* Add Virtual Kubelet provider for VIC Initial virtual kubelet provider for VMware VIC. This provider currently handles creating and starting of a pod VM via the VIC portlayer and persona server. Image store handling via the VIC persona server. This provider currently requires the feature/wolfpack branch of VIC. * Added pod stop and delete. Also added node capacity. Added the ability to stop and delete pod VMs via VIC. Also retrieve node capacity information from the VCH. * Cleanup and readme file Some file clean up and added a Readme.md markdown file for the VIC provider. * Cleaned up errors, added function comments, moved operation code 1. Cleaned up error handling. Set standard for creating errors. 2. Added method prototype comments for all interface functions. 3. Moved PodCreator, PodStarter, PodStopper, and PodDeleter to a new folder. * Add mocking code and unit tests for podcache, podcreator, and podstarter Used the unit test framework used in VIC to handle assertions in the provider's unit test. Mocking code generated using OSS project mockery, which is compatible with the testify assertion framework. * Vendored packages for the VIC provider Requires feature/wolfpack branch of VIC and a few specific commit sha of projects used within VIC. * Implementation of POD Stopper and Deleter unit tests (#4) * Updated files for initial PR
Objx
Objx - Go package for dealing with maps, slices, JSON and other data.
Get started:
- Install Objx with one line of code, or update it with another
- Check out the API Documentation http://godoc.org/github.com/stretchr/objx
Overview
Objx provides the objx.Map type, which is a map[string]interface{} that exposes a powerful Get method (among others) that allows you to easily and quickly get access to data within the map, without having to worry too much about type assertions, missing data, default values etc.
Pattern
Objx uses a preditable pattern to make access data from within map[string]interface{} easy. Call one of the objx. functions to create your objx.Map to get going:
m, err := objx.FromJSON(json)
NOTE: Any methods or functions with the Must prefix will panic if something goes wrong, the rest will be optimistic and try to figure things out without panicking.
Use Get to access the value you're interested in. You can use dot and array
notation too:
m.Get("places[0].latlng")
Once you have sought the Value you're interested in, you can use the Is* methods to determine its type.
if m.Get("code").IsStr() { // Your code... }
Or you can just assume the type, and use one of the strong type methods to extract the real value:
m.Get("code").Int()
If there's no value there (or if it's the wrong type) then a default value will be returned, or you can be explicit about the default value.
Get("code").Int(-1)
If you're dealing with a slice of data as a value, Objx provides many useful methods for iterating, manipulating and selecting that data. You can find out more by exploring the index below.
Reading data
A simple example of how to use Objx:
// Use MustFromJSON to make an objx.Map from some JSON
m := objx.MustFromJSON(`{"name": "Mat", "age": 30}`)
// Get the details
name := m.Get("name").Str()
age := m.Get("age").Int()
// Get their nickname (or use their name if they don't have one)
nickname := m.Get("nickname").Str(name)
Ranging
Since objx.Map is a map[string]interface{} you can treat it as such. For example, to range the data, do what you would expect:
m := objx.MustFromJSON(json)
for key, value := range m {
// Your code...
}
Installation
To install Objx, use go get:
go get github.com/stretchr/objx
Staying up to date
To update Objx to the latest version, run:
go get -u github.com/stretchr/objx
Supported go versions
We support the lastest two major Go versions, which are 1.8 and 1.9 at the moment.
