A cloud.ca client for the Go programming language
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]",
})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")
}
