Split out handlers, updated output

Output aligned to docker structures

Signed-off-by: Jhon Honce <jhonce@redhat.com>

Refactored routing, added more endpoints and types

* Encapsulated all the routing information in the handler_* files.
* Added more serviceapi/types, including podman additions. See Info

Signed-off-by: Jhon Honce <jhonce@redhat.com>

Cleaned up code, implemented info content

* Move Content-Type check into serviceHandler
* Custom 404 handler showing the url, mostly for debugging
* Refactored images: better method names and explicit http codes
* Added content to /info
* Added podman fields to Info struct
* Added Container struct

Signed-off-by: Jhon Honce <jhonce@redhat.com>

Add a bunch of endpoints

containers: stop, pause, unpause, wait, rm
images: tag, rmi, create (pull only)

Signed-off-by: baude <bbaude@redhat.com>

Add even more handlers

* Add serviceapi/Error() to improve error handling
* Better support for API return payloads
* Renamed unimplemented to unsupported these are generic endpoints
  we don't intend to ever support.  Swarm broken out since it uses
  different HTTP codes to signal that the node is not in a swarm.
* Added more types
* API Version broken out so it can be validated in the future

pod create and container create

first pass at pod and container create.  the container create does not
quite work yet but it is very close.  pod create needs a partial
rewrite.  also broken off the DELETE (rm/rmi) to specific handler funcs.

Signed-off-by: baude <bbaude@redhat.com>

Add docker-py demos, GET .../containers/json

* Update serviceapi/types to reflect libpod not podman
* Refactored removeImage() to provide non-streaming return

  * .../containers/{name}/stats

Signed-off-by: Jhon Honce <jhonce@redhat.com>

Improve error handling

* Add check for at least one std stream required for /containers/{id}/logs
* Add check for state in /containers/{id}/top

serviceapi errors: append error message to API message

I dearly hope this is not breaking any other tests but debugging
"Internal Server Error" is not helpful to any user.  In case, it
breaks tests, we can rever the commit - that's why it's a small one.

Also remove the non-functional sub-Makefile.

Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

add make targets for testing the service

 * `sudo make run-service` for running the service.

 * `DOCKERPY_TEST="tests/integration/api_container_test.py::ListContainersTest" \
 	make run-docker-py-tests`
   for running a specific tests.  Run all tests by leaving the env
   variable empty.

Split handlers and server packages

The files were split to help contain bloat. The api/server package will
contain all code related to the functioning of the server while
api/handlers will have all the code related to implementing the end
points.

api/server/register_* will contain the methods for registering
endpoints.  Additionally, they will have the comments for generating the
swagger spec file.

See api/handlers/version.go for a small example handler,
api/handlers/containers.go contains much more complex handlers.

# uuid ![build status](https://travis-ci.org/google/uuid.svg?branch=master)
The uuid package generates and inspects UUIDs based on
[RFC 4122](http://tools.ietf.org/html/rfc4122)
and DCE 1.1: Authentication and Security Services.
This package is based on the github.com/pborman/uuid package (previously named
code.google.com/p/go-uuid). It differs from these earlier packages in that
a UUID is a 16 byte array rather than a byte slice. One loss due to this
change is the ability to represent an invalid UUID (vs a NIL UUID).
###### Install
`go get github.com/google/uuid`
###### Documentation
[![GoDoc](https://godoc.org/github.com/google/uuid?status.svg)](http://godoc.org/github.com/google/uuid)
Full `go doc` style documentation for the package can be viewed online without
installing this package by using the GoDoc site here:

======
[![GoDoc](https://godoc.org/github.com/gorilla/schema?status.svg)](https://godoc.org/github.com/gorilla/schema) [![Build Status](https://travis-ci.org/gorilla/schema.png?branch=master)](https://travis-ci.org/gorilla/schema)
[![Sourcegraph](https://sourcegraph.com/github.com/gorilla/schema/-/badge.svg)](https://sourcegraph.com/github.com/gorilla/schema?badge)
Package gorilla/schema converts structs to and from form values.
## Example
Here's a quick example: we parse POST form values and then decode them into a struct:
```go
// Set a Decoder instance as a package global, because it caches
// meta-data about structs, and an instance can be shared safely.
var decoder = schema.NewDecoder()
type Person struct {
Name string
Phone string
}
func MyHandler(w http.ResponseWriter, r *http.Request) {
err := r.ParseForm()
if err != nil {
// Handle error
}
var person Person
// r.PostForm is a map of our POST form values
err = decoder.Decode(&person, r.PostForm)
if err != nil {
// Handle error
}
// Do something with person.Name or person.Phone
}
```
Conversely, contents of a struct can be encoded into form values. Here's a variant of the previous example using the Encoder:
```go
var encoder = schema.NewEncoder()
func MyHttpRequest() {
person := Person{"Jane Doe", "555-5555"}
form := url.Values{}
err := encoder.Encode(person, form)
if err != nil {
// Handle error
}
// Use form values, for example, with an http client
client := new(http.Client)
res, err := client.PostForm("http://my-api.test", form)
}
```
To define custom names for fields, use a struct tag "schema". To not populate certain fields, use a dash for the name and it will be ignored:
```go
type Person struct {
Name string `schema:"name,required"` // custom name, must be supplied
Phone string `schema:"phone"` // custom name
Admin bool `schema:"-"` // this field is never set
}
```
The supported field types in the struct are:
* bool
* float variants (float32, float64)
* int variants (int, int8, int16, int32, int64)
* string
* uint variants (uint, uint8, uint16, uint32, uint64)
* struct
* a pointer to one of the above types
* a slice or a pointer to a slice of one of the above types
Unsupported types are simply ignored, however custom types can be registered to be converted.
More examples are available on the Gorilla website: https://www.gorillatoolkit.org/pkg/schema

Package gorilla/schema fills a struct with form values.
The basic usage is really simple. Given this struct:
type Person struct {
Name string
Phone string
}
...we can fill it passing a map to the Decode() function:
values := map[string][]string{
"Name": {"John"},
"Phone": {"999-999-999"},
}
person := new(Person)
decoder := schema.NewDecoder()
decoder.Decode(person, values)
This is just a simple example and it doesn't make a lot of sense to create
the map manually. Typically it will come from a http.Request object and
will be of type url.Values, http.Request.Form, or http.Request.MultipartForm:
func MyHandler(w http.ResponseWriter, r *http.Request) {
err := r.ParseForm()
if err != nil {
// Handle error
}
decoder := schema.NewDecoder()
// r.PostForm is a map of our POST form values
err := decoder.Decode(person, r.PostForm)
if err != nil {
// Handle error
}
// Do something with person.Name or person.Phone
}
Note: it is a good idea to set a Decoder instance as a package global,
because it caches meta-data about structs, and an instance can be shared safely:
var decoder = schema.NewDecoder()
To define custom names for fields, use a struct tag "schema". To not populate
certain fields, use a dash for the name and it will be ignored:
type Person struct {
Name string `schema:"name"` // custom name
Phone string `schema:"phone"` // custom name
Admin bool `schema:"-"` // this field is never set
}
The supported field types in the destination struct are:
* bool
* float variants (float32, float64)
* int variants (int, int8, int16, int32, int64)
* string
* uint variants (uint, uint8, uint16, uint32, uint64)
* struct
* a pointer to one of the above types
* a slice or a pointer to a slice of one of the above types
Non-supported types are simply ignored, however custom types can be registered
to be converted.
To fill nested structs, keys must use a dotted notation as the "path" for the
field. So for example, to fill the struct Person below:
type Phone struct {
Label string
Number string
}
type Person struct {
Name string
Phone Phone
}
...the source map must have the keys "Name", "Phone.Label" and "Phone.Number".
This means that an HTML form to fill a Person struct must look like this:
<form>
<input type="text" name="Name">
<input type="text" name="Phone.Label">
<input type="text" name="Phone.Number">
</form>
Single values are filled using the first value for a key from the source map.
Slices are filled using all values for a key from the source map. So to fill
a Person with multiple Phone values, like:
type Person struct {
Name string
Phones []Phone
}
...an HTML form that accepts three Phone values would look like this:
<form>
<input type="text" name="Name">
<input type="text" name="Phones.0.Label">
<input type="text" name="Phones.0.Number">
<input type="text" name="Phones.1.Label">
<input type="text" name="Phones.1.Number">
<input type="text" name="Phones.2.Label">
<input type="text" name="Phones.2.Number">
</form>
Notice that only for slices of structs the slice index is required.
This is needed for disambiguation: if the nested struct also had a slice
field, we could not translate multiple values to it if we did not use an
index for the parent struct.
There's also the possibility to create a custom type that implements the
TextUnmarshaler interface, and in this case there's no need to register
a converter, like:
type Person struct {
Emails []Email
}
type Email struct {
*mail.Address
}
func (e *Email) UnmarshalText(text []byte) (err error) {
e.Address, err = mail.ParseAddress(string(text))
return
}
...an HTML form that accepts three Email values would look like this:
<form>
<input type="email" name="Emails.0">
<input type="email" name="Emails.1">
<input type="email" name="Emails.2">
</form>
