Feilong Go Client Library Examples

The examples provided here do only queries: they do not create, modify, nor delete resources. They can therefore safely be used in production environments.

How to Compile the Examples

From the examples directory, create a symbolic link to the snippet you want to use:

$ ln -s snippets/get_version.go main.go

Generate the go.sum file:

$ go mod tidy

Compile the example, it will go to $GOPATH/bin:

$ go install

How to Run the Examples

To run the example, you need to export the URL of the Feilong connector:

$ export ZVM_CONNECTOR="http://1.2.3.4"
$ example

Some snippets need a parameter on the command line. For example, if you compiled get_guest_info.go:

$ export ZVM_CONNECTOR="http://1.2.3.4"
$ example MYGUEST

If you implemented token authentication on the server side, you need to export one more environment variable:

$ export ZVM_CONNECTOR="http://1.2.3.4"
$ export ZVM_ADMIN_TOKEN="zvX2mFxuj8HcrYkAacLReV0RTQ0K5IIEighOR9F8AG"
$ example

If you mandated SSL on the server side, you might need to add your Certification Authority to the client. On a SUSE system:

$ sudo cp feilongCA.crt /etc/pki/trust/anchors/
$ sudo update-ca-certificates

$ export ZVM_CONNECTOR="https://1.2.3.4"
$ example
