GoIsilon

Overview

GoIsilon is a Go package that provides a client for the EMC Isilon OneFS HTTP API. The package provides both direct implementations of the API bindings as well as abstract, helper functionality. In addition, services such as Docker, Mesos, and REX-Ray use the GoIsilon package to integrate with the NAS storage platform.

OneFS API Support Matrix

The GoIsilon package is tested with and supports OneFS 8.1+.

Examples

The tests provide working examples for how to use the package, but here are a few code snippets to further illustrate the basic ideas:

Initialize a new client

This example shows how to initialize a new client.

client, err := NewClient(context.Background())
if err != nil {
	panic(err)
}

Please note that there is no attempt to provide a host, credentials, or any other options. The NewClient() function relies on the following environment variables to configure the GoIsilon client:

Environment Variables

Name	Description
`GOISILON_ENDPOINT`	the API endpoint, ex. `https://172.17.177.230:8080`
`GOISILON_USERNAME`	the username
`GOISILON_GROUP`	the user's group
`GOISILON_PASSWORD`	the password
`GOISILON_INSECURE`	whether to skip SSL validation
`GOISILON_VOLUMEPATH`	which base path to use when looking for volume directories
`GOISILON_VOLUMEPATH_PERMISSIONS`	permissions for new volume directory
`GOISILON_AUTHTYPE`	what should be the auth type, session-based or basic

Initialize a new client with options

The following example demonstrates how to explicitly specify options when creating a client:

client, err := NewClientWithArgs(
	context.Background(),
	"https://172.17.177.230:8080",
	true,
	1,
	"userName",
	"groupName",
	"password",
	"/ifs/volumes",
	"0777",
	0)
if err != nil {
	panic(err)
}

Create a Volume

This snippet creates a new volume named "testing" at "/ifs/volumes/testing". The volume path is generated by concatenating the client's volume path and the name of the volume.

volume, err := c.CreateVolume(context.Background(), "testing")

Export a Volume

Enabling a volume for NFS access is fairly straight-forward.

if err := c.ExportVolume(context.Background(), "testing"); err != nil {
	panic(err)
}

Delete a Volume

When a volume is no longer needed, this is how it may be removed.

if err := c.DeleteVolume(context.Background(), "testing"); err != nil {
	panic(err)
}

More Examples

Several, very detailed examples of the GoIsilon package in use can be found in the package's *_test.go files as well as in the libStorage Isilon storage driver.
