A cloud.ca client for the Go programming language

How to use

Import

import "github.com/cloud-ca/go-cloudca"

/* import the services you need */
import "github.com/cloud-ca/go-cloudca/services/cloudca"

Create a new CcaClient.

ccaClient := cca.NewCcaClient("[your-api-key]")

Retrieve the list of environments

environments, _ := ccaClient.Environments.List()

Get the ServiceResources object for a specific environment and service. Here, we assume that it is a cloudca service.

resources, _ := ccaClient.GetResources("[service-code]", "[environment-name]")
ccaResources := resources.(cloudca.Resources)

Now with the cloudca ServiceResources object, we can execute operations on cloudca resources in the specified environment.

Retrieve the list of instances in the environment.

instances, _ := ccaResources.Instances.List()

Get a specific volume in the environment.

volume, _ := ccaResources.Volumes.Get("[some-volume-id]")

Create a new instance in the environment.

createdInstance, _ := ccaResources.Instances.Create(cloudca.Instance{
    Name: "[new-instance-name]",
    TemplateId: "[some-template-id]",
    ComputeOfferingId:"[some-compute-offering-id]",
    NetworkId:"[some-network-id]",
})

Handling Errors

When trying to get a volume with a bogus id, an error will be returned.

// Get a volume with a bogus id
_, err := ccaResources.Volumes.Get("[some-volume-id]")

Two types of error can occur: an unexpected error (ex: unable to connect to server) or an API error (ex: service resource not found) If an error has occured, then we first try to cast the error into a CcaErrorResponse. This object contains the HTTP status code returned by the server, an error code and a list of CcaError objects. If it's not a CcaErrorResponse, then the error was not returned by the API.

if err != nil {
    if errorResponse, ok := err.(api.CcaErrorResponse); ok {
        if errorResponse.StatusCode == api.NOT_FOUND {
            fmt.Println("Volume was not found")
        } else {
            // Can get more details from the CcaErrors
            fmt.Println(errorResponse.Errors)
        }
    } else {
        // handle unexpected error
        panic("Unexpected error")
    }
}
