variables. To execute the file, run `source admin-openrc.sh` and you will be
prompted for your password.
### Authentication
Once you have access to your credentials, you can begin plugging them into
Gophercloud. The next step is authentication, and this is handled by a base
"Provider" struct. To get one, you can either pass in your credentials
explicitly, or tell Gophercloud to use environment variables:
```go
import (
"github.com/gophercloud/gophercloud"
"github.com/gophercloud/gophercloud/openstack"
"github.com/gophercloud/gophercloud/openstack/utils"
)
// Option 1: Pass in the values yourself
opts := gophercloud.AuthOptions{
IdentityEndpoint: "https://openstack.example.com:5000/v2.0",
Username: "{username}",
Password: "{password}",
}
// Option 2: Use a utility function to retrieve all your environment variables
opts, err := openstack.AuthOptionsFromEnv()
```
Once you have the `opts` variable, you can pass it in and get back a
`ProviderClient` struct:
```go
provider, err := openstack.AuthenticatedClient(opts)
```
The `ProviderClient` is the top-level client that all of your OpenStack services
derive from. The provider contains all of the authentication details that allow
your Go code to access the API - such as the base URL and token ID.
### Provision a server
Once we have a base Provider, we inject it as a dependency into each OpenStack
service. In order to work with the Compute API, we need a Compute service
client; which can be created like so:
```go
client, err := openstack.NewComputeV2(provider, gophercloud.EndpointOpts{
Region: os.Getenv("OS_REGION_NAME"),
})
```
We then use this `client` for any Compute API operation we want. In our case,
we want to provision a new server - so we invoke the `Create` method and pass
in the flavor ID (hardware specification) and image ID (operating system) we're
interested in:
```go
import "github.com/gophercloud/gophercloud/openstack/compute/v2/servers"
server, err := servers.Create(client, servers.CreateOpts{
Name: "My new server!",
FlavorRef: "flavor_id",
ImageRef: "image_id",
}).Extract()
```
The above code sample creates a new server with the parameters, and embodies the
new resource in the `server` variable (a
[`servers.Server`](http://godoc.org/github.com/gophercloud/gophercloud) struct).
## Advanced Usage
Have a look at the [FAQ](./FAQ.md) for some tips on customizing the way Gophercloud works.
## Backwards-Compatibility Guarantees
None. Vendor it and write tests covering the parts you use.

## On Pull Requests
- Before you start a PR there needs to be a Github issue and a discussion about it
on that issue with a core contributor, even if it's just a 'SGTM'.
- A PR's description must reference the issue it closes with a `For <ISSUE NUMBER>` (e.g. For #293).
- A PR's description must contain link(s) to the line(s) in the OpenStack
source code (on Github) that prove(s) the PR code to be valid. Links to documentation
are not good enough. The link(s) should be to a non-`master` branch. For example,
a pull request implementing the creation of a Neutron v2 subnet might put the
following link in the description:
https://github.com/openstack/neutron/blob/stable/mitaka/neutron/api/v2/attributes.py#L749
From that link, a reviewer (or user) can verify the fields in the request/response
objects in the PR.
- A PR that is in-progress should have `[wip]` in front of the PR's title. When
ready for review, remove the `[wip]` and ping a core contributor with an `@`.
- Forcing PRs to be small can have the effect of users submitting PRs in a hierarchical chain, with
one depending on the next. If a PR depends on another one, it should have a [Pending #PRNUM]
prefix in the PR title. In addition, it will be the PR submitter's responsibility to remove the
[Pending #PRNUM] tag once the PR has been updated with the merged, dependent PR. That will
let reviewers know it is ready to review.
- A PR should be small. Even if you intend on implementing an entire
service, a PR should only be one route of that service
(e.g. create server or get server, but not both).
- Unless explicitly asked, do not squash commits in the middle of a review; only
append. It makes it difficult for the reviewer to see what's changed from one
review to the next.
## On Code
- In re design: follow as closely as is reasonable the code already in the library.
Most operations (e.g. create, delete) admit the same design.
- Unit tests and acceptance (integration) tests must be written to cover each PR.
Tests for operations with several options (e.g. list, create) should include all
the options in the tests. This will allow users to verify an operation on their
own infrastructure and see an example of usage.
- If in doubt, ask in-line on the PR.
### File Structure
- The following should be used in most cases:
- `requests.go`: contains all the functions that make HTTP requests and the
types associated with the HTTP request (parameters for URL, body, etc)
- `results.go`: contains all the response objects and their methods
- `urls.go`: contains the endpoints to which the requests are made
### Naming
- For methods on a type in `response.go`, the receiver should be named `r` and the
variable into which it will be unmarshalled `s`.
- Functions in `requests.go`, with the exception of functions that return a
`pagination.Pager`, should be named returns of the name `r`.
- Functions in `requests.go` that accept request bodies should accept as their
last parameter an `interface` named `<Action>OptsBuilder` (eg `CreateOptsBuilder`).
This `interface` should have at the least a method named `To<Resource><Action>Map`
(eg `ToPortCreateMap`).
- Functions in `requests.go` that accept query strings should accept as their
last parameter an `interface` named `<Action>OptsBuilder` (eg `ListOptsBuilder`).
This `interface` should have at the least a method named `To<Resource><Action>Query`
(eg `ToServerListQuery`).

/*
Package gophercloud provides a multi-vendor interface to OpenStack-compatible
clouds. The library has a three-level hierarchy: providers, services, and
resources.
Provider structs represent the service providers that offer and manage a
collection of services. The IdentityEndpoint is typically refered to as
"auth_url" in information provided by the cloud operator. Additionally,
the cloud may refer to TenantID or TenantName as project_id and project_name.
These are defined like so:
opts := gophercloud.AuthOptions{
IdentityEndpoint: "https://openstack.example.com:5000/v2.0",
Username: "{username}",
Password: "{password}",
TenantID: "{tenant_id}",
}
provider, err := openstack.AuthenticatedClient(opts)
Service structs are specific to a provider and handle all of the logic and
operations for a particular OpenStack service. Examples of services include:
Compute, Object Storage, Block Storage. In order to define one, you need to
pass in the parent provider, like so:
opts := gophercloud.EndpointOpts{Region: "RegionOne"}
client := openstack.NewComputeV2(provider, opts)
Resource structs are the domain models that services make use of in order
to work with and represent the state of API resources:
server, err := servers.Get(client, "{serverId}").Extract()
Intermediate Result structs are returned for API operations, which allow
generic access to the HTTP headers, response body, and any errors associated
with the network transaction. To turn a result into a usable resource struct,
you must call the Extract method which is chained to the response, or an
Extract function from an applicable extension:
result := servers.Get(client, "{serverId}")
// Attempt to extract the disk configuration from the OS-DCF disk config
// extension:
config, err := diskconfig.ExtractGet(result)
All requests that enumerate a collection return a Pager struct that is used to
iterate through the results one page at a time. Use the EachPage method on that
Pager to handle each successive Page in a closure, then use the appropriate
extraction method from that request's package to interpret that Page as a slice
of results:
err := servers.List(client, nil).EachPage(func (page pagination.Page) (bool, error) {
s, err := servers.ExtractServers(page)
if err != nil {
return false, err
}
// Handle the []servers.Server slice.
// Return "false" or an error to prematurely stop fetching new pages.
return true, nil
})
This top-level package contains utility functions and data types that are used
throughout the provider and service packages. Of particular note for end users
are the AuthOptions and EndpointOpts structs.

It accepts an arbitrary tagged structure and produces a string map that's
suitable for use as the HTTP headers of an outgoing request. Field names are
mapped to header names based in "h" tags.
type struct Something {
Bar string `h:"x_bar"`
Baz int `h:"lorem_ipsum"`
}
instance := Something{
Bar: "AAA",
Baz: "BBB",
}
will be converted into:
map[string]string{
"x_bar": "AAA",
"lorem_ipsum": "BBB",
}
Untagged fields and fields left at their zero values are skipped. Integers,
booleans and string values are supported.

// Package suite contains logic for creating testing suite structs
// and running the methods on those structs as tests. The most useful
// piece of this package is that you can create setup/teardown methods
// on your testing suites, which will run before/after the whole suite
// or individual tests (depending on which interface(s) you
// implement).
//
// A testing suite is usually built by first extending the built-in
// suite functionality from suite.Suite in testify. Alternatively,
// you could reproduce that logic on your own if you wanted (you
// just need to implement the TestingSuite interface from
// suite/interfaces.go).
//
// After that, you can implement any of the interfaces in
// suite/interfaces.go to add setup/teardown functionality to your
// suite, and add any methods that start with "Test" to add tests.
// Methods that do not match any suite interfaces and do not begin
// with "Test" will not be run by testify, and can safely be used as
// helper methods.
//
// Once you've built your testing suite, you need to run the suite
// (using suite.Run from testify) inside any function that matches the
// identity that "go test" is already looking for (i.e.
// func(*testing.T)).
//
// Regular expression to select test suites specified command-line
// argument "-run". Regular expression to select the methods
// of test suites specified command-line argument "-m".
// Suite object has assertion methods.
//
// A crude example:
// // Basic imports
// import (
// "testing"
// "github.com/stretchr/testify/assert"
// "github.com/stretchr/testify/suite"
// )
//
// // Define the suite, and absorb the built-in basic suite
// // functionality from testify - including a T() method which
// // returns the current testing context
// type ExampleTestSuite struct {
// suite.Suite
// VariableThatShouldStartAtFive int
// }
//
// // Make sure that VariableThatShouldStartAtFive is set to five
// // before each test
// func (suite *ExampleTestSuite) SetupTest() {
// suite.VariableThatShouldStartAtFive = 5
// }
//
// // All methods that begin with "Test" are run as tests within a
// // suite.
// func (suite *ExampleTestSuite) TestExample() {
// assert.Equal(suite.T(), 5, suite.VariableThatShouldStartAtFive)
// suite.Equal(5, suite.VariableThatShouldStartAtFive)
// }
//
// // In order for 'go test' to run this suite, we need to create
// // a normal test function and pass our suite to suite.Run
// func TestExampleTestSuite(t *testing.T) {
// suite.Run(t, new(ExampleTestSuite))
// }
